Parinya Charoenphol had a rocketing career as a Muay Thai kickboxer – 20 wins and 18 TKOs – where she made a name for herself as a gay teen boxer with heavy makeup. Her work was all towards one goal, though: saving up enough money for a sex change operation.
Since transitioning to a woman, Charoenphol has starred in a number of movies and even had her own biopic, Beautiful Boxer. Her mere presence has helped turn assumptions about the male-dominated sport of Muay Thai – and the conservative social underpinnings thereof – on their head.
