With Krypton destabilized from mining of the planet's core, Jora-El, chief advisor to Krypton's supreme council, recommends the council give her control of the genetics codex. Before any action can be taken, soldiers led by General Zed, an old friend of Jora-El's, launch an uprising and arrest the councilors. Realising that Krypton is doomed, Jora-El steals the genetic codex sought by Zed and infuses them into the DNA of her infant daughter, Kira-El – the first naturally born Kryptonian child in centuries. Donning her old armor, Jora-El sacrifices her life to allow her daughter to escape on a preprogrammed spacecraft. Zed's rebellion is suppressed by the council and are sentenced to the Phantom Zone after being convicted of treason. Krypton explodes soon after.
