Everything inside and outside of existence.
The omniverse is the unfathomable everything inside, as well as outside existence from all the atoms to beyond the edge of space, all dimensions/alternate realities and the sum of all the verses combined (the microverse, universe, multiverse, megaverse, metaverse, etc.).

(Note: The omniverse isn't to be confused with the universe. Please see my definition of the universe for more information).
