Kwon is a character introduced in Cobra Kai as a member of the Cobra Kai dojo. He is portrayed as a skilled martial artist who becomes involved in key confrontations throughout the series.
Unfortunately, Kwon meets his tragic death in Episode 9 (The Last Dance) of Season 6 and will not appear in Season 6 Part 3. He is stabbed during a violent altercation at the dojo, which escalates tensions and brings emotional consequences for Johnny Lawrence and the other characters.
His death becomes a catalyst, shifting the dynamics of the story and contributing to the emotional tone of the series' conclusion. Since Season 6 wraps up many storylines, Kwon's return in future content is unlikely, except perhaps through flashbacks.
