In addition to Anderson, Nunes has defeated six former UFC champions in Ronda Rousey, Holly Holm, Miesha Tate, Germaine de Randamie, Valentina Shevchenko, and Cris Cyborg, making her the most dominant woman in UFC history.

Dana White praised Nunes prior to Saturday's fight, saying that she's been "dropping guys in camp."

“She’s one of my all-time favorites,” White said of Nunes. “She doesn’t care who she’s fighting, she’ll fight anybody. One of the sweetest people that you’ll ever meet, very, very easy to deal with, but once she steps inside the octagon, she’s an absolute savage.

“What’s scary about her right now is Dan Lambert, the guy that runs her team, is saying he doesn’t understand why but she looks better than she’s ever looked in this camp, and she was dropping guys in camp. So this is gonna be interesting.”
