Richard Corben

His best known property is Den, a fantasy series about the adventures of a young underweight nerd who travels to the other world of Neverwhere, a kind of adolescent version of Peter Pan's Never Land. There, the boy becomes a naked muscleman who has erotic adventures in a world of outrageous dangers, hideous monsters and buxom naked women who lustfully throw themselves at him. This story was adapted in a highly abbreviated form in the film, Heavy Metal
