Ralph Macchio as Daniel LaRusso
Ralph Macchio returns as Daniel LaRusso, the protagonist he first played in The Karate Kid. In Cobra Kai, Daniel is an established businessman and father who remains committed to the lessons of Mr. Miyagi.
His conflict with Johnny is no longer simply about winning karate matches. Daniel’s approach to teaching, family, rivalry, and Miyagi-Do’s traditions becomes one of the show’s major story threads. Macchio also serves as an executive producer. netflix Media Center
William Zabka as Johnny Lawrence
William Zabka reprises Johnny Lawrence, Daniel’s former rival from the 1984 tournament. The character begins the series in a very different place from his younger years, eventually reopening Cobra Kai and mentoring Miguel.
Johnny’s relationship with Robby, his complicated history with Daniel, and his attempts to build a new life give the character considerably more depth than his original role suggested. Zabka also serves as an executive producer on the series. Netflix Media Center
Xolo Maridueña as Miguel Diaz
Xolo Maridueña plays Miguel Diaz, one of the show’s most important young characters. Miguel becomes Johnny’s first major student and represents the beginning of Johnny’s transformation as a mentor.
His friendships and rivalries with Robby, Hawk, Demetri, and other students help drive the younger generation’s storyline. Maridueña is also one of the three stars specifically highlighted by Netflix on the show’s official page. Netflix
Mary Mouser as Samantha LaRusso
Mary Mouser portrays Samantha LaRusso, Daniel and Amanda’s daughter. Sam grows from a teenager caught between competing influences into a confident martial artist who develops her own understanding of Miyagi-Do.
Her rivalry with Tory and her relationships with Miguel and Robby place her at the center of several major conflicts. Netflix’s behind-the-scenes coverage also identifies Mouser as part of the young ensemble that grew with the series. Netflix
Tanner Buchanan as Robby Keene
Tanner Buchanan plays Robby Keene, Johnny’s estranged son. Robby’s journey is closely connected to both Johnny and Daniel, making him one of the characters who most clearly bridges the two sides of the story.
His martial-arts development and changing relationships with his father, Daniel, Miguel, and Tory become increasingly important as the series progresses. Netflix
💡 Pro Tip: If you’re watching the series mainly for character development, pay attention to the changing relationships between Daniel, Johnny, Miguel, and Robby. Their connections explain much of the show’s emotional progression beyond the tournament fights.
More Important Cobra Kai Actors
The cast of Cobra Kai extends well beyond its six most recognizable young and veteran stars.
Jacob Bertrand plays Eli “Hawk” Moskowitz, whose transformation is one of the show’s most visible character arcs. Gianni DeCenzo portrays Demetri, while Peyton List plays Tory Nichols, a fighter whose difficult circumstances influence many of the series’ conflicts. Netflix
Martin Kove returns as John Kreese, Johnny’s former sensei and one of the franchise’s defining antagonistic figures. Thomas Ian Griffith also returns as Terry Silver, another major figure from The Karate Kid universe. Yuji Okumoto reprises Chozen, connecting the series to another character from the original films. Netflix Media Center
Courtney Henggeler plays Amanda LaRusso, while Vanessa Rubio portrays Carmen Diaz. Their characters provide an important perspective on the consequences of the dojo rivalries away from karate.
The later seasons also introduce and expand younger performers, including Dallas Dupree Young as Kenny, Griffin Santopietro as Anthony LaRusso, Oona O’Brien as Devon, and Alicia Hannah-Kim as Sensei Kim Da-Eun. Netflix’s Season 6 information also lists Rayna Vallandingham as Zara, Patrick Luwis as Axel, and Lewis Tan as Sensei Wolf. Netflix Media Center
How the Cast Connects to The Karate Kid
One reason the cast of Cobra Kai feels distinctive is the way it combines legacy characters with a new generation. The series premiered in 2018 and revisited Daniel and Johnny more than three decades after their original confrontation. Netflix
Rather than simply recreating the 1980s movies, the show uses the older characters to introduce new students and conflicts. Miguel, Sam, Robby, Tory, Hawk, and Demetri gradually develop their own identities, while characters such as Chozen, Kreese, and Silver reconnect the television series with the wider Karate Kid mythology.
Netflix describes the sixth season as the conclusion of the series, with the final storyline bringing Miyagi-Do and Cobra Kai into the international Sekai Taikai competition. Netflix Media Center
📌 Key Takeaway: The cast of Cobra Kai works because the series does not rely only on nostalgia. Ralph Macchio and William Zabka anchor the original rivalry, while the younger actors carry a new generation of relationships, rivalries, and karate stories.
