DALLAS: Amanda Nunes defeated Julianna Pena by the decision to reclaim her bantamweight title at UFC 277.
The 34-year-old Brazilian successfully avenged her shocking defeat to the American in December by dominating both stand-up and grappling.
Nunes, who also owns the featherweight belt, beat the 32-year-old, making him the first two-time double champion in UFC history.
"We make history again, this is the best day in my life," said Nunes.
In the co-main event, Brandon Moreno defeated Kai Kara-France with a brutal body kick in the third round to win the interim flyweight title.
Deiveson Figueiredo, the champion of the division, joined Moreno in the cage after the fight, and they mutually decided to have an unprecedented fourth fight for the undisputed championship.
In one of the biggest upsets in UFC history, Pena famously submitted Nunes in Las Vegas seven months prior, snapping her 12-fight winning run and winning the belt.
In a streak that saw the "Lioness" defeat several current and former champions, including Ronda Rousey, Cris Cyborg, and Valentina Shevchenko twice, this was Nunes' first loss in seven years.
