From bullied child to ONE Championship's first three-sport world champion, the Thai fighter's story is one of resilience, ambition, and breaking barriers

RRAYONG, Thailand — Long before she became the first fighter in ONE Championship history to claim world titles in three different combat sports, Nadthawan Panthong was just another small girl from the rice fields of eastern Thailand, trying to survive the schoolyard.

Born on November 16, 1997, in the coastal province of Rayong, young Nadthawan faced a problem familiar to countless children: bullies. Unlike most, however, her solution would set her on a path that would eventually make history. At just five years old, she turned to Muay Thai for self-defense, learning the ancient art of eight limbs from her father, Wisanlek Lukbangplasoy, himself a former fighter.

"I was just an ordinary girl, helping my parents on the fruit farms," Stamp recalls of her early life among Rayong's rubber, durian, and rambutan orchards. But there was nothing ordinary about what would happen next.

One year after taking her first lesson, the six-year-old stepped into the ring for her professional debut. The fight lasted less than 30 seconds. A knee strike. A knockout. A champion was born.

"The bell rang, I attacked my opponent by knee, and I just won," she says of that hazy, adrenaline-fueled moment that would define her future.

But being a female fighter in rural Thailand came with its own battles. "When I was young, I was the only female fighter in my village's Muay Thai gym," Stamp remembers. "Back then, people weren't open to girls competing. They were afraid we might get hurt badly because they thought women were physically weaker than men, but my parents supported my dreams and encouraged me."

That parental support proved crucial. While other young girls her age focused on schoolwork and farm chores, Stamp was rising at 5 a.m. for morning runs before heading to class. "I was always too late to participate in the morning activity," she admits with a laugh.

Her extraordinary talent caught the eye of American documentary filmmaker Todd Kellstein, who was researching child boxing in Thailand. The resulting 2012 film, "Buffalo Girls," chronicled the lives of eight-year-old Muay Thai fighters Stam (as she was then known) and Pet Chor Chanachai as they competed throughout rural Thailand to support their families.

The documentary, which premiered at the 2012 Slamdance Film Festival, offered an unflinching look at the economic realities that drive Thailand's child boxing circuit. For families in impoverished farming communities, a child's fight purse could equal a month's rent or exceed what a farmer earned in weeks of labor.

"When I first saw the children boxing, I absolutely thought it was horrible," director Kellstein admitted. But after two years documenting this world, his perspective evolved. "It is difficult to understand the economic circumstances that lead to child boxing, but what now angers me is economic inequalities in the world."

Young Stam emerged from the film radiating confidence and determination—qualities that would carry her far beyond those rural arenas. By her teenage years, she had become a local stadium champion and claimed titles in two divisions across Eastern Thailand.

At 18, Stamp made a decision that would transform her from regional star to global phenomenon: she moved to Pattaya to train at the legendary Fairtex Gym. The world-renowned facility would become more than just her training ground—it would give her the name she'd carry to international fame: Stamp Fairtex.

But the move represented more than a change of address. At Fairtex, she began studying Brazilian Jiu-Jitsu under coach Jason Burnworth, laying the groundwork for what would become an unprecedented multi-sport career. Her dedication to the grappling art was immediate and impressive—by 2019, she had won gold at the Siam Cup BJJ tournament in the women's gi 58.5 kg division.

"She was my first student at Fairtex over five years ago," Burnworth would later say when promoting her to purple belt in 2022. "No one works harder and has a better smile."

When Stamp stepped into the ONE Championship circle on October 6, 2018, few could have predicted what was about to unfold. In her promotional debut, she didn't just win—she defeated Kai Ting "Killer Bee" Chuang by unanimous decision to claim the ONE Atomweight Kickboxing World Championship.

Four months later, she made history. At ONE Championship: Call to Greatness on February 22, 2019, Stamp defeated Janet Todd by unanimous decision to capture the inaugural ONE Atomweight Muay Thai World Championship, becoming the promotion's first-ever two-sport world champion.

But Stamp wasn't finished writing her story.

While dominating in striking sports, she had been quietly building her mixed martial arts credentials. After Rich Franklin scouted her for MMA, she made her debut on ONE Warrior Series in July 2018, knocking out Rashi Shinde with a head kick in just 19 seconds. She received her blue belt in Brazilian Jiu-Jitsu following a rear-naked choke submission victory over Asha Roka in her ONE Championship MMA debut.

The skeptics doubted whether a pure striker could compete with wrestlers and grapplers. Stamp silenced them by winning the 2021 ONE Women's Atomweight World Grand Prix, submitting elite wrestler Ritu Phogat in the tournament finals. Though she fell short against the legendary Angela Lee in their 2022 title bout, the fight proved Stamp belonged among MMA's elite.

September 29, 2023, at Singapore Indoor Stadium. That's when Stamp Fairtex etched her name permanently into combat sports history.

