Three years after the events of The Last Knight, while the Autobots are restoring Cybertron and the Decepticons are conspiring to the shadows, the humans of Earth remain a distant term with the Transformers. All is well, until Quintessa awakens Unicron in the depths of Earth. As Unicron is the Earth itself, the planet (and eventually the universe) is in the wake of an apocalypse. Optimus Prime and the Autobots must gather forces of old and current allies, as they are going to face their greatest enemy in their most darkest hour.
This Transformers story serves as what could have been the final chapter of Michael Bay's Transformers saga.
