In terms of credentials, Brock Lesnar's are impeccable. As regularly highlighted by Paul Heyman, this is a man who has achieved plenty in the very real and competitive world of the NCAA and UFC. Lesner is as legit as they come and has a genuine nasty streak a mile wide at times. Brock's a guy that is just looking for an excuse to kick somebody's ass and would take great pleasure in doing so. Forget The Next Big Thing, the last few years have seen Brock take on the nickname of The Beast, and it could not be more apt. A unique physical specimen, Brock Lesnar is a no-nonsense ass-kicker who you feel could be quite capable of beating up anybody he so chooses on any given day. Whether it's breaking Bob Holly's neck, casually throwing the Big Show across the ring as if he was a cruiserweight, or decimating John Cena, Brock is right up there as one of the most intimidating performers on this list. Regardless of if he stays with the WWE after Wrestlemania 31, the addition of The Beast nickname over the last few years is the perfect natural fit for Brock and a stark reminder of who you are stepping into the ring with.
