The Undertaker began his wrestling career in 1987 with the World Class Championship Wrestling (WCCW), where he won the WCWA Texas Heavyweight Championship with the character of The Punisher; in 1988 he moved to the Continental Wrestling Association (CWA), then known as the United States Wrestling Association (USWA), where he fought using several gimmicks and won the USWA Unified World Heavyweight Championship under the name of The Master of Pain.
After fighting for the World Championship Wrestling (WCW) as "Mean" Mark Callous from 1989 to 1990, he signed up for the then World Wrestling Federation (WWF) in 1990.
Undertaker on Hulk Hogan's injury
In an interview with ESPN, the Deadman discussed the much-talked-about incident at the 1991 WWE Survivor Series where Undertaker beat Hulk Hogan to win the WWE Title.
“That was crazy. It started out bad, and it progressively got worse. Hogan claims that I hurt him on the tombstone during the PPV. So I’m thinking to myself like I didn’t find out until Tuesday. I knew there was going to be another PPV, but I didn’t know I was going to drop the belt back, or what was going on.
That came up out of nowhere. But I kind of figured, oh, ok, maybe it’s because he’s telling everybody I hurt him, and ya know, Hulk was still the golden goose at the time. So I’m thinking, OK, they’re gonna take this off of me because they can’t trust me or whatnot.
It really wasn’t explained to me what the reasoning was behind it" - Taker recalled. Taker was one of the most prominent figures of the Attitude Era, a boom period in the company's business in the latter 1990s.
His character transitioned into a biker in the early 2000s, before returning to a refined version of his previous gimmick in 2004. The Undertaker is heavily associated with WWE's flagship annual event, WrestleMania, where he became known for The Streak, a series of 21 straight victories, and he headlined the event on five occasions.
