Since he can do it because of the yellow sun, it must be solar power......Yes, I would want to be able to fly only if it were as effortless as Superman has it.
Wait, he can fly at night too. Dang.
They guy I liked was J'on J'onzz (spelling approximate, and don't ask me about pronunciation). He had superstrength and could fly and was invulnerable (except to fire) and could walk through walls and be invisible and be a shapeshifter. Of course, for this thread's purposes, that's more than one power.
