Mobius is a location that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is an alternate version of Mobius where Robotnik attempted to defeat the Freedom Fighters by turning them into cyborgs.
Dr. Robotnik decided to destroy the Knothole Freedom Fighters once and for all by turning them into cyborgs. The plan backfires, as the Freedom Fighters are now stronger than ever. The Cyborg Freedom Fighters march into Robotropolis to defeat Robotnik, for what they hope is the last time. Robotnik then roboticizes himself, becoming Robo-Robotnik. He destroys the Freedom Fighters, with Cyborg Sonic fleeing to the Cosmic Interstate to find new allies. With the help of numerous other Sonics, Cyborg Sonic defeats Robot-Robotnik in his attempt to take over the multiverse with the Giant Borg. He returned to his Zone with Robo-Robotnick's head.
