Billion Years Ago 1- In this Universe, The One (or God) created Unicron to explore the universe, but instead destroying it on his path, so The One split Unicron in two creating another higher being known as Primus, they became a Multiversal Singularities, Unicron exist in one universe at the time, while Primus existed in all universes at once
Billion Years Ago 2- The two Gods fought each other, Primus trapping Unicron in Planetary Jupiter sized Asteroids, Primus is trap inside the planet full of organic life, but ended the life on this world, His core became Vector Sigma and the Planet was reformed with his nanometal (or his blood-cell) turning the Organic Planet into metal planet known as Cybertron. The Planetary Asteroid which Unicron is trapped was experimented by an Alien Scientist Primacron, who unknowingly gave Unicron his transforming body he needed to consume the universe. Unicron began to consume 20 planets and it's species on it
20 Million Years Ago 1- Primus created life from his own essence and birth the first 13 original Transformers:
-Prima: The leader of the Thirteen, a warrior of light and the first Matrix-bearer who wielded the Star Saber.
-Vector Prime: The master of time and space, which he could manipulate through his Blades of Time.
-Logos Prime: An enigmatic figure sought to pass on his incredible powers over time and space to an heir.
-Solus Prime: The master artificer and creator of many of the Primes' weapons through use of her incredible Forge. She was the first female Cybertronian.
-Micronus Prime: The conscience of the Thirteen, and the first Mini-Con, able to link up with and enhance the power of his siblings through the use of his Chimera Stone; responsible for creating the alternate dimension of Microspace.
-Alchemist Prime: Student of the elemental structure of the natural world, aided in this by his Lenses, which allowed him to see further and deeper than anyone, in both material and spiritual senses; fond of the occasional tipple, with some claiming that he still walks Cybertron in the form of a humble bartender.
-Nexus Prime: The first and greatest combiner, granted the ability to divide himself into separate forms by his Enigma of Combination. Unpredictable, fascinated by change, and a lighthearted prankster.
-Onyx Prime: The first beast-form Cybertronian, a primitive and spiritual being able to view other times, places, souls, and even the afterlife through his three-faced Triptych Mask.
-Amalgamous Prime: The joker of the Thirteen and the first Shifter, unpredictable and easygoing. He was first Cybertronian with the ability of transformation, granted him by his Transformation cog, which became the basis for the cogs in all subsequent Transformer life.
-Quintus Prime: A daydreamer and perfectionist whose drive to express his ideas led him to become a scientist. His artifact was the Emberstone, which gave him the ability to create life
-Liege Maximo: The "Prime of Lies", a black-hearted and amoral manipulator. Though his artifact was notionally the toxin-loaded Liegian Darts, his real skill was his ability to talk others into his way of thinking.
-Megatronus Prime: Now known as The Fallen, guardian of entropy and wielder of the Requiem Blaster, the Fallen's name was stricken from history when the dark warrior turned on his siblings
-The Thirteenth Prime: the last and most mysterious of the Thirteen, all we can say for certain is that he bore a strong connection to the Matrix of Leadership and his depictions look awfully familiar...
The Thirteen Prime we're Tasked to to battle Unicron and win. And the born of the first Cybertronian/Transformer (Cybetronus cybertronii)
20 Million Years Ago 2- After Unicron was defeated, he felt furious. So then he created an Alien lifeform in his own image known as The Quintessons with half mechanic and half organic parts (Their Organic parts are from the Alien Lifeforms that Unicron consume them along with it's planet BTW). The Quintessons we're tasked by their creator, Unicron, to define Primus and reported back to him. They began to Invade Cybertron and enslaving the Cybertronian species and the Original Thirteen, they started making experiments on Cybertron. They build a factories to mass-produce them the ancestors of the Autobots were designed as "consumer goods," and the Decepticons began as "military hardware", the Thirteen we're used as the templates for new bodies and given life through Vector Sigma. The product lines created a great profit to the Quintessons over the course of a million years The one of the Original Thirteen, The Thirteenth Prime breaks free from his prison, gather the Cybertronians to join him rebel against the Quintessons and exiled them, reclaiming Cybertron. The Matrix of Leadership is still a conduit to Primus and it still passed on to Autobot Leaders in the future of Cybertron while holding the wisdom to previous ones. The rest is history
