‘Percy Jackson’ Season 2 gets premiere date — Season 3 casts fan-favourites Nico and Bianca

Disney+ has set December 10 as the premiere date for season two of Percy Jackson and the Olympians, the fantasy series based on Rick Riordan’s bestselling books. The announcement came Thursday during the show’s panel at San Diego Comic-Con, which also included a teaser trailer and news about future casting.

The upcoming season adapts The Sea of Monsters, the second book in Riordan’s series. In a video message to fans, Riordan confirmed the date and previewed the introduction of Tyson, a Cyclops and Percy’s half-brother, played by The Half of It actor Daniel Diemer. A brief glimpse of a chariot race scene at Camp Half-Blood was also included in the teaser.

Executive producer Craig Silverstein praised the production scale, saying the chariot track was “the most amazing set I’ve been on in my whole career.” Actor Timothy Simons, who plays Tantalus in season two, joked about the show’s budget, referencing its “fire budget” for effects-heavy scenes.

The panel also offered a major update on season three. Riordan revealed that two fan-favorite characters from the books — Nico and Bianca di Angelo — have been cast. Levi Chrisopulos will play Nico as a series regular, while Olive Abercrombie will recur as Bianca. Chrisopulos has stage experience in Peter Pan and a guest role on FBI, while Abercrombie previously appeared in Mayfair Witches and Outer Range.

Season three will adapt The Titan’s Curse, with production expected to begin soon.

In addition to Scobell and Diemer, the panel featured series stars Leah Sava Jeffries, Aryan Simhadri, Charlie Bushnell, and Dior Goodjohn, alongside executive producers Jonathan E. Steinberg, Dan Shotz, and Silverstein. Riordan and his wife Rebecca remain closely involved as executive producers.
