Krypton - Other versions - Netflix
In a 2001–2002 storyline, Superman visited a version of Krypton which resembles the Silver Age version of the planet. However, unlike the Silver Age incarnation of the planet, this version includes “Eradicator assassins”, giant robots used by General Zod and the Science Council as part of “the Eradicator solution”, and later by Jor-El against Kryptonian religious zealots. Superman eventually discovered that this version of Krypton had been created as a trap for him by the villainous Brainiac 13, using the Eradicator Matrix, which he had stolen from the true Krypton along with Jor-El's diaries. The Eradicator Matrix is described as having been “designed to save Krypton by transforming a nearby husk of a planet into a habitable paradise”; Brainiac 13 uses it to transform a planet in the Phantom Zone into a replica of Krypton based on Jor-El's favorite period in Kryptonian history, and its inhabitants into Kryptonians. In Action Comics #850, a flashback shows Jor-El muttering about “damned Eradicators” while preparing to send Kal-El into space.
