When I first watched the first season of Cobra Kai, I thought that the final scene was a bit visually similar to the Joker reveal scene from the 1989 Batman film. The Cobra Kai scene is shown in its entirety, unaltered, while the Batman scene, which is quite longer, is cut at 0:29 , 0:37 , 0:40 , 0:49 and 0:54.
