|"Loyalty is what matters, and that exists now, not in the past. Loyalty has to be proved every day, in every piece of fresh-kill brought back for the Clan, every claw mark on our enemies, every patrol, every training session."|
|— Firestar in Sunset, page 240|
Firestar is a large, dark flame-colored tabby tom with a pale orange belly. He has short, sleek, and thick fur, large ears, a long tail, and bright, emerald-green eyes.
In the Super Edition Arc
- Moth Flight is overlooking Firestar's nine lives ceremony, and she spots an orange tom. She sees this cat getting touched on the head with several muzzles, a golden tom and a blue-gray she-cat are among them. Unbeknownst to Moth Flight, this process is that of a new leader receiving their nine lives. To Moth Flight, though, it looks like a bolt of lightning has been shot through the orange tom.
- Firestar is seen in the manga part of Tallstar's Revenge, when the Clans arrive at their new home by the lake. He drops wet moss at Tallstar's side, and is there with Onewhisker. They all look very worried, since Tallstar is very frail and will join StarClan soon. When Tallstar announces that Onewhisker will be WindClan's next leader, Firestar and Onewhisker are seen looking very shocked. Tallstar compares Firestar to Jake, and says he knew that Jake was his father, because of the resemblance. When Tallstar makes the journey to StarClan, Firestar is seen bending over him.
- After Yellowfang has been exiled from ShadowClan, she encounters Firepaw. After a brief fight, he overpowers her and gives her something to eat. She begins to think of the possibility of a new life for herself.
- Fireheart is mentioned, though not by name, in the manga at the end of the book when a RiverClan warrior meets with Crookedstar and tells him that a ThunderClan warrior had given Mistyfoot bad news about Silverstream.
- Although not mentioned by name, Rusty is described as a kittypet with a flame-colored pelt and green eyes, often sitting on a fence watching and pondering about the forest. Bluestar takes an interest in him after watching him while patrolling, seeing his potential. She also sees him attempting to catch a bird, which flies away. Bluestar mentions him to the medicine cat at the time, Spottedleaf, who seems to know pretty quickly why Bluestar is interested in the kittypet. Graypaw is asked by Bluestar to keep an eye on Rusty. It is revealed that Graypaw's encounter with Rusty wasn't an accident, but that it was ordered by Bluestar herself.
- At the very end of the book, Bluestar is thinking Goosefeather is right, and that a fire will blaze through the forest after all. Rusty only appears in the last chapter and the manga, when he is in the ThunderClan camp for the first time. From there, he is taught basic Clan Terminology by Lionheart. Bluestar holds an apprentice ceremony for Rusty, and he earns his name, Firepaw. Bluestar reminds herself of Goosefeather's prophecy, looking at Firepaw as though he is the fire that will blaze through the Clans.
- Firestar is constantly having dreams about some unknown fleeing cats. After a Gathering, he travels to the Moonstone to share dreams with StarClan. Upon arriving and falling asleep, he speaks to Bluestar, who tells him the cats he is having dreams about are the cats of ancient SkyClan, the fifth Clan of the forest, who were driven out by the other Clans. Firestar wants to help SkyClan, but Bluestar refuses because she wants him to stay and assist his Clan. Eventually, Firestar hisses at Bluestar and argues with her, then wakes up.
- Silverstream appears to Firestar in a dream, giving him a fish. Firestar is surprised at the taste, thinking that it is "warm and flavorful." She reminds him of the life that she gave to him: the life of loyalty to what he feels is right. This convinces him that StarClan wants him to complete this mission, to right the wrong they failed to stop so many moons ago.
- Firestar runs into Smudge while on a patrol and discovers that he is having similar dreams. That night, he decides to stay in Smudge's garden, where he then dreams of Cloudstar, the ancient leader of SkyClan. He is told that he is in the old SkyClan camp, and must make a journey to rebuild SkyClan. The next day he comes back to camp to tell Graystripe, Cinderpelt, and Sandstorm all he knows about SkyClan. At first they think that he is going to go back to being a kittypet again, but when he chooses Sandstorm to go with him on the journey, Graystripe and Cinderpelt agree to watch over the Clan while they're gone. Firestar also tells Graystripe that he wants only Sandstorm to go with him.
- Sandstorm and Firestar set out in search of SkyClan. Sandstorm suggests that they spend the night in an abandoned Twoleg nest, but as Firestar steps inside, he becomes frightened from his kittypet roots and insists that they find another place to rest. They get separated after a storm hits, and Firestar looks through all the Twoleg gardens to try and find Sandstorm. He eventually finds some cats in Twolegplace and they take him to a spot where they get their water, which is how he finds Shorty, who says he has seen Sandstorm and leads Firestar to her. He fears that she had died, and feels guilty because they had just argued about Spottedleaf. Soon they are reunited after Sandstorm saves him from a hostile kittypet.
- Firestar and Sandstorm make it to SkyClan's camp, where they meet an old cat named Sky (later renamed Skywatcher), the last cat alive keeping SkyClan's memory. Skywatcher asks Firestar to rebuild the Clan, and Firestar, feeling forced to say yes, obliges. Two kittypets named Cherry and Boris join the new SkyClan, and get their apprentice names, Cherrypaw and Sparrowpaw. Firestar finds enough kittypets, loners, and rogues around the area to rebuild SkyClan.
- Before Skywatcher dies, he tells Firestar the prophecy, which later makes in an appearance in the Power of Three Arc: "There will be three, kin of your kin, who hold the power of the stars in their paws." Later, Firestar comes back for Skywatcher and finds he he passed away. Firestar is saddened by this and takes him back to the camp to sit vigil.
- Sandstorm becomes very distressed when Spottedleaf comes to help her heal Patchfoot, and Firestar lets it slip that he and Spottedleaf had seen each other before in his dream. Sandstorm states that Firestar loves Spottedleaf and how the two had always seemed to belong together when Firestar first joined the Clan. Spottedleaf says that she couldn't choose a mate, even if she wanted to very much. Firestar also tells Sandstorm he would love her for all the moons to come and that she would never be second-best to him. Firestar reveals his love for Sandstorm belongs in the life they shared and would last for all the moons to come—basically he loves Sandstorm more than he will ever love Spottedleaf; Sandstorm is his one true love. Sandstorm accepts, although she gets slightly tense when Firestar brings up the name of Spottedleaf again.
- In a dream, Skywatcher also tells him about a medicine cat that he needs to find, and he travels to Twolegplace in search of whoever it is. He asks some cats if they have dreamed of strange things, and a kittypet named Echo says that she has. When she agrees to join SkyClan, he names her Echosong. The Clan finds a large barn full of angry rats that drove out ancient SkyClan. Firestar leads the Clan into attack against them, but Rainfur is killed during the battle, and Firestar loses a life — Sandstorm saves him from losing his other lives, and tells him she had to choose him over Rainfur. After he revives, Firestar and the other SkyClan cats climb a tree hanging above the barn. Firestar leaps into the barn and kills the lead rat, and all the other rats flee. After the battle, he helps Leafdapple earn her nine lives and become Leafstar.
- In the epilogue, Sandstorm gives birth to his two kits, whom they name Leafkit, in honor of Leafstar and Spottedleaf; and Squirrelkit, because of her bushy tail.
- Although not making any formal appearances, Firestar is mentioned various times throughout the book by Leafstar, and other SkyClan cats. He is thought of often, and is spoken of when Leafstar tells stories of how SkyClan was rebuilt. Stick also mentions him when he was trying to find Sandstorm and Firestar, and tells him that they must find the flame-colored cat.
- Firestar is seen hunting in StarClan. He stalks a squirrel in a tree until a voice interrupts him. Firestar scrambles down the tree and sees Bluestar at the foot of it. They talk about how the Clans were coping after the battle with the Dark Forest. Firestar mentions how he missed Spottedleaf and how she should have been there to guide him in StarClan. Bluestar says that one day his mate, Sandstorm, would be in StarClan with him. Another voice interrupts and Firestar sees Cloudstar, who thanks him for rebuilding SkyClan. Firestar tells him that's obviously not the reason he visits him. Cloudstar tells him a prophecy that needs to be passed to Bramblestar. The prophecy was confusing to Firestar: When water meets blood, blood will rise. He asks when to tell him, and Cloudstar tells him he will know. Firestar tells Cloudstar he trusts him but wishes that ThunderClan could have seasons of peace after all the suffering from the Great Battle.
- As Dewpaw lists the scratches that represent the fallen on the Stick of the Fallen, he mentions one of them stands for Firestar. Dewpaw says Firestar was the best in the forest and gave up his last life to save them. Bramblestar wonders if Firestar is watching over and now and approves of what he is doing. Jayfeather tells Bramblestar he misses the former leader too, and it was easy to tell he was thinking of him since he sighed when Dewpaw said his name. Jayfeather is sure Firestar is watching over. Bramblestar asks the medicine cat if he walked in his dreams, but Jayfeather says no. As Sandstorm talks to Bramblestar, her gaze clouds and Bramblestar wonders if she is thinking about Firestar. Bramblestar later makes sure not to mention Firestar’s decision to make Leafpool a warrior after learning about her kits. Bramblestar imagines how Firestar would make sure each of his Clanmates are coping with change. He thinks that Firestar wouldn’t start a fight and know how to keep the peace. Bramblestar knows that Squirrelflight lost so much during the Great Battle, including her father Firestar. At a Gathering, Blackstar lists Firestar as one of the fallen.
- After a ThunderClan patrol claims a large white bird for themselves after it crosses from the WindClan border, Sandstorm says Firestar would have let them have it. Bramblestar tells her he is not Firestar, and Gorsetail retorts he is definitely not Firestar. Sandstorm and Bramblestar talk about Firestar again with Sandstorm mentioning that Firestar found it hard when he lets his Clanmates face danger. He felt that since he had nine lives, he had lives to spare. Bramblestar thinks he is right and should be doing the dangerous duties. Once again Bramblestar wonders what Firestar would do in his situation, and thinks he wouldn’t have rescued and fed the kittypets. Bramblestar tells Jessy about Firestar and how he is missed. Jessy wishes she met the former leader, and Bramblestar thinks of how much prey he would give to have Firestar back. It’s explained more about Firestar to Jessy, with his former friendship with Onestar how he and Cloudtail are kin. Bramblestar thinks of how Firestar helped to bring Cloudtail back when he was taken by Twolegs. Squirrelflight says that Firestar would put his Clanmates first. Bramblestar decides that taking in the kittypets would be something Firestar would do, and Squirrelflight agrees.
- During a dream, Firestar appears to Bramblestar, reassuring there is no blood in the lake, his Clanmates are safe. Firestar says he is happy to be on the old territory. Bramblestar is relieved to see the former leader, and expresses his guilt over Seedpaw’s death. Firestar reassures she is safe in StarClan, and tells Bramblestar he needs to learn he cannot protect every cat. Firestar also mentions that Bramblestar is doing a good job and shouldn’t worry. Bramblestar wants to ask Firestar every question he had thought up since his death, but Firestar hushes him. He tells the leader that he knows the answers, they are in his heart. Firestar tells Bramblestar that he isn’t leader anymore, and should trust himself like the cats that gave him his nine lives. Firestar tells the prophecy he was given previously, urging Bramblestar to look at the water. He says that blood does not drown. He starts to fade, the prophecy repeating in Bramblestar’s head. Bramblestar calls a meeting about the dream and the prophecy, and Leafpool seems excited to know that Firestar is watching over them. Jayfeather isn’t as impressed, wanting Firestar to be clearer. Squirrelflight agrees that he could just straight out told them what to do.
- Bramblestar remembers that Firestar wanted his Clan to learn to tree-climb swiftly, but could never master it. Bramblestar mentions to Tawnypelt that Firestar taught him that compassion is a sign of strength. Tawnypelt snaps Firestar would have put the Clans first. Bramblestar again wonders what Firestar would have done if he is in his situation, but Sandstorm says he is asking the wrong question. Cloudtail remembers that his mother came from a Twoleg den, and so did Firestar. As Rowanstar confronts Bramblestar, he snaps that Firestar’s problem was he thought he knew what’s best for every Clan. Graystripe tells Bramblestar that Firestar would have done what he has done, but Bramblestar winces at what Rowanstar said. Graystripe tells Bramblestar that Firestar wouldn’t have seen saving ShadowClan from kittypets as intruding, but if he thought a Clan needed help, it was his duty to provide it. He says he would have followed Firestar, if he had a choice on the matter. Leafpool tells Bramblestar what Sandstorm already told him, that it doesn’t matter what Firestar would have done, but what he should do.
