Omniverse

The multiverse in which Transformers inhabit sometimes interacts with the home multiverses of otherwise unaffiliated beings, such as the Avengers or the participants in the Star Wars. The collection of these multiverses could be deemed an omniverse, but there is no Transformers-based source for this.

However:

1. Primus wishes to join the Omniversal Matrix when he has completed his cosmic mission.
2. The Fallen has been classified as an "omniversal tyrant."

As the meaning of the word "omniversal" has not been defined for the Transformers universe, what these descriptors mean in terms of Primus and The Fallen falls into personal canon or fanon.
