It's unclear if the skilled and vicious karate fighter will remain loyal to his Cobra Kai roots or if he'll unexpectedly join sides with the Eagle Fang/Miyagi-Do Karate dojo.

Barnes was mentioned in the Cobra Kai episode 'All Valley' due to his unsportsmanlike behavior previously getting the dojo banned from participating in the All-Valley Karate Tournament.
