the problem with flight.. is once you move fast enough.. you're gonna need protective gear, and you'll hate yourself the day you fly without long pants, long sleeved shirt, and most importantly a helmet. It would hurt in the rain too... It be like a convertable with the top down on all sides.. ouch.
Invisibilty would be cool too, but not without its problems. I mean people would run into you... you'd regret the day your cross the road invisible. Think if your car went invisible...... You'd get in a wreck no matter where you went. Invisiblity would be pretty neat tho.. and not just to check out women either... but of course the thought has crossed everyone's minds.
oh and um HedgeHog... umm
I think I'd take teleportation. Forget your keys? BAMF! BAMF! got 'em!
Um, what do you need keys for?