- Cloudtail feels depressed, admitting the battle seems long ago but Firestar leaving feels like it happened recently. Bramblestar feels hurt at first, but then remembers that the white tom and Firestar are kin. Cloudtail quickly tells Bramblestar he is doing a good job, and he just needs to trust Firestar made the right choices. On a patrol, Furzepelt teases that ThunderClan are missing Firestar so much, they are looking for a replacement from kittypets. Dewpaw is furious, telling the patrol to come over and insult Firestar’s memory. Later, Bramblestar has another dream. He looks around, expecting Firestar but instead of him, he talks to Yellowfang. He talks afterwards with Jayfeather about it, and the medicine cat is sure it connects to Firestar’s prophecy. Later, Sandstorm is telling Purdy a story about Firestar as an apprentice, possibly about his first meet with Yellowfang. After Bramblestar makes the decision to take his Clan to fight the badgers that are troubling ShadowClan, he admits to himself that Firestar wouldn’t have done it, only because he doesn’t have kin in ShadowClan. Bramblestar finally realizes Firestar’s prophecy, that he and Tawnypelt shared blood and their kinship survived the floods.
- After the battle with the badgers, Rowanstar tells Bramblestar to stop acting like Firestar and go away. During another dream, Firestar thanks Bramblestar for returning his Clan back to the hollow, since they had to move out because of the floods. Bramblestar points out it hasn’t happened yet, but Firestar tells him it will happen. Firestar commends Bramblestar on his work for the badgers, saying he did what he thought was right and the badgers would have made trouble for ThunderClan eventually. He sighs that few cats understand the importance of sharing the dangers that the Clans face. Firestar tells Bramblestar a great secret, that there was once a fifth Clan in the forest. He explains a little about SkyClan and his connection to him. He admits it was hard to leave his Clan to go on the journey. Firestar tells Bramblestar that fighting the badgers was right as ShadowClan couldn’t be driven out. He says it’s not up to one Clan to save the others; they all have to protect one another. He starts to fade, telling Bramblestar there is one other cat that knows of SkyClan. He urges Bramblestar if he has more questions to go and ask her.
- Firestar’s words echo in Bramblestar’s head, and he knows what cat Firestar meant. He announces to Sandstorm he had a dream about Firestar. Sandstorm admits she dreams of him all the time, but it’s not like he is really visiting. Bramblestar assures he is watching over, and sent him to talk to her. He asks about SkyClan, and Sandstorm fully describes her and Firestar’s journey. Bramblestar admits he is doing what Firestar would have done, but Sandstorm snaps Firestar didn’t appoint him to be his echo but his own leader. She asks if he would have done the same thing if there wasn’t any Firestar, and Bramblestar admits that he would have. Sandstorm tells Bramblestar he is leader now, not Firestar; he should be the leader he wants to be. As Graystripe and Sandstorm are about to have their elder ceremonies, Bramblestar is saddened that with Dustpelt and Firestar dead, they are the last of their generation. Sandstorm says she wishes Firestar is beside her, but knows he is watching over the entire Clan. After the ceremony, Bramblestar swears he can see Firestar and Dustpelt weaving around Sandstorm and Graystripe, but they are soon gone.
- During a Gathering, Firestar appears alongside the other cats that died because of the Great Battle. Firestar steps forward to talk to Bramblestar, saying that there is a way to honor all of fallen that stand with him. He urges Bramblestar to remember SkyClan and tells him that he has a chance to make sure what happened to them will never happen again. Because of this, Bramblestar makes a new addition to the warrior code: Each Clan has the right to be proud and independent, but in times of trouble they must forget their boundaries and fight side by side to protect the four. Each Clan must help the others so that no Clan will fall. Rowanstar snaps that Bramblestar is too much like Firestar and its like Firestar isn’t dead. Bramblestar declares Firestar is dead, and he is a different leader now.
- Coming Soon
In the The Prophecies Begin Arc
- Rusty is a kittypet who lives near the forest.
- Rusty the kittypet has a dream about hunting in the wilderness of the forest. He sees a mouse and attempts to attack it, but the crunching of his food being tipped into his bowl distracts him and the mouse escapes. Rusty wakes up and goes over to his food bowl, thinking about how tasteless the food was and how much he would love to eat mouse. He goes outside and makes his dirt. Then he sits on a fence post and looks out at the forest longingly. He decides to go and explore the forest. As he leaps down from the fence post, his neighbor, Smudge, hears his bell jangle and questions Rusty. Rusty explains he is going to explore the forest. Smudge is terrified, saying there are huge wildcats who live there, who sharpen their claws on old rabbit bones. He mentions a time where another kittypet by the name of Henry caught a bird in the forest. Rusty then comments on how Henry's trip to the cutter changed everything. Rusty is slightly nervous, but still goes to investigate with the memory of his dream and the exciting silence of a hunt.
- Rusty sees a real mouse in the forest. He is about to catch it when he hears a noise. Then he sees a bright ginger tail of a fox, and curiously follows it. Then a creature attacks him from behind, and Rusty is led into a fight. He bravely fights the creature. When Rusty gets the chance to see what animal it is, he sees it is a broad-headed gray tom, who is quite scrawny compared to Rusty. The cat starts talking to him, explaining that his name is Graypaw and he is a ThunderClan apprentice. Rusty is disappointed that this cat no longer wants to fight. Graypaw explains a bit about himself, but Rusty does not understand. Then Graypaw scents cats from his Clan nearby, and he tells Rusty to go, but it is too late. Bluestar and Lionheart, two ThunderClan cats, come into the area and question Graypaw about Rusty. Bluestar compliments Rusty on how well he fought and what a good hunter he was. Lionheart says that Rusty is simply a kittypet and he should be taken back to his Twolegs.
- Rusty feels upset and says he was only going to take a few mice. He says there is enough to go around. Bluestar is angry and declares that there is never enough to go around. Rusty is terrified at her rage. He apologizes and says he won't ever hunt in the forest again. Bluestar and Lionheart relax. Rusty asks Bluestar about Clan life and the rituals. Bluestar offers for him to join her Clan. Rusty is shocked and asks if he can come and tell them his answer next sunhigh. Bluestar agrees and Rusty returns home. Once he does, he informs Smudge that he met some wildcats in the forest and they said he could join the Clan. Smudge is shocked and says it is a bad trick. Rusty admits he trusts them and leaves Smudge. He meets Lionheart in the forest. Whitestorm, a senior warrior, is with him. Rusty is slightly nervous at tough-looking Whitestorm, but Lionheart tells him to relax. Rusty is taken through the forest to ThunderClan camp. Rusty knows it is ThunderClan camp because of the many different cat scents and paw markings on the ground.
- When Bluestar announces her intent to accept Rusty, many of her Clanmates are infuriated. A young warrior named Longtail taunts him, reminding his Clanmates that Twolegs would invade their territory because of Rusty's collar. Rusty attacks Longtail and hurts him, giving him a torn ear. Longtail tears off Rusty's collar with his teeth, and Bluestar accepts the broken collar as a sign that Rusty should be a Clan cat, and grants him his apprentice name, Firepaw, in honor of his flame-colored pelt.
- Firepaw is mentored by Tigerclaw and Lionheart, until he eventually gets a very shocking choice for an official mentor: Bluestar. The Clan is very surprised, as it is a high honor, but Tigerclaw remarks that Firepaw wasn't being punished by feeding the enemy warrior, Yellowfang. Bluestar chose him because of his exceptional skill that exceeds the other apprentices, and because she has a suspicion that he was part of the fire prophecy. Tigerclaw continually bullies him, as do the two older and more experienced apprentices, Sandpaw and Dustpaw. Graypaw stays by Firepaw's side all the time and they become best friends. Ravenpaw also becomes their friend, overcoming some of his timidness, but Tigerclaw, his taunting mentor, is still a big target of his nervousness. Firepaw catches on very fast to everything he is taught, and soon is considered as a warrior with leadership skills, gaining knowledge of Clan routines and heritage.
- Firepaw encounters a ShadowClan cat named Yellowfang, who is now living as a rogue since being unfairly driven out by Brokenstar, ShadowClan's leader. They battle, and Firepaw wins, injuring Yellowfang's leg in the process. Instead of turning her over to Bluestar, Firepaw feeds her before feeding his own Clan. After they both have eaten, they are caught by a ThunderClan patrol, which takes Yellowfang into custody. Firepaw's punishment for breaking the Warrior Code is to care for the grumpy former medicine cat.
- It becomes apparent to Firepaw that Ravenpaw, his timid friend, is in grave danger and cannot stay with ThunderClan, when he eavesdrops on Tigerclaw, Darkstripe, and Longtail's conversation about Ravenpaw being a traitor. Firepaw and Graypaw help him escape and live with a loner, Barley, spreading the rumor that their fellow apprentice had died. Firepaw is shocked and hurt when ThunderClan's medicine cat, Spottedleaf, is murdered by Clawface, a ShadowClan warrior. It is clear that he liked the she-cat, although he knew it was against the warrior code to do so, as medicine cats are not allowed to have mates. Later it is revealed that they both were in love with each other.
- Bluestar sends Firepaw and Graypaw into ShadowClan territory to find and question Yellowfang and attempt to recover Frostfur's stolen kits. It is later realized that Yellowfang didn't murder Spottedleaf like expected, but Clawface, one of Brokenstar's followers did. Following the successful mission, Bluestar grants Firepaw the name Fireheart and the status of a warrior along with Graypaw, who becomes Graystripe. As he starts his vigil, he notices Tigerclaw's eyes shining back at him. He then reveals silently that he had made an enemy out of the Clan deputy, as Tigerclaw did the same for him.
- At the start of the book, Fireheart dreams about a screeching cat, but he is quickly awoken.
- Fireheart and Graystripe are sent by Bluestar to find WindClan, who has been driven from their land by ShadowClan, as their first warrior assignment. The missing Clan is found and returned, with help from Ravenpaw, as he let the Clan shelter in his barn through the rain. They are then accompanied back to ThunderClan territory by two WindClan cats, Onewhisker and Deadfoot. Fireheart, Graystripe and the two WindClan cats are caught trespassing on RiverClan territory, and a fight brews. During the battle, a RiverClan warrior named Whiteclaw falls to his death at the bottom of the gorge. This death is blamed on Graystripe, who had been battling Whiteclaw, but had tried to catch his falling enemy. During the fight, Fireheart saves Sandpaw from falling over the side of the gorge. She snaps at him, not noticing how close she came to death, telling him that she could fight her own battles. Afterwards, she realizes what he did, and slowly begins to warm up to him.
- When the pair arrive back at camp, Fireheart is given his first apprentice, a she-cat named Cinderpaw, one of the kits he had previously rescued from ShadowClan. Graystripe also is given an apprentice, Cinderpaw's brother, Brackenpaw.
- On a training session, Fireheart spots a familiar kittypet. When Cinderpaw says that they should drive her away, Fireheart purposely steps on a twig to scare the kittypet away. Fireheart comes to the realization that the pregnant she-cat they saw is Fireheart's sister, Princess. Fireheart starts to visit her and tells her about his life as a warrior.
- One day, Graystripe and his apprentice, Brackenpaw, go hunting with Fireheart and Cinderpaw near the frozen river. When Graystripe begins to stalk a vole across the river, the ice shatters beneath him. A RiverClan she-cat ends up saving him, introducing herself as Silverstream. This leads Graystripe to fall in love with her, and the two begin meeting secretly, much to Fireheart's annoyance. The two friends begin fighting, and soon stop speaking to one another.
- Fireheart fetches as much catnip as he can to help Yellowfang during a bout of greencough that threatens the camp and takes one of Bluestar's lives. After he delivers the catnip to Yellowfang, he goes out to find Cinderpaw, who is gravely injured from a monster on the Thunderpath. He spills out all his worries to Princess, whom suggests that it might be a trap that Tigerclaw set up for Bluestar.
- While hunting, Fireheart decides to visit Princess, whom he knows is close to kitting. Princess gives him her first-born son, Cloudkit, to take back to ThunderClan, and to be raised as a Clan cat. Fireheart had told Princess all about his life in the Clan, and after hearing that Cinderpaw had been hit by a monster, she wants Cloudkit to be his new apprentice. When Fireheart arrives back at camp, the Clan is furious to see that he has brought a kittypet to their Clan. Graystripe speaks up in Fireheart's defense, and Bluestar decides to let the kit stay with ThunderClan. Brindleface, a ThunderClan queen who had lost one of her kits, decides to care for Cloudkit. Fireheart visits Cinderpaw frequently, even when she is sleeping, and tries to convince her that she isn't a burden to ThunderClan.
- When Brokenstar, the former leader of ShadowClan, returns with a group of rogues, Fireheart is the only fully trained warrior in the camp. While Fireheart is fighting, he sees Clawface and starts battling him fiercely because he killed Spottedleaf. Graystripe then kills him. The handful of able fighters manage to drive the rogues away, and Brokenstar is blinded by Yellowfang during the battle, thus unable to make his escape. Bluestar decides that the Clan would have mercy and keep him as a prisoner rather than slaying a helpless cat, and she changes his name to Brokentail. Fireheart tells Bluestar about Sandpaw's and Dustpaw's strength and courage in the battle. After this, Sandpaw and Dustpaw receive their warrior names: Sandstorm and Dustpelt. The next day, Bluestar goes to Fireheart and tells him that he and Graystripe have to go hunting, since she hasn't seen the old friends eat together for a long time, and there shouldn't be any fighting between them. Fireheart informs Graystripe, who is moving snow away from the nursery, and Graystripe refuses to hunt. Fireheart tells him that Bluestar sent them to hunt; Graystripe agrees reluctantly but snarls that he has to do everything Bluestar says. Graystripe attempts to prove himself to Fireheart during the hunt. Fireheart protests that he doesn't have to prove himself, and when the hunt is over, he notes that Graystripe caught more than he did.
