One Piece Odyssee

Magellan is a large man, about three times the height of a normal human. He has a face that resembles a mandrill, with very sharp teeth and a thick beard. His fingers closely resemble those of the Blue Gorillas. He wears bat wings and horn-like ornaments on his head, the latter of which he can pull out and use as weapons. Underneath those horns, he has short black twintail-styled hair. Overall, Magellan resembles a devil. While most guards wear a white-colored uniform, Magellan wears a black-colored suit with a red shirt underneath. His suit features more buttons than those of his subordinates. Draped over his right shoulder is a piece of rope. He wears what appears to be the standard cap of Impel Down workers

Though he only performs roughly four hours of duty per day as Warden of Impel Down, he still takes his role quite seriously and does not tolerate the prisoners' bad behavior

He is the head warden of Impel Down
