PBA Thailand Champion Supergirl Jaroonsak Muaythai began training with her father, a former professional Muay Thai boxer, at home when she was just 3 years old. He encouraged both Supergirl and her sister, fellow ONE Championship athlete Wondergirl, to train in Muay Thai, contrary to the rigid traditions that have governed the sport for centuries, believing that the martial art had much to offer them.
With the support of her family, Supergirl participated in over 40 Muay Thai bouts by the time she was 16 years old, and she continues to grow and improve as a professional athlete while still attending high school. She is well-known around the world for a unique spearing knee technique that she throws often with great success and for having the poise of a seasoned veteran despite her youth.
Supergirl followed her older sister into ONE Super Series and became the youngest athlete on the roster. Representing the family gym in southern Bangkok, she is an exciting new addition to the ONE Super Series atomweight division and is looking to make an immediate impact.
