#1. Brock Lesnar's streak ends this year at SummerSlam
Brock Lesnar has been the most dominant star in WWE ever since his return in 2012 and no one has ruled SummerSlam like The Beast Incarnate. Over the past six years, Brock Lesnar has main evented every SummerSlam pay-per-view, starting with his win over John Cena back in 2014.
Lesnar was then defeated by The Undertaker in 2015, was able to defeat Randy Orton by Technical Knockout in 2016, and Braun Strowman, Roman Reigns, and Samoa Joe were on the losing end of a Fatal 4-Way for the Universal Championship against Brock Lesnar the following year.
Roman Reigns was finally able to defeat Brock Lesnar for the Universal Championship in 2018's main event. And Seth Rollins defeated The Beast in SummerSlam's main event last year to become a two-time Universal Champion.
This year, Brock Lesnar hasn't returned to WWE since he lost the WWE Championship to Drew McIntyre at WrestleMania and won't be part of the show. This means that for the first time since 2014 someone other than Brock Lesnar will main event at The Biggest Party of the Summer.
