Cobra Kai fans may still be reeling from the end of Season 4, which recently premiered this past weekend, but co-creators Jon Hurwitz and Josh Heald are already excited about what’s to come in Season 5.

The next season of Netflix’ The Karate Kid rebboot series has already been filmed, according to Entertainment Weekly, meaning there’s still much in store for the Miyagi-Do martial artists.

WARNING: MAJOR SPOILERS AHEAD FOR ‘COBRA KIA’ SEASONS 4 and 5

In a recent interview with Entertainment Weekly, co-creator Jon Hurwitz revealed that he’s been dying to include “Thunderstruck” by AC/DC in an episode of Cobra Kai, but executives have stopped him for over five seasons now.

Known for its throwback to the ’80s, Netflix‘s The Karate Kid reboot series, Cobra Kai, has a very eclectic soundtrack of hair rock, wailing guitars, and stadium anthems. After all, the original films featured many cheesy rock songs including “You’re the Best” by Joe Esposito and “The Moment of Truth” by Survivor.

“We had ‘Thunderstruck’ written into the script,” Hurwitz explained. “We’ve written ‘Thunderstruck’ into the script several times over the years, and we’ve never been able to afford it in that moment or to make that choice [to spend the money on it] right now.”

He revealed that a montage in Season 4 of Johnny Lawrence (William Zabka) training Daniel LaRusso (Ralph Macchio) in the Eagle Fang style was meant to have the AC/DC song playing in the background, but was scrapped to budgeting.

Music supervisor Michelle Johnson ended up using “Breakin’ Outta Hell” by the Australian rock band Airbourne, since it was such a sound-alike to AC/DC’s music.

“A lot of times we write things into the script, but sometimes we’ll write something into the script that we can’t afford,” Hurwitz said. “I mean, our fantasy is having the kind of music budget that would allow for us to have nonstop AC/DC and Bon Jovi and Guns N’ Roses.”

The Cobra Kai showrunner was thrilled he could include Motley Crue’s “Girls, Girls, Girls” in Season 5 however, incorporated into a scene in which Lawrence tries to recruit female martial arts students.

The overuse of European sound-alikes has become somewhat of a running joke between fans, however, with the comically uncanny songs adding to the series’ campy charm. The writers even wrote a joke into the series in which one character yelled at his neighbor to stop blasting “shitty Metallica,” only to be told that it was actually a European rock band named Exodus.

Exodus guitarist Gary Holt later commented on the song’s inclusion, writing, “RAD!! One of my favorite shows just threw a massive Exodus reference! So sick!”

New tensions were also alluded to between Danny and Johnny, as jealousy and mentorship of Miguel (Xolo Mariduena) will corrupt their patched-up relationship in Season 5.

“When Daniel starts making a connection with Miguel — who is one of the most important relationships in Johnny’s life and is a surrogate son, of sorts — Johnny starts feeling like this lifetime rival of his is potentially a new, better role model that Miguel is turning to instead of him,” Hurwitz teased in an interview with Digital Spy.

Chozen (Yuji Okumoto), a villain first introduced in The Karate Kid Part II, is also scheduled to have a larger role in Season 5 after reentering in Season 3.

“We obviously know that Chozen’s coming back into the fold,” co-creator Josh Heald revealed, “and Daniel, who we find at the ultimate depth of his loss, is feeling defeated and feeling like he made a deal with the devil.”

“From that alone, I feel like audiences can infer the energy with which Season 5 is going to begin,” Heald continued. “There are quite a bit of storylines that start spinning very fast and very aggressively as we enter next season.”

Fans are also eagerly awaiting a cameo from Hilary Swank, who played Julie Pierce in the lesser-known 1994 spinoff film The Next Karate Kid. It has yet to be confirmed if the actress will show up in the future, but showrunners confirmed that they are “big fans.”

“Julie Pierce is very much a character who exists in this world in this universe,” Heald teased. “We’ll have to wait and see, you know, when and if Julie enters our Cobra Kai story.”

No release date has been confirmed for Season 5 of Cobra Kai yet, but fans were just treated to 10 episodes of Season 4 on Dec. 30, 2021.
