Optimus Prime was Orion Pax, a naive and humble librarian. He was unsure of what to do with the corrupt in the government, but his boss, Alpha Trion, petitioned him for the next Prime. By this time, he had met Megatron, a gladiator who spoke of freedom and equality. He had considered Megatron his brother and they went to the counsel to speak of their new direction. Orion sought justice through nonviolence, but Megatron was harsh, trying to wage a war that being Cybertron into the Golden Age. They seperated and it was a loss Orion and Optimus Prime felt throught the millenia.
