Mike Tyson was only 20 years old when he won the WBC Heavyweight Championship. With the help of Cus D’Amato, Teddy Atlas, and Kevin Rooney he became the youngest heavyweight champion.

A quote from one of his interviews:

“I was gonna rip his heart out, I’m the best ever.  I’m the most brutal and most vicious and most ruthless champion theres ever been theres noone can stop me. Lennox is a conqueror? No. I’m Alexander, he’s no Alexander. I’m the best ever. There’s never been anybody as ruthless. I’m Sonny Liston. I’m Jack Dempsey, there’s no one like me.  I’m from their cloth. There’s no one that can match me. My style is impetuous. My defense is impregnable, and I’m just ferocious. I want your heart. I want to eat his children. Praise be to Allah!”
