#8 Brock Lesnar
At WrestleMania 30, Brock Lesnar defeated The Undertaker to end his undefeated streak at the 'Showcase of the Immortals'.
It was a moment which shook professional wrestling and pop culture to its very core, and as such, WWE needed to do something big with 'The Beast Incarnate' moving forward.
He had to become an unstoppable monster - and he took another big step towards cementing his legacy at SummerSlam.
Not only did Lesnar defeat John Cena for the WWE World Heavyweight Championship, but he did so with ease. We've never seen Cena beaten like that before, in what was essentially a squash match.
Lesnar spent 95% of the bout completely dominating him, before finally putting the 16-time World Champion out of his misery with a monstrous F5.
