Terry Gene Bollea (born August 11, 1953), better known by his ring name Hulk Hogan, is an American professional wrestler, actor, television personality, and musician signed to Total Nonstop Action Wrestling (TNA).

Hogan enjoyed mainstream popularity in the mid 1980s through the early 1990s as the all-American character Hulk Hogan in the World Wrestling Federation (WWF—now WWE), and was notable in the mid-to-late 1990s as Hollywood Hogan, the villainous nWo leader, in World Championship Wrestling (WCW). Following the closure of WCW, he made a brief return to WWE in the early 2000s before revising his heroic character by combining elements of his two most famous personas.

Hogan was later inducted into the WWE Hall of Fame in 2005. He is a 12-time world champion being a six-time WWF/WWE Champion, six-time WCW World Heavyweight Champion, as well as a former WWE World Tag Team Champion with Edge. He won the Royal Rumble in 1990 and 1991, making him the first to win two consecutive Royal Rumbles. He was also the first WWE wrestler to win the WWE Championship three times. In his first reign as WCW World Heavyweight Champion, Hogan held the title for 469 days from July 17, 1994 to October 29, 1995—the longest ever reign for this championship.

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.
