Obliterator

The Chaos Obliterator is a virally corrupted once-human cyborg who is able to absorb any weapon they hold for too long. These unfortunates can spawn these weapons from their very flesh, and also grow ammo for them. He is fused to his armor, and he is quite mad, possibly from the trauma of absorbing his weapons or being welded to his armor or the machine spirits of his weapons and armor fusing into a destructive daemonic entity.

Video games
