Mike Tyson (born June 30, 1966), nicknamed "Iron Mike", is a legendary American boxer who reigned as the undisputed heavyweight champion from 1987 to 1990 and is widely considered one of the most ferocious and intimidating fighters in boxing history, with an 88% knockout-to-win ratio. He became the youngest heavyweight champion ever at age 20, unified the WBA, WBC, and IBF titles, and won his first 19 fights by knockout—but his reign was shattered in 1990 by a shocking upset loss to underdog Buster Douglas. His career was marked by controversy, including a 1992 rape conviction (serving three years in prison) and a 1997 disqualification for biting Evander Holyfield's ear, though he later regained titles and fought Lennox Lewis in 2002. In November 2024, at age 58, he lost a highly publicized bout to Jake Paul, which became the biggest boxing gate in US history outside Las Vegas. Outside the ring, Tyson has become a cannabis entrepreneur, appeared in films like Rocky Balboa (2006) and The Hangover (2009), and has been inducted into the International Boxing Hall of Fame, cementing his legacy as a cultural icon.
