Multiverse Unity: Invincible and Vox Machina

Multiverse Unity: Invincible and Vox Machina is an adult animated crossover TV movie, airing exclusively on Amazon Prime Video. It is part of the Multiverse Unity franchise, and is a crossover between the Amazon Studios' animated series Invincible and The Legend of Vox Machina.

Premise
A experiment by Rudy Connors / Robot is jeopardized by Nolan Grayson / Omni-Man during a fight against the Immortal, who is apparently killed in the progress. Meanwhile, Pike Trickfoot tries to banish the Chroma Conclave into other dimensions, but only Umbrasyl is engulfed. These acts (which happen in different places in the same time) eventually cause the Immortal and Umbrasyl to merge into one single entity of destruction called the "Eternal Devourer". The transformation also breaks the Multiverse open, and merges both dimensions with one another. Mark Grayson / Invincible must team up with Vox Machina to settle things right and defeat the Eternal Devourer, whose power is affecting villainous forces from both universes, including the Viltrumites and the Chroma Conclave.
