You know, I've thought about this a lot and I've decided that while invisibility, flight, bullet-time or whatever are all cool, they're fairly impractical. So I decided long ago that the best power to ever have is the power to slap people in the face with my mind.
Not hard enough to injure, just enough to cause pain. I could slap anyone by just thinking about them, from anywhere on the earth. And they would never know it was me. They wouldn't even know what happened.
So the next time some guy goes "Hey, let's release another poor quality movie tie-in videogame," I just think about him and slap! he's holding his face and he doesn't know why. Some troll flames an internet forum, he gets the same punishment. Hollywood directors, idiot celebrities, crazy world leaders - nobody will be safe. It would be so satisfying and I'd be able to live my life more or less the same I do know, just feeling more fulfilled.
And if I had to take off my clothes to do it? Well, I'd probably be frequenting the bathroom much more, but yeah, I'd go along with it.
Although people would find it weird, I guess. "Hey, every time that guy goes to the toilet, another celebrity gets invisibly bitchslapped."
