He quickly finds himself the target of bullying by a group of high school students, led by Ali's ex-boyfriend Johnny, who study karate at the Cobra Kai dojo under ruthless sensei, John Kreese. Fortunately, Daniel befriends Mr. Miyagi, an unassuming repairman who just happens to be a martial arts master himself.
