Debut and WWF Championship (1990–1991)

Calaway made his WWF debut as "Cain the Undertaker" at WWF Survivor Series on November 19, 1990. Approximately one minute into the match, Undertaker eliminated [[Koko B. Ware]] with his signature maneuver, the Tombstone Piledriver. He also eliminated [[Dusty Rhodes]] before being counted out. Shortly after Survivor Series, "Cain" was dropped from his name, and he was called simply The Undertaker. The appearance of Undertaker was modeled after a mortician from old Western movies, with the gimmick that he was impervious to pain and possessed supernatural powers, such as teleportation and manipulation of flames and lightning. It was at this time that the Undertaker switched managers from Brother Love to [[Percy Pringle|Paul Bearer]]. He made his [[WrestleMania]] debut at [[WrestleMania VII]], squashing [[Jimmy Snuka|"Superfly" Jimmy Snuka]]. The win was the first in his undefeated streak at the event. After a year of battles with the [[Ultimate Warrior]] in body bag matches, [[Randy Savage]], and [[Hulk Hogan]], he defeated Hogan to win his first [[WWE Championship|WWF Championship]] at [[Survivor Series]]. WWF President Jack Tunney ordered a rematch for This Tuesday in Texas six days later, where Undertaker dropped the title back to Hogan.
