League going rogue. Cadmus started as "Project: Achilles" and was designed to deal with Superman if he were to attack the Earth, much like how he was brainwashed by Darkseid into invading Earth at the end of Superman: The Animated Series. The project was created by Lex Luthor and his mutual ally General Nathan Hardcastle, who was later killed by Galatea on orders of Cadmus. The project's goals would eventually extend to the Justice League following the Justice Lords incident. Cadmus was later shown to be backed by Luthor himself, who only financed the project in a grab for superpowers of his own; a new AMAZO robot with Luthor's conscious mind implanted in it. After taking what he needed to build it from Cadmus and learning the League had figured out his link to the organization, Luthor attempted to destroy the organization by hacking into an immense laser built into the League's Watchtower. Although the building was destroyed, Amanda Waller had the facility evacuated after Superman and Huntress broke in to rescue The Question from Moon's captivity. It was then revealed that Brainiac was living inside Luthor at the time, improving upon his physical health and strength while tricking him into funding the project. After they were confronted by Batman, Waller, and later the rest of the founding members of the Justice League (which Waller had released from custody), Luthor and Brainiac escaped to a Cadmus building in Washington, D.C. in order to merge with the Dark Heart, a nanotechnology-like alien being which the League defeated thanks to Atom. After both of them were defeated, Cadmus ceased operations against the Justice League and the League itself announced the establishment of a planet-side base (modeled after the Hall of Justice) to improve their public relations. However, there were a few former members of Cadmus who were still against the Justice League. For example, Tala would join Gorilla Grodd's Secret Society whereas General Wade Eiling turned himself into "The General" by injecting himself with Captain Nazi's super-soldier serum. As shown in the episode "Epilogue", Cadmus is shown to be in operation years later, as elements of the organization were later brought together by Waller to initiate "Project Batman Beyond" to ensure that there "would always be a Batman" in some form or another as she came to respect the Dark Knight over time and was concerned with the possibility of his eventual
