In more modern times, [[Pariah (character)|Pariah]] performed an experiment similar to the one Krona attempted long ago on a parallel Earth (this was changed later to an alternate world in the post-''Crisis'' single universe).{{Citation needed|date=March 2011}} This experiment resulted in the reawakening of both the Monitor and the Anti-Monitor and the destruction of Pariah's universe.{{Citation needed|date=March 2011}} The Anti-Monitor rebuilt his army, taking over Qward and using the Thunderers as his own private army, as well as creating the Shadow Demons from the elite of the Thunderers.{{Citation needed|date=March 2011}}

The Anti-Monitor then released a massive anti-matter wave, absorbing the energies of the destroyed positive matter universes to grow in strength, and employed the second [[Psycho-Pirate]], using his emotion control powers to terrorize the populations of the planets he sought to conquer and destroy.{{Citation needed|date=March 2011}} The Monitor, along with his aide [[Harbinger (DC Comics)|Harbinger]], gathered a group of heroes and villains from various alternate universes to combat the Anti-Monitor.<ref>''Crisis on Infinite Earths'' #1. DC Comics</ref> The Anti-Monitor controlled one of Harbinger's duplicates and apparently killed the Monitor, but the Monitor created a pocket universe to contain and protect the remaining universes.

After defeats by various heroes, including  [[Supergirl (Kara Zor-El)|Supergirl]] and the [[Flash (comics)|Flash]] ([[Barry Allen]]) sacrificing themselves to save [[Superman]],<ref name="Crisis on Infinite Earths #7">''Crisis on Infinite Earths'' #7. DC Comics</ref> and to destroy an anti-matter cannon<ref>''Crisis on Infinite Earths'' #8. DC Comics</ref> respectively, the Anti-Monitor absorbed the entirety of the anti-matter universe and traveled to the beginning of time, intending to stop the formation of the positive matter Multiverse and to create a Multiverse where anti-matter prevailed. When the heroes followed him there, he began to drain the power from most of them.{{Citation needed|date=March 2011}}

However, the actions of the [[Spectre (DC Comics character)|Spectre]], empowered by the sorcerers of the surviving Earths, brought the Anti-Monitor to a stalemate. The villains of said Earths, sent to stop Krona from viewing the origins of the universe, failed due to squabbling, allowing Krona to see the hands of the Anti-Monitor and the Spectre struggling for domination, which collapsed the current Multiverse.{{Citation needed|date=March 2011}}

From the ashes rose a new, singular universe.<ref>''JLA: Earth 2'' Graphic Novel (2000), by [[Grant Morrison]]. DC Comics</ref> While various persons adjusted to the newly singular Earth (including those whose worlds and histories had been destroyed with the loss of the Multiverse), the Anti-Monitor, enraged, drew this new Earth into the anti-matter universe, intending to destroy this last bastion of positive matter once and for all.<ref>''Crisis on Infinite Earths'' #11. DC Comics</ref> What followed was the Shadow Demon War, wherein many heroes and villains lost their lives against the Anti-Monitor's forces. Finally, the combined efforts of various superheroes and villains (most notably [[Doctor Light (Kimiyo Hoshi)|Doctor Light]]; the heroic Alexander Luthor, Jr. of [[Earth-Three]]; [[Darkseid]]; [[Superboy-Prime|Superboy]] of [[Earth Prime]]; and [[Superman (Earth-Two)|Kal-L]], the [[Superman]] of [[Earth-Two]]) weakened the Anti-Monitor enough for Kal-L to deliver the final blow, destroying the Anti-Monitor by punching him into a star. The star went nova and caused anti-matter waves to erupt, threatening to destroy the entire anti-matter universe. Kal-L and Superboy-Prime were willing to resign themselves to their final fates, when Luthor revealed that he had created a "paradise dimension", and he used it to prevent the [[Lois Lane#Golden Age|Lois Lane Kent]] of Earth-Two from being erased from existence when the Post-''Crisis'' universe was formed, as he foresaw how events would unfold and refused to allow Superman to have to deal with such a terrible loss. Using his body as a portal, Alexander Luthor, Kal-L, and Superboy-Prime went into the "paradise dimension" alongside Lois.<ref>''Crisis on Infinite Earths'' #12. DC Comics</ref>
