#1 Brock Lesnar
And now for the best, the most powerfully dominant athlete to EVER step foot into the squared circle, Brock Lesnar. Standing over six feet tall and STRUGGLING to get down to the UFC's 265lb weight limit, he's already someone you don't want to mess with.
But wait, there's more!
Not only is he an All American amateur wrestler, Lesnar is also one of the most naturally gifted athletes ever to walk the face of the Earth. His power is obvious, but many opponents --such as the legendary Randy Couture -- have been taken aback by his unbelievable speed and agility.
So how tough is Lesnar? He once fell fifteen feet through the air and landed on his HEAD... and not only did he not die, he went on to finish the match!
Though Diverticulitis seems to have made the monster more of a man in recent years, there's still no question Brock Lesnar is the baddest 'Rassler of them all.
