5 legends the WWE Universe will pop for on the 25th anniversary of Raw

#4 The Undertaker

The Undertaker is expected to face Cena at Wrestlemania

The Undertaker is the most respected WWE superstar of all time. He has an impressive 21 straight Wrestlemania victories. "The Dead Man" is also a four-time WWE champion and winner of the 2007 Royal Rumble match. He is the longest-tenured in-ring performer in the history of the WWE. A year after making his debut, he defeated Hulk Hogan to win the WWE championship at Survivor Series in 1991.

A poll by Digital Spy voted The Undertaker as the greatest WWE wrestler ever in 2013. He last competed in the ring at Wrestlemania 33 where he suffered a loss to Roman Reigns. However, he is set to make an appearance at the 25th anniversary of Raw scheduled to take place in January 2018 and pundits believe he is going to confront John Cena for one final dance at the grandest stage. The WWE universe will welcome back The Undertaker with a loud pop this Monday night.
