Randal Barry Orton (born May 28, 1958 in Amarillo, Texas) is an American former professional wrestler. He is a wrestler/musician turned actor, better known as Barry O or Barrymore Barlow. He moved to Kansas City, Missouri with his mother and father three days after being born. He is the son of Bob Orton Sr. and Rita Orton, brother of "Cowboy" Bob Orton and Rhonda Orton, and the uncle of Randy Orton.

Orton made his pro wrestling debut in 1976. During his career in wrestling he competed in the WWF as "Barry O" (1984–1988, 1990–1991), ICW, WOW, the NWA, the IWF and Stampede Wrestling. While in Stampede, Orton appeared as the masked Zodiak (a gimmick first used by his father, loosely based on the Zodiac Killer), managing Jason the Terrible before feuding with him.

He was involved in a Phil Donahue show in 1992 when Phil discussed a WWF sex scandal. During the show, which also featured Vince McMahon and Bruno Sammartino, Barry spoke on telephone and revealed that, in his younger days in the wrestling business he was molested. He goes on to state that this did not occur in the WWF but he claims that those responsible later became two top officials in the WWF. Later in the show, Bruno Sammartino encouraged Barry to name the two people in question and Barry stated that the two men were Terry Garvin and Pat Patterson, both openly homosexual men. Orton has a son named Sir Christian Orton; born on April 11, 1991.

Randal Keith "Randy" Orton (born April 1, 1980) is an American professional wrestler and actor. He is signed to WWE wrestling on its SmackDown brand. Orton is a third-generation professional wrestler; his grandfather Bob Orton, Sr., father "Cowboy" Bob Orton, and uncle Barry O all competed in the professional wrestling industry.

Before being promoted to the main World Wrestling Federation (WWF, now WWE) roster, Orton trained in and wrestled for Mid-Missouri Wrestling Association-Southern Illinois Conference Wrestling for a month. He was then sent to Ohio Valley Wrestling (OVW), where Orton held the OVW Hardcore Championship on two separate occasions.

After signing with WWF, Orton became a member of the stable Evolution, which quickly led to a WWE Intercontinental Championship reign, his first title with the company. Orton also acquired the moniker "The Legend Killer" during a storyline where he began disrespecting Hall of Famers and physically attacking veterans of the industry outside of appropriate restrictions. At age 24, Orton became the youngest person ever to hold the World Heavyweight Championship. With this win, Orton departed from Evolution and a feud with his former stablemates began. In 2006, Orton joined forces with Edge in a tag team known as Rated-RKO. Together, Orton and Edge held the World Tag Team Championship. After the team disbanded, during mid-2007, Orton gained two WWE Championship reigns in one night. Orton formed the group The Legacy with Cody Rhodes and Ted DiBiase in 2008, however, they would disband in 2010 with Orton returning to singles competition. Overall, Orton has won eleven total championships in WWE, including being a nine-time world champion, having won the World Heavyweight Championship three times and the WWE Championship six times. He is also the winner of the 2009 Royal Rumble match.

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.
