He was originally a cameo character appearing in the first and second seasons of Futurama. He was merely used as an Easter egg in crowd scenes, and was slowly forgotten, having not appeared in the third and fourth seasons. However, he re-appeared in the movies "Bender's Big Score" and "Into the Wild Green Yonder", and in the sixth and seventh seasons.
He is the leader of Legion of Mad Fellows and apparently a hobo.
He is voiced by David Herman.
