Although the combined forces of the League and the Squad are able to defeat Lord's allies, they are unable to prevent Lord from achieving his goal; with the aid of a controlled Killer Frost, Lord acquires the Heart of Darkness from a vault, using it to enhance his powers to "infect" (take control of) the League. Lord uses the infected Justice League (apart from Batman, who Lord did not infect) to achieve "peace" across America, and has Waller kidnapped and taken before him. However, despite believing that he had taken precautions to control the Heart, Lord is forced by Waller to recognize that it is manipulating his perceptions, using Lord's powers to spread chaos and evil across the world, and twisting Lord's perception of what is transpiring. When Waller is able to bring him to his senses, Lord tries to remove the Heart of Darkness, but it consumes him and transforms him into Eclipso. Eclipso is driven out of Lord when Killer Frost is able to use her powers to create a prism of ice, channeling Superman's heat vision at just the right frequency to disrupt Lord's hold on his slaves, with Lord subsequently being immobilized by Killer Frost. Lord awakens in a cell specially designed to hold him, with injectors pumping so much blood thinner into him that he would bleed to death if he attempted to access his powers. He mockingly asks Waller if she set this whole thing up just to 'justify' the Squad to the League, but Waller declines to reply, and simply informs him that he is to prepare himself for service on "Task Force XI".
