If you had any super power what would it be and why?

[JiraiyaSennin]

The power to create infinite amounts of electricity and absorb any electrical currents at any time.
Think:
I could solve the energy crisis.
Our nervous system runs on electrical impulses. Criminal doing wrong? I'll give him a seizure just by looking at him.
Oh, he's in a massive mech? I'm sure there are some electrical components in it. I'll just fry the circuits.

So you are essentially Static Shock.
