The world of Percy Jackson and the Olympians is expanding in epic ways. At San Diego Comic-Con 2025, Disney+ unveiled major updates about the hit mythology-based series, including a long-awaited premiere date, an exciting first look at Percy’s brother, and the addition of two fan-favorite demigods in the upcoming third season.
First Look at Tyson, Percy’s Cyclops Half-Brother
Fans got their first glimpse of Tyson in an exclusive teaser that debuted during the panel. The beloved cyclops and Percy’s half-brother, portrayed by Daniel Diemer, was revealed in a sneak peek that showed off his kind-hearted personality—and some seriously cool mythological action.
The character will play a pivotal role in The Sea of Monsters, the second installment of the series, helping Percy on his dangerous quest to save Camp Half-Blood.
Comic-Con Panel Brings Demigod Energy
The Hall H panel at San Diego Comic-Con was packed with stars and surprises. Cast members Walker Scobell (Percy), Leah Sava Jeffries (Annabeth), Aryan Simhadri (Grover), Dior Goodjohn (Clarisse), and Daniel Diemer (Tyson) appeared alongside executive producers Jonathan E. Steinberg, Dan Shotz, and Craig Silverstein.
Moderated by Timothy Simons (Tantalus), the panel gave fans a behind-the-scenes look at the making of Season 2, along with a teaser packed with monsters, quests, and new alliances.
Season 3 Casts Nico and Bianca di Angelo
In a surprise video message, creator Rick Riordan announced the casting of two beloved characters for Season 3: Nico and Bianca di Angelo, the children of Hades. Levi Chrisopulos will join the cast as Nico, while Olive Abercrombie takes on the role of Bianca in a recurring capacity.
These additions mark a darker turn in the story as the world of Percy Jackson continues to grow more complex.
Season 2 Release Date and Season 3 Renewal
Disney+ officially announced that Percy Jackson and the Olympians Season 2 will premiere on Wednesday, December 10, 2025. The season will follow the events of The Sea of Monsters, as Percy, Annabeth, Grover, and Tyson set out to recover the Golden Fleece and protect Camp Half-Blood from new threats.
In an exciting show of confidence, Disney+ had already greenlit Season 3 nearly a year earlier, before Season 1 had even premiered. With fan anticipation still sky-high, the early renewal confirms what readers and viewers already suspected: Percy Jackson and the Olympians is here to stay.
