Cybertron is a completely mechanized planet and is the homeworld of the Transformers. The world is made up of gleaming towers of machinery standing atop metallic plains. Even the deepest underground levels of the planet are entirely mechanical, with no organic life anywhere. The history of Cybertron differs between each Transformers continuity, but the one constant throughout each of them is that the planet is devastated by centuries upon centuries of war between its two main civilisations: the Autobots and the Decepticons.
