Kevin Scott Nash is a professional wrestler from Detroit, Michigan. He went to the University of Tennessee, where he played center for the Tennessee Volunteers basketball team.
WCW, Part 1
Nash began his career in WCW as one half of the "Master Blasters" tag team. Eventually this was dropped and he was re-introduced as "Oz," a character based on the Wizard of Oz (no seriously, have you ever watched early 90's WCW?). In 1992 he became "Vinnie Vegas," a pseudo-mobster character. Then he partnered with Diamond Dallas Page to form a team called "The Vegas Connection."
WWF, Part 1
In 1993 Nash left WCW to head to what was then the World Wrestling Federation. He would wrestle there as "Diesel," bodyguard to Shawn Michaels. This would continue until the two split up and Diesel defeated Bob Backlund for the WWF Title in under ten seconds in November of that year. He would feud with Michaels over his title until Wrestlemania XI, where he defeated him to retain the belt. Afterwards he and Michaels reunited to feud with Michaels' new bodyguard, Sid Vicious. He held the title until November of 1995, feuding with the likes of King Mabel and Bret Hart, nearly bankrupting the WWF in the process. After holding the title for nearly a year he lost it to Hart at Survivor Series. He then feuded with the Undertaker until Wrestlemania XII, where he became a victim of Undertaker's undefeated streak at the event. Afterwards he signed a contract with WCW and left in the Spring of 1996, infamously group-hugging Michaels, the also-leaving Scott Hall, and Hunter Hearst Helmsley after their final house show match at Madison Square Garden, then considered a grievous breach of character.
WCW, Part 2
Nash reappeared in WCW as part of "The Outsiders," a tag team consisting of him and fellow ex-WWF wrestler Scott Hall. The two would beat up random WCW wrestlers whenever they felt like it and eventually promised that a third wrestler would join them. At Bash at the Beach '96, this third man turned out to be none other than ex-WWF Champion Hulk Hogan, who had been in WCW for around two years at the time. Together they formed an alliance dubbed "The New World Order" and continued beating up random WCW wrestlers. The Outsiders would hold the tag titles for most of 1996 and 1997, feuding with other teams like the Steiner Brothers and Harlem Heat. Eventually Nash turned on Hogan and left the NWO to form his own NWO splinter group, the "NWO Wolfpac." He would team with Sting, who had feuded with Hogan over the WCW Title for most of 1997. They feuded with Hall and The Giant over the WCW Tag Belts. Eventually he entered a singles feud with Hall, which resulted in him losing a match against Hall in a count-out.
Nash earned the right to a title shot against Bill Goldberg at the World War 3 Pay-Per-View. He would end Goldberg's undefeated streak at Starrcade when Scott Hall surprised Goldberg by tasering him, allowing Nash to pin him for the title. Nash was supposed to face Goldberg in their first rematch on an episode of WCW Monday Nitro on January 4th of 1999. However, Goldberg was arrested for "stalking" manager Miss Elizabeth, and was held at a Police Station until they figured out that she was not telling the truth. Goldberg was released from police custody an hour before the match was to take place. However, despite the police station being directly across the street from the Georgia Dome, where the show was taking place, Goldberg failed to make it back in time. In the meantime Nash challenged the recently "retired" Hollywood Hulk Hogan to a match for the title. When the match began, Hogan pulled his arm back and then lightly tapped Nash in the chest with his index finger. Nash fell down and allowed Hogan to pin him to regain the title. Then both NWO groups reunited and beat up Goldberg, who had finally made it back to the arena. This infamous event became known as the "Fingerpoke of Doom" incident, marked as a point when the company began its irreversible downward slide and made all the more harmful by WCW's attempt to mock the WWF by announcing that wrestler Mick Foley would be winning the WWF's World Heavyweight Championship as Mankind on a taped episode of Monday Night RAW that same evening.
Nash would later defeat Rey Mysterio for his mask at SuperBrawl '99 and feud with Hogan and other WCW wrestlers after the NWO dissolved in 1999. He and Hall would eventually reform the NWO, however this new version fizzled as he himself was injured and new member Bret Hart suffered what would turn out to be a career-ending concussion. He would go on to feud with wrestlers like Booker T over the WCW Title until losing a "retirement match" to Scott Steiner in 2000. Eventually WCW was sold to WWF owner Vince McMahon, and Nash choose to wait out his contract with AOL-Time Warner until it ended at the end of 2001.
WWF, Part 2
Nash returned to the WWF in 2002 along with Hall and Hogan to reform the NWO one last time. Eventually he and Hall turned on Hogan, who returned to his old "Real American" persona. Nash suffered a biceps injury and missed a few weeks of time. Upon his return, he immediately managed to tear his quadriceps while walking across the ring in his very first match back. He would not return from this injury until April of 2003. When he returned he feuded with Triple H over the WWF World Heavyweight Championship. He then filmed the movie "The Punisher" and wrestled his final WWF/WWE match in November 2003. He left the company a second time when his contract was not renewed in January of 2004.
From 2004 to 2010 Nash wrestled for NWA-TNA wrestling. His early days with the company he teamed with old partner Scott Hall and Jeff Jarret, dubbing themselves the Kings of Wrestling. In April 24th, 2005, Nash was booked in a six man tag team match with old WCW alumni Sean "Syxx" Waltman and Diamond Dallas Page, but unfortunately was afflicted with a staph infection that left him sidelined for the remainder of the year. Nash to TNA in 2006, and this tenure was notable for his affiliation with the stable the Main Event Mafia. The Main Event Mafia was composed of several veteran pro wrestlers known for winning major titles in wrestling. Also notable was Nash reforming a stable intending to be a spiritual successor to the NWO, called the Band. The group consisted of Nash, Scott Hall, and Sean Waltman. This group eventually disintegrated due to the personal issues of Scott Hall and quietly dissolved. Nash's final appearance on TNA programming consisted of an angle were Sting and Nash reject joining the new Super Heel Faction 'Immortal'. While Sting eventually resigned with the company, Kevin Nash left for another tenure in the WWE.

After a brief hiatus Nash returned at the 2011 Summerslam, attacking CM Punk and engaging in a brief feud. Eventually Nash moved on to a feud with fellow 'Kliq' member Triple H.
