@ThanhHauTranDo and if you know if it's okay of course I thought of another fanfic idea, how about gaolang wongsawat from the kengan universe in avatar the legend of korra? Like he would be a real character who was born and lives in this world he is a non-bender who is the last user of the forgotten martial art muay thai because his place of origin was destroyed in the 100 year war and only his grandfather was able to pass it on to his grandson, he ended up being killed by the red lotus because he was a threat to his plans, after a while he was adopted by Korra's parents before she was born which made him become Korra's older adoptive brother in this fanfic, and that he himself seeing the weaknesses of muay thai created a fighting style of punches and dodges which gave the name boxing and muay thai together with boxing and his well-worked body he became one of the most powerful non-benders, where he would spend the adventures with his sister korra, what do you think?
