Meh... Superheroes.
If I could do anything, I'd go with teleporting and telekinesis.

Yes, I'm just that lazy.

[EDIT] Being able to move my own conscious self around by leaving my body where it is would be pretty neat as well...

If I was a superhero I think I would prefer to be one more "realistic" like Batman, Nightwing or Green Arrow. If I have to choose between superpowers I would like something like The Flash , Spiderman or Deadpool

I'd love to have an evil alien symbiote.
I'm not quite sure what exactly would I do with it and the strenghts it would give me, but I think I could come up with something... there's plenty of people that I hate, after all >:)

I would like to have the power to stop time :D

Just think on the possibilities...

A Green Lantern ring would be cool, make anything as long as it comes out green.

And flight. - sounds good to me.

Let's end this thread...
Dr. Manhattan have best superpower ever, nothing can win that superpower and he can't die. End.

I'm very partial to Nightcrawler too. Even just his crazy agility is wonderful, but being able to teleport like that would be brilliant.

Nightcrawler + Mystique + flying

Genie FTW

Time travel power
.....just because I'm curious about the past and the future :D

Just found this.

Teleportation would be cool but I might clip into stuff/people. Flight would be cool but there's airplanes and crashing to consider. Super Speed is great but without durability or invulnerability to kinetic force I'd burn up like a scrap of paper... not to mention crashing into things and going squish. Regeneration? When does the body know when to stop to prevent tumors?

Psychic powers are all well and good but mind-reading is not only an invasion of privacy (whether passive or active) but people think all the time. How to sort through all the random thoughts and memories flashing at you like a flood would require training or exposure. Neither of which I'd enjoy particularly when thoughts veer towards the raunchy and morbid. Odds are high that I'd go crazy and what if I can't distinguish someone else's thoughts from my own?

Ultimately I can't pick a power. Too many what-ifs and expressions of the ability exist to make a definite decision. Between DC/Marvel, independent super hero comics, and the web-fiction Worm... Well, you get the idea. Not to mention that if I had some particular power and if people knew of it, I might get forced into things or be regarded as a scapegoat for problems I 'could' had fixed (regardless of being aware of them or not).

I know this is all for fun but my mind often goes towards the negative aspects of having powers as well as the good.

I'd go with Superman on this one. I mean, supersonic flight and invulnerability are all I wish for in this life.
Just think of the possibilities.

Superheroes time

Teleportaion, Time Manipulation, Reality Warping etc would always be exciting, but it would be a bit OP.
For a more simple but practical power I always wanted to have Precognition.

No one wants superpowers?

The power to create whatever I want with just thinking about it (like Maxwell with his notepad).

I want to be Batman, but im afraid my parents would die if i try.

freeze time for everyone besides me or anything i touch!

Super Saiyan!

Velcro man ;)

I'd be the Pumaman!
http://www.imdb.com/title/tt0081693/
As a Pumaman, I would have:

• An Aztec serial killer who throws random people out of skyscrapers windows as a sidekick.
• The power of flying by simply bending over to tie my shoes!
• The power of projecting major cities behind myself.
• The power of walking through walls, just like a real puma!
• The power to rip bricks off a wall with my bare hands for no reason.
• The power to teleport to any known location (pumas do that all the time).
  My only weakness would be old men. Pumamen have a hard time wrestling with old men in a suit.

This is a topic that has come up multiple times in conversation with friends, so I've put a lot of thought into this one.

In order of importance (basically a matter of "if I can't pick 1, I'll pick 2," etc.):
Omnipotence -- Basically the "I wish for a thousand wishes" of super powers. :P
Immortality -- With time, anything is possible. Even in the most hopeless of situations (buried alive, lost in space, etc.) there is always potential for things to get better. Being completely immune to pain and damage would be nice too, but not necessary.
Time Travel -- Assuming there's no crazy catch to this one (meaning no scenarios of, "You travel to X time, but because the earth has moved in space, you now travel to the space where the earth USED to be" or "You travel forward, but you can't travel back" or "You travel back and create a time paradox that ends the universe."), I'd travel forward to the height of human technology and hopefully become immortal, or at least mostly so.
Controlled Phasing -- The ability to move through solid objects at will. I could save lives, learn secrets... and go many many places I'm not supposed to go, returning with many many things I'm not supposed to have. >.>
Targeted Mind Reading -- Lots of people would say they don't want to know what people really think about them... I am not one of them. I hate secrets.
