The reformed Black Adam is still vulnerable to his murderous host's influence, and he attacks the Justice Society of America under Theo Adam's control in "JSA" #6 (1999). In subsequent issues, Adam joins supervillain Johnny Sorrow's Injustice Society after Sorrow removes a malignant tumor from Adam's brain. He is sent to battle Wildcat, and easily defeats him, showing how easily he could kill him by taking him about 25,000 feet above the ground—just high enough for them to talk while unable to go any higher without the human Wildcat freezing or suffocating—explaining the different ways he could kill him, and asking what he will give for his life.
