Ronda Rousey proved that she can still look intimidating even in a low-cut, sexy black dress. The UFC fighter made an appearance on NBC's "The Tonight Show Starring Jimmy Fallon" to promote her upcoming fight against the 19-time boxing world champion Holly Holm, TIME reported. During her visit, she showed off her game face and challenged host Jimmy Fallon to a "Mario Kart 8" rematch.

Fallon showed Rousey a photo of her opponent, Holm, whom she'll face off against on Nov. 14 at UFC 193, according to Rolling Stone. Rousey started to discuss one of the possible outcomes of the match with Fallon.

"She's undefeated and an amazing athlete and the biggest threat definitely to me," Rousey told Fallon. "I feel like she's gonna try to keep distance and keep far away from me and get me frustrated to a point where I'll make a mistake..."

Fallon noted that Rousey's facial expression changed drastically when she started to discuss her upcoming match and asked her to show him her game face.

"Well when I was a little kid, my godfather was trying to give me like tips on how to have a game face and he was like 'You have to look at them through your eyebrows,'" she said. "So he was like 'You put your head down and you look up through your eyebrows at them and you look as mean as you can' and I'm like 11 years old like 'Okay I'm gonna look mean!'"

She explained that now she just thinks about the moves she's planning to use on her opponents during their fight, and she lets her face express those thoughts. Fallon asked if Rousey thinks of nice thoughts when she looks at him, and she said yes.

"Except for when it comes to 'Mario Kart,'" she added.
