Most of what is known about Primus has been lost to time and what is known is believed to be mere speculation and some consider it religious nonsense. However, if the Cybertronian texts are to be believed, Primus and his kinsmen were sent to this universe after their creators were tired of their endless war with each other. While most of them made peace with each other, the final three combatants in the millennia long battle were three siblings: Primus, Gaea, and Unicron.

With Gaea and Primus fighting Unicron near endlessly, their opponent took advantage of this. Unicron, having stored an immense power inside him, attacked Gaea with a beam of pure energy so strong that it sent her spiraling through space, never to be seen by her brothers again. With Unicron's energy depleted, Primus, fueled by the hatred of what Unicron did to their sister, was able to kill Unicron. Sending his body adrift in space, Primus finally had a moment to think.

Feeling regret for all the lives that had been taken in his unneeded senseless war, Primus decided he would become a being of life. Using what power remained inside him, he transformed into the planet Cybertron and created the first of its life, the original Thirteen Primes.

From there on, Cybertron has been the home to billions of lives over the millennia of his rest. But deep down, in the very core of Cybertron, holds the spark of Primus. It is what fuels the planet and what gives life to all with a spark themselves. While many believe that Primus died giving life, in truth, he lives, and he fears that the foe he defeated long ago will return to kill him and all his children.
