Make him Scruffy, but with superhuman strength! Was he a body builder, or is it just magic? Who knows. The idea of Scruffy throwing fireballs is kinda weird.
Little disclaimer, I have no idea what Scruffy is like, 'cause I have never watched Futurama. But I mean, he [i]seems[/i] slightly biased. The kind of guy that would mumble something not so nice about a group of people. Maybe out version of Scruffy could have this general distaste and distrust for anything or anyone magical.
