The Sonic the Hedgehog universe is a prime universe that resides somewhere in the omniverse. It contains many elements from the franchise of the same name, along with some modified and brand new elements.



The Sonic the Hedgehog universe was formed trilions of years ago along with the rest of the omniverse as one of the prime universes. It was formed as a result of the large amount of empty space that resulted from the omniverse's initial creation.

Over time, many galaxies formed in the universe, and new universes were formed in the omniverse using this prime universe as a template. Eventually, the Earth was formed, kicking off all of the important events in this universe.
