The Thundermans: Undercover

The Thundermans: Undercover shifts the established sibling dynamic into a new environment. Phoebe and Max arrive in a seaside town to address a local threat, but the stakes change when they take on the role of guardians to their younger sister, Chloe. The series pivots from a typical home life to a mission where the characters must balance investigating suspicious school activity with the practical demands of parenting a growing superhero.

Kira Kosarin returns to the role of Phoebe, operating alongside her twin brother in an unfamiliar setting. The central conflict relies on the friction of their forced cooperation as they manage a teen superhero in training. While the twins contend with the usual rivalries and high-pressure assignments, the show focuses on how they mentor a younger sibling whose powers remain hidden from her peers. The result is a series about navigating adolescence while maintaining the secrecy required by their professional responsibilities.
