Antimatter Universe

The Antimatter Universe, also called the Netherverse and the Anti-Universe, is the home universe of the Anti-Monitor.

Original Timeline
At the dawn of time, Mar Novu time traveled to this location and by doing so revealed the existence of the positive matter universe to his antimatter doppelgänger, Mobius.

In 2018, The Flash was transported to this universe and was eventually captured by Mobius in order to power his Antimatter Cannon.

Current Timeline
Due to the Paragons' intervention Mar Novu did not arrive but a doppelgänger of his did and as such Mobius was still there to face the heroes. A battle ensued between the Paragons and his army of Shadow Demons, while Anti-Monitor fought The Spectre but they were eventually defeated causing the recreation of the Multiverse.
