Some kaiju are said to live outside of the universes within the empty void. Though this isn't confirmed, it is speculated that the Void Gas (which comes from the void) is created by a creature that managed to adapt to live in the nothingness of the void. Sentient Void Liquid, expelled from the Void Gas, drifts around the Void and occasionally slips out into other universes. The being known as The Wormhole Maker was banished to this void long ago. The Universivore spawned in the void billions of years ago, where it roams around and eats universes. G-Rex, being a living universe, automatically exists within the void when he takes his true form.
