I only need one: The power to give myself super powers. If that's not allowed, then... 1. Fly- Flying is awesome! Go anywhere really fast! 2. Read minds- That would be so cool, I could know what people think. 3. Travel through time- Take a test, get a bad grade on it, go back in time, take it again and get 100%. Or when you say/do something you regret, just undo it. Also pausing time would be cool. I'd never be late to class again!
1) Read minds selectively. 2) Turn into an armed, fire breathing, time travelling, shapeshifting, super strong, fast running, power dragon. 3) Transport anything from any point in the universe to an area of my choice.
See, with #1 I can mind read selectively, I can get to anyone and anything, even become politically powerful to make the whole 'helping the world be better' thing come alive.
With #2 I can pretty much destroy any one or thing that comes in my way.
With #3, I can pull resources from the entire universe, not only making myself insanely rich but I can help all of humanity with unlimited resources, virtually ending the idea of an economy.
I would like to have the power to control electricity, teleport, and to see through walls . Why?
With controlling electricity I can easily kill someone by just draining the electricity in their bodies, heal people, and other cool things. Teleporting because I don't have to worry about being to late for anything or having to sit on a plane for hours if I want to take a vacation. Seeing through walls since it would be nice to see what's going on in other classrooms in my school.
I would want the power to control time and space, because that includes time travel, stopping time, teleporting, and controlling the space around me thus creating a shield or making the space in front of me look like the background so no one could tell I'm there. The power to live without oxygen, so I could travel to space and not die. The power to change shape and color at will so I could look like a small mammal, go to the girl's restroom and freak them out and turn into a fly to eavesdrop in private conversations.
I would pick animal morphing, power negation, and concussion beams.
With animal morphing I would have the speed of a cheetah, the physical strength of a gorilla, flying ability or a bird, and more. For power negation I could cancel out the powers of other. Like if someone who's evil has super strength and while he is holding something like a bus or big chunck of cement, I could cancel it out while he's holding it and it would crush him. For concussion beams I could do something like cuting through an enemy tank or battleship. But most likely a tank.
