Transformers is a media franchise produced by American toy company Hasbro and Japanese toy company Takara Tomy. It primarily follows the heroic Autobots and the villainous Decepticons, two alien robot factions at war that can transform into other forms, such as vehicles and animals.

The primary concept of Generation One is that the heroic Optimus Prime, the villainous Megatron, and their finest soldiers crash-land on prehistoric Earth in the Ark and the Nemesis before awakening in 1985, Cybertron hurtling through the Neutral zone as an effect of the war.
