Editing Krypton (comics) (section)

====History====
The new Krypton was approximately one-and-a-half times larger than the Earth and orbited a red sun called Rao fifty [[light-years]] from the [[Solar System]]. Krypton's primordial era produced some of the most dangerous organisms in the universe. It was for this reason that 250,000 years ago, Krypton was chosen as the place to create [[Doomsday (comics)|Doomsday]] through forced evolution. Until its destruction, many dangerous animals, including ferrophage moles, still existed on Krypton. Kryptonians had to use their advanced technology to survive.

Over 200,000 years ago, Krypton had developed scientific advancements far beyond those of present-day Earth, and had discovered a way to conquer disease and aging by perfecting [[Clone (genetics)|cloning]]; vast banks of clones, kept in stasis, held multiple copies of each living Kryptonian so that replacement parts were always available in the event of injury. All Kryptonians were now effectively [[Immortality|immortal]], "with all the strength and vigor of youth maintained",<ref>{{Cite comic | writer = [[John Byrne (comics)|Byrne, John]] | penciller = [[Mike Mignola|Mignola, Mike]] | inker = Bryant, Rick | story = Pieces | title = The World of Krypton | volume = 2 | issue = #1 | date = December 1987 | publisher = DC Comics | location = New York | page = 15 | panel = 3}}</ref> and for millennia they enjoyed an idyllic, sensual existence in an [[Arcadia (utopia)|Arcadian]] paradise.<ref>{{Cite comic | writer = Byrne, John | penciller = Mignola, Mike | inker = Bryant, Rick | story = Pieces | title = The World of Krypton | volume = 2 | issue = #1 | date = December 1987 | publisher = DC Comics | location = New York}}</ref>

100,000 years later Kryptonian society was tipping toward decadence and eventually political strife resulted from the debate about the use of clones (three by each Kryptonian; one child, one teen and one adult, perfectly preserved in stasis in large clone banks) to repair any hurt and avoiding death, if they were sentient beings and should have rights to be awakened to live as any other Kryptonian, sparked in addition by the presence of an alien missionary known as [[the Cleric]], who carried "the Eradicator".<ref name="actionannual2"/> Eventually this disagreement led to open violent conflict. A woman named Nyra, seeking what she considered a suitable mate for her son, Kan-Z, had one of her younger clones removed from stasis. The clone gained full sentience and was presented to society as a normal woman. When Kan-Z discovered that his fiancée was in fact his mother's clone, he killed the clone, then publicly killed his mother and also attempted his own suicide before being stopped. Kan-Z also publicly broadcast the entirety of his discovered findings as to what his mother had done across the entire planet. This key incident ignited the Clone Wars which lasted for 1,000 years, during which Kryptonian science was turned to warfare and several superweapons were developed and used. Among them was the device known as the Destroyer.

Although the Eradicator's effects (altering the [[DNA]] of all Kryptonian lifeforms so that they would instantly die upon leaving the planet) were felt immediately, the Destroyer's effects were possibly more significant: by the time the Kryptonian government admitted defeat and abolished the clone banks, a pro-clone rights terrorist faction known as [[Black Zero (DC Comics)|Black Zero]] had started the Destroyer (activated by Kan-Z himself), a device which functioned as a giant atomic energy gun, projecting massive streams of nuclear energy into the core of Krypton, intended to trigger an explosive chain reaction within Krypton's core almost immediately.

The destruction (by Van-L, an ancestor of [[Jor-El]]) of the Destroyer eliminated the Post-''Crisis'' city of Kandor in a fiery nuclear explosion, but it was believed at the time that the device had been stopped before it could achieve planetary destruction. Centuries later, Jor-El himself would discover that the reaction had only been slowed to a nearly imperceptible rate and it would eventually destroy the planet as intended.
