“The Vampire Diaries” alum Shaun Sipos has joined the cast of Syfy’s “Krypton.”

According to Deadline, Sipos will play the series regular role of Adam Strange, a world-weary human, who finds himself stranded on Krypton and becomes the unlikely mentor to Superman’s grandfather, Seg-El (Cameron Cuffe).

Developed by Goyer and Damian Kindler, “Krypton” is set two generations before the destruction of the titular home planet of Superman. It follows the story of Seg-El, the scion of the once-prosperous House of El that’s stripped of its rank after it failed to end tyranny. When the series begins, Seg-El lives in the planet’s lowest caste and fights to redeem his family’s honor and save his planet from chaos.

“The show really is about the forces trying to destroy the House of El, both good and bad,” DC comics boss Geoff Johns said (via SYFY WIRE) during the show’s panel at the San Diego Comic-Con last July. “But there’s also another house that plays a major role in the past that is integral to the House of El, the House of Zod.”

Johns also revealed during the panel that Adam is actually from the future. That interesting detail was made public when Johns recited the character’s first lines after he lands on the Krypton of the past: “I’m from a planet called Earth. My name is Adam Strange. I come from a time long after this, and I need you to help me save the legacy of your grandson.”

Adam was just one of the several popular DC Comics characters announced at Comic-Con as upcoming additions to Krypton. Other characters that are confirmed to appear on the show include Seg’s father Ter-El, Hawkwoman, Brainiac and Black Mercy.

Goyer told Den of Geek last July that they decided to add unexpected characters to the series to make it more exciting especially for DC fans, who already know the ins and outs about the Man of Steel’s home planet.

“[‘Krypton’ features] a lot of other characters from the Superman canon, some of which have been linked to Krypton before, some of which haven’t, that are also included,” Goyer said. “[But] there are also some other DC Universe characters that aren’t specifically part of the Superman canon that will play a role. We’re definitely doing some things that I think people won’t expect. We’re making some unexpected additions to this Superman world that I’m excited for audiences to see.”

Aside from his recurring role as Aaron Whitmore on “The Vampire Diaries,” Sipos is also known for his performances on “Complete Savages,” “Life Unexpected,” “Melrose Place” and the recently cancelled “Dark Matter.”

“Krypton” will premiere on Syfy sometime next year.
