Carmouche lost the first-ever UFC bantamweight title match in 2012 to Ronda Rousey, who went on to become one of the biggest names in the sport, but Nunes ended Rousey's career with a brutal 48-second knockout in December 2016. Having won the bantamweight title by defeating Miesha Tate in July of that year, Nunes added the featherweight strap with a superb 51-second knockout of feared fellow Brazilian Cris Cyborg in December 2018 to become a simultaneous two-weight champion.
