The dawn of time

The Thirteenth Legion of Autobots had already established a thriving civilization on Antilla. Cosmic Rust

(Don't ask us, we just archive this stuff.)

Millions of years ago

"Near the beginning of the universe," an entity known as Primacron comes into existence and begins to create. Among the beings to which he gives life are the first mechanoids known as "Primitives," one of which he takes as his assistant in his continuing experiments. His creations steadily grow bigger and more complex until eventually, he creates the planet-sized transforming robot called Unicron.

Primacron intends for Unicron to consume all life in the universe, leaving it a blank slate for him to do with as he wishes, but Unicron rebels. Seriously injuring Primacron, Unicron sets out into the universe on his own, and Primacron's assistant escapes to a world near the centre of the galaxy. Call of the Primitives

Before Cybertron was, Vector Sigma was. The Key to Vector Sigma, Part 1

12 million years ago

The alien Quintessons establish themselves on the metallic planet of Cybertron. The planet's precise origins are never divulged, but it is known to have rocky sub-levels, Desertion of the Dinobots, Part 2 The Dweller in the Depths indicating an organic beginning. However, whether or not the Quintessons colonised an existing metal world or terraformed an organic one is never revealed.

Seeking to create a race of slaves to serve them, the Quintessons use their technology to create bio-mechanical beasts known as Trans-Organics. The designs are a failure, and it is decided to mass-produce robots for slaves instead. The Dweller in the Depths Forging their bodies in the fires of the Plasma Energy Chamber The Rebirth, Part 1 and imbuing them with intelligence using the mega-computer Vector Sigma, The Key to Vector Sigma, Part 1 the Quintessons create two classes of robot: consumer goods and military hardware. With these robot creations performing all their labour for them, Quintesson culture grows progressively more decadent. Violent gladiatorial matches are even staged amongst the robots, with the losers smelted and their raw materials used to create new robots. Five Faces of Darkness, Part 4

At some point during this period, the consumer goods robots come into possession of the mysterious Matrix of Leadership. The origins of this talisman are unknown (there is some suggestion it may be connected to Primacron's assistant), but it was passed from robot to robot through the years. Known holders during this time include Primon, Prima and Prime Nova. Five Faces of Darkness, Part 4

Eventually, the consumer goods robots develop true sentience and rise up in rebellion against their Quintesson creators. This is the beginning of the First Cybertronian War. Five Faces of Darkness, Part 4

11 million years ago

A rebel cell of consumer goods robots led by A-3, including Beta, turn the Quintesson slave brand into a symbol of freedom when they assault the Quintessons' Hive City. Although they meet resistance in the form of the Quintessons' gigantic Dark Guardian robots, A-3 activates the Coder Remote device he has placed within his slave brand, deactivating the Dark Guardians and allowing the robots to take the city.Forever Is a Long Time Coming From this victory, the Quintesson line of dominoes begin to fall, until the aliens are eventually defeated, and forced to flee the planet. Five Faces of Darkness, Part 4

Peace settles on Cybertron for a time, with the robots building their own society, during which time, the Matrix is held by Guardian Prime. Five Faces of Darkness, Part 4

9 million years ago

The violent military hardware robots, now known as the Decepticons, seek conquest and begin the Second Cybertronian War when they turn their aggression against the consumer goods, now called the Autobots, at the time led by Zeta Prime. A series of conflicts ensue, with both sides claiming victory at different points in time. Desertion of the Dinobots, Part 2 Ultimately, never having been designed for combat, the Autobots realise the futility of attempting to match the Decepticons' strength and firepower, and, under the leadership of Sentinel Prime, they instead turn to stealth, reconstructing their bodies so that they can transform into vehicles and machinery. With this new skill, the Autobots are ultimately able to win the war, and they rule the planet for many centuries. Five Faces of Darkness, Part 4 With the peace policed by the Guardian Robots, reprogrammed version of the Quintesson's Dark Guardians, energy becomes plentiful and the planet shines with a healthy golden glow, denoting this period as the Golden Age of Cybertron. War Dawn

Eventually, however, the Decepticons also develop transformation, and they couple the technology with robot mode flight powers to renew their aims for conquest. Thus it is that Megatron is born. Five Faces of Darkness, Part 4

Assembling a small group of like-minded individuals, including Shockwave and Soundwave, War Dawn and increasing his ranks by using his Robo-Smasher to reprogram Autobots, The Secret of Omega Supreme Megatron stages an attack on the outer cities War Dawn and kills Sentinel Prime, who entrusts the Matrix to the aged A-3, now known as Alpha Trion. Five Faces of Darkness, Part 4

For whatever reason, Megatron's actions are not made full public knowledge, and the Decepticons' impressive flight powers make them objects of hero worship for the young Autobot dock worker, Orion Pax. However, Orion learns the folly of his ways when he is attacked by Megatron as part of an evil plan by the Decepticon to steal the energy in Orion's warehouses. Both Orion and his girlfriend Ariel are fatally wounded by Megatron, but are rescued by the time-displaced Aerialbots and brought to Alpha Trion. The pair are the first subjects for Alpha Trion's new method of reconstructing Autobots into truly battle-hardy configuration, becoming Optimus Prime and Elita One. Given the Matrix by Alpha Trion, Optimus became Autobot leader for the newly-begun Third Cybertronian War. War Dawn

