|"Not like this one, he is as large as a horse. He has tusks as thick as sycamore branches and a fleece of black hair as sharp as thorns. He killed one of our apprentices."|

Rage is a giant, male wild boar with thick tusks and black fur.
In the Field Guide Arc
- In the Great Clan myth, "How LeopardClan Won the River", there were many wild boars running in the forest, one of them being Rage, but Rage however is much more vicious and large, with huge tusks, as thick as sycamore branches, and a fleece of black hair as sharp as thorns. He was also mentioned to have killed one of the apprentices of the Clan of lions, LionClan.
- Fleetfoot, a LeopardClan warrior, agrees to kill Rage in exchange for LionClan's claim to the river for one moon. Fleetfoot follows the boar's scent trail until she finds it. Rage is under a tree, nosing at the ground. She charges him, frightening the boar away, and chases him as he runs. Rage runs so fast that, when he gets to the gorge, he cannot stop himself, and flies over the edge. The LeopardClan warrior jumps into the river after him, and pins him underwater, drowning him.
- Fleetfoot is washed up on the shore of the river, cold and tired. But, Fury, Rage's mate, attacks an already exhausted Fleetfoot. The two fight for three days, but in the end, Fleetfoot chases Fury onto the stepping stones, where Furu loses her footing thus falling into the river meeting her death.
- "She leaped at him with a ferocious yowl, and the boar, started, turned and ran."
