Chuck was caught rather unprepared by the blow. After all, he was still busy taking stock of the situation. A giant gorilla in funny clothes wasn't exactly something one saw every day and he just had to stop and stare while his mind tried to process its dynamic entrance. It was a good thing he was staring, since he could see the blow coming and managed to raise his arms to protect himself on instinct, even if he couldn't brace himself or anything. He was knocked straight off his feet, a first, and as his jacket flew off his hand he rolled around the floor and smacked his back against a stone wall. A trickle of blood emerged from his broken lip. It'd take him some time to realize that he should have, by all rights, died right there or at least suffered severe injuries, but the shirtless teen was busy being pissed to notice at the moment. Hell, he was so pissed that the pain, while noticeable, was metaphorically put in the back burner. He'd had about all he could take, and the straw that broke the camel's back was getting smacked around for no reason by a goddamn ape. While that other guy was still going on about dancing Chuck charged full speed at the ape, screaming "MEN FIGHT!" at the top of his lungs as he launched himself at the back of the creature's knee shoulder-first. Wasn't too hard, considering the size of it.
