Frozen. Then dropped into a crowded street from atop a skyscraper. Somebody is coming with me dammit! Plus, you can't really feel much after a certain negative temperature, with fire, you'd be all like, OH FUCK OH FUCK, IM ON FUCKING FIRE OH FUCK OH FUCKSNBORWNIOBPEWIJIO!!!!11212!!. Then you fall over and convulse all over the ground and shit. Totally embarrassing.
Ummm, based on the video game theory of fires, you could take out more people if you were on fire. Touch them, catch em on fire, and then EVERYONES just BURNING RED with embarrassment... you won't even be noticed.
