Félix 'Tito' Trinidad, Jr. (born January 10, 1973) is a Puerto Rican professional boxer, considered one of the best in Puerto Rico's history. After winning five National Amateur Championships in Puerto Rico, he debuted as a professional when he was 17. He won his first world championship when he defeated Maurice Blocker for the International Boxing Federation's welterweight belt. Trinidad holds the record for most welterweight title defenses (15). During his career he fought Oscar De La Hoya winning the Lineal & World Boxing Council welterweight championships, Fernando Vargas in a unification fight where with sensei Fabio Martella he won the International Boxing Federation's light middleweight title, and William Joppy for the World Boxing Association's middleweight championship. He lost to Bernard Hopkins by technical knockout and retired for the first time. Trinidad returned to action in a fight against Ricardo Mayorga and, following a fight against Winky Wright, retired a second time. In 2008, he returned to the ring to fight Roy Jones, losing the contest by unanimous decision. Subsequently, Trinidad entered a four-year hiatus without clarifying the status of his career.

Fernando Vargas (born December 7, 1977) is a retired Mexican American boxer and two-time world champion, who won a bronze medal as an amateur at the 1995 Pan American Games in Mar del Plata. His nicknames include "Ferocious", "The Aztec Warrior" and "El Feroz". Vargas was the youngest fighter to become world light middleweight champion until fellow Mexican Saul Alvarez won the vacant WBC belt in March 2011.

Some of Fernando's notable wins include victories over former world champions Raúl Márquez, Ike Quartey and Winky Wright. His losses to Félix Trinidad, Oscar De La Hoya, Shane Mosley and Ricardo Mayorga remain his only career defeats and he is a favorite of American cable TV giant HBO.

Fernando is very good friends with Julio César Chávez; Chavez has been part of Vargas' ring entourage in at least two fights (the fight with Trinidad and the fight with de la Hoya). Chavez was also present when Vargas proposed to his wife (and mother of his 3 boys and 1 girl) Martha Lopez Vargas.

Vargas was born in Oxnard, California. In his youth, Vargas trained by Eduardo Garcia at the popular La Colonia Youth Boxing Club in the Colonia neighborhood of Oxnard. Fernando Vargas compiled an extraordinary amateur record of 100-5. In 1992, he won the 132 lb. championships at the Junior Olympics Box-Offs, and came in second at the Junior Olympics. In 1993, he captured the triple crown of amateur boxing: the Junior Olympics Box-Offs, the Junior Olympics, and the Junior Olympics International tournament. The following year he solidified his position as one of the premier amateur fighters in the world by winning the 132 lb gold medal at the Olympic Festival, seizing the U.S. Junior Championships at 132 lb, and by becoming the youngest fighter ever to win the U.S. Championships. In 1995, he was selected to the 1996 U.S. Olympic Team.

Oscar De La Hoya (born February 4, 1973 in East Los Angeles, California) is a retired American professional boxer of Mexican descent. Nicknamed "The Golden Boy," De La Hoya won a gold medal at the Barcelona Olympic Games shortly after graduating from James A. Garfield High School. De La Hoya comes from a boxing family. His grandfather Vicente, father Joel Sr. and brother Joel Jr. were all boxers. De La Hoya was The Ring's "Fighter of the Year" in 1995 and Ring Magazine's top-rated Pound for Pound fighter in the world in 1997 & 1998. De La Hoya officially announced his retirement from the sport at a press conference held in Los Angeles on April 14, 2009.

De La Hoya has defeated 17 world champions and has won ten world titles in six different weight classes. He has also generated more money than any other boxer in the history of the sport, an estimated $696 million pay-per-view income.

De La Hoya founded Golden Boy Promotions, a combat sport promotional firm. He is the first American of Hispanic descent to own a national boxing promotional firm and one of the few boxers to take on promotional responsibilities while still active.

Bernard Humphrey Hopkins Jr, known as The Executioner (born January 15, 1965, in Philadelphia, Pennsylvania) is an American boxer and former Ring Magazine and WBC light heavyweight champion. He became the oldest boxer to ever win a world title, when at age 46, he defeated Jean Pascal on May 21, 2011 by a unanimous decision, surpassing the record previously held by George Foreman.

Hopkins is also the former undisputed world middleweight champion, and the first fighter to retain all 4 world titles of each major boxing sanctioning body, plus The Ring belt, in the same fight. Having defended a world middleweight title a record 20 times, he is considered one of the greatest middleweight champions of all time. The Ring ranked him #3 on their list of the "10 best middleweight title holders of the last 50 years."

In addition to being an active boxer, Hopkins is also a minority partner with Golden Boy Promotions.

Born to Bernard Hopkins, Sr. and his wife Sue, Bernard grew up in the Raymond Rosen projects with his family. Hopkins turned to crime early in his life. By the age of thirteen he was mugging people and had been stabbed three times. At seventeen, Hopkins was sentenced to 18 years in Graterford Prison for nine felonies. While in prison he witnessed rapes and the murder of another inmate in an argument over a pack of cigarettes, but also discovered his passion for boxing. After serving almost five years, Hopkins was released from prison in 1988. He then decided to use boxing as an escape from his previous life, and converted to Islam. While leaving the prison for the final time, the warden told Hopkins he'd "see [Hopkins] again when you wind up back here," to which Hopkins replied "I ain't ever coming back here."

Pernell Whitaker (born January 2, 1964 in Norfolk, Virginia), nicknamed "Sweet Pea," is a professional boxing trainer and retired American professional boxer. Whitaker was the lightweight silver medalist at the 1982 World Championships, followed by the gold medalist at the 1983 Pan American Games and the 1984 Olympics. Whitaker then embarked on a pro career in which he became world champion in four different weight divisions. During his career, he fought world champions such as Julio César Chávez, Oscar De La Hoya and Félix Trinidad. For his achievements, he was named the 1989 Fighter of the year by Ring Magazine.

Whitaker is also a former WBA Light Middleweight Champion, WBC Welterweight Champion, IBF Light Welterweight Champion, WBC, WBA & IBF Lightweight Champion and NABF Lightweight Champion.

After his retirement, Whitaker returned into the world of boxing as a trainer. Among his trained boxers are Zab Judah, Dorin Spivey, Joel Julio and Calvin Brock. In 2002, Ring Magazine ranked him at number 10 in their list of 'The 100 Greatest Fighters of the Last 80 Years.' On December 7, 2006, Whitaker was inducted into the International Boxing Hall of Fame, in his first year of eligibility.
