Invisable would be most intresting to me................id love to know whats going on in government and other social situations. id also sneak on planes and go to great holiday destinations.
Invisibility. I would be able to steal information, money, art, just about anything. I could use this power to expose government secrets and corruption, find out what corporations are doing and expose them, and sneak into a wide variety of interesting places.
I have all 3 anyway.
My superpower would be sanity ;)
invisible so you can bet up bad guys.
invisble. So that I can unearth some part of corruption...
Fly, the I wouldn't want to be invisible, I'd only end up finding out things that might upset me, although I might use it to pop into a few vivisection labs, freak everyone out as the animals fly out the door. :)
Seriously, you give me three powers and then you take two away? That's cold.
In any case, I'd choose TK. It has the most practical applications.
