His name was Diesel. Being a feared opponent, Kevin Nash was immensly feared in and outside the ring. Don't be fooled by the big man's size, he is very quick and agile. Diesel soon broke away from Shawn Michael's side and adventured on his own very successful solo career, that included winning the Intercontinental and World Wrestling Federation Heayweight Titles. He fought many great wrestlers while in the WWF, including Bret Hart, Owen Hart, The Undertaker, Shawn Michaels, The British Bulldog, and many others.

When his contract expired in early-1996, Kevin was offered a lucrative contract by the WWF's main competitor, WCW, and signed with them, along with close friend Scott Hall. The two formed "The Outsiders." It did not take too long for Nash to make an impact there, first joining "Hollywood" Hulk Hogan to form the nWo Black & White. A couple of years later, Nash, along with Lex Luger, Sting, and others, split away from Hogan and the nWo Black & White, and formed the nWo "Wolfpack," also referred to as the nWo Red & Black. Nash is often noted as being the first wrestler to ever defeat Bill Goldberg, thereby ending Goldberg's long-running winning streak.

Nash returned to WWE television in February of 2002 when Vince McMahon announced he was going to inject a lethal dose of poision into his own federation - the nWo. After a short stint as an nWo member, Nash went solo again and then back to long-time buddy Shawn Michaels.

During his last stint with the WWE, he wrestled against real-life friend Triple H in a 'Hell in a Cell' match for the World Heavyweight Championship at the June PPV, Bad Blood 2003. Although he lost, many considered this to be his best match in the WWE.

Nash's contract with the WWE expired in January 2004 and he decided not to re-sign with the company.

In October 2004, Nash and Scott Hall signed a contract with TNA wrestling. They are currently teamed up with Jeff Jarrett, and they call themselves the 'Kings of Wrestling'.
