100,000 years later Kryptonian society was tipping toward decadence and eventually political strife resulted from the debate as to whether clones were sentient beings and should have rights (sparked by the presence of an alien missionary known as the Cleric, who carried "the Eradicator"). 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. 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.
