We all know The Undertaker as one of the greatest superstars in WWE history, but here are 10 things you might not know about "The Deadman".

He was managed by Paul Heyman in WCW

Prior to joining the WWE and becoming The Undertaker, Mark Calaway wrestled in WCW as “Mean Mark Callous.” He was also managed by a young Paul Heyman, then going by the name of “Paul E Dangerously.”

Debuted in WWE under a different name

In his official WWE debut, he was introduced as “Cain The Undertaker.” This was quickly dropped in time for his television debut the next week. The name would be revived and fittingly used for his brother, Kane.

He was a member of an off-screen group in the 1990s

The Undertaker was a member of the “Bone Street Krew” or BSK for short in the 1990s. Other members included Yokozuna, Rikishi, The Godfather and Paul Bearer. All group members had the letters BSK tattooed on them – which can be seen on the stomach of The Phenom.

Forced Vince McMahon to apologise to Bret Hart

Following The Montreal Screwjob, The Undertaker forced Vince McMahon to go to Bret Hart’s dressing room and apologise to him face to face. This led to The Hitman punching McMahon square in the face.

Was ready to fight Shawn Michaels at WrestleMania 14

At WrestleMania 14, Shawn Michaels was booked to drop the WWE title to Stone Cold Steve Austin before retiring due to a back injury. In expectation of HBK causing trouble, as he did back then, The Undertaker readied himself backstage. Luckily, nothing happened and the two went on to become close friends in later years.

Competed in the most Hell in a Cell matches

The Undertaker has competed in the most Hell in a Cell matches with 13. He competed in the first against Shawn Michaels and the most famous with Mick Foley. His record stands at eight wins and five losses – two of which came versus Brock Lesnar.

Himself and Triple H hold a joint-WrestleMania record

The two industry icons have competed against one another three times on the grandest stage of them all. This is a record they share with The Rock and Stone Cold, and Roman Reigns and Brock Lesnar. Their three bouts took place at WrestleMania 17, 27 and 28.

He has defeated all four members of Evolution at WrestleMania

As well as defeating Triple H three times at WrestleMania, The Deadman has also beaten Ric Flair (18), Randy Orton (21) and Batista (23) on the same stage. A clean sweep of Evolution, one of the best factions of all time, is a testament to his greatness.

He has never entered WrestleMania as Champion

Despite competing in a record 27 WrestleMania matches, The Undertaker has never entered as WWE or World Heavyweight Champion. This is perhaps due to the streak, and the lack of excitement if fans knew there would not even be a possible title change.

His favourite band is Metallica

The Undertaker has said that it depends on the day but his mainstay is Metallica, especially when training. To rubberstamp this, he entered his final match, the Boneyard contest with AJ Styles, to the sound of “Now That We’re Dead,” a song from the band’s 10th studio album.
