The Undertaker's story starts off in hell. He fights for the devil's amusement. He is the future ruler of Stygain, hell's prison. At first he only possesses the third volume of the book of the dead. In order to rule Stygain he must obtain all three volumes, But in order to do this he must kill the Embalmer and his step-father Paul Bearer. Paul Bearer was easy enough to dispose off. He has his servant Lotan, a werewolf type demon, sniff him out. When the two come to Paul Bearer's dwelling Lotan betrays the Undertaker and attacks him. Little to Paul, Lotan, or the Undertaker's knowledge The Undertaker's half-brother,Kane, and half-sister Jezebelle, were there. Kane doesn't say much. He is the muscle of the two. He killed Lotan quickly and then blasted Paul Bearer out of a window using his ability to manipulate fire. This allows The Undertaker to take the First volume of the book of the dead, but he was still missing the crucial Second book. The Second volume of the Book of the Dead was in the hands of a man who broke into Stygain and freed demons inorder for his bidding. This man was the Embalmer. He had many of his demons in the World Wrestling Federation, where Kane was also in. The Embalmer possesed the ability of manipulating flames aswell which is how he originally escaped the Undertaker. Undertaker was shot in the back after killing a dozen demons and fell out of the window of the Embalmer's scyscraper. The Deadman holds the Books that show the Past and the Future, But lacks the Present. This is why the Embalmer is so dangerous.
The Undertaker is also known as the Deadman. When wrestling, he is usually billed as coming from Death Valley, and he has traditionally been one of the most dominant forces in the WWE. The Undertaker debuted at the WWE's Survivor Series pay-per-view in 1990 in a match that also featured Bret "The Hitman" Hart and Jim "The Anvil" Neidhart. The Undertaker has gone on to establish a prestigious winning streak, as well--he has yet to be defeated at WrestleMania. The Undertaker's career has been unmatched since his debut. Probably one of the most memorable matches in the Deadman's illustrious career was the Hell in a Cell match of 1999. The Undertaker was set to meet Mankind (Mick Foley) inside the sadistic structure, but mankind decided to start the match at the top of the structure. When Mankind tried to attack the deadman he missed and fell nearly 20ft from the top of the cell. After mankind got back up (now with a broken arm) both men climbed the structure again. Mankind again slipped up and the phenom choke slammed him through the roof of the cell and down 15ft to the mat.Mercifully the match ended just minutes later after a tombstone piledriver. After the match
walked away with one tooth missing and a whole in his bottom lip. The Phenom picked up his first victory inside the cell that night.
Undertaker is still undefeated at Wrestlemania.
The streak started at Wrestlemania 7 where he wrestled and defeated Jimmy 'Superfly' Snuka. It continued at Wrestlemania 8 where he defeated Jake 'The Snake' Roberts.
He has increased his undefeated streak to 18-0 with his defeat of Shawn Michaels at Wrestlemania XXVI. Due to the stipulation of the match Shawn Michaels was forced to retire as a result of the loss.
The following year Triple H challenged the Undertaker to avenge his friends loss. However, Triple H failed to beat the Undertaker and the streak moved to 19-0.
At Wrestlemania 28 Triple H once again challenged the Undertaker at a match in Wrestlemania. This time it was a Hell in the Cell match with Shawn Michaels as a special guest referee. Even with the odds slightly in Triple H's favor he still lost the match and the Undertaker moved to 20-0.
This year at Wrestlemania CM Punk Challenged the Undertaker. During the build up to the match, CM Punk had stolen the Undertaker's Urn which is supposed to be the source of the Undertaker's powers. However, this did not make a difference as Punk still lost and the Undertaker moved to 21-0.
At One Night Stand Edge did the unthinkable with a little help from his "La Familia". Just weeks before the PPV Smackdown GM Vickie Guerrero decided that if the Undertaker lost the TLC match then he was to be banished from all of the WWE. one Night Stand La Familia interfered giving Edge the upper hand in the match. The Undertaker managed to over come though and beat Edge to a pulp. It wasn't enough though. The Undertaker was just inches away from victory when Edge mustered the strength to push the ladder over sending the phenom down 15 feet and through a table. Edge climbed the ladder and grabbed the World Heavyweight Championship to pick up a win and banish the Undertaker. After Edges act of adultery Vickie Guerrero reinstated the Undertaker and put Edge and the Phenom inside Hell in a Cell at the biggest blockbuster of the year Summer Slam. WIll the Phenom get his vengence or will the Ultimate Opportunist get the upper hand once more? Only Sunday August 17th 2008 will tell.
