Percy Jackson and the Olympians Cast & Characters Guide (Full Breakdown)

If you’re watching Disney+’s Percy Jackson and the Olympians and keep thinking “Wait, who is that god again?” (or “Where have I seen this actor before?”), you’re in the right place. Below is a clean, spoiler-light cast and characters breakdown—organized by the world’s “factions” (Camp Half-Blood, Olympus, monsters, and the new faces in later seasons).

This guide covers the core trio, the campers, the gods, and the biggest newcomers introduced in Season 2—plus the officially announced characters coming in Season 3.

Cast at a glance

Official trailers

If you want the fastest “tone check” on the series, these two official trailers do the job: the Season 1 launch trailer (Lightning Thief era) and the Season 2 trailer (Sea of Monsters era).

The main trio (Percy, Annabeth, Grover)

Percy Jackson (Walker Scobell)

Percy is the audience’s “new kid” into the hidden world of Greek mythology. He’s smart, stubborn, funny under pressure, and constantly surprised that the gods seem to have the emotional maturity of reality TV villains. His biggest strength is also his biggest risk: Percy will jump into danger for someone he cares about, even when it’s a trap.

Annabeth Chase (Leah Sava Jeffries)

Annabeth is the planner. She’s the kid who has been training for this life and wants to prove she belongs in the arena of myths. Where Percy improvises, Annabeth calculates. When the quests get messy, she’s usually the one trying to turn chaos into a strategy.

Grover Underwood (Aryan Simhadri)

Grover is Percy’s best friend and protector—part satyr, part anxious mess, and 100% loyal. When the show needs heart, you’ll often find it in Grover’s choices: he feels responsible, he cares deeply, and he keeps showing up even when he’s terrified.

Camp Half-Blood (allies, rivals, and staff)

Luke Castellan (Charlie Bushnell)

Luke is the charismatic older camper who knows how everything works—combat, cabins, camp politics, and the unspoken rules of surviving gods. He’s also the character that reminds you the series isn’t only about monsters; it’s about betrayal, belief, and what happens when kids decide the “adult system” is broken.

Clarisse La Rue (Dior Goodjohn)

Clarisse is a tough, proud warrior—often aggressive, often underestimated, and almost always intense. She’s the kind of character who will bully you in one scene and make you respect her in the next.

Chiron / Mr. Brunner (Glynn Turman)

Chiron is the mentor figure at camp—calm, wise, and extremely aware that teenagers plus divine weapons equals chaos. He’s a stabilizing force in a world where “authority” is usually either absent or petty.

Dionysus / Mr. D (Jason Mantzoukas)

Camp’s director is, unfortunately, the god of wine with the energy of a guy forced to babysit on his day off. Mr. D is funny, unpredictable, and more observant than he wants anyone to realize.

Sally Jackson (Virginia Kull)

Sally is Percy’s mom and a major reason he doesn’t lose himself to the demigod life. In a story full of gods who act like they’re allergic to responsibility, Sally’s love and grit hit harder than most lightning bolts.

Gabe Ugliano (Timm Sharp)

Gabe is Percy’s stepfather and the human-world problem Percy can’t simply solve with a sword. He’s an important reminder that Percy’s “real life” complications don’t disappear just because monsters exist.

Olympus (gods and immortals)

A useful rule: in this universe, gods are not “nice.” Even the ones who help can be selfish, moody, and transactional. They’re powerful, ancient, and used to getting their way—so every scene with them tends to crackle with pressure.

Poseidon (Toby Stephens)

Percy’s father is a god with real affection for his kid… and a mountain of divine constraints. Poseidon is one of the few Olympians who can feel warm without losing that “I could drown this whole room” presence.

Zeus (Season 1: Lance Reddick; Season 2: Courtney B. Vance)

Zeus represents Olympian authority at its most intimidating—commanding, volatile, and absolutely convinced he’s right. Starting in Season 2, the role is played by Courtney B. Vance.

Hermes (Lin-Manuel Miranda)

Hermes is charming, clever, and complicated. He’s the god who can feel friendly in the moment… while still playing a long game. His relationship to Luke adds extra weight to every appearance.

Ares (Adam Copeland)

Ares is the god of war with a swagger that screams “human problems are entertainment.” When he’s on-screen, expect conflict—verbal, physical, or both.

