7. Brock Lesnar's Revenge
WWE.comDespite the beat-down Lesnar delivered at Extreme Rules 2012, Cena was victorious (he overcame the odds) again. Heyman will stress that despite beating the Undertaker and Triple H, his client will want to take out the best, and take the title. Two plus years of frustration will be taken out on Cena at their Summerslam encounter. Lesnar dominated the entire contest and left Cena bloodied and battered. To get this point across, Lesnar will take out random superstars along the way, much like when he destroyed Spike Dudley and Al Snow in his television debut in 2002. Lesnar will be going into Summerslam full steam ahead ready to take out the man who pinned him two years ago, starting the Summer of Brock and his fourth WWE title reign.
