During ''Crisis on Infinite Earths'', it was revealed how the existence of all [[Parallel universes in fiction|parallel universes]] in the [[Multiverse (DC Comics)|Multiverse]] came to be, including the positive matter multiverse and also the anti-matter universe, and how the [[Monitor (Mar Novu)|Monitor]] and the Anti-Monitor came into existence; when the menace posed by the Anti-Monitor became apparent, several villains were sent back in time to stop him, but were defeated by [[Krona (comics)|Krona]] and the other Oans.{{Citation needed|date=March 2011}} In a [[Ganthet|final revision]], it was established that it increased [[entropy]] in the universe, shortening its existence by a billion years (see [[heat death of the universe|heat death]]).<ref>''Green Lantern'' version 4. DC Comics</ref> In any event, two beings were created, one on the moon of [[Oa (comics)|Oa]] and the other on the moon of Qward. On Oa, the being known as the Monitor was instantly aware of his counterpart, the Anti-Monitor (although his official name is the Monitor in his own universe, and he is often addressed as such, the name Anti-Monitor is used to distinguish him from his heroic positive matter counterpart). By this time the Anti-Monitor had quickly conquered Qward, as well as the rest of the anti-matter universe.{{Citation needed|date=March 2011}} In searching for other places to conquer, he also became aware of his counterpart. The two battled for a million years before eventually defeating each other, becoming inert for nine billion years.{{Citation needed|date=March 2011}}

In ''Final Crisis'', it was revealed that the Monitor was originally a probe created by the Overmonitor to learn more about the multiverse. However, being unprepared to deal with the complexity of life and the passing of time, the probe-Monitor was split into two symmetrical, opposite beings: the Monitor, embodying the positive matter and goodness, and the Anti-Monitor, embodying anti-matter and evil.<ref>''Final Crisis: Superman Beyond'' #2.
