The case for Fedor Emelianenko
'The Last Emperor' was the consensus best heavyweight in the world through the mid-2000s and the defining icon of Japan's PRIDE era. A master of combat sambo, he combined unorthodox looping punches with slick submissions and an unshakable calm, going undefeated for nearly a decade — a run of 28 fights without a legitimate loss from 2000 to 2010. As PRIDE heavyweight champion he beat Antonio Rodrigo Nogueira, Mirko Cro Cop, Mark Coleman and a young Andrei Arlovski, whom he stopped with a flying-punch knockout. He never competed in the UFC, which fuels endless debate about his placement, and his level of competition in some later fights is questioned. But at his peak, against the best heavyweights alive, he was untouchable, and he retired around 40-7 as one of the most beloved and mythologized figures the sport has produced.
The case for Kamaru Usman
'The Nigerian Nightmare' built one of the most dominant welterweight reigns in history on a base of relentless, high-level wrestling that evolved into genuine knockout power. He put together a 15-fight UFC winning streak — among the longest ever — and won the welterweight title from Tyron Woodley at UFC 235 in 2019, then defended it five times. He beat Colby Covington twice in grueling wars, avenged an early loss to Jorge Masvidal with a highlight-reel knockout, and outpointed Gilbert Burns and Leon Edwards. His reign ended dramatically when Edwards landed a head kick with under a minute left in their UFC 278 rematch in 2022, erasing a fight Usman was winning. He sits around 20-4, a wrestler who became a finisher and headlined the sport's African golden age alongside Israel Adesanya and Francis Ngannou.
