Actor Sean Kanan, who played Mike Barnes in The Karate Kid III, has confirmed he spoke to the producers of the show, but couldn’t say much more than that.
Daniel may need the help of Chozen once more, especially given the current rumor that one of the most threatening villains from the character’s past could be on his way to Cobra Kai.
Barnes was one of Daniel’s most fearsome opponents in the original franchise, so it wouldn’t hurt for the character to ring up Chozen and ask if he had any more scrolls lying around that taught some more techniques he could use against Barnes if need be.
