Bringer Unicron. When tragedy at last ended the era of the Primes and brought forth the new race of lesser descendant Transformers he alone chose to be reborn in the Well of All Sparks as one of them, that he might know them and their needs more completely. All memory of his past life gone, he took the name "Orion Pax" and sought his way like any other robot on the new world becoming Optimus Prime once more when receiving the Matrix of Leadership when Cybertron faced a new enemy in his former friend, Megatron and his army of followers, the Decepticons. This brings a Great War to their planet of Cybertron. Optimus's origins and personality can vary depending on which "universe" he's seen in.

If the combat deck or Roller were to be destroyed, Prime could survive. However, despite the slight degree of autonomy they possess, the combat deck and Roller would not be able to survive without Optimus.

All three components can function independently, but injury to one is felt by the other two. However, in by far the most of the fiction, the humanoid