- When RiverClan and ShadowClan ally to attack WindClan, ThunderClan warriors are sent to aid them. During the battle Fireheart permits Silverstream, Graystripe's forbidden lover, to escape. Darkstripe sees this and quickly tells Tigerclaw, who views it as a defect in Fireheart's loyalty. After the battle, Graystripe thanks Fireheart for not attacking Silverstream and the two quickly rekindle their friendship.
- After one of the Gatherings, Fireheart and Graystripe sneak away to WindClan territory to find Ravenpaw, and confirm his story of the death of Redtail. When they find him, they question him about what he saw during the battle where Redtail was killed. Ravenpaw explains the story once more, and that Oakheart died from a rock fall, not killed by Redtail, but it was partly his responsibility that he died. Ravenpaw also mentions that Oakheart was fiercely protective of Stonefur before he died, hissing at Redtail when he attacked Stonefur. Fireheart is confused, saying that there are battles all the time. They eat mice, and when returning to camp, Tigerclaw sees them and comments that they have no fresh kill. Fireheart lies that they ate to kept their strength up. Tigerclaw refuses to believe that and takes the pair to Bluestar. She is disappointed and orders them to hunt until sunhigh the next day.
- Fireheart wants a RiverClan warrior to confirm Oakheart's death, one who had been there. He speaks his fears to Graystripe, who tells him that there is a warrior that he can speak to. Fireheart guesses that it is Silverstream, while Graystripe nods his approval.
- The next day, in RiverClan territory, Fireheart and Graystripe hide until they reach the camp. They spot Silverstream with Blackclaw and his apprentice, and Silverstream tells him that she's going to look for a mouse in the bushes. Blackclaw gives a mew of approval before racing in the bushes. Graystripe explains Fireheart's fears to Silverstream, and then she gets Mistyfoot to speak to them. Fireheart learns that Oakheart was Mistyfoot and Stonefur's father, and Graypool was their mother, but it still didn't explain why Oakheart had warned Redtail that no ThunderClan warrior would ever harm Stonefur. Mistyfoot tells Fireheart that Graypool can meet him and Graystripe on the half-bridge the next day. Fireheart agrees and he takes off with Graystripe. The next day they reach the half-bridge. He and Graystripe see Graypool appearing with Mistyfoot and Silverstream, complaining it is too cold to go out in the weather. Silverstream replies that it is nonsense, and that it was a warm day. Graypool later sees Fireheart and Graystripe and exclaims that there were ThunderClan warriors here, and she could rip their fur out. When Fireheart explains he was only here to talk, Graypool shoos Silverstream, Mistyfoot, and Graystripe away. Fireheart explains the story about Oakheart's death. Graypool tells Fireheart that she isn't the pair's mother; a ThunderClan cat was. She tells him that Oakheart found two kits in the snow, and the two scraps wouldn't see sunrise if it wasn't for her. She suckled them, and then noticed there was a scent underneath their snowy coats -- ThunderClan. Fireheart thanks Graypool for explaining it all then goes back to camp with Graystripe.
- While on the patrol at the RiverClan border, they see the flood and how horrible it is. They also see two kits struggling on a bundle of sticks and Twoleg rubbish. They rescue the kits and are spotted by a RiverClan patrol. Graystripe and Fireheart are astonished by how the flood waters caused so much damage that they had to move their camp. Leopardfur takes them to Crookedstar, who makes Fireheart and Graystripe explain the story. Though Blackclaw is hostile towards them and accuses them of trying to steal the kits. Crookedstar slowly believes the ThunderClan cats, with Graypool's help. Fireheart and Graystripe persuade RiverClan to let them catch ThunderClan prey and help RiverClan's starvation, as Graypool explained that they were nearly dying from hunger.
- A few days later, Fireheart wakes Graystripe up and reminds him they need to go hunting for RiverClan. Cloudkit follows them out of camp, but Fireheart catches him in time. Graystripe remarks hotly, "Why does your kin have to show up at the weirdest times, Fireheart?" Cloudkit wonders where they're going, and Fireheart replies that they're going on a special warrior mission. Graystripe adds that it isn't for pesky kits. Instead of following them, Cloudkit scampers back to the nursery.
- They hunt for RiverClan and take the prey to them. Stonefur welcomes them and tells Graystripe to take prey to the queens, and tells Fireheart to take prey to the elders. Fireheart meets back up with his friend after giving his prey to the elders, and figures out that Silverstream is expecting Graystripe's kits. Fireheart is uneasy and scared, but Graystripe is enthusiastic and happy about it. When Fireheart and Graystripe return to camp, Tigerclaw finds them with Cloudkit at his side, learning that Cloudkit boasted about everything to the deputy. He goes to the leader's den with Tigerclaw, Cloudkit, and Graystripe. Bluestar is extremely disappointed with them, and tells Cloudkit he can continue with his elder duties. Cloudkit doesn't seem to mind, as he likes caring for the elders. The blue-gray leader punishes the pair of warriors by making them apprentices for a half-moon once more, including sleeping in the apprentices' den, responsible for the elders; with Longtail to supervise their first hunting session.
- Silverstream gives birth to Graystripe's kits at Sunningrocks, with Fireheart running to summon Cinderpaw, the new medicine cat apprentice. Though Silverstream dies, Graystripe's two kits, Featherkit and Stormkit, survive. Cinderpaw blames herself for the death of Silverstream.
- When Bluestar is checking on the nursery, Bluestar explains to Fireheart that she is the mother of Mistyfoot and Stonefur. Fireheart is shocked as he learns the story how Bluestar had given up her kits to save ThunderClan from Thistleclaw. She had three kits. One had died because of extreme cold, while the other two were living in RiverClan.
- While Fireheart takes out Cloudpaw, who has been named his apprentice, Cloudpaw is very scared and points that Tigerclaw is leading a patrol of rogues directly to ThunderClan's camp. The two cats follow him, then realize that this was why he sent all those patrols, and sent Fireheart to watch Cloudpaw, to plan an attack on ThunderClan with Brokentail and his old allies. Fireheart stops Tigerclaw from killing Bluestar and finally exposes his treachery. Tigerclaw is exiled from ThunderClan by orders of Bluestar. As he leaves, he threatens Fireheart's life. To Fireheart's and the Clan's astonishment, Bluestar makes Fireheart deputy, instead of an older warrior. However, she violates the warrior code in that she named her new deputy after moonhigh. Many believe this is a bad omen, and are skeptical about their new deputy.
- Graystripe admits that Fireheart is right. He can't leave his kits in another Clan, so he goes with the RiverClan patrol, which includes Mistyfoot, Silverstream's cousin and best friend, to RiverClan to stay.
- Fireheart struggles with his deputy duties, much to the amusement of Darkstripe. Fireheart is also still mentoring Cloudpaw, who is being difficult. Bluestar is still traumatized from the disloyalty of Tigerclaw, to the point where she is barely eating.
- Fireheart and Bluestar attempt to travel to Highstones. On the way, they are stopped by a WindClan patrol led by Mudclaw. The WindClan warriors do not let them pass, and eventually, Fireheart and Bluestar return to camp. The Clan is outraged, and they demand to know why Fireheart allowed the WindClan patrol to turn them back. Fireheart responds with a challenge of his own, asking, "Would you have risked your leader's safety?"
- Two ShadowClan warriors, Littlecloud and Whitethroat, come into ThunderClan territory, pleading for help. ShadowClan has fallen ill, and Nightstar is dying. Yellowfang tells Bluestar to send the warriors away, because they have a dangerous disease with no known cure, and desperately reminds Bluestar that it had not been long since greencough had taken one of her lives. Fireheart and Sandstorm escort the ShadowClan warriors to the Thunderpath, where they find the tunnel under the Thunderpath inside of ShadowClan's territory. Bluestar tells him and Sandstorm not to inform the clan about the tunnel. Fireheart soon finds out that Cinderpelt has been taking care of Whitethroat and Littlecloud, despite Bluestar sending them away. He tells her that the ShadowClan cats must leave the territory.
- A patrol comes back with battle wounds. Runningwind, who is part of the patrol, does not return. Fireheart returns to the scene of the attack, not knowing that Tigerclaw had led rogues to attack ThunderClan. Fireheart chases Whitethroat onto the Thunderpath, where he is hit by a monster. Tigerclaw attacks. Fireheart defeats him with the help of Stonefur's patrol, Tigerclaw then tells Fireheart that he will kill ThunderClan warriors one by one.
- Cloudpaw has been traveling to a Twoleg nest everyday, getting food from the Twolegs. When Fireheart finds out, he tells him to stop, but the apprentice refuses to listen, not understanding how far he was breaking the Warrior Code. Fireheart and Sandstorm follow him on one of his "outings," and helplessly watch as the Twolegs put Cloudpaw in a cage, and take him away in a monster. Fireheart says that he has lost everyone important to him in his Clan, and Sandstorm, who apparently has feelings for him, says that she had thought she had mattered to him, but that she must have been wrong. Fireheart feels bad, because the two had been growing very close. He apologizes at the fresh-kill pile, and is embarrassed to realize that his interactions with Sandstorm have been an interest to his Clan.
- Soon after, Ravenpaw visits ThunderClan, but as he traveled through the forest to ThunderClan's camp, he is attacked by Fireheart, Sandstorm, and Brightpaw, who had not recognized Ravenpaw at first. Ravenpaw tells Fireheart that he found a white kittypet that was lost, and smelled of ThunderClan. Fireheart sends Brightpaw back to camp to tell Whitestorm where he has gone, and Ravenpaw takes Fireheart and Sandstorm to the Twoleg Nest. On the way, they are chased by some dogs. Sandstorm becomes suspicious of Ravenpaw, questioning whether or not he was leading them into a trap. Fireheart thinks that her fears are ridiculous, and he continues to follow Ravenpaw to Cloudpaw's Twoleg Nest. There, they rescued Cloudpaw from his captivity. On the way back to camp, they are attacked by Mudclaw, his apprentice, Webpaw, and the WindClan deputy, Deadfoot. After the battle, Fireheart brings Cloudpaw to camp, and asks Bluestar if he can stay. Bluestar agrees, and Fireheart suggests that Darkstripe tell the Clan that Cloudpaw will stay, as Darkstripe had been the cat to protest. Bluestar seems disturbed by his coming, but tells him that Darkstripe will tell the Clan.
- Later that night, Fireheart is woken up by the smell of fire and alerts his Clan of the danger. When everyone is evacuating, they realize that Bramblekit is missing, along with Patchpelt and Halftail. He and Yellowfang return to camp and find Bramblekit stuck in a burning tree. Fireheart rescues him, and the tree falls, separating him from Yellowfang. He drags Patchpelt to the river, hoping to save him, but the elderly tom dies. They take shelter in the RiverClan camp. The next day, he and Graystripe head back to camp. Fireheart finds Yellowfang dying. Yellowfang tells him that she killed her son, Brokentail, not knowing that he already knew this. She asks Fireheart to thank Bluestar for allowing her to stay in ThunderClan, and admits that she wishes that Fireheart was her son. She dies shortly after this.
- At the end of the book, Fireheart takes his Clanmates to the gathering, because Bluestar had refused to go. When they arrive, they find that Nightstar had died, along with his deputy, Cinderfur. This confuses Fireheart, as Nightstar only received his nine lives and name at the Moonstone a few moons ago. When the new ShadowClan leader finally arrives, Fireheart is horrified to find that Tigerclaw is ShadowClan's new leader.
- Several hunting and border patrols find remains of rabbits and fresh-kill, along with evidence of a dog by Snakerocks. Bluestar believes it is WindClan, despite Fireheart's warnings that it is actually a dog. She plans to attack, but Fireheart comes up with a plan to divert the battle behind Bluestar's back, by traveling to WindClan to speak with Tallstar and ask him to have a peaceful meeting with Bluestar to work things out between the two rival Clans. He asks WindClan to have Ravenpaw be the messenger to ThunderClan from WindClan. When he tells the rest of the warriors about what he has done, and asks for their help, most of them are angry, including Sandstorm, who even asks Dustpelt to tell him what a stupid idea that was, but to Fireheart's dismay he agrees with his plan.
- The apprentices Cloudpaw, Brightpaw, Swiftpaw, and Thornpaw are long overdue for their warrior ceremony, but when Fireheart asks Bluestar about it, she says that only Cloudpaw will be made a warrior, as all the others' mentors are "traitors." Fireheart tries to convince her to rethink it, but she remains stubborn, and soon holds Cloudpaw's warrior ceremony, naming him Cloudtail.
