Something I like to call mind-hacking: Imagine your mind's a computer, I am the hacker who always breaks in. Everything about that person is thrown open, you can implant into them the thought process to do whatever you want.
I've always wanted Aquaman's powers. Swim to any depth without succumbing to water pressure, breath underwater, see perfectly underwater, and communicate with ocean life.
I would like the power to manipulate the space-time continuum, which would basically end the possibility of aging or death, of course I'd be capable of moving from one galaxy to another with ease, possibly even travel to other dimensions and locations in the multiverse, stop time, speed up time, you name it as long as it exists in the probable laws of physics I would be capable of doing it. Oh, space-time, how I love you.
I have three I'd have to choose from, being able to teleport, being able to turn invisible, or the power to completely control time in any given space.
The power to control Electricity has always seemed a nifty trick to me. You can power most things, charge various items and metals, and recharge by sticking your finger in a socket!
Take that a step further with Mind control As for my power, Ki manipulation (Flying and energy blasts?! Awesome!) Or Thu'um (I could basically do alot more than ki manipulation, but no flying. hm....) :O OR THE TRIFORCE OF POWER! I COULD DO ALL THOSE THINGS!
It doesnt beat me either.Im practically invincible.And as i said earlier.I can just eat you and gain your powers.At that point i could destroy the entire universe.
