Byeong Mun "Qudans" Son is a Korean Tekken player currently playing for UYU who is most known for his Devil Jin experience as well as winning the first ever Tekken World Tour Finals in 2017, defeating compatriot Saint in the Grand Final.


Qudans first began playing Tekken from the first game in the series at a young age casually. It was not until Tekken Tag Tournament that he began to play seriously [1], quickly making a name for himself in the South Korean Tekken scene and became an EVO Champion for the game in 2005, defeating Ryan Hart in the finals [2]. Qudans kept playing until 2007, retiring due to hand fatigue experienced from excessive exercising which even forced him to temporarily switch to using a Joypad for Electric Cancel 6 [3] (he won the Tekken 5 and Tekken Tag Tournament events regardless). After this Qudans went on a five year hiatus from competitive Tekken, enlisting in the Army, going to University and getting a part-time job.

After his hiatus Qudans made his return to Tekken after being convinced by fellow player Ji3moon Ace to start playing Tekken Tag Tournament 2 and was motivated as well after watching Knee playing for numerous tournaments. His rise to stardom once again started with Tekken 7 however winning multiple tournaments such as the first season of AfreecaTV TEKKEN League and the SEA Major with the latter victory ensuring him a place at the first Tekken World Tour Finals where he emphatically won the event after a 10 year absence from North American tournaments. Shortly after this he was sponsored by ROX Dragons for the next TWT circuit but later signed with UYU in early 2018.
