Beelzebub, armed with his Chaos Link
Beelzebub is one of the original Seven Princes of Hell and a central Antagonist in the series. He is arguably Sadow's most crafty and creative opponent, manipulating so many throughout history to further his own gain until he can create the Destiny Mirror.
Appearance
He is often seen in the human appearance of a rather medium-sized man with a slim build, green hair, yellow eyes that eerily remain closed most of the time, and wearing a black suit and fedora.
