The film stars Kira Kosarin, Jack Griffo, Addison Riecke, Diego Velazquez, Maya Le Clark, Chris Tallman, and Rosa Blasi, reprising their roles as the Thunderman family.

Dana Snyder also reprises his voice role as Dr. Colosso, alongside a returning ensemble cast that includes Daniele Gaither, Harvey Guillén, Helen Hong, Tanner Stine, Kenny Ridwan, Audrey Whitby, Jake Borelli, Jeff Meacham, Michael Foster, Jamieson Price, and Paul F. Tompkins.

Following the success of the film, a spin-off and sequel series titled The Thundermans: Undercover was greenlit and premiered on January 11, 2025.

Three years after the events of the series finale, when meteors strike Metroburg, the Thundermans step in to save the citizens.

While Hank and Barb enjoy their return, and Billy and Nora look forward to a normal high school life, Max and Phoebe are determined to regain their superhero status.

After that, Max and Phoebe figure out the V-Team are villains, they go by themselves to their lab to try to capture them, but Dark Mayhem Jr., She-Crab, and Krondor catch them and tie them up.

Dark Mayhem Jr., She-Crab, and Krondor escape with the Power Plant and Max and Phoebe are still trapped in the mysterious place.

They end up feeding pieces of the blue part to Cherry, Oyster, Gideon, Principal Bradford, and Mrs. Wong, turning them into superheroes.

With Chloe's teleportation needing a recharge, right before the self-destruct, Hank punches the system, causing it to break and allowing them out.

The villains are detained as Strongdor and Krondor start to bond much to the annoyance of Dark Mayhem Jr. Later, Super President Kickbutt reinstates the T-Force since the rule they broke doesn't apply to supervillains posing as superheroes.

Unbeknownst to everyone, Dr. Colosso receives a mysterious message from an unknown being, promising a special assignment for him, leading into the events of The Thundermans: Undercover.

Trevor Kirschner had been hired to direct, with series creator and showrunner Jed Spingarn writing the screenplay, and Zack Olin and Shauna Phelan producing.
