Mark William Calaway (born March 24, 1965), better known by his ring name The Undertaker, is an American professional wrestler and actor, currently signed to WWE. Calaway began his wrestling career with World Class Championship Wrestling (WCCW) in 1984. After wrestling for World Championship Wrestling (WCW) as “Mean Mark” Callous from 1989 to 1990, he signed with the World Wrestling Federation (WWF, now WWE) in 1990 and has remained since, making him the company’s longest tenured in-ring performer. Calaway is regarded as one of the greatest professional wrestlers of all time.
As The Undertaker, Calaway’s gimmick is a horror-themed, macabre entity who employs scare tactics and holds links to the supernatural; the character was reinvented as a biker during a period in the early 2000s before returning to his previous gimmick in 2004. The Undertaker is the storyline older half-brother of fellow WWE wrestler Kane, with whom he has alternately feuded and teamed with as The Brothers of Destruction. The Undertaker has been involved in various pivotal storylines and matches within WWE history.
The Undertaker is known for The Streak, an unprecedented run of 21 straight victories at WWE’s leading pay-per-view, WrestleMania (including main event bouts at WrestleMania 13, WrestleMania XXIV, and WrestleMania XXVI); he sustained his first loss at WrestleMania XXX to Brock Lesnar. Prior to his WWF/WWE career he also held the USWA Unified World Heavyweight Championship once and since unseating Hulk Hogan as WWF World Heavyweight Champion in 1991, he has won the WWF/WWE Championship four times and the WWE’s World Heavyweight Championship three times. He also won the 2007 Royal Rumble.
