<human>: 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.

Tyson made his professional debut as an 18-year-old on March 6, 1985, in Albany, New York. He defeated Hector Mercedes via a first round knockout. He had 15 bouts in his first year as a professional. Fighting frequently, Tyson won 26 of his first 28 fights by KO or TKO; 16 of those came in the first round. The quality of his opponents gradually increased to journeyman fighters and borderline contenders, like James Tillis, David Jaco, Jesse Ferguson, Mitch Green and Marvis Frazier. His win streak attracted media attention and Tyson was billed as the next great heavyweight champion. D'Amato died in November 1985, relatively early into Tyson's professional career, and some speculate that his death was the catalyst to many of the troubles Tyson was to experience as his life and career progressed.  Tyson's first nationally televised bout took place on February 16, 1986, at Houston Field House in Troy, New York against journeyman heavyweight Jesse Ferguson. Tyson knocked down Ferguson with an uppercut in the fifth round that broke Ferguson's nose. During the sixth round, Ferguson began to hold and clinch Tyson in an apparent attempt to avoid further punishment. After admonishing Ferguson several times to obey his commands to box, the referee finally stopped the fight near the middle of the sixth round. The fight was initially ruled a win for Tyson by disqualification (DQ) of his opponent. The ruling was "adjusted" to a win by technical knockout (TKO) after Tyson's corner protested that a DQ win would end Tyson's string of knockout victories, and that a knockout would have been the inevitable result.  On November 22, 1986, Tyson was given his first title fight against Trevor Berbick for the World Boxing Council (WBC) heavyweight championship. Tyson won the title by second round TKO, and at the age of 20 years and 4 months became the youngest heavyweight champion in history. Tyson's dominant performance brought many accolades. Donald Saunders wrote: "The noble and manly art of boxing can at least cease worrying about its immediate future, now [that] it has discovered a heavyweight champion fit to stand alongside Dempsey, Tunney, Louis, Marciano and Ali."  Tyson intimidated fighters with his strength, combined with outstanding hand speed, accuracy, coordination and timing. Tyson also possessed notable defensive abilities, holding his hands high in the Peek-a-Boo style taught by his mentor Cus D'Amato to slip under and weave around his opponent's punches while timing his own. One of Tyson's trademark moves was a right hook to his opponent's body followed by a right uppercut to his opponent's chin. Lorenzo Boyd, Jesse Ferguson and Jose Ribalta were each knocked down by this combination. CANNOTANSWER
