'Iron' Mike Tyson's most notorious fights

Mike Tyson is one of the greatest heavyweight boxers of all time.

His frightening demeanor in and outside the ring and vicious knockout power earned him the title 'The Scariest Man in Boxing.'

Let's look through some of his most notable fights in a career that spanned 20 years.

Tyson's fight against Peter McNeeley is unanimously known as the 'He's Back' fight, making his first appearance in the ring for four years after serving prison time for sexual assault.

Tyson's fierce ring walk said it all, demolishing McNeeley within 89 seconds with a hard-hitting uppercut, knocking him out.

Mike Tyson's first professional fight was against journeyman Hector Mercedes on March 6, 1985, at age 18.

Tyson beat Mercedes via first-round technical knockout, starting a streak that saw Tyson win 26 of his first 28 fights via TKO or KO.

One of the most notable matchups in Tyson's career was his final bout, fighting Irishman Kevin McBride on June 11, 2005.

The fight was a labored one, with both failing to create that crushing blow to get the win. In Tyson's sixth and final round, he attempted to break McBride's arm and headbutt him before retiring from the fight before the seventh round, meaning McBride won by technical knockout.

The fight billed as 'Once And For All' was the boxing match between the unbeaten stars of Mike Tyson and Michael Spinks in June 1988.

'Iron' Mike held all three belts, whilst Spinks was The Ring and Boxing Illustrated magazine champion. Tyson silenced the doubters, knocking out Spinks in 91 seconds.

The night Mike Tyson made boxing history was his first world title shot against Trevor Berbick on November 22, 1986.

A 20-year-old Tyson knocked out the 33-year-old Berbick in five minutes and 35 seconds, becoming the youngest-ever heavyweight boxing world champion of all time.

Hungry for a world title after coming out of prison, Tyson had his eyes set on taking the world title from British heavyweight Frank Bruno in March 1996.

Due to his prison time, many people weren't sure he could fight at the world title level anymore. However, Tyson scored a third-round knockout, becoming a world champion again at 29.

Tyson always had a reputation for severely trying to hurt people in the ring. According to evolve-mma.com, Before his fight with Donovon Ruddock, he said, "If he doesn't die, it doesn't count. If he's not dead, it doesn't count."

It was a war-like display from both fighters, but Tyson got the job done in round seven of the fight via technical knockout after knocking Ruddock down in the second and third rounds.

With the WBC, WBA, and IBF world heavyweight titles on the line, Mike Tyson fought the formidable Larry Holmes in trying to protect his belts.

Tyson masterfully picked apart Holmes, sending the veteran down three times in the fourth round. Before the fourth ended, the referee saved Holmes and stopped the fight.

On June 28, 1997, Tyson fought Evander Holyfield in the pair's second fight after Holyfield defeated Tyson in the first matchup in 1996.

The fight ended dramatically and is remembered as one of the most bizarre moments in sports history. Tyson was disqualified from the match in the third round for biting a chunk of Holyfield's ear off.
