It's a prequel that explores the origin story of the iconic characters, focusing on the relationship between Optimus Prime (originally known as Orion Pax) and Megatron before they became enemies. The movie will delve into the history of Cybertron, the home planet of the Transformers, and the events that led to the great civil war between the Autobots and Decepticons.

The film features a star-studded voice cast, with Chris Hemsworth voicing a younger Optimus Prime, and Brian Tyree Henry as Megatron.
