magnetos telekinesis power
the ability to control water, water bending
The power to create any sort of matter. Money,food , anything. I think that's the most practical power.

Master of Time and Space (like Hiro Nakamura for any of you Heroes fans out there)
And on a personal note random_love, this power would allow us to go and see the 9th season of HIMYM already!
