In the TV series, Cybertron is a small planet once used by the
Quintessons as a factory to create assembly lines of soldiers and workers. Following a rebellion, the workers became the
Autobots and the soldiers became the
Decepticons. During
Optimus Prime and
Megatron's four million year absence,
Shockwave keeps the planet in stalemate until Megatron awakes in 1984, and he conquers the planet by 2005.
Cybertron is seen to have at least three moons, two of which are consumed by
Unicron in 2005. Unicron's head became an artificial satellite when his body was destroyed during his attack on Cybertron.

Cybertron is the material body of Primus, who was the good counterpart to Unicron. Primus enabled the Transformers to reproduce via budding of atoms but, when it spawned a dark energy, Primus wiped their memories of it. During Optimus Prime and Megatron's four million year absence, a guerrilla war was fought between
Emirate Xaaron and
Lord Straxus until the leaders returned in 1984. Interference from
Shockwave,
Starscream,
Galvatron and
Bludgeon kept the war going until the Autobots and Decepticons temporarily united in order to defend the planet from Unicron, and later joined forces in order to begin a new war against
Jhiaxus.

Using the TV series and Marvel comics as a backstory, Cybertron is a peaceful planet, formerly made of organic matter before Primus made it his vessel, inhabited by the
Maximals and
Predacons. The
Tripredacus Council bides its time waiting for war, but a new
Megatron is impatient and travels back in time to change history. Failing, he returns with a new virus giving him control of Sparks, before
Optimus Primal overthrows his rule, turning the planet into a techno-organic one.
Dreamwave

As in the Marvel comics, Cybertron is the material body of
Primus. The scars of battle with
Unicron at the dawn of the universe also influence the
Decepticons. During Optimus Prime and Megatron's absence, Shockwave kept the planet in stasis, and sabotaged their attempt in the 1990s to get back to Cybertron.
Unicron Trilogy (Armada, Energon and Cybertron)

Cybertron, Primus' material body, is inhabited by
Mini-Cons as well as Autobots and Decepticons, who are unaware they are weapons forged by
Unicron. The war is started by Megatron's attempt to gather them. Ten years of peace follow Armada (2002) and then Energon (2012). After Cybertron's climax, the planet has an atmosphere suitable for humans and wildlife.
Transformers: The 2007 Live Action Film
Cybertron in the
2007 film
Cybertron is not shown as a metallic sphere, but a mountainous husk of a planet that has been ravaged by war. According to
Transformers: The Movie Prequel comic book by
IDW Publishing,
Optimus Prime and
Megatron co-ruled Cybertron. The
Allspark is responsible for giving life to the Transformers. When Megatron begins a war to control it for himself, Optimus sends it into the depths of outer space in the hope that he can defeat him quickly. The war drags on, and Optimus sends
Bumblebee to retrieve it, because its absence will cause the planet to shut down.
