We’ve got our eye on Daniel Diemer!

Today, in Hall H at San Diego Comic-Con, Rick Riordan and Disney+ announced that Diemer will star as the cyclops Tyson in Season 2 of Percy Jackson and the Olympians. He joins Walker Scobell (Percy Jackson), Leah Sava Jeffries (Annabeth Chase), and Aryan Simhadri (Grover Underwood) as a series regular. The Disney+ Original series from Disney Branded Television and 20th Television will begin filming Season 2 next week in Vancouver.

The upcoming season is based on The Sea of Monsters, the second installment in Disney Hyperion’s best-selling book series by award-winning author Rick Riordan. Set a year after the events of Season 1, it finds Percy Jackson returning to Camp Half-Blood—only to find his world turned upside down. Percy realizes his friendship with Annabeth is changing, he learns he has a cyclops for a brother, Grover has gone missing, and camp is under siege from the forces of Kronos. Percy’s journey to set things right will take him off the map and into the deadly Sea of Monsters, where a secret fate awaits the son of Poseidon.

In a video message for those in attendance at San Diego Comic-Con, Rick Riordan said, “Daniel’s enthusiasm and talent bring a whole new dimension to Tyson, and it’s going to be incredible to see him in the second season. I can’t wait for you guys to meet him and welcome him to the Percy Jackson universe.”

Diemer, who also appeared via a special video message, added, “I am thrilled to step into the extraordinary universe of Percy Jackson and the Olympians. I’ve been a fan of the books since I was 10 years old, and it’s a dream come true to be part of this and embark on such an exciting adventure with all the cast and crew—and of course, the passionate fans. I can’t wait to bring Tyson to life and share this journey with you all.”

About Tyson

A young cyclops who grew up all alone on the streets, Tyson finds it difficult to survive in the human world. Shy and awkward, with a heart almost as big as he is, the fan-favorite character discovers that Poseidon is his father, which makes Percy Jackson his half-brother.
