The war of words between Kayla Harrison and Ronda Rousey has intensified, with the reigning UFC women's bantamweight champion pushing back hard against the Hall of Famer's claims ahead of her long-awaited MMA return.

Rousey Labels Comeback Fight "Biggest in Women's History"

Rousey is set to make her first MMA appearance since 2016 against Gina Carano in the main event of the MVP MMA 1 card, promoted by Most Valuable Promotions on Netflix next month. In promoting her comeback, Rousey has labeled the Netflix headliner as the biggest women's fight in history, even suggesting that her payday will dwarf what today's UFC champions earn, claiming Harrison makes less than a tenth of what she did during her peak.

Harrison Responds: "I Could Be Meaner"

Harrison, however, isn't buying into the narrative. Speaking during the recent UFC Vegas 116 pre-fight show, she pushed back on Rousey's claims.

"I'm just going to go ahead and say I could be meaner," Harrison said. "I think that it would be really hard. I can't imagine what it would be like for someone to come in and beat everything I've ever done. That would be hard. I get it."

Harrison believes Rousey's anger stems from jealousy that somebody has taken her spot as the top women's fighter in the UFC.

"Imagine hating me and I'm just over here in my backyard feeding chickens. It's got to be rough."

Harrison Acknowledges Rousey's Legacy but Dismisses Fight's Stature

Despite the criticism, Harrison acknowledged Rousey's foundational role in women's MMA.

"I will never take away the fact that Ronda is probably the most important female fighter," Harrison said. "If it weren't for her, for sure, I wouldn't be where I'm at. I wouldn't have a job. But this fight is not the greatest fight of all time."

She added, "I think that the part that bothers me most about Ronda is at one point she was a real athlete. She was training for the Olympics. She's an Olympic bronze medalist. She became a UFC champion. She was really trying to chase greatness."

Harrison Points to Realities of Rousey vs. Carano

Harrison doubled down on her stance, pointing to what she sees as clear context behind the hype surrounding Rousey's comeback. Rousey is returning after nearly a decade away from MMA, having suffered back-to-back knockout losses in her final Octagon appearances: against Holly Holm at UFC 193 and Amanda Nunes at UFC 207. Her opponent, Gina Carano, has been out of competition even longer. The former pioneer last fought in 2009, making this a return after a 17-year absence from combat sports.

"It's between someone who hasn't fought in 10 years and is coming off two knockout losses and another woman, again another legend, another pioneer, but hasn't fought in 17 years and is in her 40s," Harrison said. "Don't call it the greatest fight of all time. I'm chasing greatness. You're chasing money. We're different."

Harrison's Own Path: Nunes Fight Looms

Harrison currently reigns as the UFC women's bantamweight champion and is expected to face Amanda Nunes later this year after their initial clash at UFC 324 was scrapped due to Harrison's neck injury and subsequent surgery. Her anticipated showdown with Nunes carries far more legacy-defining stakes, with the potential to determine the greatest female fighter in MMA history.

By all indications, Harrison's recovery is progressing well, and the reigning champion is expected to make her return to the Octagon before the end of 2026.

While Rousey is preparing to face Carano in May, Harrison made it clear that popularity doesn't necessarily equate to greatness.