- Two apprentices, Brightpaw and Swiftpaw, devise a plan to rid the Clan the problem of the dog at Snakerocks and tells it to Ashpaw, Fernpaw, and Thornpaw. Swiftpaw says that if they get rid of it, Bluestar will notice them, and they'll be made warriors. In the end, the only ones to go through with it are Brightpaw and Swiftpaw. But what they find at Snakerocks isn't just a dog; it's a whole pack of them. Fireheart learns from Fernpaw the following morning where the missing apprentices went, and Cloudtail swears to "shred anything that's hurt Brightpaw." When they got there, they noticed Swiftpaw was killed, and Brightpaw was badly injured, as Cinderpelt was unable to save her eye and ear, and she was terribly scarred.
- When the time comes for Bramblekit and Tawnykit to become apprentices, Fireheart asks Bluestar to choose mentors for them, but she tells him to choose. He chooses to be Bramblekit's mentor himself, and Brackenfur to mentor Tawnykit, even though Sandstorm was the obvious choice. She is furious at him for this and makes it a point to ignore him afterward. Fireheart cannot tell Sandstorm why he chose Brackenfur as Tawnykit's mentor: he wishes to protect her from Tigerstar, as he is afraid that the ShadowClan leader will harm the mentors of his kits.
- Fireheart finds out that Tigerstar is feeding a pack of wild dogs that had killed Swiftpaw and brutally injured Brightpaw earlier in the book. They find a trail of killed rabbits leading to the ThunderClan camp as Tigerstar's bait for the dogs, and at the end of the trail, the queen Brindleface, brutally murdered to give the dogs a taste for cat blood. Cloudtail is outraged when he discovers this, claiming he would flay Tigerstar, and scatter his entrails from the ThunderClan camp to Highstones. Tigerstar's intention was for the dogs to devour the ThunderClan cats after learning to like cat blood. Fireheart and a few other cats attempt to break the trail up, but the blood has already stained the ground and the dogs are still surely going to come to the camp, so they give the call to evacuate. Every cat except for a select few, Fireheart being one of them, leaves for Sunningrocks. Fireheart tells them to climb a tree once they get there. Before they leave to get rid of the wild dogs, Fireheart reveals to Sandstorm his love for her.
- At the end of the book, while Fireheart is trying to get the wild dog pack to go over the gorge, Tigerstar stops him and pins Fireheart down. Bluestar shows up and knocks the dog that is attacking Fireheart over the edge of the gorge along with herself. Fireheart tries to save her by jumping in after her, but he almost drowns. Mistyfoot and Stonefur appear and, since they are RiverClan cats and swim well, help Fireheart carry Bluestar up on to the bank where the ThunderClan leader shares tongues with her children one last time. Bluestar dies, but not before telling Fireheart that he is indeed the fire that was prophesied to save ThunderClan. After his leader's death, Fireheart looks at Graystripe. Graystripe dips his head in the deepest respect, and Fireheart is horrified because he realizes he is now the leader of ThunderClan, and has lost the easy friendship he shared with Graystripe.
- After Bluestar's death, he travels to the Moonstone with Cinderpelt for his leadership ceremony. He receives his first two lives from Lionheart (courage) and Redtail (justice). Then he thanks Fireheart for "Revealing the truth when no other cat could." His next four were from Silverstream (loyalty to what is right), Runningwind (energy), Brindleface (protection), and then Swiftpaw (mentoring). Fireheart apologizes to Swiftpaw; however he is seen as having no anger in his eyes, only "wisdom beyond his age." The ceremony then continues, and Fireheart receives his next two lives from Yellowfang (compassion) and Spottedleaf (love). She then tells Fireheart to "use it for the cats in your care -- especially Sandstorm," confirming that his love for Sandstorm and they becoming mates was okay with her. His final life is given to him by Bluestar, and with her life she gives him nobility, certainty, and faith. Once Firestar receives his leader name, the ceremony is interrupted with chanting and by a pile of cat and prey bones rising out of the ground. Bluestar then gives him this prophecy: "Four will become two, Lion and Tiger will meet in battle, and Blood will rule the forest."
- Then blood flows out of the hill and he thinks he is going to be swept away by the rushing current. When he wakes up he imagines that he can still smell the stench of blood. On their way back they stop at the barn where Barley and Ravenpaw live and catch a few mice.
- He gets back and Brackenfur wildly apologizes to him because he let Darkstripe, whom he was watching, out of his sight when Sorrelkit was fed the deathberries. Later, he exiles Darkstripe for his betrayal to ThunderClan, when he tried to kill Sorrelkit with deathberries after she had tracked him meeting up with Blackfoot, the ShadowClan deputy. Cloudtail complains about the cruelty of Lostface's name and asks if it could be changed. Firestar asks if that is possible and is told by Cloudtail if he thinks that Halftail and One-eye were born with those names, he's crazy. Firestar then goes to One-eye and is told how to perform the name-changing ceremony. Later, he renames Lostface as Brightheart.
- Firestar and Sandstorm are apparent mates now. Though it is not directly stated until later books, Cinderpelt is in love with the ginger leader, though he never knows. She seems to flare up at Sandstorm a few times, but eventually the two warm up and become great friends.
- Meanwhile, Tigerstar, leader of ShadowClan, tries to unite all four of the original Clans to form TigerClan. Only Leopardstar joins him, showing bad judgment as a leader. Tigerstar also brings BloodClan into the forest. He brings Scourge and BloodClan to a Gathering.
- Scourge believes that Tigerstar is just a normal Clan leader, but then Firestar reveals to all the Clans, including BloodClan, Tigerstar's treachery, and Scourge then rips all of the ShadowClan leader's lives away when Tigerstar acts like Scourge is under his control.
- Suddenly, Firestar realizes that Scourge is the real enemy. After wondering for a while what Scourge's weaknesses in battle are, Barley and Ravenpaw come to ThunderClan. Barley then tells him that he used to be a member of BloodClan, and that it was not a Clan at all, really, just a gang of vicious cats who fight for their own survival. Then Barley tells Firestar that Scourge's weakness is that he doesn't believe in StarClan. At first, Firestar is confused, until Barley explains that Scourge has one life, while Firestar has nine. Then, Firestar realizes how he can beat Scourge. He then convinces RiverClan's leader, Leopardstar and ShadowClan's leader, Blackfoot to join LionClan in the fight against BloodClan. They both agree, and the battle preparations began. He decides to teach the kits basic self-defense moves, and while training them, Sandstorm mentions how she would love to be Sorrelkit's mentor.
- On the day of the battle, Firestar declines Scourge's offer, and the battle commences. Darkstripe is killed by Graystripe, and then that causes them to notice that Whitestorm is injured heavily by Bone, and Firestar rushes to his side. Whitestorm then tells Firestar that he knew he wanted Graystripe as his deputy. He then names Graystripe the new deputy, and when he asks if he's sure, Firestar responds, "Never surer."
- Once he finds Scourge, the two begin battling. Scourge delivers a mortal blow to Firestar, causing him to lose the first of his nine lives. He is then met by Bluestar and Whitestorm, who inform him of his lost life. He then sees a faint outline of himself among the starry masses. Once he has healed, he goes back after Scourge. Scourge is blown away, as he believed Firestar to be dead. Firestar ends up killing Scourge, effectively ending the battle and ensuring peace in the forest at last.
In the New Prophecy Arc
- Mentioned by Cloudtail after Brambleclaw receives his dream from Bluestar, Cloudtail complains that Brambleclaw was muttering in his sleep, rudely comparing him to Firestar.
- He then gives Sorreltail her long-deserved warrior name at sunset, as the stars were coming out. Right after the ceremony, he goes up to Brambleclaw, telling him he hunted well that day. Suddenly, he asks Brambleclaw if he misses Tawnypelt. Brambleclaw replies that he does, and Firestar says that he understands, since he realizes how close Squirrelpaw and Leafpaw are. He also admits that he misses Princess, too. He then leaves, and Brambleclaw wonders whether to tell him about the prophecy, but decides not to, since Firestar didn't receive anything.
- He orders Thornclaw, Brambleclaw, and Ashfur to patrol Snakerocks. Squirrelpaw goes with them and they discover a badger's nest near Snakerocks. When the patrol tells Firestar, he decides to keep a watch out for it.
- Squirrelpaw gets punished for leaving with them and she has to serve Speckletail. Speckletail tells her stories about when Firestar was a young apprentice. During the Gathering, Firestar speaks first, telling the Clans about Sorrelpaw getting her warrior name, Sorreltail. He congratulates Hawkfrost for becoming a warrior.
- He wants to check the border between ShadowClan, but Brambleclaw contradicts him, saying that they should check the border with WindClan, instead. Firestar stops to listen, and slowly agrees, sending the cats off to the border of WindClan.
- Ravenpaw comes to visit Firestar, warning him about different monsters nearing the forest. Firestar receives the prophecy about the fire and the tiger from Cinderpelt and Leafpaw, he tries to keep Brambleclaw and Squirrelpaw away from each other. He is rather harsh on them, ordering them to go on patrol, or to gather moss for the elders. He tries hard, for he thinks danger would come to the Clan if they were together.
- After many attempts to keep the two cats away from each other, he fails. Firestar is very stressed out after their disappearance, and sends many patrols out to find the two. He often thought that he shouldn't have kept them apart from each other. He often blames himself that Squirrelpaw and Brambleclaw have gone missing. Sandstorm reveals that the fire might not have meant the end of the Clan, but it could have meant that Brambleclaw and Squirrelflight would work to keep the forest from danger. Firestar nods in approval, understanding, and waits patiently for them to return.
- At the end of the book, Firestar and a couple other cats witness one of the first monsters that traveled away from the Thunderpath, and sent the first damage to ThunderClan territory by running over a tree.
- Firestar starts to become more and more worried about many things. Firestar is worried about the Twoleg construction, and is afraid that the forest has become too dangerous to live in. The forest is becoming a bad place for ThunderClan to live in, and the monsters are destroying more of the Clan's territory. Firestar is also very worried about his daughter, Squirrelpaw, who had left with Brambleclaw, without telling anyone where they went. Graystripe helps the troubled leader cope with the disappearance, because Graystripe knows what it was like to live without a loved one. His other daughter, Leafpaw is trapped by Twolegs, while Sorreltail is powerless to help.
- Firestar is seen as he pads beside Sandstorm, who asks if he thinks their daughters would find their way home. He flinches, but says that they could only pray they would. When Sandstorm asks Graystripe if they would manage to find them, the tom says they would. Growling, Firestar demands how he could be so sure. He suggests sending another patrol to search for Leafpaw. Sandstorm mentions that ThunderClan had lost so many cats through the current moon, causing Firestar's gaze to harden as the wind carries her voice. He says that the other Clans may agree to join together to face the Twoleg threat.
- As Dustpelt objects, Firestar insists that no Clan would order the others, reasoning that leaf-bare was close and that ThunderClan couldn't fight it alone. Suddenly, a roar echoes through the four oaks of Fourtrees, and Firestar slows down. When Graystripe yowls that something was happening at Fourtrees, Firestar leads his Clan to the steep-sided hollow. After the oaks are cut down, Sandstorm murmurs that there was no hope. Firestar's eyes glint as he reassures his mate to have courage. He turns to face his Clan and says that they still have their Clan and there is always hope.
- When the monsters are moving too near to the ThunderClan camp, Firestar has to move the Clan to Sunningrocks. Then, Squirrelpaw and Brambleclaw return from the Great Journey, and, though he is overjoyed to see them, he is not completely sure about their idea of leaving.
- Firestar is devastated when he finds out his friend, Graystripe, was captured by Twolegs, but his grieving is interrupted by Tawnypelt, who begs them to help save ShadowClan when their camp is being terrorized by monsters, and he brings some of his cats to help. Soon after beginning of their trek, Firestar sees a tree falling near Onewhisker, so he pushes him out of the way along with some ShadowClan kits. Though he saves others' lives, that does not prevent him from losing yet another life, leaving him only six. Firestar allows ShadowClan to stay with ThunderClan until it is time to leave. Firestar helps the Clans leave the forest and remains optimistic during most of the journey.
- When the cats are at the lake, Firestar makes his daughter, Squirrelpaw, into a warrior, Squirrelflight. Onewhisker, along with Firestar and Brambleclaw, is told that he is to become deputy just before Tallstar's death. Barkface arrives soon after and believes that what the ThunderClan cats say about Onewhisker is true. Firestar tells WindClan about their new leader for Onewhisker in fear that no one would believe him.
- On the night Mudclaw revolts, Firestar brings help to WindClan, and helps to drive away Mudclaw and his attempt to overthrow Onewhisker. He wrenches his shoulder, because he was battling two cats at once.
- ThunderClan seem to be settling in their new home by this time. Firestar has still not appointed a deputy, with the faint hope that Graystripe may still be alive. ThunderClan has problems on their border with WindClan, though. Blackstar can't seem to contain his warriors, as it is ShadowClan that is the problem.
- Firestar is also worried about Onestar and how his Clan are getting along. He sends some cats over to ask how they were doing, only to be told that Onestar can deal with his own Clan and their problems alone.
