Moebius

Anti-Mobius (also known as Moebius) is an alternate-universe zone and home of the Anti-Freedom Fighters, including the infamous Scourge the Hedgehog. Typically, people from the Anti-Mobius universe have opposite personality traits of their Mobius Prime counterparts.

The Great Peace and Decline
Roughly around the same time as the conflict in Mobius Prime's history known as the Great War, Anti-Mobius experienced a time of peace and prosperity known as the "Great Peace". Scourge's father Anti-Jules was a key member in bringing about the Great Peace. Scourge described it as an event that "brought everyone together in one big group hug." After ten years however, things on Anti-Mobius "stagnated" and the Great Peace broke down (this is around the same time as Dr. Ivo Robotnik's coup d'état). Thus an era of war and violence errupted.
