Cast of The Thundermans: Actors and Characters List

If you grew up watching Nickelodeon in the 2010s, you likely remember Phoebe and Max Thunderman — the twin sibling duo whose superpowers could level a city block. The show ran for four seasons and 98 episodes from 2013 to 2018, building a devoted following that grew up alongside the actors. Fresh interest arrived with The Thundermans Return on March 7, 2025, reuniting the original cast for fans.

Lead Actress: Kira Kosarin as Phoebe Thunderman · Lead Actor: Jack Griffo as Max Thunderman · Nora Thunderman: Addison Riecke · Billy Thunderman: Diego Velazquez · Primary Cast Count: 7 main actors

The table below lists the main Thundermans cast with their character names and verified birthdates from Famous Birthdays and YouTube sources.

Why did Kira Kosarin quit acting?

Kira Kosarin played Phoebe Thunderman from 2013 to 2018, appearing in all 98 episodes of the series Wikipedia. After the show ended, she stepped back from television acting — she never announced a formal retirement, but she’s pursued music, social media content creation, and modeling work rather than taking new acting roles.

A YouTube video titled “Kira Kosarin on why she quit acting” has circulated online, reportedly featuring her own explanation of her career shift. However, the video falls into tier-3 sourcing, which means the specific quotes and details warrant some caution about precision. In general terms, Kosarin has described wanting to explore creative paths outside the structured audition-and-set cycle that child acting involves.

As of 2026, she was listed as 28 years old on aggregate age databases — a figure that aligns with her 1997 birthdate Famous Birthdays. She appeared in The Thundermans Return in March 2025, so she hasn’t fully severed ties with the franchise. The practical takeaway: Kira Kosarin didn’t quit acting in the dramatic sense — she shifted away from full-time television acting into other creative work.

The broader cast after Thundermans

The child actors have largely moved in different directions. Jack Griffo continued acting and pursuing music. Addison Riecke and Diego Velazquez have stepped back from public-facing work. Maya Le Clark, who played youngest sister Chloe, was reportedly 4 years old when she joined in season 3 around 2015 — she’s still a teenager as of 2026.

How old is Chloe in The Thundermans?

Chloe Thunderman is portrayed by Maya Le Clark, who was born March 28, 2011, making her around 14 years old in 2026. She appeared in 55 episodes across seasons 3 and 4, joining the show when she was approximately 4 years old YouTube Age 2025.

Within the show’s fiction, Chloe is the youngest sibling in the Thundermans family. Her character has laser eyes, fitting the pattern where each Thundermans child has a distinct power — Phoebe has telepathy, Max has evil ray vision, Nora has laser eyes, Billy has superspeed, and Chloe rounds out the group with her own laser ability.

The exact fictional age of Chloe within the show’s timeline isn’t explicitly stated in the main credits or Wikipedia character listings, which means the precise “in-show age” falls into the unclear category alongside some other character details. What sources confirm: Maya Le Clark was 4 when she joined around 2015, and she appeared in 55 episodes YouTube Age 2025.

Are Nora and Billy Thundermans twins?

Nora and Billy are not twins in the show — Nora is the older of the two, while Billy is the youngest male sibling. Addison Riecke plays Nora Thunderman, and Diego Velazquez plays Billy Thunderman. In real life, the two actors are not related — all siblings in the Thundermans family are fictional relationships Yen.com.gh.

Addison Riecke was born January 26, 2004, and Diego Velazquez was born December 5, 2001, making Riecke roughly three years younger in real life despite playing the older sibling on screen. When the series started in 2013, Diego was about 11 and Addison was about 9 years old.

The show treats Nora as the middle child and Billy as the youngest brother, a setup that places Nora above Billy in the family hierarchy on screen while the actor age gap runs in the opposite direction. Billy’s power is superspeed, while Nora shoots laser beams from her eyes.

The implication: The Thundermans casting deliberately mismatched actor ages with character positions, a standard Nickelodeon practice for finding the right chemistry on screen.

Why does Max turn evil?

Max Thunderman is Phoebe’s twin brother, and within the show’s fiction, he has an ongoing internal conflict between wanting to be a good superhero like the rest of the family and being drawn to supervillainy. Jack Griffo plays Max, and this character arc — Max drifting toward evil — runs through much of the series Famous Birthdays.

The show frames Max’s villainous impulses as a phase he’s working through, with the family generally expecting he’ll outgrow them. Max has the power of an “evil ray” that can turn people bad, which puts him at odds with Phoebe, who has telepathic abilities and typically serves as the moral anchor of the sibling pair.

Phoebe and Max are twins in the show, but Kira Kosarin and Jack Griffo have no real-life relation — they’re not twins, and they’re not related at all Yen.com.gh. The twin dynamic on screen is entirely fictional.

The villain arc in context

Max’s evil-turning storyline reflects a common Nickelodeon sitcom pattern: a character has a trait that should make them a villain but instead learns to use it responsibly. Max’s “evil ray” vision creates comedy and conflict without ever fully committing him to villain status — the show keeps the door open for redemption arcs across its 98 episodes.

What this means: The Thundermans writing team used Max’s powers as a recurring plot device rather than a permanent character transformation, keeping him sympathetic while generating season-long tension.

Who is older, Phoebe or Max?

Phoebe and Max are portrayed as twins in the show, which means neither is definitively older — they share the same birthdate within the fictional Thundermans family. Kira Kosarin (Phoebe) was born October 7, 1997, and Jack Griffo (Max) was born December 11, 1996, making Griffo nearly 14 months older in real life YouTube birthdate sources.

The show presents them as simultaneous births — twin siblings — and doesn’t establish a birth-order hierarchy between them. Phoebe tends to take on more responsibility as the older-sibling type despite the fictional equality, which is part of her character as the family’s conscience.

This is one of those cases where the actor’s real age and the character’s fictional position don’t align cleanly. Kira Kosarin is the older actor by about a year, but her character shares equal standing with Max on screen.

What the actor ages mean for the show

• Kira Kosarin was 16 when filming began in 2013 YouTube Then and Now 2026.
• Jack Griffo was also 16 when filming began in 2013 and 21 when filming ended in 2018 YouTube Real Age.
• The 2013–2018 production span gave the twin actors a five-year window together on set.

The pattern: Viewers searching “who’s older” likely expect a simple answer, but the Thundermans case demonstrates how child acting casting often prioritizes on-screen chemistry over real-world age accuracy.

The Thundermans cast built something that holds up — four seasons and 98 episodes of a superhero family comedy, with actors who grew up on screen together. The reunion film in 2025 proved there’s still an audience, and the fact that the main cast appeared in The Thundermans Return suggests the door for future projects isn’t closed.
