Decepticon - Transformers: Generation 1

Transformers: Generation 1

The evil Decepticons are from a race called Transformers - robots that can change into vehicles, mechanical devices and even animal forms. They waged war for eons on their home planet of Cybertron against the heroic Autobots. Both factions needed supplies, and select numbers from each side intended to get them. The Autobots weren't looking for a fight with the Decepticons, but they get one out in space anyway. When the Decepticons board the Autobots' ship it takes a beating and crashes onto Primitive Earth and knocks everyone unconscious. Millions of years later, in 1984 a volcano eruption causes a probe to give them all new forms which come from vehicles in the surrounding area. After the featured film The Transformers: The Movie, Megatron was reformed as Galvatron, and Optimus Prime was replaced for a time by Rodimus Prime, only to return later on.
