Título: Mike Tyson
Seção: Undisputed champion
Background: Michael Gerard Tyson was born in Brownsville, Brooklyn, New York on June 30, 1966. He has an elder brother named Rodney (born c. 1961) and had an elder sister named Denise, who died of a heart attack at age 24 in February 1990. Tyson's biological father is listed as "Purcell Tyson" (who was from Jamaica) on his birth certificate, but the man Tyson had known as his father was Jimmy Kirkpatrick. Kirkpatrick was from Grier Town, North Carolina (a predominantly black neighborhood that was annexed by the city of Charlotte), where he was one of the neighborhood's top baseball players.

Conteúdo: Expectations for Tyson were extremely high, and he embarked on an ambitious campaign to fight all of the top heavyweights in the world. Tyson defended his title against James Smith on March 7, 1987, in Las Vegas, Nevada. He won by unanimous decision and added Smith's World Boxing Association (WBA) title to his existing belt. "Tyson-mania" in the media was becoming rampant. He beat Pinklon Thomas in May with a knockout in the sixth round. On August 1 he took the International Boxing Federation (IBF) title from Tony Tucker in a twelve round unanimous decision. He became the first heavyweight to own all three major belts - WBA, WBC, and IBF - at the same time. Another fight, in October of that year, ended with a victory for Tyson over 1984 Olympic super heavyweight gold medalist Tyrell Biggs by knockout in the seventh round.  During this time, Tyson came to the attention of gaming company Nintendo. After witnessing one of Tyson's fights, Nintendo of America president, Minoru Arakawa was impressed by the fighter's "power and skill", prompting him to suggest Tyson be included in the upcoming Nintendo Entertainment System port of the Punch Out!! arcade game. In 1987, Nintendo released Mike Tyson's Punch-Out!!, which was well received and sold more than a million copies.  Tyson had three fights in 1988. He faced Larry Holmes on January 22, 1988, and defeated the legendary former champion by a fourth round KO. This was the only knockout loss Holmes suffered in 75 professional bouts.