- One night, badgers attack the camp as payback for them driving them out. Firestar fights alongside every warrior, and almost loses the fight. He would have lost, if it weren't for WindClan, who send a few warriors to help. This act loosens some of the tension between Firestar and Onestar. His daughter, Leafpool, and her forbidden love, Crowfeather, also come back to ThunderClan to fight the badgers. Firestar grieves for his former apprentice, Cinderpelt, when she dies protecting a kitting Sorreltail from the badgers.
- After a long convincing by Sandstorm, Brambleclaw, and Stormfur, Firestar has to accept Graystripe's death and move on. He is close to appointing Brackenfur as his deputy, until Leafpool approaches him and tells him about her dream that Brambleclaw would protect the Clan. Firestar then names Brambleclaw his deputy, stating that he would mentor Berrykit when the kit was six moons old.
- After Stormfur and Brook are exiled from RiverClan, Brambleclaw takes them back to the ThunderClan camp, thus sparking an argument about whether the former tribe cats should stay in ThunderClan or leave. Finally, Firestar snaps that the meeting is over and retreats to his den. At first Brambleclaw is shocked because Firestar never snaps out orders, but then Brambleclaw decides that it is because he must feel some loyalty to his lost friend, Graystripe, so he has taken in his son, or another possibility is because of Firestar's kittypet heritage.
- Firestar later gets caught in a fox trap when he is told by Birchpaw that Blackstar was on ThunderClan territory. It turns out to be a trap from Hawkfrost, who wants Brambleclaw to kill Firestar and become leader. Brambleclaw refuses and digs up the end of the trap, killing his half brother in the process. Firestar thanks Brambleclaw for showing his loyalty to the Clan and for not killing him.
In the Power of Three Arc
- Firestar's duties continue as he witnesses the apprenticeship of his grandchildren, Hollykit, Lionkit, and Jaykit. Firestar is the only one who knows that these three kits have the power of the stars in their paws.
- Although his grandson, Jaypaw, is blind, he allows him to train as a warrior. When Hollypaw wants to quit being a medicine cat apprentice and train as a warrior, at the same time Jaypaw wants to leave his apprentice life behind, Firestar is skeptical that it wasn't planned, but goes along with it and allows Hollypaw to train as a warrior and Jaypaw as a medicine cat. He assigns Brackenfur as Hollypaw's mentor rather than Jaypaw's warrior mentor, Brightheart.
- After many moons, Firestar's best friend, Graystripe, finds his way back to the Clans with his new mate, Millie. Even though he is pleased to see his friend, Firestar must choose who will be ThunderClan's deputy. During the process of thinking it through, his daughter, Leafpool, tells him that it was his decision. He realizes that that decision is probably for the best because Brambleclaw has been around their new territory longer and knows what is going on in the Clan.
- When Jaypaw tells Firestar and Sandstorm of Tallstar's warning to Barkface about the dogs, Firestar ignores his warning, telling him that StarClan could be telling them to keep the look out for dogs, not take WindClan's territory, which was Jaypaw's goal.
- Near the beginning of the book, Hollypaw tells Berrypaw to only look at RiverClan territory, and not to hunt, and Graystripe teases Firestar by telling him that Hollypaw was competing with him for leadership. Firestar tells Graystripe that he doesn't have to worry until she's bigger.
- Firestar reports at the Gathering that ThunderClan was doing well, and asks Leopardstar if she had news to share. She says that there was no news to share and that RiverClan was well, and Firestar told her he was happy to hear that.
- When Leafpool tells Firestar that she had a dream about RiverClan, he asks if ThunderClan was mentioned in it, but she said no. Firestar asks her if there was any clear sign of what RiverClan's problem was, but Leafpool said no. Firestar tells her and Jaypaw that if RiverClan needs help they can ask ThunderClan when they need it, instead of trying to help them.
- When Leafpool tried to get him to help, he gets angry at her, and tells her that Onestar has probably had enough of their meddling, and Blackstar is looking to get even with ThunderClan. He says that he's only made ThunderClan the resentment and jealousy of the other Clans. Firestar holds a meeting to give Millie her warrior name, but Millie declines, saying that she wants to keep her name. Firestar accepts it, although the Clan doesn't, and he tells them all that it shouldn't matter if they have a warrior name or not, but the fact that they are loyal to their Clan. Hollypaw says that Brambleclaw should've spoken out, but Squirrelflight tells her that Brambleclaw is the deputy, which means he should support Firestar since he is the Clan leader, and she reminds her that Firestar once was a kittypet.
- After Cinderpaw breaks her leg, Jaypaw tells Hollypaw to see Firestar because he must want to know what happened to Cinderpaw. A border patrol tells Firestar that WindClan almost crossed their border. Firestar tells them that if there is no scent of them across the border or any cats crossing over the border, then they should all just leave it alone.
- At the next Gathering, Firestar doesn't mention WindClan's thieving and ThunderClan thinks he's scared. When Hollypaw sees that something was wrong with RiverClan, she asks Firestar to send a patrol to check on the Clan, but he refuses. Millie refuses her warrior name when he tries to give her one. Later, Onestar accuses him of stealing Sedgekit, Thistlekit, and Swallowkit, not knowing that they were lost in the tunnels. He is relieved when the apprentices show up with the kits and stop the battle, thanking them deeply.
- In the beginning of the book, Firestar tells Lionpaw to rest since he worked hard all morning. He tells the border patrol to keep an eye out for WindClan, although things have been quiet since they found the missing kits. When Berrypaw tells everyone he passed his assessment, Brambleclaw says that it is up to Firestar to decide, and Firestar tells him that he'll gather the mentors and arrange the ceremony. Firestar gives Berrypaw, Hazelpaw and Mousepaw their warrior names, Berrynose, Hazeltail and Mousewhisker. Firestar goes on the evening patrol with Hollypaw and Brackenfur.
- When Berrynose and Birchfall are caught crossing over ShadowClan border, Firestar tells Russetfur that it was a mistake and will not happen again. As punishment, Firestar makes the two do apprentice duties.
- Firestar is later mentioned by Lionpaw when he is talking to Stormfur, where he says that he feels that he has to be better than all the other apprentices because he is Firestar's kin, and the other cats will expect him to be just as good as Firestar.
- When Firestar finds two cats from the Tribe of Rushing Water, he welcomes them kindly and asks them to come and stay as long as they need to. He listens to the cats' story, and says it would be fine for Stormfur and Brook to go.
- When Brambleclaw and Squirrelflight ask to go, he answers yes also, because those two cats know the Tribe better than any other cat, and the Tribe deserves help after what they did for the cats when they were journeying to the Lake. He also allows Jaypaw, Hollypaw, and Lionpaw to accompany the cats to the mountains.
- Firestar is seen padding down from the Highledge, along with Sandstorm. He gives Poppypaw and Honeypaw their warrior names, Poppyfrost and Honeyfern. He is also seen when he pulls Jaypaw out of the lake when he's trying to get his stick out of the water, then Firestar swims in to retrieve it himself. Firestar has some trouble with WindClan crossing the border. He tries to send some cats, but they are turned down by Ashfoot. Some cats want to fight, but he says no blood will be shed unless there has to be. When WindClan attack, Firestar fights against them. The ThunderClan leader directs his Clan into three patrols, himself leading one, to fight the three groups of WindClan. On his patrol, he finds the fox hole where WindClan was sneaking onto ThunderClan territory. He tells his warriors to cave in the hole, which started the fight by his patrol. At the end of the book, he gives two of his grandchildren and Cinderpaw their warrior names, hereby naming them Hollyleaf, Lionblaze, and Cinderheart.
- When Lionblaze is caught fighting with Ashfur for battle training, Firestar is angry about this and yells at them, telling Lionblaze that he is a warrior now, and doesn't need any more training, and that their fighting was much more violent than a regular practice session. He later becomes ill when greencough has spread around the camp. The catmint in ThunderClan territory dries out, so he leads the other cats that had caught the sickness to go into the old Twoleg nest. Firestar loses a life from the sickness; this is thought to have left him with five lives. When catmint is found, they all recover and the cured cats go back to camp. Millie and Briarkit are the last to recover from the greencough, but everyone returns to camp and gets back to normal. It is later revealed that Ashfur was the one that helped Hawkfrost try to kill Firestar, since he was the father of Squirrelflight.
- Firestar is worried that Sol might not be Ashfur's killer and starts to wonder if he was right to send the patrol to the sun-drown place. Later, he asks Leafpool if she can try to speak with Ashfur in StarClan and ask him who his killer was, but he is disappointed when she tells him that she can only speak to him if Ashfur comes to speak with her, and it isn't her choice about which StarClan cat to speak to. When Hollyleaf tells the Clans about their true parents, he is very surprised and shocked, but takes control over the Clan, saying that they need to stay strong, despite all that has happened.
In the Omen of the Stars Arc
- In one of Jayfeather's prospects in the early chapters, Firestar loses a life when a fox attacked him. Jayfeather fears that the ThunderClan leader has lost his last life, but is relieved when he opens his eyes.
- At the Gathering, Firestar reacts diplomatically to Leopardstar's claims that all the fish in the lake belong to RiverClan, saying that she wouldn't be able to do that, because she herself declared that the borders ended two tail-lengths from the shore. On the way home, he declares that ThunderClan will not attack any RiverClan cats patrolling the lake.
- When Rainstorm is brought into camp, he, (though reluctantly) rejects Thornclaw's idea about keeping the RiverClan warrior as prisoner for extra fresh-kill, despite knowing how much food they did need. He then allows Rainstorm to stay in camp to rest before he is taken back across the lake by a patrol.
- Lionblaze convinces Firestar to send a patrol upstream to see if something is blocking the water, working off of Dovepaw's keen senses. He tells Firestar and everyone else that she had a dream from StarClan. Firestar agrees, and at the next Gathering proposes the idea to the other Clan leaders and gets them to agree with him. The next day, he announces to his Clan that Lionblaze and Dovepaw will go to represent ThunderClan.
- He proudly welcomes the cats when they return, and briefly mourns the death of Rippletail when Lionblaze and Dovepaw report to him, but then is happy that they found the water.
- Firestar apparently is now experimenting with many new training methods, such as asking Lionblaze and Cinderheart to teach Dovepaw and Ivypaw about climbing trees and hopping between them, as well as having apprentices practice hunting as pairs, and warriors practicing battle together in teams.
- When Mistystar is on her way back from the Moonpool after receiving her nine lives, she stops to visit ThunderClan, and Firestar welcomes her as the new leader, as he is proud of Bluestar's daughter becoming leader.
- After Dovepaw tries, along with Ivypaw, to check on Sedgewhisker in WindClan, and is brought back to camp, Firestar lectures both of them about keeping to their own Clan's business, and then takes Dovepaw, Lionblaze and Jayfeather aside. He reveals to them that he knows that they are the Three of the prophecy, but that he doesn't know anything more about the prophecy than they do, to their disappointment. He soon meets with the Three every so often, and asks them to report anything strange they see to him.
- When ShadowClan scent is found on ThunderClan's side of the border, Firestar insists that they shouldn't make too much trouble over it, but says that he will mention it at the Gathering. When the Gathering comes, Blackstar says Firestar is falsely accusing ShadowClan, and that ThunderClan had been straying on ShadowClan's side of the border. He also declares that ThunderClan thought all the other Clans were indebted to them after the journey to find the water, when it had been an effort from all four Clans. Firestar and the rest of ThunderClan were angered by this, and tension escalates until the Gathering ends.
- When Jayfeather is in StarClan with Yellowfang, he sees five of Firestar's lost lives. Yellowfang says that the spirits cannot speak or hear now, but they will be able to once Firestar loses his final life.
- When Ivypaw approaches Firestar telling him that she has had a dream that ShadowClan will try to take more of ThunderClan's territory after Firestar gave them the Clearing, he is skeptical at first. She is persistent, and eventually persuades him to fight ShadowClan over the piece of land. Firestar brings his Clan to battle, and they fight fiercely. At one point, Firestar is fighting Russetfur, and although Lionblaze pulls her off of him and accidentally kills her, he is badly injured and loses a life: leaving only three left.
- Firestar is first seen being dragged away at the end of the battle between ThunderClan and ShadowClan, a trail of blood behind him. He is seen numerous times but does not usually have a major part in any of the times he appears. Later, Lionblaze talks to Firestar about chasing after the fox by himself. Firestar reluctantly agrees, but also states that he must take Dovepaw with him, in case he needs help, or for necessary self-defense. He later challenges Blackstar at a Gathering about his forcing ThunderClan to give him catmint by imprisoning Ivypaw just for crossing the border. With ShadowClan not giving any answers, ThunderClan are forced to fend for themselves and give away the catmint. Firestar does not seem too entertained by this.
- He tries out a new assessment technique, pairing a warrior with a mentor, then assessing how the apprentice works hunting with a partner instead of hunting alone. After hearing of Icecloud's accident, he makes an announcement on the Highledge. Firestar addresses the Clan by assuring them that Icecloud will be okay, and that a barrier must be made around the hole. He also states that he will take a look at the hole for himself. Then, he asks for a report on the assessment of the apprentices. He then gives Dovepaw and Ivypaw their warrior names, naming them Dovewing and Ivypool.
