The 54-year-old ex-boxing superstar is widely revered as one of the most dangerous punchers and best boxers in history.

And footage has now emerged of the ‘Baddest Man on the Planet’ in his dressing room ahead of the Lou Savarese fight in 2000.

While he was far from the prime Tyson of the 1980s, the boxing legend appeared to relish the fact that he was in his element.

‘Iron’ Mike practised his trademark ‘peek-a-boo’ technique, despite making it difficult for one of his team members to tie up his groin guard.

Tyson became increasingly aggressive watching a fight on TV and started trash-talking before two members of his camp smeared his upper body.

Even fans have acknowledged how Tyson acted like a caged animal that was ready to be let loose on his prey.

Boxing fan Joey Trimble wrote: “he really was treated like an animal… the way he’s pacing back and forth like a pitbull in a cage before the dog fight… insane [sic].”

While another fan pointed out: “Mike was always the smallest heavyweight but look at the size of him compared to the guys rubbing his shoulders. Just a tightly packed mass of rage!”

YouTube commenter Shafo said: “Everyone in there is terrified of Mike haha.”

A fourth fan added: “He was serious about his business. I kind it. He not being intimidating. He getting ready for a show.”

Tyson would secure a first-round TKO victory over Savarese at the Hampden Park in Glasgow.

As intimidating as Tyson was in his dressing room, the former undisputed world heavyweight champ was widely admired for his menacing ring walks.

And the entrance he had in his first-round demolition of Michael Spinks remains one of the most spine-chilling ring walks in history.
