Percy Jackson and the Olympians debuts on Disney+ with a two-episode premiere on December 20—and whether you’re a longtime reader or just diving in, this Percy Jackson characters guide will help you get to know the key players in this mythological adventure.
Who is Percy Jackson
Percy (Walker Scobell) is a 12-year-old struggling with ADHD, dyslexia, and a knack for attracting mythological chaos. After discovering he’s the demigod son of Poseidon, he’s thrust into a world of gods, monsters, and a stolen lightning bolt that could spark a divine war.
Annabeth Chase
The daughter of Athena, Annabeth (Leah Sava Jeffries) is intelligent, disciplined, and always five steps ahead. She’s the strongest warrior at Camp Half-Blood and is eager to prove herself by joining Percy on his quest.
Grover Underwood
Grover (Aryan Simhadri) is a loyal satyr disguised as Percy’s school friend. Though cautious, he’s deeply brave and dedicated to protecting Percy, making him an ideal companion for the quest.
Alecto aka Mrs. Dodds
Percy’s terrifying algebra teacher is actually Alecto, one of the three Furies serving Hades. Her monstrous transformation sets Percy’s journey into motion.
Sally Jackson
Sally (Virginia Kull), Percy’s mother, has done everything to protect her son from the truth of his origin. Her sacrifice to get him to Camp Half-Blood reveals her strength and unconditional love.
Chiron aka Mr. Brunner
Chiron (Glynn Turman), disguised as Mr. Brunner, is a centaur and the camp’s activities director. As a mentor and hero trainer, he provides Percy with moral guidance and mythological knowledge.
Dionysus aka Mr. D
Played by Jason Mantzoukas, Mr. D runs Camp Half-Blood with little patience and a lot of sarcasm. As Dionysus, he’s forbidden from drinking wine but finds other ways to bend the rules.
Gabe Ugliano
Percy’s stepfather Gabe (Timm Sharp) is selfish and abrasive, more interested in gambling than family. His negative energy ironically helps keep Percy hidden from monsters—until the truth emerges.
Clarisse La Rue
Dior Goodjohn plays Clarisse, the daughter of Ares. She’s tough, aggressive, and the camp’s top bully. Her confrontations with Percy create early tension in his new life.
Luke Castellan
Luke (Charlie Bushnell) is the charismatic leader of the Hermes cabin. As one of the few people to welcome Percy, he becomes a trusted guide—though his own story has unexpected turns.
