I would be called "Protagonist," and my superpower would be that thing that main characters in action movies have where they've got magic super reflexes and are inhumanly good at everything humanly possible but don't really have any clearly defined "super powers." The best thing about this power is that I would always get out of every single bad situation I'm put into and accomplish any goal I want to accomplish, even if it's just barely.
So let's say hypothetically I suavely robbed a casino or something, and in addition to all the police showing up, all of you came after me at once with your superpowers. Somehow, I would win. You would fuck me up a little, maybe make my head bleed down to slightly under my eye, but ultimately I would pull some insane over the top bullshit that would deem me the victor and leave everyone else going "Aww no fucking way!"
