#2 Brock Lesnar Vs The Undertaker

Brock Lesnar breaks the Undertaker's undefeated streak

In 2014, Brock Lesner did the unthinkable, he broke The Undertaker's undefeated streak at Wrestlemania 30. Everyone was shocked, they couldn't believe their eyes but that actually happened. Undertaker for the first time in his 24 year career was pinned at WrestleMania.

After that Lesnar went on to become the most dominant force in WWE, he beat John Cena at Summerslam for the WWE World Heavyweight Title and lost it at Wrestlemania 31 when Seth Rollins cashed in his money in the back contract. Lesnar got his one on one rematch with Rollins at Battleground 2015 and that's when the deadman showed up. Undertaker waited 15 months to get his revenge on Lesnar, he straight up low blow Lesnar, which made it clear that how far he is willing to go to get his revenge.

The biggest rematch was set for SummerSlam 2015, where both the stars beat the hell out of each other, but at the end, Undertaker walked out with a controversial victory. Taker actually tapped up to Lesnar in that match but the referee didn't see that and at the end, his hands were raised. The ending of the match is iconic, Lesnar thought he won the match after the timekeeper ring the bell, but the referee didn't call for it.

Taker low blew him and trapped him in the hell's gate. Lesnar refused to tap out and passed out showing the middle finger to the Undertaker. The final chapter was the Hell in a Cell match, where both the superstars were in blood, they even exposed the ring. Lesnar finally beat Undertaker after giving him an F5 in the exposed ring and ended their storied rivalry.
