I'm sure there are threads like this, but I'll contribute anyways .
A superpower/superpowers that I would like to have would be superpowers equavelent to SuperMan's, ability to freeze time, or something like telekinesis so I could read people's mind's and such.
I have to say the ability to send large masses of healing... "Things"... that heal the wound in milliseconds, the on command thing is so that my mega secret identity will not be found out if I am injured outside of superheroness, or even if I feel like retiring.
If not that I would go for super strength. If you don't get shot your pretty golden it seems.
Wishlist: Super strength Invincibility Morphing capabilities (Much like the "Animorphs" tv show... anyone watch it? Laser vision (Hey, people cant run without legs.)
I'd take lightning, not overly useful but pretty freakin awesome. I think throwing lightning bolts and summoning storms would be all kinds of great fun.
