Per Entertainment Weekly:
On Thursday, Syfy unveiled a first look at the Superman prequel series’ take on the ruthless bounty-hunter Lobo, who will be played by The Fall’s Emmett J. Scanlan in the show’s forthcoming sophomore season. Possessing super-human strength, a genius level intellect in matters of warfare, and immortality, Lobo “will keep coming until the job is finished,” reads the official character description. “His word is the only thing that Lobo holds sacred; although, he’ll never violate the letter of an agreement, he might disregard its spirit from time to time.” (He also murdered his entire species, so there’s that too…)
The series takes place on the eponymous fictional planet, approximately 200 years before the birth of Kal-El / Superman and eventual destruction of the planet, focusing on his grandfather, Seg-El (Cameron Cuffe). Krypton premiered on March 21, 2018. Its first season consists of ten episodes. In May 2018, Syfy renewed Kryptonfor a second season, which is expected to premiere in 2019.
