David Deron Haye (born 13 October 1980) is a British professional boxer who has held world titles in two weight classes.
 He is the first British boxer to reach the final of the World Amateur Boxing Championships, where he won a silver medal in 2001.
 As a professional he became the first British boxer to become a unified cruiserweight world champion in 2008, winning three of the four major world titles, as well as the "Ring" magazine and lineal titles.
 In the same year he moved up to heavyweight, and became the WBA champion in 2009 after defeating Nikolai Valuev, who had a world record 9 in height and 99 lb weight advantage on Haye.
Hasim Sharif Rahman (born November 7, 1972) is an American former professional boxer who competed from 1994 to 2014.
 He is a two-time world heavyweight champion, having held the unified WBC, IBF, IBO, and lineal titles in 2001; and the WBC title again from 2005 to 2006.
 Rahman first became known on the world stage in 2001 when he scored an upset knockout victory against Lennox Lewis to win the unified heavyweight championship.
 Lewis avenged the loss and regained his championship by knocking out Rahman in a rematch later that year.
 Rahman won the WBC title (initially the interim version) for a second time in 2005 by defeating Monte Barrett, after which the WBC elevated him to full champion status by the year's end.
 His reign as champion ended in 2006 via another knockout loss, this time to Oleg Maskaev in a rematch of their first fight in 1999.
Gerry Cooney (born August 24, 1956) is an American former professional boxer who competed from 1977 to 1990.
 Despite his relative inexperience, Cooney's exciting wins and size, aided by expert promotion, gained him a lucrative bout with world heavyweight champion Larry Holmes in 1982.
 Cooney performed credibly before his corner retired him in round 13, and was regarded as having made a brave and determined effort.
 The view of him as tactically naive in defense was reinforced when former light heavyweight champion Michael Spinks stopped Cooney in five rounds in 1987.
 In his final bout, Cooney demonstrated his exceptionally hard punching power by staggering the powerful George Foreman, but was unable to capitalize on it.
 Cooney went on to suffer a devastating second-round knockout that ended his career.
Andre Michael Ward (born February 23, 1984) is an American former professional boxer who competed from 2004 to 2017.

 During his reign as light heavyweight champion, Ward was ranked as the world's best active boxer, pound for pound, by "The Ring" magazine and the Transnational Boxing Rankings Board (TBRB), as well as the world's best active boxer in the division by "The Ring", the TBRB, and BoxRec.
Evander Holyfield (born October 19, 1962) is an American former professional boxer who competed from 1984 to 2011.
 He reigned as the undisputed champion in both the cruiserweight and heavyweight divisions, being the first and to date only boxer in history to do so, which earned him the nickname of "The Real Deal".
 Holyfield is the only four-time world heavyweight champion, having held the WBA, WBC, IBF, and lineal titles from 1990 to 1992; the WBA, IBF, and lineal titles again from 1993 to 1994; the WBA title from 1996 to 1999; the IBF title from 1997 to 1999; and the WBA title for a fourth time from 2000 to 2001.

 He reigned as the undisputed world heavyweight champion and holds the record as the youngest boxer to win a heavyweight title at 20 years, 4 months and 22 days old.
 Tyson won his first 19 professional fights by knockout, 12 of them in the first round.
 He won the WBC title in 1986 after stopping Trevor Berbick in two rounds, and added the WBA and IBF titles after defeating James Smith and Tony Tucker in 1987.
 This made Tyson the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to successively unify them.
Christopher Cornelius "Chris" Byrd (born August 15, 1970) is an American former professional boxer who competed from 1993 to 2009.
