Best power imaginable for me is telekinesis. Can't think of a super-hero, because telekinesis, being so OP, isn't exactly very common in heroes. Probably the second best would be a set of powers like Hiro Nakamura from Heroes. Oh right, jean Grey from X-Men has telekinesis, but she hardly uses it at full potential.

What's all this stuff about genies, dude? Don't forget that genies are typically also slaves of some kind, and while housing the ability to bend reality they are also typically bound by unbreakable rules.

In the case of someone gaining "genie powers", they would probably develop a heavy restriction or flaw to go with it. SO SAYS THE MIGHTY GM. gavel hit

Neverending possibility of self-improvement of mind and body (out of human reach but remaning with human look) + Neverending life/invulnerability = Evolving as many powers/skills you need by having enough time to teach them by yourself. I don't care if i go crazy at some point for few bilions of years, some day i'll get back my mind but improved by everything i learned thanks to being crazy or evolve enough to live as new kind of existence. As long as i'll be evolving, there will always be some thing to do even it would be flying in space by some mental ability to push myself by telekinetically forming matter floating close to me and watch some awesome views in space in vision/spectrum not known for present man. Having evloved mind may let me start to live in some other dimension and have higher capabilities of thinking/calculating/planning/understanding enough to evolve faster, to adapt myself everywhere (for example i won't get bored with elapsed time spent on "slow" flowing in space because of mind accustomed to it enough while remaining on full awarness), etc.

I would like to have a Super Power where you can steal or erase other people's super power expect mine's

Silly, if you're a genie you get trapped in a lamp and you have to do what other people say.

I'd like the ability to manipulate, rewind, and modify the universe, so it's kind of like hitting f12 in Dirt except more fun.

Mind-reading. You could do so much with this and build much wealth.

I'm not sure if it's a superpower, but I always wanted to be one of comic super scientists, You know the type that can make things like Force field emitters and matter transporters, or anything else you can imagine.

It's kinda a cheat as you don't have any innate powers, but a lot of devices that give you access to almost any other power you could want. Oh and you get robot helpers, all be it robot helpers that will someday try to take over the world, but nothing's perfect,

the best super power is the ability to copy any other super power.. i have all your superpowers in me :p

Wolverine's healing factor!

I'd like to have the power that the most awesome and badass superhero in the history of comics has - the ability to communicate with squirrels.
