Actually, I'm pretty sure my mutant power is my tendency to sustain minor injuries on a constant basis. My codename is going to be "Injura".

It might sound like an impractical ability, but I'm thinking it will help protect me from *major* injuries in battle - like, I'd turn my ankle and fall over, thus avoiding a swing from a blade that would've taken off my head. Or I could trip and collide with villains, knocking them off a cliff.
