Perhaps Iron Mike's greatest-ever performance came in his 28th fight, when at the age of 20 he became the youngest-ever Heavyweight champion of the world by beating Trevor Berbick in 1986.
As a boxer Berbick will be remembered by most for not only the Tyson fight, but also for being the last guy to fight Muhammad Ali.
In May 2010 Tyson described his motivation for the Berbick bout, "I just thought that he didn't have to do that. This guy, Ali, was absolutely helpless…Ali couldn't do nothing."
After the Tyson bout, he was never the same in the ring and was always seemingly in trouble outside of it.
He had a stint as a Pentecostal preacher in Las Vegas, he fought a wrestler in the Japanese UWFI and had an infamous street brawl with former Champion Larry Holmes, footage of which can be found on YouTube.
Unbelievably he fought his last bout as late as 2000 in a fight which he actually won, but soon after he had his boxing licence removed due to a discovery of a blood clot on his brain.
Berbick’s life was so crazy it almost makes Mike’s appear normal. Born in Jamaica, raised in Canada and fighting in the United States, he never seemed at home.
In 1992 he was found guilty of sexually assaulting his children’s babysitter for which he was sentenced to five years imprisonment but served only 15 months. In 2002 he was deported from the United States for the second time in five years and his problems did not end there.
Berbick would spend the next four years in and out of trouble before being found murdered at a church courtyard in Jamaica in October 2006. He died after being hit repeatedly in the head by a steel pipe. His murder was described as being so violent that it mirrored his own life. Two men were arrested for his murder, one of whom was Trevor’s own nephew, Harold.
