Just a day away from its season finale, a drama series picked up a renewal today that ensures it will return for a second season. Syfy announced the pickup for the Superman prequel “Krypton,” which will air its season one finale this Wednesday, May 23.

The show’s second season is expected to bow in 2019. Based on DC characters, the series comes from Warner Horizon Scripted Television.

“Krypton,” which has averaged 1.8 million viewers L3 per week to date, is Syfy’s most-watched debut season among total viewers for an original series since “Ascension” in 2014, and the most-watched season for any scripted series on the network since “Defiance” in 2015.

“‘Krypton’ is set two generations before the destruction of Superman’s home planet,” Syfy notes in today’s announcement. “The series follows Seg-El (Cameron Cuffe), the legendary Man of Steel’s grandfather, as a young man who is faced with a life and death conflict — save his home planet or let it be destroyed to restore the fate of his future grandson. In Season 1, with Krypton’s leadership in disarray and the House of El ostracized, Seg found himself in a difficult position: redeem his family’s honor and protect the ones he loves, while being challenged by familiar DC characters Brainiac and Earthly time-traveler Adam Strange.”

“Krypton” joins an upcoming Syfy lineup that includes returning originals “Happy!,” starring Christopher Meloni and Patton Oswalt and returning for a second season in 2019; the hit fantasy series “The Magicians,” which was greenlighted for a fourth season for 2019; “12 Monkeys,” set to air its fourth season story conclusion this June; and the “Channel Zero” horror anthology series, which is set to air its fourth installment this fall.

Upcoming new originals include the fall 2018 space thriller “Nightflyers,” based on author George R.R. Martin’s novella, and “Deadly Class,” based on the critically acclaimed Image Comics graphic novel of the same name.

Based on characters created by Jerry Siegel and Joe Shuster, “Krypton” is executive produced by David S. Goyer (“Man of Steel,” “Batman v Superman: Dawn of Justice”) through his Phantom Four banner, along with Cameron Welsh, who serves as showrunner.
