The Parasite was a dangerous supervillain that Superman and his generation of superheroes had once contended with, but at the time when Magog and his Justice Batallion hunted down supervillains and permanently defeated them, the criminal was nearly on the ropes when they found him. The Parasite pleaded for mercy, but his pleas went ignored, so instead he attacked by grabbing and ripping apart Captain Atom, which unleashed a massive amount of quantum energy that took out most of the team except for Magog and devastated the entire region of Kansas with the exception of Keystone City, leaving it a barren wasteland and throwing the entire United States into economic chaos due to the devastation destroying acres of agriculture used in food production.
