Batman.

Hmm... As I recall, I chose flight.

I SHALL BE KNOWN HENCE FORTH AS...

-pause for dramatic effect-

WHOOSH MAN!

Or if I'm a villain, then

THE ELUSIVE GALE!

... Hmm... Yeah, that second one sounds cooler... Well, if you need me, I'll be steering migratory birds in the wrong direction this winter... (so evil! ;-; )

Flying Man.

Heat Man.

I know. I suck with names.

Knock-People-off-Bicycles Man. Because, let's face it, with telekineses that's probably what I'd do.

Cise =D

Flying Man.

-gasp-

My mortal enemy...

Steelmind. For great references.

My real name.

I was incredibly cheap when I picked my power, but at least I wouldn't have to spend much time worrying about my family ever being in danger. Unless... Oh no! What if my archenemy has a similarly-cheap power? Hmm...

What if I just refuse to give my name and let the world decide upon a name for me? They can only call me that-teen-who-randomly-appears-and-beats-all-the-bad-guys for so long before it just gets to be too much of a hassle. I may or may not like their idea, but at least it wouldn't be official.

Maybe...?

Blargh

Great title, ain't it?

Superman.

Because I already go by that name and I already have a collection of Superman shirts.