- At the Gathering, he is described in Dovewing's perspective to be well muscled and sleek furred. Then Jayfeather comes to him to tell him about going to the Tribe. He declines and then is persuaded into it. He lets Dovewing go, but not Lionblaze, saying if there was a battle Lionblaze would be their best shot. He also says to take Squirrelflight and Foxleap.
- Lionblaze mentions that it was Firestar's idea to go training in the nighttime, because Firestar wanted his Clan to have training in different ways.
- Firestar first appears as he is conversing with Brambleclaw, Thornclaw, and Brightheart He comments to Brambleclaw about the current peace between the Clans.
- After a fight almost breaks out between ThunderClan and WindClan patrols, Sorreltail frantically informs Firestar of the situation. Firestar calms the Clan and assures Birchfall and Ivypool, two of the cats who were involved, that they have not broken the warrior code. Not long after the incident with WindClan, Firestar decides that it is time for Cherrykit and Molekit to become apprentices, as there has been a shortage. When Molekit tries to object, saying that Firestar only wants him to do the "nasty jobs" the Clan leader only remains amused.
- Molepaw and Cherrypaw claim that a mysterious cat rescued them from a fox. Firestar ensures them that he will ask the other warriors if they have seen anything suspicious. At the Gathering, Onestar accuses Firestar of conspiring an attack on WindClan. Firestar furiously objects, asking whether or not Onestar or any of his warriors can identify the cats they supposedly saw on the border. Eventually, he wins the argument.
- Brambleclaw and Lionblaze discuss Onestar's outburst with Firestar. Lionblaze points out that WindClan might be right, reminding them of the cat Cherrypaw and Molepaw claimed to have seen. Firestar agrees and allows him to track down the intruder. When Sol returns, Firestar curtly allows him to stay the night. At first, the ThunderClan leader disapproved of Sol's sudden presence, but he feels required to let him stay once Poppyfrost and Berrynose thank Sol for saving their kits. It is clear that Firestar does not trust him.
- Brambleclaw claims that Sol is going to betray the Clan, though Firestar tries to calm him down, telling him they can't exile Sol from ThunderClan without proof of his wrongdoings or he will only cause trouble in other Clans.
- Hollyleaf returns, and Firestar welcomes her back into the Clan. Dovewing urgently informs him of their escape from the tunnels after hearing WindClan and Sol plotting an attack on ThunderClan.
- When Hollyleaf admits to killing Ashfur, Firestar refuses to punish her, even when the Clan disagrees. He says that although she should have spoken up sooner, living outside ThunderClan and her guilt of keeping the secret is enough punishment. When he finds out Cinderheart is Cinderpelt, he is, like most of the Clan, very shocked. Also, Cinderheart decides to be a medicine cat, and he accepts it but is shown to be disappointed, as Firestar likely wanted his former apprentice Cinderpelt to finally follow the path as a warrior.
- Firestar calls Dovewing in for a meeting. He asks her to cast her senses toward WindClan and figure out what is going on. When the reply is vague, Firestar seems somewhat puzzled. He tells Dovewing that Sol still has a score to settle with the Clans, but he doesn't know what it is.
- After Dawnpelt's outburst at a previous Gathering, Firestar temporarily bans Jayfeather from future Gatherings- just as the other Clans asked of him. He and the other leaders discuss the strange scents that have appeared inside each Clan's territory. The scents were mentioned to be 'not from the Clans'.
- Firestar follows Jayfeather out of ThunderClan camp, noticing that the medicine cat seems troubled. When Jayfeather scornfully makes a point that Leafpool broke both the warrior code and the medicine cat code, he is puzzled at Firestar's obvious surprise. Firestar honestly admits that he doesn't think about it, then tries to convince Jayfeather that it was meant to happen.
- Firestar appears when Blackstar comes with his warriors to ThunderClan about Lionblaze's trespassing, and Firestar promises him that no ThunderClan warrior will cross the border again, and he appears when he confronts Lionblaze about his destiny and tells him he doesn't have a choice, but afterwards, he appears troubled and says to his grandson that he can't force his destiny on him.
- As a continuation of the Fire alone will save the Clan prophecy, Firestar discovers that he is the fourth cat from the Tribe of Endless Hunting's prophecy in a dream when Jayfeather appears, the interpreted sign the fire in the reeds by RiverClan. He vows to StarClan and Jayfeather that he will unite the four Clans.
- Firestar meets with the other Clan leaders and their medicine cats to discuss the prophecy, informing them about Lionblaze, Jayfeather, and Dovewing's powers and about the Dark Forest cats' plan to overtake and destroy the Clans and warrior code. Once the leaders have heard everything he has to say, they agree to join the alliance to fight for the warrior code and their Clans.
- Despite Sandstorm's protests, Firestar insists on fighting in the final battle, waving off her protests of his last life by countering that every ThunderClan warrior besides him only has one life. He lines up with several other ThunderClan warriors, then scares away a couple of Dark Forest cats, and later guards the nursery. He then appears again at the end of the battle, fighting Tigerstar and successfully winning the fight. Although Firestar kills him, lightning strikes a tree and it catches fire, and smoke billows over him and he dies from all of the wounds he received during the battle. His spirit then leaves with Bluestar when she introduces the Three to the cats that gave Firestar his nine lives, sweeping his gaze over the Clan for the last time.
In the A Vision of Shadows Arc
- Jayfeather spots Firestar walking towards him and Leafpool when they go to the Moonpool at half-moon to share tongues with StarClan. A shiver passes through the medicine cat as he watches Leafpool cross the clearing to touch noses with her father. Jayfeather notices that there are strange cats watching them, and he demands to know who they are. Firestar mews a greeting to the medicine cat, and pointedly looks at the other StarClan cats. Leopardstar drily meows at him that he may as well speak for them all this time, and the ThunderClan leader explains that a time of great change is coming to the Clans. He tells the surrounding medicine cats that they must embrace what they find in the shadows, because only they can clear the sky. The silence stretches out for several heartbeats, and Jayfeather snarls, glaring at the ginger-pelted leader. He sarcastically questions if they could've tried any harder to make it more obscure. Firestar gazes at the medicine cat with a mixture of affection and irritation, and the StarClan cats fade.
- While Alderpaw takes the ticks off Graystripe's pelt, the gray elder comments that even Firestar had taken off countless ticks. When Bramblestar speaks to his son about his apprentice days, the apprentice mumbles that he knows Firestar was his mentor. Alderpaw states that he must've thought he was pretty great to mentor him as leader, but the ThunderClan leader mews that he thought Firestar wanted to keep an eye on him as Tigerstar's son. Bramblestar then tells his son of the first time his mentor took him hunting, he'd slammed into a tree by running so fast. The leader says the worst part was knowing that Firestar had to stop himself from laughing, and that comforts Alderpaw.
- He is later mentioned in the Gathering by Jayfeather who informs them of the prophecy. Therefore, resulting in Needlepaw commenting negatively of how he always gets involved in everything, even though he's dead. Cats in the Clans ask questions about StarClan's message, and Jayfeather answers that Firestar had said it was meant for all the Clans.
- His final appearance is in Alderpaw's dream, and the apprentice thinks that he feels at ease with him right away. Firestar meows for the young cat to follow him, and they stop near where a stream forms a pool. The ThunderClan leader instructs Alderpaw to look into the pool, and he sees a deep gorge with a warrior ceremony being performed. The apprentice asks who the cats are and where they live. Firestar dips his head to Alderpaw, but does not reply to any of his questions. A few days later, Bramblestar tells his son of the ThunderClan leader's travels to SkyClan with Sandstorm. The dark tabby says that they restored the Clan, and Alderpaw marvels at this.
- Later, he is mentioned in Alderpaw's dream by Sandstorm when the elder is said to be happy when she came to StarClan to reunite her mate. The medicine cat apprentice asks if she's seen him yet, and she replies yes. Sandstorm meows that she'd never wanted to live out her last days in camp, and was glad when his quest gave her a chance to relive a memory of Firestar. When Mistfeather hears that Alderpaw is from ThunderClan, he exclaims that he must know Firestar, the cat who saved his Clan. The former SkyClan cat tells him that he wasn't born when he came to the Clan, but notes that his story was told every full moon upon Skyrock, and was honored.
- After Sparkpelt's warrior ceremony, Graystripe comments that he'd been sure her name would've been Sparkfire. The gray elder says it would be a good way to remember Firestar, as Sparkpelt looks like the former leader.
- Firestar appears to the medicine cats as they visit the Moonpool every half-moon. After Leafpool asks that they've found SkyClan, and eagerly asks if they're what you find in the shadows, Firestar confirms so, but mentions that there is more to be done. He meows that not every Clan is present, and that this was about restoring the five Clans, as it was long ago, long before he came to the forest. He tells them that SkyClan has no medicine cat, and that another Clan is missing from the group as well, before fading.
- Later on, when the SkyClan ancestors are reuniting with the original StarClan, he appears again, padding into the middle of the clearing, beckoning to the medicine cats to join him. At his paws is a five-pointed leaf, and he asks the medicine cats if they know what it means. After the medicine cats take some guesses, and Alderheart gets it right, saying they need to claim ShadowClan's land back, Firestar nods, and adds that for them to do that, the Clans must remember their names. The former ThunderClan leader then fades, and does not appear again. But he is mentioned when Twigpaw thinks about how the Clans would attack the rogues.
In the Ravenpaw's Path Arc
- Firestar is seen once and briefly in the beginning of the book as Firepaw. He is seen with Ravenpaw and Graypaw while they are taking him to Barley's farm. He is not seen after that. It is also mentioned by Spottedleaf that Firestar would be able to help Ravenpaw and Barley in getting their farm back.
- Firestar is first seen when Ravenpaw and Barley come to ThunderClan, asking for a battle patrol to come back with them and help get their barn back. When Ravenpaw asks, Firestar dodges the question, instead making an attempt to make Ravenpaw and Barley more comfortable staying in ThunderClan. When a patrol is attacked, Firestar is forced to admit the trouble that they are having from the BloodClan rogues' living in the Twolegplace and is also forced to admit that ThunderClan couldn't spare a battle patrol at the time, but that after the problem is solved, he'll send a patrol to help Ravenpaw and Barley.
- When Ravenpaw and Barley return with Barley's sister, Violet, Firestar prepares to lead ThunderClan to attack BloodClan, he also tells his warriors to show no mercy, which is something he rarely would say. Once BloodClan is defeated and disbanded, Firestar informs Barley and Ravenpaw that ThunderClan will send a battle patrol and he would lead it himself.
- In this book, Firestar leads a patrol of ThunderClan cats to defeat the rogues who have taken over Barley and Ravenpaw's barn. At the barn, he gives out orders to set up a camp and hunt. After exploring the barn, Firestar tells the cats his plan to attack them. Later, at night, he leads the cats to the barn. When Snapper finds them, Firestar orders the patrol to attack. After the farmer yells at them to go, Firestar tells the ThunderClan patrol to meet up at the cowshed- their camp. Once they come up with another plan, Firestar and the patrol go to attack the rogues again. But when more rogues come, Firestar tells the cats to retreat and regroup. Firestar loses a life during the battle. After winning the fight, Firestar says goodbye and leaves.
In the The Lost Warrior Arc
- Graystripe thinks about his first encounter with Firestar, and comments that he knew that Firestar was a real warrior at heart. He also has a vision of Firestar and other ThunderClan cats calling to him while he travels to search for his Clan.
- Although he is not seen, when Millie scares off the dogs, Graystripe says, "I wouldn't be more surprised if Firestar floated out of the sky and licked me on the nose."
- Firestar is the first cat to recognize Graystripe and Millie at the Gathering. He and Graystripe are extremely happy to see each other. The book ends just as Graystripe is going to introduce Millie to Firestar.
In the SkyClan and the Stranger Arc
- He does not appear, but Leafstar wonders why he didn't tell her about parenting kits and Echosong says it's probably because he's a tom and he didn't have that kind of problem. Leafstar names one of her kits Firekit in honor of him.
- When Petalnose, Patchfoot, and Fallowfern tell Leafstar about their thoughts on leaving SkyClan, Petalnose reminds Leafstar about the rats that drove the first Clan out, and that she and Patchfoot later fought them again with Firestar and Sandstorm.
In the Field Guide Arc
- Firestar introduces the reader to ThunderClan and describes how he became a leader. He said that he would lay down all of his nine lives for his Clan, just like his Clanmates would give their lives up for him. Firestar says that there is no Clan in the forest truer or braver than ThunderClan. He describes his Clan as the Clan of heroes, compassion, and destiny.
- When Sandstorm shows the reader around the old ThunderClan camp, she tells the reader that Firestar asked her to show them around. She shows the reader Firestar's den and peeks around in it. Sandstorm thinks he must've left to go on a patrol, and she tells the reader that he sleeps beyond the lichen in his den. She says Firestar was a pudgy kittypet when she first met him, and that no one thought he would ever become leader. When Sandstorm talks to Leafpaw about Squirrelpaw, she tells her that she'll have a word with Firestar about letting her come to the Gathering.
