In 2005, author Rick Riordan released the first entry in a new fantasy-adventure book series inspired by Greek mythology. That first book was called The Lightning Thief, and after hitting bookstore shelves around the world, it quickly became a smashing success, beginning the Percy Jackson & the Olympians franchise. The series revolves around the titular Percy Jackson, a twelve-year-old boy who discovers that he’s secretly a demigod. Percy’s father is Poseidon, the Greek god of the sea, a stunning revelation that changes his life forever as he embarks on a journey to embrace his identity and become a hero.

The book series has been adapted before, with its first two novels, The Lightning Thief and Sea of Monsters, receiving film adaptations in 2010 and 2013, respectively. However, they both got mixed reviews from audiences, critics, and fans of the source material (not to mention Riordan himself), resulting in the film series being cut short. Fortunately, the books now have a shot at earning on-screen redemption as they’re being adapted again, this time as a TV show!

Percy Jackson and the Olympians will begin streaming on Disney+ on Wednesday, December 20, 2023. With the series' first season adapting The Lightning Thief, we’re about to meet a large mix of heroes and villains taken straight from the pages of Riordan's beloved novel. So, before jumping into this insane world of Greek gods and monsters, why not familiarize yourself with everyone first? Keep reading below for our handy cast and character guide for the series!

Walker Scobell as Percy Jackson

As mentioned above, Percy’s life gets turned upside down when he learns about his godly heritage. Being the son of Poseidon, he becomes a target for monsters, and so, his mother realizes that living in New York is no longer safe for him. She sends Percy to Camp Half-Blood, a protected community for Greek demigods to learn about their history and train to defend themselves against monsters. As if this drastic change wasn’t enough to deal with, Percy also gets accused of stealing Zeus’s thunderbolt, sending him on a dangerous quest across the country to retrieve it.

This will be Walker Scobell’s first time starring in a TV series but the young actor has already made a mark on audiences with his roles on the big screen. In 2022, Scobell appeared in films such as The Adam Project and Secret Headquarters, the former being his first-ever on-screen role, appearing alongside Ryan Reynolds.

Leah Sava Jeffries as Annabeth Chase

Annabeth is a daughter of Athena, the goddess of wisdom. Prior to Percy’s arrival at Camp Half-Blood, she had already been living and training there for five years. Being a skilled fighter, she accompanies Percy on his quest to find Zeus’s missing thunderbolt. Annabeth plays a crucial role in helping introduce Percy to his new responsibilities as a demigod, discovering his hidden abilities as the son of Poseidon, and navigating a dangerous world full of monsters.

Leah Sava Jefferies has recently appeared in films such as Beast and Something from Tiffany’s. She has also starred in TV shows such as Empire and Rel.

Aryan Simhadri as Grover Underwood

Grover is Percy’s best friend, who is a satyr, a half-human half-goat nature spirit. He was originally assigned to watch over Percy while living in New York. As a satyr, Grover is deeply passionate about nature. He can also sense the emotions of demigods and monsters, making him an essential companion for Percy’s quest to find Zeus’s thunderbolt. Grover takes advantage of this journey to try searching for Pan, the lost god of the satyrs, the wild, and folk music.
