Which entity is this text about?

Nash was born on July 9, 1959, to a devout Christian family, in southwest Detroit, Michigan. Nash's father, Robert, died of a heart attack on April 4, 1968, aged 36, when Nash was eight years old. On December 27, 1994, Nash's mother, Wanda, died after a four-year struggle against breast cancer. He attended Aquinas High School, followed by the University of Tennessee, where he majored in psychology and minored in educational philosophy.

Nash debuted in Total Nonstop Action Wrestling alongside the returning Scott Hall on November 7, 2004 at the inaugural monthly TNA pay-per-view, Victory Road, with the duo helping NWA World Heavyweight Champion Jeff Jarrett retain his title in a ladder match with Jeff Hardy. In subsequent weeks, the trio identified themselves as the Kings of Wrestling and began feuding with Hardy and A.J. Styles. At Turning Point on December 5, the Kings of Wrestling were defeated by Hardy, Styles, and Randy Savage.  Hall left TNA in early 2005, and Nash and Jarrett separated after Nash made clear his desire to win the NWA World Heavyweight Championship. Nash received a title shot against Jarrett on February 13, 2005 at Against All Odds, but lost following interference from the debuting Outlaw. Following the defeat, Nash joined forces with Sean Waltman and began feuding with the newly formed Planet Jarrett. At Destination X on March 13, Nash lost to The Outlaw in a First Blood match following interference from Jarrett, who struck Nash with his title belt. The rivalry between Planet Jarrett and Nash and his allies culminated in a scheduled Lethal Lockdown match at Lockdown on April 24 pitting Nash, Waltman, and Diamond Dallas Page against Jarrett, The Outlaw, and "The Alpha Male" Monty Brown. Nash, however, was removed from the card and replaced with B.G. James after contracting a staph infection, which left him sidelined for much of 2005.  Nash returned to TNA on October 1 for the first episode of Impact! on Spike TV, attacking and powerbombing Jarrett. Nash went on to challenge Jarrett to a match for the NWA World Heavyweight Championship at Bound for Glory on October 23. In the weeks preceding the event, Nash and Jarrett had several heated confrontations, on one occasion brawling with one another and with guest referee Tito Ortiz. On October 22, one day before Bound for Glory, Nash was hospitalized with chest pains. At Bound for Glory, a battle royal was held to determine the number one contender; Rhino won and then defeated Jarrett for the NWA World Heavyweight Championship. Nash was later discharged from the hospital, having suffered a mild cardiac episode. He made a partial return to the ring in December 2005, wrestling several matches on a tour of South Africa.
