Soldato
Bending time and space like Hiro Nakamura.
What would it be and why?
I would want heat-vision. The ability to cook food by looking at it would never grow old.
I could even squint slightly at a woman to get her to strip from the heat so everyone's a winner.
Insta-Attraction!
Being the sexiest man alive would never get old.
I'd take teleportation.
Super Speed, ala The Flash.
That way I could be in a bar and sneak drinks from behind the counter without the barstaff knowing. I would also save on train fare when coming home from University.
Even assuming your insides don't get squished by 30Gs of force your senses wouldn't be fast enough so you wouldn't see anything coming, at that speed a fly would probably do a fair amount of damage. If your senses were fast enough everything else around you would seem painfully slow.
I can't see how this character ever made it through 1 comic, let alone one frame .
invisibility for me!!!
Infinite health.
The ability to absorb the super powers of other people, Peter Petrelli style
My superpower would be to have whatever superpowers I wanted.
