Cast of Percy Jackson and the Olympians TV Series Full Cast Guide

The cast of Percy Jackson and the Olympians TV series has become one of the most recognisable young ensembles in modern fantasy television. Based on Rick Riordan’s popular Percy Jackson books, the Disney+ series brings demigods, Greek gods, monsters and mythical adventures to life with a talented mix of young actors and established stars.

At the centre of the show are Walker Scobell as Percy Jackson, Leah Sava Jeffries as Annabeth Chase and Aryan Simhadri as Grover Underwood. Their characters form the heart of the story and face dangerous quests together at Camp Half-Blood.

As the series continues, the cast has also expanded with important characters such as Tyson, Clarisse La Rue, Luke Castellan and Thalia Grace. Season 3 adds further major characters from The Titan’s Curse, including Nico and Bianca di Angelo.

Main Cast of Percy Jackson and the Olympians TV Series

The main cast combines young performers with experienced actors who bring the world of Percy Jackson to life. Each performer has an important role in building the show’s version of the Greek mythology-inspired universe.

Walker Scobell as Percy Jackson

Walker Scobell plays Percy Jackson, the central character of the series. Percy is a young demigod and the son of Poseidon, the Greek god of the sea.

Scobell leads the series through Percy’s journey from an ordinary teenager who feels different from those around him to a hero discovering his abilities and his place in the world. Disney+ lists Scobell as one of the leading stars of the series.

Percy’s friendship with Annabeth and Grover is one of the most important parts of the show. Together, the three characters face monsters, gods and dangerous quests while trying to protect the people they care about.

Leah Sava Jeffries as Annabeth Chase

Leah Sava Jeffries plays Annabeth Chase, one of Percy’s closest friends and an important demigod at Camp Half-Blood.

Annabeth is the daughter of Athena, the Greek goddess of wisdom. She is intelligent, determined and highly capable, making her an important member of Percy’s team.

Jeffries returns as Annabeth in the later seasons, with the character becoming even more important as the story expands. Disney+ identifies Jeffries as one of the principal stars of the series.

Aryan Simhadri as Grover Underwood

Aryan Simhadri plays Grover Underwood, Percy’s loyal best friend and protector.

Grover is a satyr rather than a human demigod, which gives him a unique role within the story. He is closely connected to nature and often provides humour while remaining a brave and dependable member of the group.

Simhadri has remained part of the central cast as Percy and Annabeth continue their adventures. Disney+ lists him alongside Scobell and Jeffries among the show’s leading performers.

Charlie Bushnell as Luke Castellan

Charlie Bushnell plays Luke Castellan, an older demigod at Camp Half-Blood.

Luke initially appears as an experienced and helpful figure for younger campers. His relationship with Percy becomes increasingly important as the story develops.

Bushnell is part of the continuing ensemble and is also listed among the principal cast members connected with the show’s later seasons.

Dior Goodjohn as Clarisse La Rue

Dior Goodjohn plays Clarisse La Rue, a strong and competitive demigod at Camp Half-Blood.

Clarisse is the daughter of Ares, the Greek god of war. Her personality often creates tension with Percy, but her character also becomes an important part of the wider Camp Half-Blood story.

Goodjohn joined the main ensemble and returned for the show’s second season alongside the central cast.

Daniel Diemer as Tyson

Daniel Diemer plays Tyson, a cyclops who becomes particularly important in the second season.

Tyson is connected to Percy in a surprising way and plays a major role in the events inspired by The Sea of Monsters. Disney+ announced Diemer as a series regular for season two, alongside Scobell, Jeffries and Simhadri.

His addition gives the cast another important character from Rick Riordan’s books and expands the mythology surrounding Percy’s family.

Tamara Smart as Thalia Grace

Tamara Smart plays Thalia Grace, a daughter of Zeus who becomes increasingly important to the wider story.

Disney+ announced Smart as a recurring guest star for season two. Thalia is also part of the continuing story surrounding the demigods and the prophecy that shapes the Percy Jackson universe.

Smart has also been highlighted as part of the season three cast, showing the growing importance of Thalia in the television adaptation.

Nico and Bianca di Angelo

Season 3 introduces two major characters from the Percy Jackson books: Nico di Angelo and Bianca di Angelo.

Levi Chrisopulos plays Nico, while Olive Abercrombie plays Bianca. Disney+ announced both actors for season three, which adapts The Titan’s Curse.

Their arrival adds another important family to the story and opens the door to new mythology, relationships and conflicts.

Other Important Cast Members

The cast of Percy Jackson and the Olympians TV series also includes several established performers in roles connected to the gods, Camp Half-Blood and Percy’s family.

The wider ensemble has included performers such as Glynn Turman, Virginia Kull, Jason Mantzoukas, Lin-Manuel Miranda, Timothy Simons, Courtney B. Vance, Andra Day, Adam Copeland, Sandra Bernhard, Margaret Cho, Kristen Schaal, Rosemarie DeWitt and Toby Stephens.

Andra Day, for example, appears as Athena, Annabeth’s divine mother. Disney+ highlights her character in its season two cast guide.

These performers help expand the series beyond its central trio and give the world of Percy Jackson a larger sense of scale.

How the Cast Changes Across the Seasons

The cast develops as Percy’s story moves beyond the events of the first book. The first season establishes Percy, Annabeth and Grover while introducing Camp Half-Blood and the larger world of Greek mythology.

Season two expands the ensemble with characters such as Tyson and Thalia while bringing back the main characters. The season is based on The Sea of Monsters, the second book in Rick Riordan’s series.

Season three moves into The Titan’s Curse. Disney+ has confirmed characters including Nico and Bianca, while the main cast continues to return. The third season is scheduled to premiere on Disney+ on November 20, 2026.

Why the Cast Matters to the Series

The success of a fantasy adaptation depends heavily on its characters. Percy Jackson is not only about monsters and Greek mythology. It is also about friendship, family, identity and growing up.

Walker Scobell, Leah Sava Jeffries and Aryan Simhadri provide the central friendship that connects many of the show’s adventures. Around them, the expanding cast introduces new relationships and conflicts that allow the story to grow with each season.

The addition of characters such as Tyson, Thalia, Nico and Bianca also helps the television series explore more of the world created by Rick Riordan.

Conclusion

The cast of Percy Jackson and the Olympians TV series continues to grow as the Disney+ adaptation moves deeper into Rick Riordan’s story. Walker Scobell, Leah Sava Jeffries and Aryan Simhadri remain at the centre as Percy, Annabeth and Grover, while performers such as Charlie Bushnell, Dior Goodjohn, Daniel Diemer and Tamara Smart add important characters to the expanding story.

With season three adapting The Titan’s Curse and introducing Nico and Bianca di Angelo, the series is bringing even more characters from the books into its television universe.
