What I'd do, or what I want to do with it right now?
Since, god, forever, I've had daydreams of super-heroism. Sure, having powers would be fun on its own, but imagine all the people you could help!
But history tells of too many would be heroes, all possessing varying degrees of power- military power, political power- and all being corrupted by it. Not really sure if I'm any better than they were.
So, yeah, I have no idea how that'd work out. If I had a virtuous partner, it'd probably be easier. Oh, oh, can I have 616 Shadowcat? She's pretty virtuous. And super OP.
