He is an embodiment of chaos and claims to be "completely evil". He is first shown exiting the Nightosphere as a mass of tentacles, eyeballs, intestines, and various other like appendages, but his usual form consists of a demon-like humanoid, he sports a white tank-top, a pair of green-stripped pink boxers, and has a slightly bulging belly that is hidden when he is wearing a suit. He has a good relationship with peppermint butler, and Marceline...who he tries to apologize to for eating her fries
