In Cobra Kai’s last season, Mr. Miyagi appeared though with the help of CGI in season 6, episode 13.
During an interview with The Direct, Ralph Macchio, who played Daniel LaRusso in the final season, was on a quest to find out about his master’s past as he was asked, “Was there ever any worry, like pushback against, like, the CGI [for the Mr. Miyagi scene]?”
The actor admitted, but added, “I mean, listen, I have a little pushback on it. I don’t think, you know, we didn’t have the budget to—my main concern is, I mean, my main thing is I wanted Daniel to be fighting side-by-side with Mr. Miyagi.”
He continued, “As far as a dialog scene, for me, it was more about them together and more about the thing that releases it, is it’s all in Daniel’s mind. It’s not really happening. It’s in his mind.”
“So you have a little leeway in. So I think it’s all in the message, if not perfect,” Ralph concluded.
