Connections
Most Omiverse series are connected by the same species who live in the Omiverse (and probably not in other dimensions), which include Mordidans, Cervellons, Bionians, Lfs and many more.

Despite the randomness of some species, these species still exist on their planet in action series such as Ben 10: Ruins of Earth and Simien 10: Polyverse. Even as impossible as they can be. Eventually, the galaxy enters some sort of apocalypse thing where only the random species survive. where the very very very impossible events of The Random Alien Movie happen.

Other than similar species, the series are also connected slightly by plot, most notably Simien 10: Polyverse and the Omni-Knights (which will be revealed in an upcoming Polyverse episode). Also, many of the DNA donors for the Polytrix are characters from The Omni-Knights and Plumbers.

While Ben 10: Stupidity Force is not a part of this timeline, the species shown in BTSF still appear in the Omiverse. The events of BTSF happen in a dimension closely parraleling the Omiverse.

Simien 10 and Den -10 are not part of the Omiverse, but again, the species existing in them appear in the Omiverse. Den -10's main crew exist in the Omiverse timeline but will probably not make an appearance. Simien 10's crossover with the BTSF dimension is still canon to the BTSF timeline.

The Mega Omi Crossover is still canon to the Omiverse series such as The Omni-Knights and Plumbers. The upcoming Epic Omi Crossover will be more canon to all the series.
