Rattlesnake Jake is the secondary antagonist of Nickelodeon's 23rd feature film Rango. As his name implies, he is a dangerous Western diamondback rattlesnake who never leaves the town of Dirt without taking a single soul.
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.)
