The case for Amanda Nunes
The greatest female fighter in history, 'The Lioness' is the first woman to hold two UFC titles simultaneously, reigning over both bantamweight and featherweight. She dismantled an entire generation of stars: a 48-second knockout of Ronda Rousey at UFC 207 in 2016, a 51-second knockout of the previously unbeaten Cris Cyborg at UFC 232 in 2018, plus wins over Miesha Tate, Holly Holm, Germaine de Randamie and two victories over Valentina Shevchenko. The only blemish in her prime was a shocking submission loss to Julianna Peña at UFC 269 in 2021, which she emphatically avenged with a one-sided decision at UFC 277 in 2022. She retired as the reigning double champion at 23-5, having beaten more current or former champions than any woman in the sport and settling the female GOAT debate for a generation.
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.
