Steve Borden, better known by the ring name Sting, is an American professional wrestler and former bodybuilder, currently signed to All Elite Wrestling (AEW) as the mentor of Darby Allin. He is regarded as one of the greatest professional wrestlers of all time, having cultivated a legacy over a career spanning five decades. Throughout his career, he won a total of fifteen world championships. Sting is widely known for his time spent as the public face of two major American professional wrestling promotions: the now-defunct World Championship Wrestling (WCW), which was bought by the WWE in 2001, and Total Nonstop Action Wrestling (TNA, now Impact Wrestling). Although the WWF had purchased WCW, Sting did not sign with them at that time. Prior to WCW, he also wrestled for the National Wrestling Alliance (NWA), the Universal Wrestling Federation (UWF), and Mid South. Sting's 14-year association with WCW and its predecessor, Jim Crockett Promotions (JCP), began in 1987. He quickly rose to main event status and has been described as the WCW counterpart to the WWF's Hulk Hogan. Dubbed "The Franchise of WCW", he held a total of 14 championships in the promotion – including the WCW World Heavyweight Championship on six occasions, the WCW International World Heavyweight Championship on two occasions, and the NWA World Heavyweight Championship on one occasion – and made more pay-per-view (PPV) appearances for the company than any other wrestler. Against Hogan, Sting headlined the highest-grossing PPV event in WCW history, Starrcade, in December 1997. Upon the acquisition of WCW by the WWF in March 2001, Sting and his long-term rival Ric Flair were chosen to perform in the main event of the final episode of Nitro. Sting would later face Hogan and Flair in their last televised matches, defeating both. Following the expiration of his contract with WCW's parent company, AOL Time Warner, in March 2002, Borden held talks with the WWF, but ultimately did not join the promotion and instead toured internationally with World Wrestling All-Stars (WWA) – winning the WWA World Heavyweight Championship – before joining the then-upstart TNA in 2003. Over the following 11 years, he won the NWA World Heavyweight Championship on one further occasion and the TNA World Heavyweight Championship four times. As a result, he became the only wrestler to have won the NWA, WCW, and TNA World Titles in a career. He was also the inaugural inductee into the TNA Hall of Fame in 2012.
