White-haired anti-heroes from two series created by Hideki Kamiya. Both are family members of the main characters, with Vergil being Dante's twin brother, and Balder being Bayonetta's father's past self. In the beginning, they start out on opposite sides with the main hero, and fight them repeatedly throughout the game. They spend most of the game working with the main antagonist, Arkham and Loptr respectively, until they betray and defeat them alongside the main heroes. However, in the end, they're corrupted by an outside influence and end up turning to the dark side once again. Both possess half of a powerful artifact, which the main characters possess another half of, with Vergil and Dante both possessing half of Sparda's amulet, and Bayonetta and Balder both possessing one of the Eyes of the World. They both are seen as mirrors to the main characters, due to possessing similar abilities and fighting styles to them, inclduing special transformations that unleash their full powers, Devil Trigger and Lumen Climax respectively. Finally, while Vergil is a half-demon and fights using demonic powers and weapons, Balder is a Lumen Sage that fights using angelic powers and summons.
