Fictional character biography
In the distant past, a dying alien race created a number of devices to preserve their culture and sent them into space where they would encounter other civilizations and link their colonies. When a small group of these aliens arrived on the planet Krypton, a militaristic faction, led by Kem-L, killed them and corrupted one of their devices to preserve his ideal of Kryptonian culture; this device would eradicate alien influences, and hence Kem-L called it the "Eradicator."
One of the surviving aliens, the Cleric, took the Eradicator and a group of followers and left Krypton. Unfortunately, his followers died shortly after leaving.
Professor Emil Hamilton, who had previously examined the Eradicator, restored Superman's memory, and Superman then went into the Phantom Zone to stop the device. He encountered a projection of Kem-L and learned that only the House of El can control the Eradicator, but he first had to undergo a rite of passage. When Superman completed it, he commanded the Eradicator to shut down, and it complied.
