Walt is the secondary antagonist in the animated film, The Adventures of the American Rabbit. He is a mysterious, obese figure with a new black fedora and a pinstripe gangster suit. His face is completely hidden behind his white shirt, a purple tie, and a pair of sunglasses, the lenses of which flash yellow when he speaks. He has a pet vulture named Vultor. His minions are the Jackals. He was killed when the American Rabbit ripped off his sunglasses, deflating his whole body.
He was voiced by Kenneth Mars.
