|Appeared in||Justice League Unlimited: CADMUS Crisis|
|Actor||C. C. H. Pounder|
Amanda Waller is the director of Cadmus and is distrustful of the Justice League.
When The Question discovered Cadmus and was captured, Waller and Lex Luthor gave orders to Dr. Moon to run a full interrogation on The Question. When she believed, falsely, that the League had obliterated Cadmus headquarters, Waller decided to take action. She deployed dozens of Ultimen clones, led by Galatea to attack the Watchtower, intending to overload the reactor and destroy the League and their base. However, Batman convinced her to investigate Lex Luthor's role in the base's destruction, and Waller quickly found evidence of Luthor stealing a massive amount of Cadmus technology for his own use. She attempted to call off the attack, but Galatea refused to stand down.
In response, Waller released the senior Leaguers, who had turned themselves in as an act of good faith. With the Leaguers in tow, she personally went to arrest Luthor, stopping his attempt to transfer his consciousness into a potentially invincible copy of Amazo. At that point, Brainiac revealed himself (in Luthor) to Waller and the Justice League, and she took part in the battle against the two of them. Unknown to the League during this battle, Waller had ordered a massive airstrike on standby to kill the combined villains, the Leaguers, and even herself should the heroes have failed to stop the menace. Since the League was able to defeat the Lex/Brainiac fusion, however, this was averted.
