Perhaps the most notable impact the Anti-Monitor had on the Post-Crisis universe was the elimination of the Multiverse aspect of the DC Universe. Previously, there existed an infinite number of Earths, each one with a unique history, that could be accessed through various means, the most common being vibrational attunement. During Post-Crisis, with the restart of the universe as one thanks to the machinations of the Anti-Monitor, a simpler, more streamlined DC Universe seemed imminent, with characters acquired from Charlton Comics, Fawcett Comics, and Quality Comics all becoming incorporated into the new DC Universe.

During the war between the Sinestro Corps and the Green Lantern Corps, the Anti-Monitor contacted Cyborg Superman to inquire about the status of New Warworld. The cosmic tyrant stated that he would soon abandon Qward and that he would kill Henshaw for his services, allowing him the peace that had for so long evaded the Cyborg. When the Lost Lanterns made their way to the anti-matter universe to save Hal Jordan and the Ion power, they inadvertently stumbled upon the Anti-Monitor in a basement chamber of his stronghold on Qward. He was seemingly experimenting on or torturing the Ion entity previously inhabiting Kyle Rayner. He proceeded to kill Ke'Haan before the other Lanterns forced him back, taking the Ion entity from the
