Before the Great War, Optimus Prime was known as Orion Pax; a young data clerk who worked in Iacon under the wing of Alpha Trion.

Alpha Trion was a mentor to Orion and believed that he was to become the next Prime.

However, great challenges laid ahead. A new threat in the form of Orion's best friend has arisen to stand against him. Megatron will stop at nothing to prevent Orion from claiming the Matrix, wishing to seize the power of the Primes himself.

With the fate of Iacon and many more colonies at stake, Orion Pax must step outside his comfort zone and rise to the challenge. The young data clerk had a treacherous journey ahead of him, but he remained determined.

Everyone was counting on him.

He had to succeed.

This journey would change him in more ways than one, shaping him into the Prime he was meant to be all along.

This is the story of how Optimus Prime, the last Prime, came to be.
