Steve Austin (born Steven James Anderson, later Steven James Williams; December 18, 1964), better known by his ring name "Stone Cold" Steve Austin, is an American film and television actor, producer, and retired professional wrestler. Austin wrestled for several well-known wrestling promotions such as World Championship Wrestling (WCW), Extreme Championship Wrestling (ECW) and most famously, the World Wrestling Federation (WWF). Described by WWE (formerly the WWF) chairman Vince McMahon as the most profitable wrestler in the company's history, he gained significant mainstream popularity in the WWF during the mid-to-late 1990s as "Stone Cold" Steve Austin, a disrespectful, beer-drinking antihero who routinely defied McMahon, his boss. This defiance was often shown by Austin flipping off McMahon and incapacitating him with the Stone Cold Stunner, his finishing move. McMahon inducted Austin into the WWE Hall of Fame in 2009.

Austin held twenty championships throughout his professional wrestling career, and is a six-time WWF Champion as well as the fifth Triple Crown Champion. He was also the winner of the 1996 King of the Ring tournament, as well as the 1997, 1998 and 2001 Royal Rumbles. He was forced to retire from in ring competition in early 2003 due to a series of knee and neck injuries sustained throughout his career. Throughout the rest of 2003 and 2004, he was featured as the Co-General Manager and "Sheriff" of Raw. Since 2005, he has continued to make occasional appearances. In 2011, Steve Austin returned to WWE to host the reality series Tough Enough.

Mark William Calaway (born March 24, 1965) is an American professional wrestler better known by his ring name The Undertaker. He is signed to WWE and is the company's most tenured competitor. Calaway began his wrestling career with World Class Championship Wrestling (WCCW) in 1984. He joined World Championship Wrestling (WCW) as "Mean" Mark Callous in 1989. When WCW did not renew Calaway's contract in 1990, he signed with the World Wrestling Federation in October and, after shortening his name from Kane the Undertaker to simply The Undertaker, has remained with the company since.

The Undertaker has two contrasting personas. The first is the role of The Deadman, an undead, occult-like figure, which has consisted of many different styles. He debuted his original Deadman persona during his own on-camera debut at Survivor Series (1990). At this event, the Undertaker was clad as a Western mortician. Next, in October of 1998, the Undertaker appeared as the leader of the Ministry of Darkness (with similar apparel). Since WrestleMania XX, the Undertaker has appeared as a hybrid version of the Deadman character, using elements of the previous Deadman incarnations.
