Cybertron

Cybertron (サイバトロン, Saibatoron) is the home planet of the Transformers. 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 control of Cybertron and its resources is frequently the motivation for, or origin of, the Transformers' epic wars. Beyond these facts much about Cybertron can differ between continuities, see individual entries below.

Sometimes it is known as the body of their creator, Primus.