- When Squirrelflight shows the readers around ThunderClan's new camp, she jumps onto the Highledge and tells the readers that Firestar makes his announcements from there. When she accidentally calls a meeting, Squirrelflight brings the reader to hide in Firestar's den. She tells the reader that Firestar sleeps in a bed of ferns and moss, and accidentally messes it up, and asks the reader if they think he'll notice.
- Firepaw is listed as one of Bluestar's apprentices.
- Firestar is listed as one of ThunderClan's significant leaders. He is described as brave, intelligent, loyal — a natural leader. It is said that he has an unusually strong connection with StarClan. It also says he brought WindClan back after being exiled by ShadowClan, and uncovered Tigerstar's treachery. It states that he saved the clan from a terrible fire in the camp, and discovered Tigerstar's plan with the dog pack. Finally, it says that Firestar led the clans in battle against BloodClan, and kept the clans together as they found their new home.
- Firestar is mentioned to have prophetic dreams, even when he was a kittypet.
- Firestar is said to have given his Clan little chance to forget Firestar's kittypet origins, by bringing Cloudtail to the clan and Daisy to the nursery. Rock explains to the kits how Firestar's kittypet origins do not make him less of a warrior, and he wonders what Bluestar was thinking when she brought him into the forest.
- Rock shows sympathy for Firestar, saying that he is hardly able to close his eyes without some kind of dream filling his mind, though admits that Firestar has handled this well. He wonders whether it took more than a Clanborn cat to discover Tigerstar's treachery, or bring WindClan back home when they were chased away by ShadowClan. He also says Sandstorm has forgiven Firestar for his kittypet roots. Rock wishes him nothing but peace, and a long life. Rock corrects himself, however, by saying that he knows how each and every one of Firestar's lives will be taken. Although saying this, he refuses to tell the kits how he dies.
- When Rock talks about Bluestar, Firestar is mentioned, if Bluestar took him over as her own kit, since she lost hers. He also said that Bluestar saw Firestar as a savior the moment the sun hit his flame-colored pelt. He says that Spottedleaf had said to Bluestar that Fire would save the Clan, so Firestar must have seemed like a gift from StarClan.
- When talking about Graystripe, Rock says Graystripe was the first cat to befriend Firestar, when he came into the forest. He also says that they both share the same foolish generosity. Rock says that Sandstorm won Firestar's heart after Spottedleaf died, and if it wasn't for her, Firestar might not have fought BloodClan at all. On Sandstorm's page, Rock says that Firestar had determination to save the forest from Scourge. Sandstorm made Firestar believe he was doing the right thing to fight the cats from Twolegplace. He says Firestar trusted her because she loved him above all, and would never sacrifice his life for the Clan. Rock says Sandstorm knows Firestar better than he realizes, better even than Spottedleaf and that Sandstorm isn't just his shadow either. Her courage had matched his on the journey to rebuild SkyClan, and matched Firestar blow for blow in the battle against the rats. He says he hopes Firestar appreciates her journey as much as she deserves.
- On Squirrelflight's page, Rock says that The Great Journey proved that she had the courage of her father, Firestar. When Rock talks about Cloudtail, he says that Cloudtail went back to his kittypet life, until StarClan and Firestar gave him a second chance by rescuing him.
- Rock tells the reader that Firestar has waited a long time for Jaypaw, Hollypaw, and Lionpaw, but in dread, not hope, because he wondered how any cat could posses more power than StarClan. When talking about Tallstar, Rock mentions that Tallstar had no choice to do anything when Firestar and Graystripe risked their lives to bring his Clan home. Also Tallstar trusted Firestar when he said that Bluestar was mistaken, and refused to fight ThunderClan.
- It was said on Onestar's page, that Onestar was good friends with Firestar the moment they met on the journey back from the Thunderpath. Firestar believed that they could depend on their friendship forever, and was only too pleased when Tallstar switched his deputy at the last minute. Rock says Onestar knew that the clans would call him Firestar's kittypet, and would roll over and let him tickle his belly whenever it suited the ThunderClan leader. It was a hard lesson for Firestar to not have his old friend, but it was even harder for Onestar because he missed Firestar.
- Firestar is mentioned twice on Leopardstar's page. Rock says that since Leopardstar saw Crookedstar's attitude towards half-Clan cats, she turned her back on Firestar and his Clan of kittypet warriors. He says that thanks to Firestar, she ended up on the winning Clan (LionClan) against the BloodClan cats. On Feathertail's page, Rock tells the reader that Firestar, Graystripe and Ravenpaw saved Feathertail, Mistyfoot, and Stormfur when TigerClan held them prisoner.
- Firestar is mentioned once when Rock talks about Hawkfrost. He says that it was Tigerstar's idea for Hawkfrost to plot with a ThunderClan enemy of Brambleclaw's to lure Firestar into a fox trap. Tigerstar underestimated Brambleclaw's loyalty to the Clan leader, so Brambleclaw killed Hawkfrost and saved Firestar instead. On Barley and Ravenpaw's page, Rock says that Firestar persuaded Ravenpaw to leave the forest and go live with Barley, or else Tigerstar would have killed him.
- On Smudge and Princess' page, Rock says that Smudge was Firestar's neighbor when he was a kittypet, and Smudge wondered why Rusty would've wanted to live with the Clans, but still stayed friends with him. He never forgot his friendship with Firestar, and allowed him to stay outside his Twoleg nest to dream of the SkyClan cats. Princess was Firestar's littermate who lived with different house folk. When she found out Firestar was the leader of a group forest cats, she gave her first born kit, Cloudkit, to Firestar to bring to the Clan who later becomes Cloudtail. Rock says Princess was a good friend of Firestar's and he says she still sits on her fence and looks out into the woods, wondering where he is and if he's safe.
- When Rock talked about Cloudstar and Skywatcher, Firestar is mentioned a few times. Rock says that if kittypets like Firestar can catch mice and thrushes, surely forest-born cats can pick up those skills? Cloudstar said to Birdflight that he would wait for her forever, but they didn't meet again until Firestar and Sandstorm rebuilt their Clan. Also, Rock said that when Firestar and Sandstorm arrived at the gorge, Skywatcher was the last descendant of SkyClan.
- On Leafdapple, Echosong and Sharpclaw's page, Rock says that Firestar invited Leafdapple into the new SkyClan because she could leap high into trees, showing her SkyClan ancestry. Rock told the reader that Echosong had a dream of Firestar and Sandstorm before they found the gorge, and knew that these cats needed her help.
- On Scourge and Bone's page, Rock says that Scourge killed Tigerstar and Firestar had to watch helplessly as Tigerstar lost all nine of his lives. In revenge, Firestar killed Scourge, losing one of his lives in the process.
- Firestar is mentioned in "Welcome to the Warrior Code" when Leafpool tells the reader that Firestar told her that they would be visiting that day.
- Firestar is featured as a young apprentice in Who Goes There? Whitestorm Teaches Border Tactics. He is still tormented by Sandpaw and Dustpaw, by Dustpaw trying to push him into brambles and Sandpaw preparing to put a fire ant in his pelt, but Whitestorm caught them every time. Whitestorm makes Firepaw go to the end of the line at first, and Sandpaw thinks he has fleas, to which her mentor denies.
- When Whitestorm asks what a patrol might smell besides their own Clan's borders on a border patrol, Firepaw answers, saying the other Clans' scent. Firepaw indicates the rest of his "patrol" when Whitestorm demonstrates to them what happens when other cats cross their border.
- In another part of the book, Sandstorm talks about her love for Firestar. She asks if Fireheart was just a kittypet, would he stop Bluestar from fighting with WindClan, would he had risked Bluestar's trust, or would so many of his Clanmates had supported him, even Whitestorm or Goldenflower. Sandstorm says that Dustpelt always told her that Fireheart can never be a true warrior because he wasn't born in ThunderClan. She states that he was a show-off when he first came to the Clan, always catching more prey, being the best in battle-training, or being the most solemn at Gatherings. She and Dustpelt could never figure out why Graystripe was friends with him because he didn't even seem to know what fun was. He always got into trouble, as Sandstorm said, like sneaking Ravenpaw out of camp, she saw him and Graystripe sneaking out of camp with Ravenpaw, then Fireheart came up with the excuse that Ravenpaw was killed. He always had annoyed Tigerclaw, she said, but now it looks like he was right, as Tigerclaw was the biggest enemy of ThunderClan.
- She says Fireheart didn't just accept the warrior code; he thinks about it and figures out how it's supposed to work. Dustpelt told her that Fireheart doesn't belong in ThunderClan because the warrior code says to reject kittypets, but she said that they have to reject that life, not the cats. Sandstorm says Fireheart would argue with any cat, in or out of ThunderClan, if he thought they were doing the wrong thing, and she said she doesn't want to live in a Clan that's always in war. She says Fireheart would stop a battle if it was unnecessary, and that's why Tallstar trusted him to make sure that ThunderClan and WindClan didn't fight. She told the reader that maybe a kittypet can know us better than we know ourselves, and maybe it takes an outsider to look into the truth, like Fireheart did with Tigerclaw. She wonders if he'll ever see the truth in her heart, however much Fireheart breaks the warrior code, she'll always love him more than any other cat. Finally, she asks that if he knew, would he love her back?
- Brambleclaw mentions to the reader that Firestar has started holding training sessions in the trees, so ThunderClan cats can learn to move among the trees and come down on the enemy from above. Buzzardstar also mentions how his former leader, Cloudstar, summoned Firestar to rebuild the old SkyClan, and Sparrowpaw excitedly tells Clovertail how Firestar related the famous sky-drop move to his sister's mentor, Sharpclaw.
- He is also fleetingly mentioned in Tigerstar's tales of battles in the old forest; when he fetched back WindClan with Graystripe, when he arranged a chain of cats to keep the dog pack away from the camp, and when Tigerstar admits that Firestar showed great courage with BloodClan, and states that he'll need every whisker of it when they meet again.
- The rogue, Nightwhisper, attempts to kill Firestar, who was then Fireheart, when Tigerclaw led his rogues on the ThunderClan camp. Fireheart fights back and gets away with Brackenfur's help.
- Later, Graystripe relates a battle with the foxes, and mentions how Firestar and Sandstorm were away somewhere on a special mission.
- On Bluestar's page, he is mentioned briefly to have been the leader after Bluestar, and that he had been the fire Bluestar had been searching for.
- Firestar next appears on his own page.
- Firestar used to be a kittypet, Rusty. He had great interest in the forest, the home of the Clan cats, similar to that of Jake. He later met Graypaw and Bluestar, who linked him to the prophecy: "Fire alone will save the Clan." It wasn't long before he became deputy after many moons of training. But Firestar was still accompanied by his rivalry with his enemy, Tigerclaw, whom had been banished from ThunderClan by Bluestar after Fireheart told the Clan of his treachery. He became close friends with Graypaw, Ravenpaw, and Spottedleaf. Following Spottedleaf's death, Firestar fell in love with Sandstorm, who had his kits, Leafkit and Squirrelkit, shortly after he became leader. He led the four Clans away from the forest to the lake when Twolegs began destroying it to make way for a new Thunderpath, with the guidance of StarClan. Firestar used his nine lives wisely, and lost each with his desire to protect ThunderClan, the most important one being his final life, which he lost to Tigerstar in the battle with the Dark Forest. Lightning signified his arrival to StarClan.
- Firestar is brought up next on Spottedleaf's page as her former love interest. She never lost her faith in him, and watched over him until she lost her final life in the act of protecting Sandstorm during the battle with the Dark Forest. Firestar is mentioned on Graystripe's and Millie's page. He is said to have met Graypaw first, and had hunted prey to feed RiverClan with Graystripe. It is mentioned that it hurt Graystripe to leave him behind when he left to go to RiverClan after his mate, Silverstream's death.
- Firestar appears on Sandstorm's page often. It is said that she and Dustpaw had tormented him as apprentices, but she and Firestar later fell in love. When Firestar wanted to drive BloodClan out of the forest, Sandstorm encouraged him to do so. She was equally matched with Firestar in many aspects, and had mothered Leafpool and Squirrelflight well. Though she would not have minded having more kits, she was aware that the Clan's demands pressured Firestar enough. He is mentioned twice on Brightheart's and Cloudtail's page. Cloudtail was the son of Firestar's kittypet sister, Princess. Cloudpaw struggled in the clan at first and returned to kittypet life until StarClan and Fireheart gave him a second chance.
- On Yellowfang's page, he is mentioned to have been the one to find her on a patrol by himself. He had to care for her as punishment after breaking the warrior code. The two became close over the course of time. On Cinderpelt's page, it is mentioned that Cinderpelt was Fireheart's first apprentice. It is also mentioned on Squirrelflight’s page that she demonstrated the courage of her father.
- He is mentioned twice on Brambleclaw’s page. The fact Firestar didn’t hesitate to trust Brambleclaw sent a clear signal to his clanmates that Brambleclaw should not be judged for Tigerstar’s actions. At last moment with the possibility of losing Firestar, Brambleclaw realized where his loyalties truly lay. It is mentioned on Ashfur’s page that although Ashfur may have not been close friends to Firestar, that didn’t stop him from being trustworthy, loyal to his Clan and a valuable warrior in the thick of battle.
