But there are some things that we still do not clearly know about him, especially his winning streak at Wrestlemania. Find out more below.
Before Undertaker was eventually beaten, he consecutively won 21 times at WrestleMania.
Undertaker's record is as glorious as Ric Flair's 16 whopping WWE championship titles record and the WWE championship dominance of Bruno Sammartino for 2803 days. Here are five facts you might want to know about his winning streak.
Undertaker's 23 wins at WrestleMania also include two victories coming after a loss, 16 of them have been won by pinfall after a Tombstone Piledrive was delivered.
Likewise, the Undertaker won two times by making his opponents submit after doing the Hell's Gate move. Another was through pinfall after giving King Kong Bundy a powerful clothesline. He won against Triple H by doing the Last Ride and against Mark Henry by using a casket.
Only Kane, the "Heartbreak Kid" Shawn Michaels, and Triple H have faced Undertaker more than once at WrestleMania.
Undertaker's first WrestleMania fight against Triple H was during WrestleMania 17 when he still had the role of being the American Badass. Triple H would be defeated by Undertaker both at WrestleMania 27 and WrestleMania 28.
Here, Undertaker was already in his Ministry of Darkness role. While fans loved his powerful moves, the hanging of Big Boss Man had an error that broke the brace to keep Big Boss Man. Undertaker's opponent had to be taken out using a stretcher after the first ever WrestleMania match that utilized the Hell in a Cell.
Undertaker fought Giant Gonzalez and the latter used a cloth with chloroform to weaken Undertaker. However, the referee noticed this and rightfully disqualified Giant Gonzalez.
Whenever Undertaker wins, you could see his "BSK Pride" tattoo on his front side. This means "Bone Street Krew" and that was the group of Undertaker during the 1990s.
Bone Street Krew included Paul Bearer, Savio Vega, the Godwinns, and the Godfather, who served as the balancing counterpart to the Kliq group that was composed of Triple H, Kevin Nash, Scott Hall, and Shawn Michaels.
