10. The Undertaker Vs Brock Lesnar (WrestleMania XXX, SummerSlam 2015, Hell In A Cell 2015)

Brock Lesnar and The Undertaker had an amazing Hell in a Cell match back in 2002, but when Lesnar came back to WWE as a former UFC Heavyweight Champion, a bout with Undertaker - at WrestleMania, no less - had entirely different implications. The two men fought at WrestleMania XXX, with Brock scoring the most shocking win since Ivan Koloff beat Bruno Sammartino.

The match left something to be desired, as Undertaker suffered a serious concussion in the early goings and couldn't perform properly. Many assumed this would be his swan song, a fading-away after a sad contest. He continued to compete, though, and eventually challenged Brock to a bout at SummerSlam 2015. This time, the two men had the match they were destined to have - a hard-hitting affair with Lesnar throwing suplexes and The Phenom defying nature to battle back.

Undertaker won the SummerSlam match under the most controversial of circumstances (he choked Brock out with Hell's Gate after "The Beast" forced him to submit to a Kimura, but referee Charles Robinson didn't see the submission), setting up a rubber match at the Hell in a Cell Pay-Per-View. The two men clashed in the steel structure, with blood and suplexes the order of the day. 

Finally, Lesnar tore up the ring canvas and planted Undertaker with an F5 on the exposed dasher boards to pick up a decisive win.
