#4 John Cena vs Brock Lesnar (Extreme Rules 2012)

It was in 2012 that Brock Lesnar returned to the WWE, amidst his battle with diverticulitis. Having retired from MMA at the time, Lesnar seemed focused on becoming the face of WWE—a storyline that was pushed heavily by WWE at the time.
Cena battled Lesnar in an Extreme Rules Match at the Extreme Rules PPV, and the matchup was thoroughly dominated by Lesnar, particularly in the early stages. Lesnar almost submitted Cena on the steel steps that were placed in the middle of the ring.

Nevertheless, Cena staged a comeback for the ages and dinged Lesnar with his signature “Thuganomics” metal chain—bloodying Lesnar up and eventually slaying the Beast. Cena and Lesnar’s Extreme Rules Match is widely considered to be one of the best pro-wrestling matchups of 2012 and earned widespread praise from both fans and experts alike.
