MIKE TYSON was so dangerous in the ring that even he is scared of the man he used to be.

The American, 54, dominated the world of boxing after he was crowned the youngest heavyweight world champion in 1986, aged 20.

Tyson ended his illustrious professional career with a remarkable record of 50-6 with 44 knockouts – and he goes in pursuit of more in his comeback fight against Roy Jones Jr on November 28.

He was renowned throughout his reign for his incredible punching power – as well his petrifying ring walks.

When asked how he transformed himself into a knockout specialist, he credited his trainer Cus D’Amato.

Speaking to GQ, he said: “I think I was born that way.

“But I developed [my knockout ability] through Cus D’Amato telling me repetitiously over and over again to do this movement and to punch with this type of bad intentions.

“And just to have ferociousness and mean intentions whenever you throw punches and stuff.

“And try and punch through your opponent, not at him.”

He called time on his boxing career back in 2005, but SunSport have decided to look back at his five most devastating knockouts.

5. Larry Holmes – 1988
Tyson was 17 years younger than Holmes when the pair battled it out for the WBA, WBC and IBF titles.

Holmes had been out of the ring for nearly two years, but vowed to knockout his opponent on his return.

But his prediction came back to bite him as the younger, faster and stronger Tyson dominated him from the off.

Tyson dropped him twice in the fourth round, but Holmes managed to climb back to his feet.

The fight was waved off by the referee after Tyson put Holmes flat on his back with a heavy right hand.

4. Henry Tillman – 1990
Tyson had his reputation to redeem against Tillman following his devastating defeat to 42/1 underdog Buster Douglas.

And he was gunning for revenge against his fellow American after he lost to him twice in the amateur ranks.

But Tyson looked back to his best as he secured a first-round win over the 6ft 3in fighter.

He trapped Tillman in the corner before he put him on the floor with a routine right hook.

3. Marvis Frazier – 1986
It took Tyson just 30 seconds to find a way past Marvis Frazier – son of heavyweight world champion Joe.

He barely broke a sweat as he secured the quickest knockout of his career.

After he landed a brutal uppercut, Tyson dropped his opponent with a right-left-right combination.

Tyson proved he was worthy of a world title shot as he defeated his opponent in just 33 seconds.

2. Trevor Berbick – 1986
This was the fight that first penned Tyson’s name in the record books.

He became the youngest heavyweight champion in history at the age of 20 years, four months and 22 days.

Tyson looked ferocious as he sent his opponent crashing to the canvas in the early stages of the second round.

He followed it up with a historic left-hook which left Berbick flopping around the ring.

1. Michael Spinks – 1988
Tyson left Spinks’ undefeated record in tatters as he battered him in just 91 seconds.

The American knockout specialist left fans stunned as he retained the undisputed heavyweight title.

He dropped Spinks with a right hand to body then sealed the deal with a terrifying left-right combo.

Hall of Famer Spinks admitted he “came up short” before he announced his retirement from boxing after the fight.
