Similarly to origins since The Adventures of Superman (radio) and More Fun Comics #101 his wife refuses to leave him and instead only agrees to put their son into the rocket. After rocket was successfully launched it passed through warp anomaly in space and landed on (John Byrne-esque) Krypton where it is found by Jor-El a rebelleous in his views scientist and Lara, who is at first is his reluctant guest, that closely follows norms of their society and opposes him at every stance. They name him Kal-El, a 23rd heir for the House of El. Because Krypton's gravity is heavier the child is sent into the special liquid chamber where he will get slowly adapted towards current harsher environment. As Kal grows up he has to wear special exo-suit that lets him walk, run and even jump considerably high on Krypton. Until he finds Green Lantern Power battery along with the ring which grants him ability to fly and makes solid constructs using his will. Armed with power ring he prevents Krypton from explosion by stabilizing its core. Later on he learns that he isn't from Krypton, travels to OA which assign him for Sector 2814, after which finally returns to his birthplace on planet Earth where he witnessing that such landmarks from normal timeline as Themyscira, Atlantis and Gotham City were completely destroyed while only city that remained was Metropolis. In Metropolis, he without knowing it yet, meets his own biological mother Martha, as well as Perry White, Lois Lane and Jimmy Olsen who are in this continuity part of resistance against tyranical fascist organization led by this version's Lex Luthor. As newly assigned Green Lantern of sector 2814 he helps rebels defeat Luthor's army but power in his ring runs out quickly, after which he gets captured by Luthor's forces. Lois Lane and Jimmy Olsen while trying to smuggle into Kal-El's cell the Power Battery but got captured by Luthor's men as well. While in the fit of rage and frustration Kal-El discovers that despite being Human like rest of the people on this planet he is actually super strong, his skin is imprevious towards assault rifle bullets and he also can successfully survive high voltage electrocution due to living in much harsher conditions of Krypton all these years.
