Let’s say that you pissed off Superman so much that the only way he could deal with it was to punch you square in the nose! Maybe you were taking too long in the phone-box. Maybe he didn’t like the way you were looking at Supergirl (He’s hell incest-y like that!). What sort of devastation would that cause to your face?
Superman packs one hell of a punch. He can punch you all the way into space!! But some really clever people have broken it all down to speed, weight and atoms!! SCIENCE BITCHES!!
