Flea (a.k.a. "P.T." or "Mr. Flea") is a character in Disney/Pixar's 1998 film, A Bug's Life. He is a greenish-brown flea who serves as a minor antagonist, but in the end he reforms.
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.)
