Brock Lesnar will always be known as the man who ended The Undertaker's undefeated streak at WrestleMania. Although both men are on good terms right now, they weren't several years ago.

When The Beast Incarnate's first WWE run ended in 2004, things didn't end in the best way possible for all parties involved. Some fans believed at the time that there was a lot of animosity between Undertaker and Lesnar after the former MMA fighter left WWE.

Several years later at UFC 121, Lesnar and Undertaker had a small confrontation after The Beast Incarnate lost the UFC Heavyweight Championship to Cain Velasquez. The Undertaker has implied that he was sent there personally to spark interest in a future WWE match against Lesnar.

In an interview with UFC's Ariel Helwani from 2011, Lesnar stated that he had real-life beef with The Undertaker.

"You know, I was a bit delirious. Obviously, Cain (Velasquez) put me on a street that I didn’t know the name of and I was looking for my way home. So I went out of the Octagon and I had heard that The Undertaker was going to be there. Once again, I enjoyed working with Mark [Undertaker] in the ring but me and him...Well, there were some things said that kinda really pi**ed me off."

Although the tension between the two WWE Superstars never got too personal, it's hard to say how much of they amplified their beef for the sake of kayfabe, and how much of it was actually real.

Eventually, the stars aligned for a Brock Lesnar vs. The Undertaker matchup at WrestleMania 30. Both men have mutual respect today.
