As Season 2 of Percy Jackson and the Olympians prepares for production later this year, we have exclusively learned that casting has begun on some fan-favorite characters, as well as an original character. We’ve heard they’re currently on the hunt for Percy Jackson’s (Walker Scobell) half-brother, Tyson, and the daughter of Zeus (Lance Reddick), Thalia, and a new demigod by the name of Alison.
They’re currently looking for actors of all ethnicities, between the ages of 15 to 18, for the role of Tyson who will be a series regular. The casting description for Tyson, describes him as big and tall, but with a heart just as big as he is. He is biologically 8 years old, but looks like a fully developed human teenager due to the Mist. His powers are invulnerability to fire, enhanced hearing, and ability to mimic voices.
Like Tyson, actresses between 15 to 18 of all ethnicities are being looked at for Thalia. She’s the daughter of Zeus who gave her life to protect her friends, 6 years prior to the series, but was saved by her father and turned into a tree. She has a tough and prickly personality and is described as being a punk or rebel. She will be a recurring guest star in Season 2, but with the potential for more in future seasons.
Deviating from the books, Season 2 will introduce Alison, who is described as being a rogue demigod and a member of Luke Castellan’s (Charlie Bushnell) army. She lives in the human world now, but attended Camp Half-Blood in her younger years. She will be a recurring guest star. Actresses between 18 to 22 of all ethnicities are being looked at for the role.
Tyson is introduced in the second book that the upcoming season will adapt, The Sea of Monsters. He plays a crucial role in the novel, joining Percy Jackson and Annabeth Chase (Leah Sava Jeffries) on their quest to save Grover (Aryan Simhadri) and find the Golden Fleece. Fans of the books know the character's significance, as he is revealed to be a son of Poseidon (Toby Stephens) and Percy's half-brother. Tyson's character is also essential to Annabeth’s traumatic past with his kind. This dynamic brings themes of overcoming prejudice, personal growth, and the importance of looking beyond superficial differences. This can set up a nuanced and challenging arc for Jeffries’ Annabeth to tackle.
Thalia Grace, daughter of Zeus, was mentioned and seen (yes, that oak tree protecting camp) in the first season by various characters. In the books, before arriving at Camp Half-Blood, Thalia, Luke, and Annabeth formed a tight-knit group, struggling for survival in the mortal world. Tragically, when they finally reached the camp, Thalia sacrificed herself and was turned into a tree by Zeus, her bravery ensuring the camp's protection. If they follow the novels closely in season 2, however, her tree will be poisoned, setting off a quest led by breakout character, Clarisse La Rue (Dior Goodjohn). By the end of the book, Thalia is brought back to human form and becomes a crucial figure in the prophecy as a "forbidden child" of the big three gods of Olympus.
