^^ I agree to Scotch with the rocket launcher. Though, is you had any power that was exerted from your hands or feet, I would use them to shoot down and hope that it can carry me. Though one other thought that came to me was the ability to teleport, if you were skilled enough, you could teleport in such the smallest of distance you look as if you are flying!
(Also the power to span rocket jets out of your ears would be one)
Edit: I had to change a misspelling! CURSE ME!
If you notice you have a missing left arm on Thursdays, that was me.
