Netflix have announced that Dallas Dupree Young and Oona O’Brien have signed up for recurring roles, while Vanessa Rubio and Peyton List promoted to series regulars for the upcoming fourth season of Cobra Kai.

The series is a sequel to that of The Karate Kid original, set thirty years after the evens of the 1984 All Valley Karate Tournament, where we find a down and out Johnny Lawrence who, seeking redemption, reopens the infamous Cobra Kai dojo. It reignites his rivalry with a new-successful Daniel LaRusso, who has been struggling to maintain balance in his life without the guidance of his mentor Mr. Miyagi.

Dallas Dupree Young (whose credits include The Big Show Show and The Main Event) will be playing the role of Kenny, a bullied new kid in school who turns to karate as a way to defend himself. Newcomer Oona O’Brien will be playing the role of Devon, a potential new karate student who is relentlessly competitive, a quick study, and equally quick-tempered when she’s provoked. Vanessa Rubio has been recurring since the first season as Miguel’s hard-working mother Carmen, while Peyton List has been recurring since the second season as troubled teen/Cobra Kai student Tory Nichols.

The series has become a big hit since its move to Netflix from YouTube Red, becoming number one worldwide on the streamer when the third season debuted back in January. The fourth season is currently in production in Atlanta.

The new additions will join a cast that also includes William Zabka, Ralph Macchio, Martin Kove, Courtney Henggeler, Xolo Maridueña, Tanner Buchanan, Mary Mouser, Jacob Bertrand and Gianni Decenzo for the fourth season.
