All superheros have a great origin story, here's mine: I was just a normal guy walking down the street when I get struck by a massive bolt of lighting! This is when I get my super power, the ability to shake on the ground an sh*t myself. I generally have no control over this ability, so I'd use it randomly. It would be an excellent way to embarrass myself, make other people feel good about themselves, and generally ruin any chance I might have with a woman. Yay.
