*Super Strength
*Super Speed
*Flying abilitie
*Mind control
*Mind reading

*Controlling Time and Space.

I'd like to be able to control Time and Space as It'd come in handy...freeze time a moment while you runs off to da store for a bite to eat before class without being late? !!! Extra chance to do your homework or see a program you love. Speeding up time to get past boring lessons? YUP YUP. Dat is defo the Power mes would wanna habs (:
