Injurin' Joe is the main antagonist of the 2000 direct-to-video animated musical film Tom Sawyer. He is a massive grizzly bear who is the animal version of Injun Joe, as well Tom Sawyer's arch-nemesis.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
