The cast of Percy Jackson and the Olympians TV series has become one of the most recognisable young ensembles in fantasy television. The Disney+ adaptation brings Rick Riordan’s famous demigod characters to life while combining experienced actors with a talented group of younger performers.
Walker Scobell leads the series as Percy Jackson, with Leah Sava Jeffries as Annabeth Chase and Aryan Simhadri as Grover Underwood. Together, the three form the central trio at the heart of Percy’s adventures.
As the story has progressed, the Percy Jackson cast has expanded considerably. Season 2 introduced important characters such as Tyson, Thalia Grace, Athena and Zeus, while Season 3 brings even more familiar faces from Rick Riordan’s books to the screen.
Walker Scobell as Percy Jackson
Walker Scobell plays Percy Jackson, the central character of the series. Percy is a young demigod who discovers that his father is Poseidon, one of the three major Olympian gods.
Scobell carries much of the show’s emotional and action-driven storyline. His performance combines Percy’s humour, loyalty and uncertainty as he learns more about the dangerous world surrounding him.
The role requires Scobell to handle everything from monster battles to emotional family moments. His performance has helped establish the television version of Percy as a character who feels both heroic and relatable.
Leah Sava Jeffries as Annabeth Chase
Leah Sava Jeffries plays Annabeth Chase, the daughter of Athena and one of Percy’s closest friends. Annabeth is intelligent, determined and highly knowledgeable about the world of Greek mythology.
Jeffries brings confidence and emotional depth to the character. Her relationship with Percy develops throughout the series, making Annabeth an important part of both the adventure and the personal story.
Annabeth’s strategic thinking also gives the main trio a different kind of strength. While Percy often acts quickly, Annabeth tends to analyse situations before deciding what to do.
Aryan Simhadri as Grover Underwood
Aryan Simhadri plays Grover Underwood, Percy’s loyal best friend and a satyr. Grover becomes an essential member of Percy and Annabeth’s adventures.
His character often provides humour, but Grover is much more than comic relief. He is brave, caring and deeply committed to protecting his friends.
Simhadri’s performance gives Grover a warm personality that balances the more intense moments of the story. His friendship with Percy remains one of the series’ strongest relationships.
Charlie Bushnell as Luke Castellan
Charlie Bushnell plays Luke Castellan, an older demigod at Camp Half-Blood. Luke initially appears as an experienced and supportive figure for Percy.
However, his character becomes increasingly important as the larger conflict develops. Luke’s relationship with Percy adds another layer to the story because he represents both friendship and betrayal.
Bushnell brings a complicated quality to Luke, allowing the character to appear sympathetic while still carrying a much darker role within the wider mythology.
Dior Goodjohn as Clarisse La Rue
Dior Goodjohn plays Clarisse La Rue, the daughter of Ares. Clarisse is known for her confidence, aggressive personality and strong competitive streak.
Although she initially clashes with Percy, her character becomes more important as the story moves forward. Clarisse represents the tougher side of life at Camp Half-Blood.
Goodjohn gives the character plenty of energy while also showing that Clarisse has motivations and vulnerabilities beneath her intimidating personality.
Daniel Diemer as Tyson
Daniel Diemer joined the main cast as Tyson, Percy’s cyclops half-brother. Tyson becomes particularly important during the second season, which adapts the events of The Sea of Monsters.
Tyson is physically powerful but also innocent and kind-hearted. His relationship with Percy creates several emotional moments because Percy must learn what it means to have a family member he did not know existed.
Diemer brings warmth to Tyson while also handling the character’s more dramatic scenes.
Tamara Smart as Thalia Grace
Tamara Smart plays Thalia Grace, a significant demigod connected to the larger history of Camp Half-Blood. Her character becomes increasingly important as the story expands beyond Percy’s original quest.
Thalia adds another perspective to the mythology surrounding the demigods. Her arrival also helps connect the current storyline with events that happened before Percy discovered his own identity.
Smart continues into the show’s third season, where Thalia becomes part of a much larger adventure.
The Adult Cast of Percy Jackson and the Olympians
The cast of Percy Jackson and the Olympians also includes numerous experienced actors who portray gods, parents, mentors and other important characters.
Virginia Kull plays Sally Jackson, Percy’s mother. Glynn Turman portrays Chiron, the mentor and trainer at Camp Half-Blood. Jason Mantzoukas plays Dionysus, also known as Mr. D, while Toby Stephens portrays Poseidon.
The series has also featured Adam Copeland as Ares, Lin-Manuel Miranda as Hermes and Andra Day as Athena. Courtney B. Vance plays Zeus in the later seasons.
These performances give the series a strong adult ensemble and help make the mythology feel larger than the young heroes’ immediate adventures.
Who Is Joining the Percy Jackson Cast in Season 3?
Season 3 expands the cast again as the television adaptation moves into The Titan’s Curse. The season is scheduled to premiere on Disney+ on 20 November 2026.
One of the most anticipated additions is Levi Chrisopulos as Nico di Angelo. Olive Abercrombie plays his sister Bianca di Angelo. Both characters are children of Hades and become important figures in the next stage of Percy’s story.
Dafne Keen joins the cast as Artemis, while Saara Chaudry plays Zoë Nightshade. These characters are central to the Hunters of Artemis storyline and introduce a new group of personalities to the series.
Season 3 therefore gives the Percy Jackson TV cast a noticeably wider scope. Percy, Annabeth and Grover remain at the centre, but the story begins bringing more demigods and mythological figures into their world.
Why the Percy Jackson Cast Works So Well
One of the biggest strengths of the series is the balance between its younger leads and established supporting actors. Walker Scobell, Leah Sava Jeffries and Aryan Simhadri give the show its youthful energy, while the adult cast provides experience and dramatic weight.
The chemistry between the main trio is especially important. Percy, Annabeth and Grover have different personalities, but their differences make their friendship believable.
The expanding ensemble also allows the series to explore more of Camp Half-Blood. Each new character introduces another part of Greek mythology, giving the show more opportunities for adventure, conflict and character development.
Percy Jackson and the Olympians Season 3 Cast
The third season is expected to be one of the biggest chapters of the series so far. It adapts The Titan’s Curse and introduces several characters who are important to the wider Percy Jackson story.
Walker Scobell returns as Percy Jackson, while Aryan Simhadri returns as Grover Underwood. Charlie Bushnell continues as Luke Castellan, and Tamara Smart returns as Thalia Grace. Levi Chrisopulos and Olive Abercrombie join them as Nico and Bianca di Angelo.
Leah Sava Jeffries also remains part of the series as Annabeth Chase. Her character becomes particularly important as Percy faces a new challenge involving her disappearance.
The new season therefore continues the show’s main relationships while introducing a new generation of characters who could become important to the future of the series.
Conclusion
The cast of Percy Jackson and the Olympians TV series has grown from a small group of young heroes into a much larger ensemble of demigods, gods, monsters and legendary figures.
Walker Scobell, Leah Sava Jeffries and Aryan Simhadri remain the heart of the show as Percy, Annabeth and Grover. Around them, actors such as Charlie Bushnell, Dior Goodjohn, Daniel Diemer and Tamara Smart have helped expand the story.
With Season 3 introducing Nico, Bianca, Artemis and Zoë Nightshade, the Percy Jackson cast is becoming even more ambitious. The upcoming season should give fans a chance to see a wider part of Rick Riordan’s mythology brought to life on screen.
