Following the success of its first season, which adapted Rick Riordan’sThe Lightning Thiefnovel to the small screen,Percy Jacksonseason 2 will tackle Riordan’sSea of Monsters.Percy Jackson’s cast of characterswill grow alongside the epic story, which made it even more exciting when Riordan shared thatDaniel Diemer will playPercy Jackson’s Tysonin the second season.
In addition to being the titular character’s half-brother,Tyson isPercy Jackson’s resident cyclops. Although Percy (Walker Scobell) and Tyson meet in New York City inSea of Monsters, the half-siblings soon find themselves at Camp Half-Blood, wherePoseidon officially “claims” Tyson as his own. However, things aren’t quite right. Someone has poisoned the tree of the demigod Thalia, which leaves the campers’ sanctuary vulnerable to attacks.

Percy Jackson Season 2’s Tyson Casting Hints At A Big Change To His Age
Tyson Actor Daniel Diemer Is Over A Decade Older Than Percy Jackson Actor Walker Scobell
AlthoughPercy Jacksonseason 2’s Tyson casting announcement was met with excitement, the reveal hints at a big change for the upcoming outing. Best known for roles in Alice Wu’s coming-of-age movieThe Half of It, Mike Flanagan’s horror seriesThe Midnight Club, Hulu’s crime dramaUnder the Bridge, Daniel Diemer has appeared in a wide variety of projects. At SDCC, Riordan told attendees thatDiemer “bring[s] a whole new dimension to Tyson” through his talent and enthusiasm. At 6’4”, there’s no denying that Diemer also has the right stature to play Percy’s cyclops half-brother.
…Percy and Tyson are supposed to be roughly the same age.

However, there is one element of the casting that’s worth flagging. Diemer, who was born in 1996, is 28 years old, while Walker Scobell, who was born in 2009, is 15 years old. InPercy Jackson and the Olympians: The Sea of Monsters, Percy and Tyson are supposed to be roughly the same age. Based on Diemer’s real-life age,it’s possible Tyson will be canonically older in the seriesas well. While Tyson becoming Percy’s older half-brother isn’t at the same level as thePercy Jacksonseason 1 endingtwist, it’s still an interesting development.

Making Tyson Older Than Percy Reverses A Major Poseidon Mistake
Tyson Being Percy’s Older Brother Means Poseidon Doesn’t Break His Oath (Again)
Although the Tyson of Riordan’s novel is roughly the same age as Percy, he comes across as a bit younger than his demigod half-brother. Before the duo head to Camp Half-Blood, Percy becomes Tyson’s protector, defending him from the ruthless bullies at school — sort of like a considerate older sibling. However, even if Tyson is just slightly younger than Percy, that impliesPoseidon broke his pact with Zeus and Hades— even after fathering Percy. However, if Tyson is older than his brother inPercy Jacksonseason 2, that meansPoseidon kept his oath after Percy’s birth.
