Reedwhisker/Main article

Reedwhisker is a slender black tom with small, neat ears and dark gray or blue eyes.

He is born to Mistyfoot and Blackclaw, along with his siblings, Perchkit, Pikepaw and Primrosepaw. When he is a young kit, a flood sweeps through RiverClan territory, and he is saved by Graystripe and Fireheart, leaving the young kit indebted to the two older cats. He later becomes an apprentice with the name of Reedpaw, and after nearly drowning in the river, he is saved by Leafpaw. He then becomes a warrior with the name of Reedwhisker, and gains his first apprentice, Ripplepaw, and later, Pouncepaw.

He becomes a senior warrior, and is given his third apprentice of Hollowpaw, and when Mistyfoot becomes RiverClan's leader, she chooses Reedwhisker to be her deputy. The majority of RiverClan supports her decision. He and Mistystar share a close bond during this time, due to Reedwhisker being Mistystar's sole surviving kit. Reedwhisker later participates in the Great Battle and lives to tell the tale. He then is given his fourth apprentice, Lizardpaw. He serves as deputy for many moons.

When the Kin comes and attacks RiverClan, Reedwhisker fights bravely, even going one-on-one with Darktail to protect Mistystar, but RiverClan loses the battle. He is severely injured and taken prisoner along with Mintfur, Icewing, and Brackenpelt. Reedwhisker shows open defiance and hatred of Darktail, and manages to escape with his fellow prisoners with the help of the other Clans, where he helps drive out the Kin once and for all. He helps Mistystar rebuild RiverClan and recover from the devastation caused by the Kin.
