Judomaster was one of the members of the Justice Battalion team led by Magog, who sought to permanently defeat all known supervillains. She and several Justice Batallion members were in the process of apprehending the Parasite in Kansas. 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.
