Kevin Scott Nash is an American actor, podcaster and retired professional wrestler, currently signed to WWE under a legends contract. He is also known for his tenures with World Championship Wrestling (WCW) and Total Nonstop Action Wrestling (TNA).
Nash first gained exposure in the professional wrestling industry by performing for WCW from 1990–1993 under multiple ring names. In 1993, Nash signed with for the World Wrestling Federation (WWF, now WWE) under the name Diesel (nicknamed "Big Daddy Cool"). While performing as Diesel, he achieved status as a top star in the company, winning the WWF World, Intercontinental and Tag Team Championships (the WWF Triple Crown). His 358-day reign as WWF Champion is the longest of the 1990s. While in the WWF, Nash was part of The Kliq, an influential backstage group that included Shawn Michaels, Triple H, Scott Hall and Sean Waltman.
Nash left the WWF and returned to WCW in 1996, where he performed under his real name, partnering with Hall as the Outsiders and founding the New World Order (nWo) with Hulk Hogan. As the nWo storyline became one of the most prominent of the Monday Night Wars, Nash maintained his status as a top star, winning the WCW World Heavyweight Championship five times and the WCW World Tag Team Championship nine times. After WCW went out of business, Nash returned to the WWF in 2002, where he briefly reformed the nWo and feuded with Triple H over the World Heavyweight Championship. He then performed in TNA for seven years, and he held their Legends and Tag Team championships once each. In 2011, Nash returned to WWE under a legends contract and he continues to make sporadic appearances for the promotion.
During his in-ring career, Nash won 20 major championships, including six world championships and twelve world tag team championships. Furthermore, he is a two-time WWE Hall of Famer, as he was inducted individually into the class of 2015 and in 2020 as an nWo member alongside Hogan, Hall and Waltman.
