If you grew up watching Max and Phoebe battle it out in their Hiddenville basement, seeing them pop back up on Nickelodeon in 2025 probably felt like a fever dream. But the The Thundermans Undercover cast isn't just a simple "get the band back together" reunion. It’s actually a pretty bold shift for the franchise. Instead of the whole family crowding the kitchen, the show zeroes in on a specific trio—Phoebe, Max, and their little sister Chloe—moving them to a coastal town called Secret Shores.
Honestly, the dynamic is different this time. You’ve got the older twins basically acting as "parent-guardians" while trying to stop a new Villain League. It’s weird seeing them in a position of authority, but it works.

Who is actually in the The Thundermans Undercover cast?
Let's clear the air because people keep asking if the whole family moved to the beach. They didn't. This is a spinoff, not just Season 5. While the original series was a massive ensemble, this new chapter focuses heavily on the "Thunder Twins" and the youngest sibling.
Kira Kosarin and Jack Griffo are back as Phoebe and Max. They aren't just acting, though; both are heavily involved behind the scenes. Seeing them step into executive producer roles feels like a natural evolution. Then you have Maya Le Clark as Chloe. She was just a kid when the original show ended, but now she’s the heart of the show, dealing with high school drama and powers that occasionally go haywire.
The New Faces in Secret Shores
Because they moved to a new town, the show had to bring in some fresh blood. It's not just the classic Hiddenville crew anymore.
- Nathan Broxton as Jinx: He’s one of Chloe’s new best friends. He’s skeptical, funny, and honestly brings a grounded energy that the show needed.
- Kinley Cunningham as Booch: The other half of Chloe's new social circle.
- John Murphy as Superintendent Ferguson: Every Nick show needs a foil for the kids, and Ferguson is the guy. He’s the superintendent of the schools in Secret Shores and has a reputation for being... well, a bit of a nightmare.
Why the cast feels so different this time
In the original run, the chaos came from having six super-powered people under one roof. In the The Thundermans Undercover cast setup, the tension is more about the "secret" part of the title. Phoebe and Max are working jobs at the school to keep an eye on things. Phoebe is trying to be the "responsible" one (no surprise there), while Max is trying to prove he’s still got that edge, even though he’s technically a hero now.
We do see the rest of the family, but they aren't the main course. Chris Tallman (Hank) and Rosa Blasi (Barb) show up, but they’ve stayed behind in Hiddenville for the most part. It makes the moments when they do appear feel more special.
What happened to Billy and Nora?
This is the big question. Diego Velazquez (Billy) and Addison Riecke (Nora) are still part of this universe, but they aren't living in the Secret Shores beach house. They stayed in Hiddenville to live a "normal" high school life, which was a major plot point in the 2024 movie The Thundermans Return.
The Villains and Guest Stars
You can’t have a Thundermans show without some weird villains. The The Thundermans Undercover cast includes some really fun guest spots that keep the energy high.
- Gabrielle Nevaeh Green as Kiefer: She’s the lead henchman for a mysterious new villain called Mastermind. She’s essentially a recruiter for the new Villain League.
- Ryan Ochoa as Malware: Fans of Disney XD might recognize him, but here he’s playing a tech-based villain with a sentient gauntlet.
- Lilimar Hernandez as Kitty Klaw: A cat-themed thief who shows up to audition for the Villain League.
And yes, Dana Snyder is still the voice of Dr. Colosso. It wouldn't be the same without that snarky rabbit. Interestingly, the spinoff gives Colosso a bit more of a personal arc—he’s actually looking for a way to get his human body back through a mysterious deal.
Is the show actually good or just nostalgic?
It’s easy to write these reboots off as cash grabs. But the chemistry between Kira and Jack is still there. They’ve been friends for over a decade in real life, and you can tell. The show handles the "aging up" of the characters better than most. They aren't trying to act like they're 15 anymore. They're young adults with jobs, even if those jobs are just covers for the Hero League.
The seaside setting of Secret Shores also gives the show a different visual palette. It feels brighter and a bit more modern.
Actionable Steps for Fans
If you're looking to dive back into this world, there's a specific order you should follow to make sense of the The Thundermans Undercover cast and their current situation:
- Watch 'The Thundermans Return' (2024) first: This movie bridges the gap between the original series ending and the spinoff. It explains why the family is split up and how they got their "Z-Force" status back.
- Check out the 'Thundercover' Premiere: This is the first episode of the new series. It sets up the Secret Shores house and the new school dynamic.
- Keep an eye on the guest list: This show loves bringing back old characters like Cherry (Audrey Whitby) and Principal Bradford (Jeff Meacham). Don't blink or you'll miss a cameo.
The series is currently streaming on Paramount+ and airing on Nickelodeon. Whether you're a new fan or someone who watched the original pilot back in 2013, the new cast dynamic offers just enough change to keep the formula from feeling stale.
