Mike Tyson's Mansion, Ohio, United States

Nicknamed "Kid Dynamite" and "Iron Mike", Tyson won his first 19 professional bouts by knockout, with twelve of them occurring in the first round. He unified the belts in the splintered heavyweight division in the late 1980s to become undisputed heavyweight champion of the world. Tyson became the lineal champion when he knocked out Michael Spinks in the first 91 seconds of the fight. Tyson lost his titles to 42-to-1 underdog Buster Douglas on February 11, 1990, in Tokyo, Japan, by a knockout in round 10.
In 1992, Tyson was convicted of sexually assaulting Desiree Washington, for which he served three years in prison. After being released from prison in 1995, he engaged in a series of comeback fights. He regained a portion of the heavyweight title, before losing it to Evander Holyfield in a 1996 fight by an 11th round TKO. Their 1997 rematch ended when Tyson was disqualified for biting off part of Holyfield's ear. He fought for a championship again at 35, losing by knockout to Lennox Lewis in 2002. Tyson retired from professional boxing in 2006 after he was knocked out in consecutive matches against Danny Williams and Kevin McBride.
