Icewhisker is a silver-gray tom.
In the Super Edition Arc
- Icewhisker is an ancient RiverClan medicine cat under the leadership of Birchstar, during the time SkyClan is forced out of their territory by Twolegs.
In the Novellas
- Although he is not referred to by name, during a Gathering, when the Clans linger a bit to speak with friends from other Clans, Fawnstep pulls Cloudstar, the SkyClan leader, aside, and tells him that the other medicine cats, including Icewhisker, have had dreams of SkyClan being swallowed up by yellow monsters and trampled easily underneath fallen trees.
