The Mutant Octopus is a common Earth octopus, which was mutated by Dr. Animo in the episode Divided We Stand.
He's main use was to attack people and defend Dr. Animo's base.
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.)