- He later appears on Lionblaze's page. It is said that he had obtained the prophecy, "There will be three, kin of your kin, who hold the power of the stars in their paws," from Skywatcher. Once Lionblaze and his sister, Hollyleaf, and his brother, Jayfeather arrived, he knew they were the cats Skywatcher spoke of. It is mentioned on Hollyleaf’s page that Hollyleaf saw no point in telling Firestar about her accidentally killing Ashfur. He is mentioned twice on Dovewing’s page. Dovewing is kin to Firestar through her mother’s father, Cloudtail. Dovepaw turned out to have extra special senses, and Jayfeather told her to pretend that she saw the beavers in a dream, which Firestar would understand. It is also mentioned on Briarlight’s page that Firestar ordered an evacuation of ThunderClan camp when a loose-rooted beech tree started falling into the hollow.
- Firestar appears during Brambleclaw's leader ceremony.
- He greets Brambleclaw upon his arrival, and tells him not to grieve any longer. After telling him that he had been happy with ThunderClan and that he appreciated Brambleclaw's role as his former deputy, Firestar touches his muzzle to Brambleclaw's head and gives him his first life, the life with the courage to make the hardest decisions. After Brambleclaw receives his other lives, Firestar welcomes him as the new leader of ThunderClan, Bramblestar. Brambleclaw says he would be proud if he could lead the Clan as well as Firestar, and he responds by telling him to go, and that he'd always be with him.
- On Tigerstar's page, it is said that he had wanted revenge on Firestar, and trained his sons, Brambleclaw and Hawkfrost, to kill him. Later on, he had his final battle with Firestar, but died in the process, with Firestar following shortly after.
- On Tallstar's page, Tallstar is mentioned to have known Firestar was Jake's son ever since he first arrived to the forest, and that he held him in high esteem. He also appears on Onestar's page. Onewhisker befriended Fireheart and the young warrior brought WindClan home after being driven out by Brokenstar. Their friendship helped both clans as Onewhisker helped Fireheart persuade Tallstar not to attack ThunderClan, but when Onestar was made leader, this friendship was made a burden. Onestar was made to fight alongside Firestar once again when the Dark Forest rose to destroy the Clans. Firestar is mentioned to have come Onestar's help when Mudclaw started a rebellion. On Feathertail's page, Firestar is mentioned to have rescued Featherpaw and Stormpaw with Graystripe and Ravenpaw.
- Firestar appears once again on Hawkfrost's page, who is said to have gotten Ashfur to send Firestar down to the lake in order to send him into a trap. Brambleclaw refused to kill Firestar, and instead killed his brother and rescued his leader, fulfilling the prophecy: "Before all is peaceful, blood will spill blood and the lake will run red."
- He appears on SkyClan’s introductory page. Firestar was sent by Bluestar to rebuild the Clan, tracking down descendants and inviting cats to hold the warrior code, eventually working together to defeat the rats. On the page shared between Cloudstar and Skywatcher, he is said to have rebuilt SkyClan with Sandstorm, and that Skywatcher had been chosen to deliver the prophecy to him: "There will be three, kin of your kin, who hold the power of the stars in their paws."
- Firestar also appears on Leafstar’s page. Leaf was a loner in the woods when Firestar first approached her and told her about SkyClan, his tales of StarClan and how cats work together to survive drew Leaf in. With the warrior name of Leafdapple, she learned fast. A vision of dappled leaves made Firestar realize that this is a sign that Leafdapple will be the new leader.
- It is mentioned Stormfur's and Brook's page that Firestar invited them to his Clan after they were driven out of RiverClan. Firestar is mentioned twice on Echosong’s page. She was expecting Firestar and Sandstorm when they came looking for new warriors in the Twolegplace. Firestar knew that with Leafstar and Echosong, he was leaving SkyClan in the safest paws. It is also mentioned on Sharpclaw’s page that Firestar only needed a chance encounter to realize that Scratch had the SkyClan ability to jump.
- He is mentioned on Ravenpaw's and Barley's page. Firepaw saved Ravenpaw from Tigerclaw by taking him far from the forest and to the farm where Barley lived. Firestar is last mentioned on Smudge's and Princess' page. Smudge had been a loyal friend to him despite his disapproval of his obsession with the forest. He had the same dreams from Cloudstar as Firestar had. Princess was Firestar's sister. She gave him her firstborn kit, Cloudkit, to live in his Clan. They both frequently thought of one another.
- Firestar is also mentioned on Scourge's and Bone's page. Scourge is Firestar's half-brother. In a ferocious battle, Scouge struck Firestar with the first deadly blow, but Firestar has been given nine lives by StarClan and recovered to strike back. Scourge died at Firestar's paws. He is mentioned twice on Sol's page. Leafpool saw no importance in Sol's warning of darkness, so Firestar sent him away. When Sol is taken back to ThunderClan to answer for Ashfur's murder, the other Clan leader were furious that Firestar brought the troublesome cat back. He is last mentioned on Rock's page. Rock watched as the prophecy of the three, and Firestar, came true.
In the Short Stories and Plays
- Brightheart watches Firestar while he sleeps after being caught in a fox trap. His neck is bruised, and he is not able to eat or speak.
- Firestar appears at the first Gathering. He is reluctant to reveal that ThunderClan has plenty of prey during leaf-bare whilst the rest of the Clans are starving, in case they try to steal prey from ThunderClan's territory. When he doesn't talk much, Blackstar asks if he is too scared to admit that his Clan is going hungry, when it is really the opposite.
- When the elders - Halftail, Patchpelt, Dappletail, and Smallear - talk about the late appointment of Firestar (then Fireheart) as the new deputy. Patchpelt, Dappletail, and Smallear believe it is a sign that ThunderClan is breaking up, since the naming ceremony is late and Fireheart is a former kittypet. Patchpelt assures the elders that Fireheart isn't the rightful deputy, and Dappletail and Smallear agree. Halftail watches in dismay as they give up faith in Bluestar and Fireheart.
- Firestar first finds two injured RiverClan warriors, Pouncetail and Otterheart, on his territory, coming from the ShadowClan border. He takes them back to his camp to be nursed by Leafpool.
- Later, he calls a special Gathering before the full moon to discuss the troubles among the Clans: scarce prey, fighting along the borders, and the like. When the Clans decide they need to unite for a short time to survive, after the casting of stones as suggested by Jayfeather, he is elected as the leader for the united Clans for that time.
In the Novellas
- Fireheart is mentioned in the start, growling defiance at the defeated Tigerclaw as he is being exiled from his Clan, Tigerclaw silently scorns the young warrior as he smells the fear scent off of him.
- Later on when Tigerclaw attacks Mousefur's patrol, he is attacked by Fireheart. Tigerclaw tries to defeat the ThunderClan deputy, but he was losing strength. Tigerclaw finally flees along with his battlemates.
- When the fire strikes ThunderClan, Fireheart and Yellowfang volunteer to go back and save the elders and Bramblekit. Tigerclaw disbelievingly wonders if the life of his son depended on an elderly medicine cat and a kittypet, and follows Fireheart.
- Tigerclaw soon hears Bramblekit's screams, and he runs over to the noise, but Fireheart beats Tigerclaw to it and leaps up the tree. Tigerclaw is terrified for his kit, but Fireheart successfully saves Bramblekit. Tigerclaw then glowers at the deputy, vowing to kill him even though he saved his son.
- When Leafpool enters Firestar's den, she recalls how she had found him with a Twoleg trap around his neck. Hawkfrost had tried to kill Firestar by luring the ThunderClan leader into a fox trap. Brambleclaw rescued him by digging up the stake holding the trap, and then he killed his half-brother, fulfilling the Blood will spill blood prophecy. Firestar's wound resulting from the trap is shallow and will quickly heal. Leafpool brings her father honey to soothe his throat, and a poppy seed to help him rest. He insists that she must not fuss over him, but she reminds him that he lost a life yesterday. Eventually, he obeys and consumes the honey and poppy seed.
- Soon after, he is mentioned when Leafpool orders Whitepaw to retrieve more moss for Firestar's nest because it is frosty. His name also comes up when Leafpool asks Brackenfur if he thinks the leader made the right decision by declaring Graystripe dead and appointing Brambleclaw as the new deputy. Some cats also show concern for him after the accident, such as Cinderkit.
- Later, Leafpool asks her father for permission to visit the Moonpool, and he allows her to go after he promises her to stay in his den for the rest of the day.
- When Leafpool decides that she will leave the Clan to have her kits, she has trouble convincing Firestar. She lies to him, saying that when she visited the Moonpool, StarClan told her she needed to fetch a special herb that grows far away from the Clans. Squirrelflight bursts into the den and announces that she is coming with her sister, and Firestar lets Leafpool go, as long as she travels with Squirrelflight.
- He is mentioned by Hollyleaf, when Fallen Leaves asks if she remembers what happens when her and her siblings, Lionblaze and Jayfeather, went to rescue the missing WindClan kits. Hollyleaf remembers while her, her littermates and two other WindClan cats, Heathertail and Breezepelt, were looking for the WindClan kits, he and Onestar, WindClan's leader, were about to wage war on one another.
- Firestar is also mentioned very briefly multiple other times throughout the book, when Hollyleaf is recalling her time in ThunderClan.
- Mistystar remembers Firestar saving Featherpaw, Stormpaw, and herself from BloodClan.
- When Mistystar visits ThunderClan's camp to announce the death of Leopardstar and her own ascension to leader of RiverClan, Firestar speaks to her briefly, and Mistystar notes that he becomes more relaxed, like he was back when he was a warrior. Mistystar confides in him that three of her elders had passed away and Firestar is sympathetic to her loss.
- The Battle Against the Dark Forest is over, but Firestar has died during that battle. His body still lies at the foot of a lightning-struck tree, where Sandstorm grieves over it. Bumblestripe and Graystripe soon sit to grieve for Firestar too. After the vigil, his body is carried by Sandstorm, Graystripe, Squirrelflight and Millie. Millie murmurs to his body that they were born kittypets, and to look at them now. She calls Firestar a precious friend. Before the burial, Squirrelflight touches her paw to his cheek and wishes him to sleep well. The Clans bury all of the fallen with a proper send off.
- Purdy later remembers when Firestar once moved sick cats to the Twoleg den, to keep the rest of the Clan from becoming sick. Purdy comments it was a brave action and Sandstorm mentions that it cost him a life too. When Dovewing, Jayfeather and Lionblaze dream at the Moonpool, Firestar appears in front of them briefly, his eyes shining with love. Dovewing says his name, but the vision is gone immediately after.
- Firestar is not alive nor mentioned during this book, but Goosefeather does receive Firestar's prophecy of "Fire Alone Can Save Our Clan"
- Coming Soon
- He may be based on a cat Kate knew.
- The Erins believed that after the first arc, Firestar's story was pretty much over, so they started the next arc from a fresh viewpoint.
- Firestar's love relationship with Spottedleaf was never shown that often when she was alive because he was only a new apprentice at the time. Their relationship wouldn't have gotten much farther due to the fact medicine cats can't have mates.
- Firestar's mother, Nutmeg, probably does not know about him becoming a wild cat.
- The Erins confirmed that he has never had feelings for Cinderpelt.
- He is not related to the ThunderClan founder, Thunderstar.
- In an Erin Hunter Chat, it is revealed that Scourge and Firestar share the same father, Jake, and Firestar is noted to look exactly like him.
- In the same chat, it is also revealed that he loses a life helping Ravenpaw and Barley.
- One of Leafstar's kits, Firefern, is named after him.
- Kate stated that Firestar was not killed by the burning tree, but instead died of his wounds from the battle. Dovewing only imagined she saw him get up and walk away, and the lightning striking the tree snapped her back into reality.
- In response to a question about why Firestar wasn't just killed by Tigerstar, Kate Cary stated that they couldn't let Firestar be killed by the evil, but that it was essential for him to die due to "destiny and stuff".
- Although Firestar is confirmed to be on both the cover of Into the Wild and The Last Hope, his design changed on the latter cover with additional white markings and stripes.
- If Kate could give him a human name, she would name him Colin.

- Tigerstar was mistakenly called Firestar once in Eclipse.
- He has been mistakenly depicted with amber eyes on several occasions, and is said to have amber eyes in Dark River.
- He is mentioned to have seven lives despite only having five at the time.[source?]
- Fireheart was said to be the deputy after Lionheart died in The Elders' Concern , even though Tigerclaw became deputy after Lionheart.
- He has been mistakenly described as dark red, golden, and shown as a ginger non-tabby on the cover of Into the Wild, and in the manga of Bluestar's Prophecy, Yellowfang's Secret, and Tallstar's Revenge.

- "It was obvious to me that Firestar was Jake's son the moment I laid eyes on him. The bold young kittypet with the flame-colored pelt and the leaf-green eyes ... he was Jake's spitting image.
