Editing Krypton (comics) (section)

====Destruction====
Though it survived the war, Krypton was scarred deeply by it. The formerly lush garden world was burned and blasted to a desert, and a sterile society—emotionally unlike its predecessor—emerged. The population lived isolated from one another in widely separated technological citadels, shunning all physical and personal contact, to the point that even family members would only interact with each other via communication devices. Procreation became a matter of selecting compatible genetic material to be placed within an artificial womb called a "birthing matrix"; the parents almost never met in person and never touched one another. The planetary government was deeply isolationist and forbade space exploration and communication with other worlds.

The young scientist Jor-El was born into this world. By his adult years, a mysterious "Green Plague" was killing Kryptonians by the thousands, and upon researching the matter, Jor-El discovered that its cause was growing radiation produced by Krypton's increasingly unstable core. This process was going to cause the planet to explode.

Unable to convince his associates to abandon tradition and consider escape, and reasoning that modern Kryptonian society had grown cold, unfeeling and sterile, Jor-El removed the Eradicator's planetary binding genes from his unborn son Kal-El's genetic pattern, took Kal-El's birthing matrix and attached a prototype interstellar propulsion system to the vessel.<ref name="actionannual2"/><ref name="worldofkrypton4">{{Cite comic | writer = Byrne, John | penciller = Mignola, Mike | inker = Bryant, Rick | story = Pieces | title = The World of Krypton | volume = 2 | issue = #4 | date = March 1988 | publisher = DC Comics | location = New York}}</ref> Just as the planet began to shake apart and massive, exploding streams of green energy erupted through the surface of Krypton, Jor-El launched the matrix towards Earth, where it would open and give birth to the infant upon landing (the Post-''Crisis'' Superman therefore was considered to be technically "born" on Earth). Jor-El was not only determined that his son would survive the death of his birthworld, but that he would grow up on a world that vibrantly embraced living, as his forebears once did.
