Wendell is a demon. He is the brother of Wild. The two brothers are trapped in an underworld prison, sentenced to live atop the scalp of the dark and terrible lord of the underworld, Buffalo Belzer, who is also their father. They take on their arch-nemesis, the nun Sister Helley. Wendell is a tall purple demon with floppy pointed ears on the sides of his head, a small back top hat, a small beard at his chin, a long purple demon tail and small purple wings.
