Argosax

The demon king of Vie de Marli's legends, final boss of Devil May Cry 2.

Argosax the Chaos is the overarching antagonist of Devil May Cry 2, a demon king who once ruled the Demon World and subdued its demons before Sparda defeated him. On the island of Vie de Marli, whose guardians remember him as the most wicked of the demons their ancestors worshipped, Lucia's mother Matier had exorcised him centuries earlier with Sparda's help. The businessman Arius plans to summon Argosax with holy relics called Arcanas and absorb his power to transcend mortality; when a portal to the demon world opens, Dante passes through it and defeats the partially summoned Argosax.
