I woke up blood gushing out my nose his punch was a direct hit. I would be able to take him im never one to give up. I got up and charged aiming my fist towards his face he blocked his face leaving his stomach open, I swung into his stomach which clearly stunned him. He quickly got on his feet and threw rapid punches in my direction, I captilazed on this dodging them and grabbing his arm and putting him into a headlock. I chocked him as hard as I could but he started elbowing me in the rib cage. He broke out and managed to land a hit on me before I got up. He has mores power in his than I do but the choking seemed to worn him out. He charged at with what looked like the little strenght he had left and tackled me. He procced to land several hits while on top of me inculding a hit in the eye I flipped him over and headbuttted him with all I had left. I got off of him and he was not moving his nose was bleeding and foam was commingout his mouth he had a concussion.
