If you had one power well it would be hot chick magnet (HOT BABES) =P My weakness though will be i also attract ugly chicks D: Now you post what you think is your power and its weakness.

Regeneration, always happens. Even if I die I am brought back to life.
My weakness would be breaking laws lol :P

Power:Pyrokenisis(ex: Meredith from Heroes) or Fire Manipulation(ex: Pyro from x-men), its something i really loved to have,
weakness: Freezing or Ice

other,
power:Space-Time Manipulation (teleport, time freezing and time travel), its would be awsome =D,
weakness: high risk on changing the present and future to worse or causing a time riot or something like that

It would be cool to be able to run 50 Mph.
Id run to see my dad in only a few hours of running(He lives in a completely different state)

My weakness would be the aftermath.I'd be so wiped out I'd fall the second I stop.

Invisibility :3 It would be very helpful when i dont wanna be seen.. And i can stalk people!
Weakness... Well, actually a fear - i will start stalking girls and my invisibility would suddenly end D:

Mind reading. Always useful if your joke career is Dictator of Da Werld.
Weakness: Psychopaths that would make me black out.

Flight. Just cuz.

The power to command crows.

Weakness: crows are generally pretty useless and wouldn't be able to understand very simple commands.

I actually know a person who could call a crow, would hold it, and let it fly around the house. I don't ever want to talk to that person again.

Have you read Cold Mountain by chance? Very nice book, it portrays crows as a symbol of Independence.

Also, I'd go for flight, although it'd probably make me lose track of time.
