Transformers One

Paramount Animation and Hasbro present, in association with New Republic Pictures: the first animated "Transformers" feature – a work-in-progress version – since the 1986 original. This movie takes place entirely on Cybertron and follows the origin story of how Optimus Prime and Megatron go from being brothers in arms to sworn enemies, ultimately leading to the centuries-long war between the Autobots and Decepticons.
