|Two hundred years before the time of Kal-El (Superman), the corrupt regime leading the city of Kandor on Krypton executes Val-El, grandfather of Seg-El, for treason. Seg and his parents are stripped of their privileges and banished to the lower class slums. Fourteen years later, chief magistrate Daron-Vex, the same man who condemned the Els, arranges a marriage between Seg and his youngest daughter Nyssa, which will allow Seg to be restored to the upper classes. Adam Strange, a man from Earth in the future, gives Seg a Sunstone with the El symbol and telling him to find the "fortress". Seg's mother Charys takes him to the hidden Fortress of Solitude, which contains Val-El's research. Val had discovered an alien threat to Krypton, but was silenced for it. Charys is arrested. Brought before the council, and refusing to reveal the Fortress, Seg's parents attack the guards, only to be killed by Jayna-Zod. Back at the Fortress, Adam tells a depressed Seg that the future is bright, but it is fading due to temporal meddling by a cosmic evil seeking to erase Superman.|

|Seg disregards Adam's warning and plans vengeance on Daron. However, Daron explains that Val was executed for his heretical belief in life existing far from Krypton, convincing Seg of Adam's warning. Seg brings a Science Guild data tablet to Adam and Kem for examination, but as the data disagrees with Val's research, Seg plans to kill Daron. Nyssa gives Seg his parents' ashes for closure, and to manipulate his trust. Seg uses his blood to open a DNA lock in the Fortress, activating a hologram of Val. Seg learns of Brainiac, a "world collector" with Krypton in its sights. While reviewing the data further, Kem and Adam find evidence of a scout probe, and deduce that Brainiac is already on his way. Jayna's daughter Lyta, disturbed by the Military Guild readying to purge the slums to weed out Black Zero terrorists, challenges Quex-Ul to the death for command.

This host—Seg's neighbor Rhom—is activated by Brainiac and begins killing soldiers in her path. The Sagitari use excessive force on the rankless to coerce information about the bodies, leading to officer Kol-Da killing an unarmed man. Lyta arrests her. Seg uses a shock grenade from Lyta to take down the fully infected Rhom, who is gathering data about Krypton and transmitting it to Brainiac. Seg reveals to Lyta that Val was right about a pending threat to the planet, and the two prepare to defend Krypton without the Council's interference.

Torn between her honor and her love for Lyta, Jayna is hesitant. The Commander, fully aware of Brainiac, captures and questions Seg, as he needs to dissect the sentry before it finds a new host. Kem tells Rhom's daughter Ona that Rhom is dying; Ona presents a statuette in offering to the Voice of Rao, who takes Ona as one of his disciples.

Syfy tweeted a debut of the show in 2018.

It was intended by the show's creators to be LGBTQ+ character, but this was only implied following alleged interference from former DC executive Geoff Johns. Cameron Cuffe was cast as Seg-El. Regé-Jean Page auditioned for the role but was not cast because Johns reportedly believed the character had to resemble Superman actor Henry Cavill due to initial fan perception that the show could serve as a possible prequel to the 2013 movie Man of Steel. Alongside Cameron Cuffe, other actors Ian McElhinney, Elliot Cowan, Ann Ogbomo, Rasmus Hardiker, Wallis Day, and Aaron Pierre were cast as Val-El, Daron-Vex, Jayna-Zod, Kem, Nyssa-Vex, and Dev-Em.

The first season holds a score of 60% on Rotten Tomatoes, based on 42 reviews, with an average rating of 6.26/10.

A 100% approval rating for the second season was reported by Rotten Tomatoes, with an average rating of 7.96/10 based on 10 reviews. Its critical consensus reads: "Fresh faces, exceptional performances, and a more clearly defined sense of purpose help Krypton find its footing".
