Vesuvius is a fallen angel who appears in Disgaea: Afternoon of Darkness and Disgaea DS. According to the official website, he is a archangel who guarded the gates of Celestia for over 1000 years. Because of his strength, other angels feared him, and he was exiled. Overwhelmed by his pessimism, he lost his persona. Now he wanders around the Netherworlds living only for battle. He is fought at a certain point in the Cave of Ordeal's Demonhall Mirror. What truly makes him stand out from other opponents there is his equipped weapon, the rank 40 axe Apocalypse.
