Mobius is the main setting of the Sonic the Hedgehog television series. It is a planet inhabited by various sentient anthropomorphic animals, and other creatures with different societies. The planet consists mostly of unspoiled nature which its inhabitant live in harmony with. In the aftermath of the Great War, Dr. Robotnik overthrew the royal family of Mobotropolis, and began his campaign to replace all life on Mobius with robots via roboticization. The Freedom Fighters were soon after formed to end Robotnik's tyranny.
