Blu is the main protagonist of Rio, Rio 2, Angry Birds Rio, other video games, and all of the books of the franchise (with the exception of Rio No.3: A Dog's Tale, where he is only a minor character). The human protagonist is Linda Gunderson.
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.)
