Name: Lord Crimson
Power: Blood manipulation. Can make the insides of any individual explode upon command if I concentrate. In the heat of battle where such executions are impossible, I change my internal blood composition to make me stronger and faster.
Costume: Dark red cape, black lightweight body armor.
Backstory: I'm a child of rape who grew up alone in Toronto's streets in the gangs. Discovered mutant powers at age 16. Joined Magneto's army young, took training with his forces but was locked up. Years later I escaped, built up a criminal network across the Eastern coast of Canada and the U.S.A. I employ hired goons and loyal mutant minions, rarely gracing anyone with my presence.
Motivation: Gaining enough power to resume Magneto's war.
