Invisibility is definitely the most useful superpower. You could do so many bad things with it.

Rob banks, spy on people, push your enemies in front of a bus and get away with it...etc etc.

To fly and to control fire, water, wind and earth or just to control whatever I please with my mind.
Also super speed and be able to create force fields and breath under water.

+1 , also invisibility and invincibility

Reading minds.

Invisibility and flight.

would you have chance to meet them though
Invisibility is actually lame if considering your clothes can't be invisible
I WANT teleport

Time traveling, because I can know the winning lottery numbers, go back in time, travel to a state that plays the mega millions and win the money or premonition so I can predict the winning numbers

Never thought about it like that
