Heroic-Villain.
I'll be all righteous and heroic, but your wallet will disappear and I'll be nowhere to be seen. I'm also a bit psychotic with my killing techniques and I'd break open an entire city for one criminal.
edit: I'd also not have any super powers or ridiculous costumes. Me, some military grade combat armour, a light sniper rifle, some explosives and a city full of muggers.
