"Using the crane kick trained and perfected by Mr. Miyagi (Pat Morita), Daniel (Ralph Macchio) knocks out Johnny (William Zabka) and wins the tournament! Movie over, everyone cheers! Except — was this move legal? Should Daniel have been disqualified? Was he the secret villain of The Karate Kid the entire time? Earlier in the film, it’s said that “hits to the face” are not permitted, not specifying whether that includes kicks. Macchio himself called the crane kick a clear violation, and the later YouTube series Cobra Kai features its alleged legitimacy as a prominent plot point."
