A universe, also known as a Zone, is an area in which life exists. Different universes possess different features unique to them. All universes coexist in the multiverse.


An individual universe is, when alone, shaped like a giant sphere, in a similar fashion to a satellite or star. Inside the universe is the region of space that consists of the many galaxies and nebulae that inhabit that universe. No two universes are alike.

All universes are connected in the multiverse in a similar fashion as a giant honeycomb. There is no open space in the multiverse.

Universes that possess the required technology can perform interuniversal travel, in which they open a portal that leads to a different universe. The multiversal government and Zone Jail, which are located in the largest universe, require that all universes capable of this travel adopt a currency known as the Orbit, for mutiversal trade.

The Sonic the Hedgehog, Archie Sonic the Hedgehog and Pokémon universes are three of the many universes that are defined as "Prime Universes", which are set as the bases for alternate universes.
