Gavel. I don't get really mad, shoot people down or make them look stupid, break or make a mess of things on purpose, have wolverine's or the juggernaut's mutant powers, feel better when I hurt others, like to make big waves or make people feel sick. I believe the best is yet to come, so I wouldn't ever turn back time, and I am certainly not untouchable.
I find it hard to do anything without gravity, and am most effective when standing on solid ground but am pretty adaptable in a pinch. My solutions usually involve more force than finesse (And all my best friends are golems!)
