Antimatter Universe

The Antimatter Universe is the home universe of Mobius.

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 doppelgänger Mobius.

In 2018, Barry Allen was transported to this universe and was eventually captured by Mobius in order to power up his antimatter cannon.

Current timeline
Due to the action of the heroes of the original timeline, the heroes prevented the arrival of Mar Novu but since another doppelgänger of Mar Novu did arrive, Mobius was still there to face the heroes. A battle happened with his army of shadow demons against the heroes, and Mobius fought the Spectre but was eventually defeated causing the recreation of the Multiverse.
