Cobra Kai is a family show. It’s rated TV-14 so the worst words they’ll say are damn and sh**. Apparently, some of the cast members work blue behind the scenes. Tanner Buchanan, who plays Robby on Cobra Kai, copped to dropping swear bombs between takes. 

Buchanan joined his co-stars on stage for Cobra Kai: Live and Badass on May 5. During a trivia game, moderator Kristian Harloff asked the cast who is most likely to curse when they mess up a take. Cobra Kai Season 5 premieres Sept. 9 on Netflix

Tanner Buchanan admits to swearing on the ‘Cobra Kai’ set 

Buchanan plays Robby Keene, Johnny Lawrence (William Zabka)’s estranged son. It’s been a rocky road for Robby. He trained with Daniel LaRusso (Ralph Macchio) to get back at his father. He broke Miguel (Xolo Maridueña)’s back in their high school fight. After going on the run he ended up in juvie. Then he went back to John Kreese at Cobra Kai, although season 5 promises a reconciliation with Johnny. 

When Harloff asked the question, several cast members pointed to Buchanan and said, “Tanner” in unison. Buchanan did not deny it.

“Me, I know that one right away,” Buchanan said.

‘Cobra Kai’ producers told Tanner Buchanan to cool it with the potty mouth

Neither Buchanan nor his Cobra Kai co-stars would give examples of Buchanan’s curse words of choice. Mouser revealed it got so bad that the bosses had to step in.

“Tanner got a talking to actually,” Mouser said.

When Harloff suggested Buchanan’s mom scolded him, Buchanan joked, “I learned it from my mom.”

Had it been Cobra Kai creators Jon Hurwitz, Hayden Schlossberg, and Josh Heald, Buchanan probably would have named them. He just alluded to some unnamed producers who stepped in regarding his behavior. 

“I got it from some of the producers that maybe I should just try to quiet down some of it, some of the bad words on set,” Buchanan said. 

There are kids around 

It is understandable that the Cobra Kai producers would want to maintain a wholesome set. There are a lot of young actors on the show. Robby didn’t have many scenes with Anthony LaRusso (Griffin Santopietro), but many of the Miyagi-Do and Cobra Kai students were younger than Buchanan. 

Bert actor Owen Morgan was 14 when Cobra Kai began. Nathaniel actor Nathaniel Oh was only 12. Even as they got older, new young cast members joined. Buchanan has a lot of scenes with 15-year-old Dallas Dupree Young in season 4. So it’s for the best that someone reigned Buchanan in before Cobra Kai became a TV-M show.
