There's a bunch of possible powers I'd think of that'd be cool, but for the sake of taking the raunchy options, I suppose I'll take in invisibility and X-ray vision.

Either that or the ability to interface myself with technology. Would make dumping my Satellaview 8M Packs a lot easier.

I don't know about being a superhero but if I could have one power it would most definitely be teleportation.  Just think waking up in the morning and after your shower, get dressed and eat breakfast and instantly you're at work.  No traffic or smelly train rides, no getting stuck in a dirty packed subway.  Anywhere you want to go your there when you want.  When you're  finished with work, clean up for the day you don't have to sit in at least an hour of jerks cutting you off to get 1 car length ahead just to cut back in the other lane and get nowhere or worse now block the lane, just presto home again. With this power you don't need to fly and you get there faster.  Plus do you know how cold it would be to fly at any rate of speed (your body isn't designed to advert wind like a bird.)  The time thing would be good too but I'm a simple man and I just to save time in my life to do better things with.  And avoid the crazies on the roads. That's just how i feel

I  would choose power over time. Because really you could do almost anything if you could control time. Like freeze time and do whatever you wanted in that time. It would be plain awesome. 

sonicfan&mariofan1991:to run on walls you just need sucsion cups and I mean every thing else you just need to be able to fly the flow of gravity is something that forces you to fall when you jump so if you were to go into space and make the gravity pull more power full you would fall down and on the moon if you were to do the same again you would just fall faster not to be a downer I do see a point to controlling gravity you just gotta specify what your point is for example if I were to control gravity I would make it so that my villain would be affected by a large gravitational pull or magnetic wave forcing it to the ground meaning that it must stay put and not move or not jump or there for fly but this may affect the surrounding terrain like the people and other things in said area if the pull/wave was even slightly not bounded the leaves of the trees would be sucked off and large or small buildings would fall and so on.There for destroying the area so you would be a villain as well even though you would stop the "original villain"so you may also want to put some theory on boundary lines for the super power so sorry if I was a downer or if you found this insulting I just wanted to go into detail of your super power.
