Something that would only bring me good i know that sounds stupid but a lot of powers are bad. Like i was gunna say read peoples thoughts but you might hear things you dont want to. I would have to say flying though that would be awsome.
The ability to control and manipulate water any way I see fit. Put out fires, suck up water to prevent mudslides and... build a giant slide that soars into the sky. Of course, I'll be charging $5 per ride.
I would have infinite senses. So my eyes could see anything, I could smell anything I saw, i could listen to anything i saw, i could touch anything i saw, or even taste anything i saw. How cool would that be?
