In all honesty, given superpowers, I would lean towards the villain spectrum. So, no. I'd rather not. Unless it was a power like that one kid in the one X-Men movie that could chamge the television channels by blinking. That would be awesome, and how could I possibly use that for good or evil?
And, being a huge Watchmen fan, is there even such thing as a super "hero"? Had to throw that it.
Gee... IDK if I would have the energy to do the whole saving the world thing. I suppose I could always try to help people in small ways. In any case, if I were to accept, I would choose the power to read minds, since I often wonder (and in some cases worry) about what other people are thinking. It'd be nice to know for sure.
And I would make a totally awesome superheroine! The problem would be, would I want to go for a more traditional American style hero or for an anime Magical Girl type.
Definitely go for an anime girl type. The traditional American type seems to invariably involve costumes that are constantly on the verge of a major wardrobe malfunction. At least with anime girls, you can wear some real clothing.
