Growing up in Buriram, Thailand, Sitthichai “Killer Kid” Sitsongpeenong was immersed in the world of martial arts. At just 9 years old, Sitthichai’s father began teaching him Muay Thai for self-defense, but he took those talents to the ring, using his prize money to fund his education.
By the time he was 15 years old, Sitthichai had already built a reputation for himself as a fierce competitor at Bangkok’s iconic Lumpinee Boxing Stadium. In fact, in 2014 he won the prestigious Lumpinee Stadium Welterweight Muay Thai World Title.
“Killer Kid’s” impressive skill set and larger build soon caught the attention of international promoters, and he found himself successfully competing outside of his home country. Eventually, Sitthichai went on to become a multiple-time Glory Lightweight Kickboxing World Champion.
Nowadays, Sitthichai is known for his aggressive fighting style and spectacular knockouts, which have accounted for nearly a third of his victories. Arguably one of the most famous southpaw fighters in the world, he joined ONE in 2020 and has defeated the likes of Tawanchai PK Saenchai and Tayfun Ozcan.
With an impressive professional record and eight World Titles in the striking arts, “Killer Kid” has earned his place in history as one of the greatest of all time. However, the Thai superstar is now committed to obtaining the final missing jewels on his crown — the ONE Featherweight Kickboxing and Muay Thai World Championships.
