I'd go with invisibility, depending on whether or not clothes become invisible. If they can, that means you can hide things under your clothes.

Tough one. Leaning towards flight since invisibility doesn't seem to extend to clothes.

If anyone thinks invisibility would be cool. Science tells us you would be blind. Without the light reflecting in your cornea, you can't see. So if you want no one to see you but you can't see them either is your fetish then so be it.

This is pure fantasy tho. If it was meant to be taken seriously, flight wouldn't be worth it either. You would either die flying higher heights due to many things, or even if that didn't happen, you'd be captured by some organization/government to be studied as that would impact everything. The best thing you'd be able to do with that would be flying at low heights during the night on some place that's not inhabited. 

If you can fly you can poop on Trump's head then fly like Superman faster than sound and get away. HA!

Invisibility.

Flight Forever!

Nice, I didn't think of that. But if you are invisible, you can throw poop at him many times, get away and never be seen. xD

But can't see where you are aiming. :P

?
You don't need to see yourself to throw something.
You are invisible not him.
