Tyson, he broke his hand against another boxer in an alley fight.
Here is some information about him.
Tough man, driven, all the problems, in his mind, along with that he was dedicated to hurt others, mind over matter, he is the perfect example of it.
"I'm the best ever. I'm the most brutal and vicious, the most ruthless champion there has ever been. No one can stop me. Lennox is a conqueror? No! I'm Alexander! He's no Alexander! I'm the best ever. Theres never been anyone as ruthless as me. I'm Sonny Liston. I'm Jack Dempsey. There's no one like me. I'm from their cloth. There is no one who can match me. My style is impetuous, my defense is impregnable, and I'm just ferocious. I want his heart! I want to eat his children! Praise be to Allah!"
