This is probably way too obvious to even be interesting if you know me, but here goes. If given the choice I would have to go with super intelligence. My alter-ego, Tony Stark aka Iron Man, is arguably the smartest person on Earth. (Evidenced by conversations and a chess game had with Reed Richards in the Illuminati or was it The Invincible Iron Man) Either way with my big ol’ brain I would be able to solve just about any problem. Not only that but I would be thinking up and creating all the coolest and most useful things. That and progressing the human race. Totally, intelligence. Who needs flying or laser beams when you can just make a suit that enables you to fly and has repulsor rays.
