Johnny Lawrence (William Zabka) Daniel's first enemy, the main antagonist of the first film. He is Ali's ex-boyfriend, and defending All Valley Karate Tournament Champion. He is also John Kreese's top student at the Cobra Kai dojo and gang leader of the Cobra Kai. Although he plays the role of an alpha-male bully, when Kreese told Bobby to put Daniel out of commission, Johnny looked at Kreese in disgust. He was also disgusted with Kreese to forced him attack the weak spot which was Daniel's injured leg after telling him to "sweep the leg. you got a problem with that?". At that time realises he was wrong to bully Daniel due to Kreese's corrupted ways of teaching them martial arts. At the end of the film during the final round of the tournament, being the last Cobra Kai member defeated eliminated by Daniel, Johnny shows respect to him and says "You're all right, LaRusso" and personally gives Daniel the trophy himself, thanking him for the good match. In the second film, Kreese gets angry at Johnny for getting second place, but Johnny stands up for himself against Kreese, stating that he still did his best whether he won or lost. However, Kreese attempts to beat Johnny up after breaking his second place trophy, making it clear to Johnny, Daniel, Miyagi, and the rest of the Cobra Kai students that Kreese is really a sore loser. Fortunately for Johnny, Miyagi comes to the rescue by defeating Kreese, and Johnny and the rest of the Cobra Kai students decided to leave Kreese's dojo for good. In the 2010 Remake this character is Chinese and is called Cheng.