In the main event of ONE Fight Night 14, she faced South Korea's Ham Seo Hee for what was initially scheduled as an interim title bout. But moments before their walkout, reigning champion Angela Lee made an emotional announcement, retiring from competition to focus on mental health advocacy following her sister Victoria's tragic death. The fight became for the undisputed championship.

Stamp rose to the moment. After a competitive first two rounds, she unleashed a brutal third-round assault, finishing Ham with a barrage of strikes at 1:04 of the frame to claim the ONE Women's Atomweight MMA World Championship.

"It feels amazing," an emotional Stamp told the crowd through her limited English. "I have made my own history today, and it feels incredible."

She had done what no fighter—male or female—had ever accomplished in ONE Championship: captured world titles in Muay Thai, kickboxing, and mixed martial arts.

In a touching moment, Lee embraced her successor in the center of the cage, passing the torch to the woman who had idolized her. "I just want to say I love you so much, and you're my idol always," Stamp told Lee. "I'm very sad that she doesn't want to continue her journey in MMA or in ONE Championship. I want to let her know that she has always been my idol since the first day I started MMA, and she will always be my idol."

But triumph gave way to tribulation. A torn meniscus suffered during training would sideline Stamp for nearly two years, forcing her to withdraw from multiple scheduled title defenses. The injury required surgery and extensive rehabilitation. In May 2025, facing continued setbacks in her recovery, she made the difficult decision to relinquish the MMA championship she had worked so hard to win.

"Thank you, Khun Chatri, for believing in me even when I didn't believe in myself," she had said after winning the title, referring to ONE Championship CEO Chatri Sityodtong. Now, she would need that belief more than ever.

On November 16, 2025—her 28th birthday—Stamp Fairtex made her return to competition at ONE 173 in Tokyo's Ariake Arena. Facing former K-1 flyweight champion Kana "Krusher Queen" Morimoto in an atomweight kickboxing bout, Stamp was stepping back into competition under the sport where her journey had begun, rather than immediately returning to the all-encompassing demands of MMA.

"I decided to go for kickboxing before MMA because I wanted to warm up my body first," she explained. "I've been away for two years, and the muscle I lost after the surgery is all gone."

The fight proved to be a stern test. Morimoto, aggressive from the opening bell, targeted Stamp's surgically repaired leg and used superior speed to control the cage. Though Stamp showed her trademark heart and willingness to trade strikes, the Japanese veteran's pressure proved too much. After three rounds, Morimoto earned a unanimous decision victory, spoiling Stamp's comeback on her birthday.

For Morimoto, it was the opportunity of a lifetime realized—a chance to defeat a legend and establish herself as a contender. For Stamp, it was a humbling reminder of the challenge ahead.

"The reason I accepted the fight with Kana is that I feel she is the best in kickboxing in Tokyo, in Japan," Stamp had said before the bout. "I feel it's a challenge. Whether I win or lose, there's no harm in fighting her."

At 28, Stamp Fairtex stands at a crossroads. The loss to Morimoto stings, but her resume speaks for itself: she remains the only fighter in history to claim world championships across three combat sports in a major global promotion. Her journey from a bullied child in rural Thailand to international martial arts icon has already secured her place in the sport's history books.

But Stamp has never been one to rest on her accomplishments. Having tasted defeat in her comeback, the question now is how she responds. Will she continue to rebuild in kickboxing? Will she eventually return to reclaim MMA glory? Or might she even pursue that strawweight championship she was once scheduled to challenge for?

"I just want to focus," she has said about her fighting career, a simple statement that has defined her entire journey.

From those early morning runs before school in Rayong, through the brutal child boxing circuit captured in "Buffalo Girls," from the Fairtex Gym training rooms to the bright lights of ONE Championship's biggest stages, Stamp Fairtex has remained focused. On improvement. On history. On proving wrong anyone who doubted what a girl from the rice fields could accomplish.

Her story is far from over. The three-sport queen may have stumbled on her birthday, but champions aren't defined by a single fight. They're defined by how they respond to adversity—something the girl who started fighting at five to defend herself against bullies knows something about.

As she evaluates her next move, one thing remains certain: whatever Stamp Fairtex decides to do next, the world will be watching. Because if history has taught us anything, it's never wise to count out a fighter who has already made the impossible look routine.

The same event that saw Stamp's comeback attempt also witnessed another milestone in Muay Thai history: Nadaka Yoshinari captured the vacant ONE Atomweight Muay Thai Championship, claiming the title that Stamp once held. The torch continues to be passed in Thailand's proud striking tradition, with new champions rising even as legends rebuild.

But for Stamp Fairtex, the journey continues. From the rice fields of Rayong to the global stage, her story remains one of resilience, determination, and the unshakeable belief that barriers exist to be broken.

The question isn't whether she'll fight again. It's what history she'll make when she does.
