'Wondergirl' set for MMA debut at ONE 157, ready to follow in Stamp Fairtex's footsteps

The 23-year-old muay Thai star makes the switch to MMA on Friday, but predicts a submission finish.

Sisters Nat "Wondergirl" Jaroonsak and Anna "Supergirl" Jaroonsak are muay Thai stars who have found success in both their native Thailand and the ONE Championship circle.

But for some time now, "Wondergirl" – the older of the two – has sought to make the switch to MMA and achieve the same success as her idol, Stamp Fairtex.

At "ONE 157: Petchmorakot vs. Vienot" on Friday, she will officially kickstart her MMA career when she faces Indian strawweight Zeba Bano.

Jaroonsak knows she's got a lot of catching up to do to reach the heights of Stamp, her role model and the ONE women's atomweight world grand prix champion.

But if she does eventually find success in mixed martial arts, she cheekily admits to being curious about how she would fare in a contest with her superstar compatriot.

"For me, Stamp is my idol. She is smaller than me, but (could we) fight? Yeah, maybe," she said.

Just like the athlete she looks up to, Jaroonsak's career kicked off from a very young age. She and her little sister began learning the trade under the watchful eye of her father, former muay Thai fighter Jaroon Chanthasri, in Bangkok.

He passed on to them everything he knew about the traditional art, and that helped the siblings dominate the local scene.

"Wondergirl" competed locally to great success, eventually becoming a two-time Thailand muay Thai champion. She and her sister, "Supergirl," who claimed a PBA Thailand Title herself, would sign with ONE Championship in 2020 during the height of the COVID-19 pandemic.

"It's a good opportunity for me to fight for one of the biggest martial arts promotions in the world," the elder Jaroonsak sibling said.

The Thai quickly showcased her striking brilliance, as she knocked out Brooke Farrell in just 81 seconds in her promotional debut and then finished KC "Pinay Fight" Carlos via second-round TKO in her sophomore appearance.

Jaroonsak would fall to future ONE World Title challenger Jackie Buntan in February 2021, and while she wanted to earn some redemption, her desire to compete in MMA just kept growing stronger and stronger.

She had been learning Brazilian jiu-jitsu over the years, eventually becoming a blue belt in "the gentle art." Before that muay Thai fight with Buntan, she even competed in local Brazilian jiu-jitsu tournaments, where she picked up gold and silver medals.

And now, she is finally making the leap to MMA.

In anticipation of her MMA debut at ONE 157, she is preparing at Marrok Force, which is home to the likes of top-ranked ONE Championship fighters Denice Zamboanga and Fabricio Andrade.

"Wondergirl" will need to be at the top of her game, as Bano will serve as a tough test. The Indian is a perfect 6-0, and she has four first-round knockout victories and a submission win on her resume.

Despite Bano's reputation for knocking out her opponents, Jaroonsak isn't scared.

"I am a muay Thai professional fighter. And, of course, my striking (includes) everything in muay Thai – elbows, knees, clinch, head kicks, low kicks, even teeps," the 23-year-old Thai said. "If I'm her coach, I would find a way to take me down. But who knows? Maybe she's going to strike with me in all the rounds."

If the action hits the canvas, though, "Wondergirl" wouldn't be mad about it. In fact, she is calling her shot.

"I'll win this fight by rear-naked choke in the second or third round," she said.

Should that prediction come true, then it would mimic Stamp's first MMA fight in ONE Championship, where she submitted Indian striker Asha Roka via rear-naked choke in round three back in August 2019. From the sounds of it, "Wondergirl" could truly be walking in her idol's footsteps.
