The title says it all.
If you were to have any ONE superpower, what would it be and why? What would you use it for? For nobility, justice, and all that stuff, or for evil and going places you're not supposed to?
I think that I would have teleportation. I would be like nightcrawler, and it would be awesome jumping around and teleporting from building to building, or inside movie theaters.
But that's just one thought. What do other people secretly wish they were able to do?
