Cybertron

Cybertron (サイバトロン, Saibatoron) is the home planet of all Cybertronians, both Autobots and Decepticons alike. It is also the source of Energon. Cybertron is (almost always) a shining metal, technological world; a planet of towering future cities without end and vast metallic plains, spiraling metal mountains and bottomless neon-lit chasms. Battling over the planet's resources, the AllSpark, and control of Cybertron is frequently the motivation for, or origin of, the Transformers' aincent, historical, but epic war, the Great War have started.

Synopsis
Eventually, the Decepticons started an uprising and fought the Autobots once more in an attempt to return to Cybertron.

According to Sentinel Prime, it doesn't rain liquid on Cybertron.

The Decepticons never made it, as Megatron called off the attacks to wait for him. As Megatron himself was captured, the future of the Decepticons was uncertain.

After Megatron's defeat, a group of Decepticons attempted to free him by disguising themselves as Autobot performers. However, they were discovered by Sideswipe and Cheetor, who imprisoned them in the Kaon Prison Complex with their leader. Following this defeat, a group of Decepticons launched an assault on the Energon Farms with a super-weapon of their own, Trypticon...
