Susan is a minor character and Ali's best friend in The Karate Kid, who is first seen, at the beach, with Ali. She doesn't speak during this scene, but she could have been one of the girls with Ali. Susan has her first speaking line, when asking Daniel what kind of bike he rode. She isn't seen again, until she confronts Daniel for spying on Ali at the country club. She also happens to have her most famous catch phrase in this scene, "You didn't stick around for the exciting conclusion!" That also happens to be her last scene, and she is not mentioned at all in Cobra Kai, nor in a flashback. She is played by Juli Fields. She also happened to go to High School with William Zabka, who played Johnny Lawrence.
