Prajanchai PongSuphan PK

Before bringing his talent to the world’s largest martial arts organization, Prajanchai PongSuphan PK had already left an indelible mark on Muay Thai.​
​
The Bangkok native competed in over 400 professional bouts, squared off against the best fighters on the planet, and gained a massive following that admired his remarkable agility, devastating strikes, and impeccable defensive skills.

Prajanchai’s electrifying performances have earned him numerous victories and accolades across multiple divisions. Notably, he has etched his name in Muay Thai history by capturing both the prestigious Lumpinee Stadium and Rajadamnern Stadium World Titles in two different weight classes.​
​
Regarded as one of the greatest pound-for-pound fighters, Prajanchai directed his career path to ONE Championship in 2021, receiving an opportunity to add more glimmer to his legacy.​
​
In his highly anticipated debut, he dethroned his legendary compatriot Sam-A Gaiyanghadao by majority decision to capture the ONE Strawweight Muay Thai World Championship.​
​
His reign was cut short in May 2022, but Prajanchai earned his way back to the gold. First, he beat Sam-A in a rematch to claim the interim belt in June 2023, and then he beat his Italian rival, Joseph Lasiri, to unify the ONE Strawweight Muay Thai World Title in December 2023. Prajanchai also defeated Jonathan Di Bella in June 2024 to become the ONE Strawweight Kickboxing World Champion and cement himself as one of the greatest pound-for-pound strikers on Planet Earth.​
​
Although Di Bella defeated him in a grueling five-round war to take back the kickboxing belt in October 2025, Prajanchai is motivated to earn a World Title trilogy and achieve two-sport supremacy once again.