Around this time, "shortly before" the war truly reignites, the scientists Starscream and Skyfire depart Cybertron to explore the prehistoric planet Earth. Skyfire is swept up in a polar windstorm and separated from Starscream. After failing to locate his friend, Starscream returns to Cybertron, eventually abandoning his scientific pursuits, enrolling in the Cybertron War Academy and joining Megatron's Decepticons. Fire in the Sky

4 million years ago

After five million years of war, Cybertron's energy is drastically drained, necessitating an Autobot expedition to alien planets in search of new source of power. Optimus Prime and his best and brightest board a mighty spacecraft, but their plan is discovered by Megatron. A Decepticon assault on the Ark's launch bay leaves Prime and his crew believing Elita One and her team have been destroyed. The Search for Alpha Trion The Autobots proceed to blast off, but they are followed and ambushed by the Decepticons aboard their own space cruiser. The ships are caught in the gravity of the nearby planet Earth and crash so violently that all the Transformers are knocked offline.More than Meets the Eye, Part 1

A trio of Decepticons bail out of the Decepticon space cruiser in an escape pod before it crashes, and they spend the next four million years quietly active in the Demon Swamp, adopting insectoid alternate forms that will eventually lead to their being dubbed "Insecticons".A Plague of Insecticons

A final act of sabotage by Autobot Mirage brings the Decepticons' cruiser crashing back to Earth, where it lands in the ocean. More than Meets the Eye, Part 3

Although the Autobots intended to return to Cybertron, the revelation that the Decepticons have survived the crash forces them to stay and defend the planet. The Decepticons develop an intergalactic space bridge transportation system to send energy back to Cybertron, Transport to Oblivion while the Autobots expand their ranks with the addition of the powerful Dinobots. S.O.S. Dinobots War of the Dinobots The Decepticons unearth the frozen form of Skyfire, but he turns against his old friend Starscream and sides with the Autobots, helping to foil the Decepticons' plans to harness the power of the Earth's core.

The Decepticons ally themselves with the human scientist Doctor Arkeville, using his mind-controlling hypno-chips to amass an army of human slaves. The Ultimate Doom, Part 1 Simultaneously, the villains construct a huge space bridge to transport Cybertron itself into Earth's orbit, causing massive worldwide chaos, and put the human slaves to work gathering energy. The Ultimate Doom, Part 2 At the eleventh hour, the Autobots are able to break the Decepticons' mind control and blast Cybertron out of Earth's orbit. The Ultimate Doom, Part 3

The planet is in danger of being torn apart until the Autobots return the island's energy. Dinobot Island, Part 2

When the Decepticons create fake evidence so as to trick the humans into thinking that the Autobots are evil and the Decepticons are good, the Autobots are exiled from Earth. Megatron's Master Plan, Part 1 Of course, as soon as the Autobots are gone, the Decepticons reveal their true colors and take over, at least until the Autobots return to Earth and defeated them. Megatron's Master Plan, Part 2

After a space bridge accident, Optimus Prime, Bumblebee, Smokescreen, Inferno, Perceptor, and several Decepticons, are transported to an alien planet where they are no bigger than toys. The Decepticons manage to escape back to Earth, but the Autobots have to return via a different means: a child's toy rocket that somehow can actually work. Child's Play

The five Autobots are captured by an alien gambler named Bosch, who paralyzes them, bar Smokescreen, and sells them to Lord Gyconi. Forced to find a way to rescue his friends, Smokescreen teams up with Bosch and a bounty hunter named Devcon to rescue the Autobots, who are forced to fight against giant, mutant animals. The Autobots later successfully manage to return to Earth. The Gambler

Megatron travels to the center of Cybertron and uses Vector Sigma to create the Stunticons. The Key to Vector Sigma, Part 1 Optimus Prime and Alpha Trion, who have followed Megatron, also use Vector Sigma to create the Aerialbots, albeit at the cost of Alpha Trion merging with the computer. The Key to Vector Sigma, Part 2

Sometime afterwards Starscream goes rogue on the Decepticons, travels to Cybertron, breaks into the Decepticon Detention Center, and releases the Combaticons as his own personal army.

Starscream's Brigade The Combaticons and Starscream promptly ditch each other and go their separate ways. The Combaticons decide to take over Cybertron, and actually win, successfully booting Shockwave out into space. Shockwave bumps into Starscream, and this is the beginning of a brief and unusual alliance that eventually escalates from Starscream and Shockwave to the Decepticons and Autobots as a whole, both sides recognizing the threat of the Combaticons. After the Combaticons are defeated, the alliance ends, and Megatron secretly has Bruticus reprogrammed to be loyal to him. Starscream is also allowed to rejoin the Decepticons.
