Percy Jackson Season 2: All the Confirmed New & Returning Cast & Characters

As the quest to find the Golden Fleece begins in the upcoming second season of Percy Jackson on Disney+, Camp Half-Blood and Mount Olympus are expanding with both familiar faces and exciting new additions. This season, which premieres on Disney+ on December 10, 2025, promises to raise the emotional stakes for not just Percy, but his friends Grover and Annabeth, as they brave the dangerous Sea of Monsters on a perilous, but vital, mission. Season 2 will see the return of beloved gods and mortals who shaped Percy’s journey in Season 1, alongside new characters from Greek mythology and the Percy Jackson and the Olympians book series by Rick Riordan. With the threat of Kronos still looming, the stakes are higher than ever, bringing together a talented ensemble cast for the next chapter of Percy’s epic saga.
