I guess if we take any fighter and search for his story, then his life story would be worthy of a Netflix adaptation. People rarely go train any combat sport because of happy life. People rarely become a professional fighter only because they are good at beating other guys. Imho there is never a guy, whos parents were billionaires, and due to boredom, he began training martial art, all of a sudden he realises that he has a talent and becomes a champion. This is plot of a movie from 80s-90s only.
