Who Plays Johnny Lawrence in Cobra Kai — and Why William Zabka Was Born for This Role

William Zabka plays Johnny Lawrence in Cobra Kai, and if you’re having trouble remembering the name, it’s actually one of the things that makes the entire narrative worthwhile. Born in New York City on October 20, 1965, Zabka spent his childhood on Long Island before relocating to the San Fernando Valley in California with his family. When he got the part of Johnny Lawrence in The Karate Kid, he was halfway through his first semester as a film major at Cal State Northridge. He left school. The movie’s last scene was filmed in the campus gym. That detail is almost too neat, but it still happened.

It’s important to keep in mind that Zabka didn’t have any karate training when he was cast in 1984. He was a wrestler. His portrayal of the antagonist, a blond, menacing Cobra Kai dojo student who spends the majority of the movie making Daniel LaRusso’s life difficult, was so successful that it followed him for years. In interviews, he said that he was occasionally harassed in public by strangers. There are costs associated with being such a convincing villain.

Although not without incident, the decades between The Karate Kid and Cobra Kai were more subdued than his heyday in the 1980s. Most, a short film he wrote and produced and which was shot in Poland and the Czech Republic, debuted at Sundance and won prizes at multiple film festivals. He was nominated for an Academy Award in 2004 for Best Live Action Short Film. The name of a man who is most known for sweeping someone’s leg doesn’t typically receive that kind of recognition. It provides insight into Zabka’s true activities over the years when the spotlight had shifted.

When Cobra Kai was first announced for YouTube Red and then Netflix in 2017, there was probably some legitimate doubt about whether a Karate Kid revival could succeed at all, much less one that featured the original antagonist at its core. Skepticism might have undervalued Zabka as well as the writing. Over the course of the six seasons of the show, which ended in 2025, Johnny Lawrence developed into something genuinely complex: a man carrying decades’ worth of poor decisions, gradually learning how to do better, and often failing before he got there. Zabka directed an episode and co-executive produced the show with Ralph Macchio.

The reaction from fans was remarkable, especially in the later seasons. Watching the later episodes gives the impression that viewers weren’t just cheering for a character; rather, they were cheering for Zabka to receive the credit the role merited. He was nominated for both the Critics Choice Award and the Emmy. He sang Johnny’s theme song live in front of a sold-out audience at the Whiskey a Go Go in 2019. In addition, he has played the guitar since he was a young child and attended the Dick Grove School of Music. The show eventually figured out how to make use of the man’s multitudes.

In 2025, he made a brief appearance as Johnny Lawrence in Karate Kid: Legends, indicating that the character isn’t completely retired. He was reportedly given a recurring role in the second season of the Amazon Prime Video series Scarpetta in May 2026. Zabka, 61, continues to regularly practice Tang Soo Do, a discipline he learned while filming the first Karate Kid and eventually earned his second green belt. When he’s not on set, he goes scuba diving and surfing. It’s difficult to ignore the fact that the man who played the archetypal bully in the 1980s has evolved over the years into someone far more fascinating than that moniker ever implied.
