[tps_header]10. Mike Tyson[/tps_header]
In his prime, the Brooklyn born, “Iron” Mike Tyson (50-6, 44 KOs) was known as the baddest man on the planet.
He is one of the hardest punchers in the history of the sport, having eradicated his first 19 opponents by knockout, 12 of those in the first round (per Wikipedia).
Tyson is the only Heavyweight in history to unify the WBA, WBC, IBF and lineal titles.
Tyson struck fear in the hearts of many opponents before even landing a punch. One of his most notable victories came against Michael Spinks for the lineal title, which he won in 91 seconds.
