First appeared in Incredible Hulk #271 in 1982 and was created by Bill Mantlo and Sal Buscema. Blackjack O'Hare was a Halfworlder mercenary and an anthropomorphic hare.
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.)
