Johns’ making the Anti-Monitor a scientist from the anti-matter universe contradicts the original origin. Unless his life was a cosmic event put into play by the universe itself to counter the creation of the Monitors in the positive matter universe. Kinda like how the Force will always try to balance itself in the Star Wars universe. So the Anti-Monitor rising from the primordial matter was just a simplification of Mobius’ life.
