Loser: John Cena1 of 5When John Cena announced his retirement tour, the promise was to deliver a memorable run to highlight his career and legacy before passing the torch. Brock Lesnar's arrival threatened the entire plan as The Beast Incarnate is someone Cena has always struggled to beat. Cena looked outmatched and overwhelmed competing with Lesnar, who squashed him as definitively as their SummerSlam 2014 clash. In the end, the GOAT was dominated, and the fans were left unsatisfied as the clock winds down on Cena's career. This will either lead to an unnecessary rematch or just leave Cena questioning what little he has left in his waning days in WWE.
