Ronda Rousey already has her hands full with Gina Carano ahead of the pair's dual returns to MMA atop Netflix's May 16 mega-event. But at Wednesday's pre-fight press conference in New York, Rousey also sent verbal heat-seeking missiles toward the sitting UFC bantamweight champion, Kayla Harrison.

In a recent interview on Jorge Masvidal's "Death Row MMA" podcast, Harrison reacted to a story Rousey told from their judo pasts about one of their "king of the hill" style training sessions. The sessions consisted of testing a single judoka for as long as they could, with the rest of the gym going at them for a set period. In Rousey's story, she claimed to take out all the women until a male judoka took her out after an hour of the session. Harrison labeled the story a "blatant f***ing lie," before mocking the concept of Rousey vs. Carano and calling each woman irrelevant, given the hiatuses they've been on.

Rousey, 39, erupted with an unexpectedly scathing response Wednesday.

"Gina is so relevant that she's the whole reason that the 145-pound division even exists," Rousey told Uncrowned's Ariel Helwani. "I am so relevant that the only reason [Harrison] has a job at the UFC is because of me. Kayla is so irrelevant that she couldn't even keep the 145-pound division around. Honestly, she's just sour because no matter what she does or what she accomplishes, she can't change the fact that she has the charisma of a wet towel and will always be in me and Gina's shadow. 

"So the next time she wants to talk s***, she should look down at her feet and consider who paved the road that she's walking on. Oh wait, she can't look down at her feet because she's too busy holding onto the belt in a neck brace. And then she goes on and says that I lied about training in judo in Canada in, like, 2006. Who the f*** are you to call me a liar, OK? I was training there for five months. B****, you weren't even there.

"Over the last decade and a half of being a public figure, I have cultivated a reputation of being unabashedly truthful. This b**** just got here and was already caught in a lie. What did she say after she won the belt? She said, 'Oh, I'm never going to say anything bad about Ronda. She took care of me when I was broke in Japan and bought me groceries.' How about you shut the f*** up and eat your groceries?"

The inaugural UFC bantamweight champion didn't stop there.

Comparing their two situations, Rousey took her rebuttal one step further, digging into Harrison's last scheduled bout — a showdown with Rousey's former opponent, Amanda Nunes. The fight was set for UFC 324 this past January until Harrison withdrew due to a neck injury that required surgery. 

Before its cancellation, the bout positioned a seemingly unstoppable champion against the returning women's GOAT, who retired on top. Yet Harrison vs. Nunes was also set to play second fiddle as UFC 324's co-main event behind an interim lightweight title clash between Justin Gaethje and Paddy Pimblett.

"Her and [UFC CBO] Hunter [Campbell] are trying to act like her next upcoming fight is the biggest women's fight of all time," Rousey said. "Then why is it being booked as a co-main for a men's interim title fight? The b**** isn't even bigger than Paddy 'The Baddy' [Pimblett]. No offense to Paddy, I think he's got more potential than anybody in the UFC, and he should call me when his contract runs out.

"Here's another contradiction that I think is a f***ing kicker: If she thinks that her fight is the biggest women's fight of all time, why is she getting paid less now than I was 10 years ago? Riddle me this, b**** — are you overvalued or are you underpaid? And what really pisses me off more than anything else — yeah, I'm not f***ing done — is how small she thinks. [My fight] is not just the biggest women's fight of all time — this is the biggest MMA fight of all time. It's going to get the most views, on the biggest platform, on the card with the biggest stars, and will be headlined by two women who dare to dream big. And this dream is going to bring more opportunities and greater revenue share to fighters than they've ever had before, because this fight is bigger than just me and Gina. It's bigger than anybody on this stage. It represents an unstoppable force of change in this industry, spearheaded by the fighters themselves.

"Bet your f***ing ass this is the biggest MMA fight of all time. Bar none."

Since Rousey vs. Carano was announced, Rousey (12-2) has explicitly done her best to become a new voice of reason and change throughout the MMA space. That shift has come as a massive surprise, given that she left the sport in 2017 to pursue a professional wrestling career. While Rousey has had equally distasteful things to say about both industries over the past decade, she knows how impactful the first MMA event on Netflix can be.

For starters, every fighter on the Netflix card will make a minimum of $40,000, according to Rousey. That significantly outpaces UFC's base pay of $12,000 to show and $12,000 to win.

"Fighting for MVP and on Netflix, it makes this fight bigger than us. It's a game-changer for the entire industry," Rousey said. "Everything's going to be different for all of the fighters after this. This is an experiment that Netflix is undertaking. We're going to outperform every single expectation on this card. UFC is going to have somebody to bid against in the future, and the fighters are actually going to have some bargaining power, and this is part of us taking our power back."

"I saw that Mike Tyson had something still [when he fought Jake Paul] that everybody misses, even at [age] 60," Rousey continued. "They put on the most-viewed combat sports event of all time. And I knew that me and Gina bring something to the table that people miss and it would be a huge success. It wouldn't be nostalgia bait or a cash grab.

"A vacuum has been left, and I think we need to remind all of the women and everybody in the sport to not just be comfortable with their place. You need to demand your space and demand your opportunities and try to aim for more. Everyone's content with what they have."
