For my money Fedor Emelianenko is the best fighter that has ever lived, that’s of any discipline. If you threw two guys out on the street for a battle to the death I’d take Fedor at his peak vs anyone. He was 31-1 at one point and the one fight was a doctor stoppage for a cut. He never fought in the UFC, but he dismantled several former champions and won many impressive fights vs quality fighters of his era and freaks of nature. His emotionless stare is probably the best I have ever seen. He just problem-solved in the fight like a mathematician would in class. With the same demeanor no matter how much trouble he was in. It was impressive to follow in those years. Fedor didn’t walk into the arena shredded, he walked in looking like your average UPS driver or guy sitting at the end of the bar or Joe in accounting adding to the legend. When he was young he still looked middle-aged. Dana White once called him the chubby bald guy, and he pretty much was in a world of shredded abs. He’s also probably the greatest fighter that has ever lived.
