Dory is the deuteragonist in Disney/Pixar's 2003 animated film Finding Nemo and the titular protagonist in its 2016 sequel. She is a regal blue tang who suffers from short-term memory-loss and is a bit ditzy.
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.)
