Mark William Calaway, better known by his ring name The Undertaker, is a retired American professional wrestler. He is currently signed to the promotion WWE, where he has worked since 1990, making him WWE's longest-tenured performer. Calaway began his wrestling career with World Class Championship Wrestling in 1984. After wrestling for World Championship Wrestling as "Mean" Mark Callous from 1989 to 1990, he signed with the World Wrestling Federation in 1990. As The Undertaker, his gimmick is that of a macabre entity who employs scare tactics and has links to the supernatural. He is the storyline half-brother of fellow WWE wrestler Kane, with whom he has alternately feuded and teamed with as The Brothers of Destruction. Since unseating Hulk Hogan as WWF Champion in 1991, The Undertaker has been involved in various pivotal storylines and matches within WWE history. The Undertaker holds a record 21 straight victories at WWE's annual WrestleMania pay-per-view, sustaining his first loss at WrestleMania XXX to Brock Lesnar, and was the winner of the 2007 Royal Rumble.
