If you had a super hero,what would they do/be?

I haven't worked out everything,but I came up with a guy who is missing a bunch of glands in his head,so hes immune to all the harmful effects of bodily toxins.Like he can down a gas can full of everclear and still retain all his awareness,but not feel pain.Or take a crapload of steroids and get ripped,but without getting all irritable or suffering from shrinkage.He does hallucinate though,which is why he talks to his firearms.and they all have different personalities.Like he has a .44 Magnum that talks like Dirty Harry,and a Lee Enfield who acts like an old english gent.He lives in a houseboat off the dock of a junkyard,and uses all the stuff there to build his own private arsenal (Swat Kats anyone?).
