The case for Demetrious Johnson
'Mighty Mouse' is arguably the most technically complete fighter of all time, a flyweight who mastered every phase without a defining weakness. As the inaugural UFC flyweight champion he set the record for most consecutive title defenses with 11, a run of dominance from 2013 to 2018 in which he blended world-class striking, wrestling and submissions into a seamless whole. His suplex directly into an armbar against Ray Borg at UFC 216 in 2017 is one of the most spectacular finishes in history. Because he competed in the sport's lightest and least-promoted division, his brilliance was often underappreciated relative to bigger names. Traded to ONE Championship in 2018, he won that promotion's flyweight grand prix and title and delivered a flying-knee knockout of Adriano Moraes in 2022. He retired around 25-4-1, revered by peers as a fighter's fighter and a technician without equal.
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.
