Rock is a brown tabby tom with amber eyes, long, bloody claws, and many battle scars.
Rock was born a kittypet. He was very nice and kind until he was captured by members of Squeak's Group. They forced Rock to join and he slowly lost his sanity. He is now cruel, sadistic, and insane. He is one of the leaders of The Bandits. He is second in command alongside Dune and the cat incharge of teh group is Scratch.
