Michael Gerard Tyson, born on June 30, 1966, in Brooklyn, New York, USA is a professional boxer and former World Heavyweight Champion. The youngest man to win a heavyweight title belt, he was rated by Ring magazine, in a 1999 listing, as the fourteenth greatest heavyweight of all time. He was nicknamed "Iron" Mike Tyson, Kid Dynamite, and The Baddest Man on the Planet.During his prime he was the most feared man in the heavyweight division, but his once promising career was undermined by personal problems, lack of preparation, and periods of imprisonment. Upon release following his first prison sentence, he made a heavily anticipated comeback but failed to reclaim his previous dominance. On June 11, 2005, Tyson suffered a defeat to journeyman Kevin McBride, and shortly thereafter retired from the sport.
