Don't forget, you have POWERS. You don't need guns, or getaway vehicles, or some elaborate scheme to become a bank CEO. D
I am a super villian! I'm on the evil league of evil! I'm not going to tell you how I rob banks because that is classified information.
use levitation skills to get the money but first knock out everyone in the cityand run off!!
Teleport into bank vault at night, take money, teleport out. Simple.
Why rob a bank when you can *own* one? If I were a widely-known super-villain I would use a phony business front to buy up a bank and then take deposits from terrorists, gangsters, and drug lords to handle all their cash finances. I would charge these badguys big fees to launder all their money and make myself rich that way. If anybody (cops or superheroes) tried to bust me, I would bribe them with lots of money and make them as crooked as me. If that didn't work, THEN I would use my super-powers to destroy them. If you rob a bank, you have money for a little while. If you own the bank, you have money for a lifetime!
telekinesis, baby! it's like everything! you can levitate, get the money out the safe without getting your hands onto it, defend yourself, etc
