Beelzebub takes the form of a tall man with unkempt messy hair and deep black eyes. Beelzebub is shown to be a very calm and collected yet cunning and apathetic individual as he would treat other beings as experiments without any remorse or guilt. He also seems to be quite erudite. He's a creepy guy that does not have many friends. This is because of the curse he got when he was born, as a result all the gods fear and hate him and Beelzebub has been isolated from everyone.
