The Cobra Kai cast comes from broad backgrounds. On the one hand, one of the main actors is Ralph Macchio, who plays an adult version of the classic Karate Kid character Daniel LaRusso. William Zabka also reprises his role as Johnny Lawrence, bringing back another character from earlier on in the Karate Kid franchise. Including these familiar faces makes Cobra Kai seem more connected to the original franchise, and draws in a potentially wider audience of those familiar with the older characters.
