Facing our number seventh best in-ring worker for 21 straight Wrestlemania events meant he would "Rest In Peace" that night.  The Undertaker dominated and defeated 21 consecutive opponents at the World Wrestling Federation/Entertainment's premiere event before finally losing at Wrestlemania to Brock Lesnar at Wrestlemania 30.  On top of the record-breaking streak, he is a four-time WWF/E Champion and a three-time World Heavyweight Champion.

Even before he made his WWF/E debut in 1990, Mark Calaway has always an amazing in-ring talent that is unheard of for someone of his height (6'10").  From defeating Hulk Hogan in 1991 for his first WWF title, to his reign over the Ministry of Darkness, and even in his first Wrestlemania defeat, the Undertaker has entertainment millions of fans with some of the best matches ever seen for the last 25 years.

No other "Big Man" has shown the innate to not only climb to the top turnbuckle but also walk on the top rope whenever he goes "Old School."  Easily the best matches the Undertaker was involved in were against  his biggest rival Shawn Micheals.  He was involved in the first-ever Hell in a Cell match-- still the best one to have taken place-- with the Heartbreak Kid.  They matched up in the first-ever Casket match (another classic).  At Wrestlemania 25 and 26,  the Phenom and Michae took each other in two of the greatest matches in Wrestlemania, and possibly professional wrestling, history.

Along with Triple H, no other Superstars have been involved in as many Hell in a Cell matches.  While the first one may be the best of them all, his Hell in a Cell match with Mankind is easily the most famous.  No matter if he enters the ring led by a host of druids or he comes down in a chopper as the American Badass, the Undertaker has never failed to tell an amazing story inside the squared circle.

Speaking of Triple H, no other man has faced the Deadman more times at Wrestlemania-- they have faced off three times.  In the third meeting, they faced in an End of an Era Hell in a Cell match-- a match that stole the spotlight of Wrestlemania 28.  Throughout 30-year career (25 in WWF/E), the Undertaker has gone down in history not only as one of the greatest superstars of all-time, but also one the greatest in-ring tactians in sports entertainment history.
