The story

Stamp Fairtex, born Nadthawan Panthong in Rayong, has competed in Muay Thai since early childhood and won the Thepprasit Stadium light flyweight title in Pattaya before becoming a global name. In ONE Championship she won the atomweight kickboxing title in 2018 and the atomweight Muay Thai title in 2019, then crossed over to MMA, won the 2021 atomweight Grand Prix with an armbar and took the MMA world title in 2023 by stopping Ham Seo-hee with body punches. That made her ONE's first three-sport world champion. A knee injury forced her to give up the MMA belt in 2025, but she returned to Muay Thai with a win in 2026 and was ranked third in ONE's atomweight Muay Thai division that September.
