At this year's SummerSlam event, Brock Lesnar was successful in defeating (and decimating) John Cena for his fourth WWE World Heavyweight Championship. Of course, there was some doubt going into the bout regarding whether Lesnar would emerge victorious, but looking back at his win-loss record, there really shouldn't have been. Dating back to his debut the night after WrestleMania 18, Lesnar has asserted his dominance over everyone who has stepped foot in his path of destruction over the last 12 years, racking up only a handful of loss in singles competition. Taking his previous stint with the company into account, Lesnar has been defeated via pinfall and submission only eight times in his WWE career. Granted, the fact he took an eight year hiatus from WWE may make that statistic less impressive, but there's no doubting that he has been well protected over the course of his career. Only elite few can say they've slayed the beast, so that's an accomplishment in of itself. That said, this list will cover the 10 Superstars to beat Lesnar in singles competition (albeit pinfall or submission) or in tag team matches where he was the one pinned or submitted. Will anyone be able to put an end to The Conqueror's reign of terror?
