Abaddon serves as a high-ranking demon lieutenant under Lucifer in the anime, enforcing his master’s ambitions to sway power dynamics in the demon realm, though his personal motivations and precise maneuvers remain undefined. The manga diverges sharply, casting him among the Devil Army’s insurgent faction before he turns traitor, a betrayal swiftly punished by Fenrir, Lucifer’s ally. This act fractures the rebel forces, escalating internal tensions—a pivotal conflict omitted from the anime. While his allegiance shifts between loyal enforcer and opportunistic defector across adaptations, his enduring link to Lucifer remains central, anchoring his dual portrayal as a steadfast subordinate in one narrative and a catalyst for discord in the other.
