In all ''Transformers'' stories, the Autobots and their adversaries, the [[Decepticon]]s, originated on the [[planet]] Cybertron. The planet is almost always depicted as a metallic sphere covered in multi-level cities and structures.<ref>Marvel US issue #1, page 1, panel 2: "No rock or soil or sand contributed to its bizarre geography." "Its content was entirely mechanical."</ref> The capital of Cybertron is Iacon.<ref name=":6" /> Although there is no animal or plant life on Cybertron, animated cartoons have depicted it as having an atmosphere that human visitors can breathe,<ref name=":6" /> and some stories have shown the planet to experience weather, such as rainfall and storms.<ref name=":4" /><ref>Marvel US issue #76, page 9-19</ref>

Starting with the original series ''The Transformers'', Cybertron is shown to house a seemingly living super-computer called Vector Sigma.<ref name=":6" /> At first, Vector Sigma is depicted to be the source of life for new transformers, imbuing the robots with life and personality.<ref name=":6" /> Later, media consistently portrays that Vector Sigma harnesses the power of another source known as the Allspark to imbue a transformer with its individual soul or "spark."<ref name=":1" /> Different versions of Transformers media have also shown the life-giving energy of the Allspark to be an ancient artifact (either called the Allspark or the Cube) or have shown it to be a pool of positronic energy located on Cybertron known as the Well of AllSpark or Well of AllSparks.<ref name=":4" />

The UK comic books written by Simon Furman established that Cybertron was once a god-like being named Primus.<ref name=":1" /> Following a battle with another god-like being known as [[Unicron]], Primus transforms into Cybertron, a planet of "living metal", and eventually uses his energies to grant life to living robots. In some stories, Primus does this in the hopes that these robots will become warriors who will defeat Unicron and similar threats.<ref name=":1" /> Following the introduction of Primus, it is said in some media that it is his mind that acts as the will of the super-computer Vector Sigma. Various stories depict the first living creations of Primus to be a group known as the "original thirteen Primes" or simply "the Thirteen." Eventually, each of the thirteen Primes grants a copy of their nature and schematics into the Allspark energy source that will imbue later Cybertronians with life, making all later transformers their "descendants" who each inherit a unique combination of traits from at least some of the original Thirteen.<ref name=":4" /><ref name=":3" />

Although the transformer race originated on Cybertron, different groups of Cybertronians later left the planet and colonized other worlds. This has led to different factions of transformers with their own cultures and beliefs, some of whom become Autobots while others have no desire to involve themselves in Cybertron's civil war.<ref name=":1" /><ref name=":4" /><ref name=":5" />
