I’d probably get the Taskmaster’s powers, whcih is the ability to learn something just by viewing it. And that does mean anything. So if I see a person perform a martial arts move at the level of a black belt, I too could perform that move with no previous training. It would be the same thing if I were to view a grandmaster chess player playing a game. Thank god I’m only watching the game, controlling it… 50 geek points to the person who can tell me where I got that quote from.
I’d also go with being able to influence someone thru emotions. While you could do the same thing by just changing into the president or the person you wanted to affect’s loved one, they’d still be doubting. I could tell them what I wanted, and cause various emotions to remove doubt or questioning from my request.
Having the power of the Resurrection Man would be pretty nice. Every time you die, you come back as a different person with a power based on how you died. You could be unstopppable, being able to rule the world because like a cockroach you’d never die for real and you’d evolve quickly from what killed you. They shoot you, you come back bullet proof.
Out of the three, I’d most likely go with the first one, because I’m very clumsy, don’t really like to manipulate people or have people become violent or have myself perform violent actions.
