Ya, this is kind of like the <a href="http://www.sciforums.com/showthread.php?s=&threadid=21943">Your Superpower of Choice</a> thread...
I believe I mentioned Captain Scarlet.
The Indestructible Man!
And, you know, time control blah blah power cosmic blah blah immortality blah blah bend iron bars with your mind. This is territory well trodden I think.
One guy asked for Omnipotence but not Omniscience which leads to the possibility of an all-powerful retard... I think there was a movie about this not long ago.
Anyway, when considering super powers that control things, you should always bear in mind the Law of Weather Control:
"Once you take responsibility for something, you can't give it back."
Them: Mr Elementalist! It's not hot enough!
You: K, now it's hotter.
Them: Mr Elementalist! We want a dry heat!
You: K, no more moisture... plus a cooling breeze.
Them: Mr. Elementalist! We want it shady!
You: K, here's some cloud cover.
Them: Mr. Elementalist! A tornado just sucked up our houses!
You: Well, you asked for it, you bunch of "I want colliding temperature fronts but I can't take the consequences" losers.
