8. The Undertaker vs. Brock Lesnar, SummerSlam 2015

One of Brock Lesnar’s main limitations as a part-time star since his return to WWE in 2012 has been that he doesn’t necessarily come across as impassioned, so much as he is there to collect a paycheck. The one time he did come across as one hundred percent committed, and one hundred percent pissed off was during his summer 2015 program with The Undertaker.
Both major stars had an easy to understand beef. The Dead Man was upset that Lesnar had not only ended his WrestleMania undefeated streak but went on to brag about it for a year to follow. Meanwhile, Lesnar was justifiably infuriated that The Dead Man had interfered to cost him his opportunity to regain his WWE Championship from Seth Rollins.

The war of words and Monday Night Raw brawl between the two were electric, and their SummerSlam showdown paid off this issue nicely in an intense war. Moreover, there was a lot of intrigue packed into The Phenom’s willingness to fight dirty to ultimately beat Lesnar—including a phantom tap out and a low blow. The final image of Lesnar flipping of The Undertaker while succumbing to Hell’s Gate was a perfect finish, signalling that he didn’t respect his opponent and this war wasn’t finished.