Athena (Andra Day)

Athena is wisdom, strategy, and judgment all in one. For Annabeth, Athena isn’t just a goddess—she’s the impossible standard Annabeth has been trying to reach her whole life.

Hephaestus (Timothy Omundson)

Hephaestus brings “inventor-god” energy: craft, engineering, traps, and the kind of problem-solving that feels different from Olympian politics.

Hades (Jay Duplass)

Hades is the Underworld’s ruler—and the show plays him with a vibe that’s less “cackling villain” and more “fed up cosmic administrator.”

Monsters & myth threats

Alecto / Mrs. Dodds (Megan Mullally)

Mrs. Dodds is one of those early “welcome to the real world” shocks: she looks like a normal teacher until Percy learns what’s been hiding in plain sight.

Medusa (Jessica Parker Kennedy)

Medusa is one of the most memorable myth figures the series uses—and one of the smartest examples of how the show can make a monster feel like a person, not just a boss fight.

Echidna (Suzanne Cryer)

Echidna is a mythic threat with a parent’s calm certainty—except what she’s parenting is horror. When she enters the story, the danger tends to become direct and unavoidable.

Season 2 newcomers (Sea of Monsters era)

Season 2 expands the world fast: bigger quests, new mythic figures, and higher emotional stakes back at camp. Here are the most important new faces to know.

Tyson (Daniel Diemer)

Tyson is a Cyclops with a gentle nature and a massive impact on Percy’s story. His presence changes the team dynamic immediately—especially because not everyone at camp is ready to trust a Cyclops.

Thalia Grace (Tamara Smart)

Thalia is a major “big picture” character in the Percy Jackson universe. Her story ties directly into the camp’s safety and the looming prophecy vibes hanging over the demigods.

The Gray Sisters: Anger, Tempest, and Wasp (Sandra Bernhard, Kristen Schaal, Margaret Cho)

The Gray Sisters are mythological chaos in triplicate—three sisters who share an eye and a tooth. Any scene with them is basically a test of whether the heroes can outthink the weird.

Tantalus (Timothy Simons)

Tantalus brings a different flavor of danger: less “monster attack,” more “authority figure who makes everything worse.” He’s petty, cursed, and in the worst possible position to influence demigod morale.

Circe / C.C. (Rosemarie DeWitt)

Circe is the kind of myth figure who doesn’t need brute force to be terrifying. She’s polished, inviting, and dangerous in a way that feels modern.

Polyphemus (Aleks Paunovic)

Polyphemus is a Cyclops rooted in classic myth—a powerful, territorial threat connected to the Golden Fleece storyline.

Chris Rodriguez (Kevin Chacón)

Chris is a demigod who becomes more important as the camp’s loyalties start to fracture. If you’re tracking “who might switch sides,” keep him on your radar.

Alison Simms (Beatrice Kitsos)

Alison is a show-created character (not from the original books) who adds extra tension around the idea of “what demigods do after camp” and how resentment can become recruitment fuel.

Kronos (Nick Boraine)

Kronos is the looming nightmare behind the conflict: a Titan presence that turns personal betrayal into an existential threat.

Season 3 confirmed characters (Titan’s Curse era)

Disney+ has already confirmed Season 3 (based on The Titan’s Curse), and several key characters have been officially cast. Here’s the current confirmed lineup of new Season 3 faces.

Nico di Angelo (Levi Chrisopulos)

Nico is one of the most beloved characters in the entire franchise. His arrival signals that the story is moving into a darker, more prophecy-heavy phase.

Bianca di Angelo (Olive Abercrombie)

Bianca is Nico’s older sister, and her choices have huge ripple effects in the larger Percy Jackson story.

Artemis (Dafne Keen)

Artemis is the goddess of the hunt and moon, and she brings a different kind of Olympian energy—disciplined, powerful, and not interested in playing nice for mortals.

Zoë Nightshade (Saara Chaudry)

Zoë is tied closely to Artemis and the Hunters. Expect a serious warrior presence with history behind her eyes.

Aphrodite (Kate McKinnon)

Aphrodite is the goddess of love and beauty—and she’s famous for appearing differently depending on who is looking at her. In this era of the story, she tests whether Percy understands the power of love before helping him.
