During one of the Centurion's most grandiose schemes, he used a device called an Erasure Weapon, which was capable of erasing a being from history. After erasing several notable heroes from existence, Moon Maiden, along with the remaining members of the Justice League, the Teen Titans, and Infinity Inc. took the battle to the Centurion, in what was known as 'The Century War'. In an act of self-sacrifice, Moon Maiden, took herself and the Centurion high into the sky, and there destroyed his weapon, causing a great explosion, and removing the two of them from history. Only Hugh Klein was able to recall his daughter and the events that had occurred.
