Mike Tyson - 'Iron Mike' - is a heavyweight boxing legend, known for his incredible 58 fights, 50 wins record (and perhaps a controversial fight with Evander Holyfiend, in which he bit off part of his opponents ear). Up there with boxing-ring icons like Muhammed Ali, Frank Bruno, Lennox Lewis and others, he's a household name and despite retiring, he's still a prominent figure to this day.
