The Under taker

7. the Under taker

Mark William Calaway (born March 24, 1965)[6] is an American professional wrestler. He is signed to WWE, currently on its SmackDown brand roster. He is considered one of WWE’s senior competitors, having been with the company for twenty-one years. Mark 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 (which later became World Wrestling Entertainment in May 2002) as The Undertaker in November of that year and has remained with the company ever since.

The Undertaker has two contrasting gimmicks: “The Deadman”, an undead, occult-like figure, and “The American Bad Ass”, a biker. The specialty matches connected to The Undertaker are the Casket match, the Buried Alive match, the notorious Hell in a Cell, and the Last Ride match. The Undertaker’s kayfabe half-brother is Kane, with whom he has teamed as the Brothers of Destruction. The Undertaker is undefeated at WrestleMania with a 19–0 record. Among other accolades, he is a eight-time World Champion: a four-time WWF/E Champion and three-time World Heavyweight Champion as The Undertaker, and a one-time USWA Unified World Heavyweight Champion as Master of Pain. The Undertaker is also a one-time WWF Hardcore champion, and a seven-time world tag team champion: a six-time WWF Tag Team Champion, and one-time WCW Tag Team Champion. The Undertaker was the winner of the 2007 Royal Rumble and became the first man to enter the annual event at number thirty and win. He has been named by WWE as the greatest big man of all time,[9] the scariest superstar of all time and also the best pure striker in the history of the game.[10] Calaway is also the only active wrestler who appeared on the company’s very first Raw program, who remains with WWE today.

The Undertaker is the longest-tenured performer in WWE history, spending over twenty years with the company without officially leaving at any point (he is the last performer who appeared on the very first Monday Night Raw to still work for the company as an in-ring talent). Born Mark William Callaway, he is one of the most memorable and recognizable superstars in the company’s history.
His career — which you can read about in greater detail over at That Other Wiki  — is most notable for “The Streak”: in his nineteen appearances at WrestleMania, The Undertaker has never lost a single match, and every year since WrestleMania 17, “The Streak” is a huge part of the buildup to the annual event.
He and his kayfabe “half-brother” Kane are the last two holdovers from WWE’s “Rock ‘n’ Wrestling” era of high-concept, comic book-style wrestling gimmicks. Undertaker shed the “darkside” gimmick for a more true to Real Life one between 2000 and 2003, but he returned to it in 2004; even though an undead “zombie wrestler” with mystical powers sticks out like a sore thumb in today’s somewhat more realistic WWE, fans still adore his gimmick anyway.
When WWE crafted its controversial “50 Greatest Superstars of All Time” DVD set, the company polled its roster to create the list. Undertaker was #2 on the list — #1 was Shawn Michaels.
Not to be confused with The Coroner.
