Adam is an angel with a human appearance, usually wearing a mask with golden facial expressions and long, smooth horns tipped with gold. Beneath the mask, he has fair skin, golden-yellow eyes with dark bags, a stubbled chin, and messy cedar-brown hair. Large golden wings sprout from his back. As the leader of the Exorcist army, he exudes extreme egotism and unsympathetic cruelty, believing himself the perfect man and the origin of all male bloodline. He takes his role seriously, issuing threats and punishing disobedience without mercy, as he did to Vaggie for refusing to kill a Sinner. His narcissism is so profound that even in defeat, he refuses to acknowledge his fall.
