Mobius is the name given to the Alt-Earth Sonic and friends live in. Technically, Mobius is just a country on Alt-Earth, but since it takes up half the planet, it is simply referred to as Mobius.


Mobius is home to humans and anthropomorphic animals alike, with the latter being a bit more commonplace than the former. There are more kids than adults, but that's because the kids who grew into adults had kids themselves. Plants grow aplenty in Mobius, such as Mobisia Marvellosa Marigoldias and poison flowers.


The climate is what'd you expect of regular Earth. It snows in the winter, rains in the spring, etc.


The effects of a nuclear winter caused normal animals to gain human properties, and they were the pioneers of what'd become Mobius. The non-anthropomorphic animals became woodland creatures. In 1981, a newborn Sonic the Hedgehog moved to Station Square, a borough in Central City. He'd grow up to become the defender of Mobius.

Significant Populations

Sonic the Hedgehog, as noted before, lives on this planet. So do his friends Tails the Fox, Amy Rose, Johnny Lightfoot, and many more. Echidnas, rabbits, foxes, lizards, and humans live on Mobius, and even artificial intelligence like Eden live there.
