Beelzebub is the Avatar of Gluttony and is the 6th oldest among the seven demon brothers. Beelzebub has messy orange hair and violet eyes with a pink gradient like his twin, Belphegor. He's the tallest of all the brothers, and extremely muscular despite his everlasting tendency to eat. This physique is owed to his other favorite pastime, working out. Like all the brothers, he wears nail polish, his being orange. He is also the most innocent brother.
