10. Tony Jaa
Tony Jaa brought Muay Thai to the global stage with Ong-Bak, performing jaw-dropping stunts without wires or CGI. He has been trained in Muay Boran (an older, more brutal form of Muay Thai) since childhood and has added taekwondo, judo, and aikido to his skill set. Jaa’s real-life conditioning allows him to perform dangerous acrobatics while maintaining devastating striking power. Watching him fight is like seeing a martial arts master in action, because that’s exactly what it is.
