In Final Crisis, it was revealed that, in the wake of the birth of the original Multiverse, an unfathomable being of limitless imagination, the original Monitor, or Overmonitor, became aware of the life germinating in the budding Multiverse, occupying the void space in which he resided and which he encompassed. Curious about it and wanting to interact with and know better the lesser life-forms birthed by the Multiverse, he fashioned a probe, a smaller Monitor. Unprepared to deal with the complexity of life and the passing of time, the probe-Monitor was instantly split into two symmetrical, opposite beings upon coming into contact with the Multiverse itself: the Monitor, embodying the positive matter and goodness, and the Anti-Monitor, embodying anti-matter and evil.[3]
