We naturally scoffed at the premise of Syfy Superman prequel Krypton, but it seems it’s much more than simple flashback. Not only has the David Goyer-produced series revealed a time-traveling premise, but also famous DC figures like Brainiac, Adam Strange, Hawkwoman and more.

The show’s Comic-Con 2017 panel brought with it a host of new details, most notably that the prequel element will be mixed with “a conspiracy from the present that’s traveled back in time to Krypton to prevent the birth of Superman.” That will include Adam Strange and Hawkwoman fighting to foil said plot, while Doomsday and Brainiac will also serve as villains in the first season.

Now confirmed for a 2018 premiere, Krypton stars Cameron Cuffe as Kal-El’s grandfather Seg-El, along with King Arthur star Georgina Campbell as Lyta Zod, a member of Krypton’s military caste and the daughter of General Alura Zod. Departed Game of Thrones star Ian McElhinney plays Val-El, grandfather of Seg-El, atop a supporting cast that includes Da Vinci’s Demons star Elliot Cowan and World War Z alum Ann Ogbomo, Rasmus Hardiker, Wallis Day and Aaron Pierre.

Set 200 years before (but not directly tied to) Man of Steel, so reads the Krypton synopsis:

Years before the Superman legend we know, the House of El was shamed and ostracized. This series follows The Man of Steel’s grandfather as he brings hope and equality to Krypton, turning a planet in disarray into one worthy of giving birth to the greatest Super Hero ever known.

The new series is executive produced by Man of Steel scribe David Goyer and directed by Peaky Blinders helmer Colm McCarthy, while Sleepy Hollow alum Damian Kindler serves as executive producer and showrunner. Goyer and Kindler rewrote the original pilot teleplay, itself co-penned by Goyer and Ian Goldberg.

Krypton will likely come forward with more official details in the next few months, so watch the latest teaser below and stay tuned.
