Formerly a police officer by the name of Orion Pax, Optimus Prime is the leader of the Autobots. The first true heir to the title of "Prime" and holder of the Matrix of Leadership in millennia, Optimus' commitment to freedom and equality for all sentient beings is backed up by incredible leadership skills that allowed him and his forces to hold the line against the tyrannical Megatron and his Decepticons for millennia. Now that the war is over, however, Optimus occasionally feels at a loss with what to do with himself in this time of relative peace.
After contact was restored between Cybertron and several of its long lost colony worlds, Optimus found that many of the inhabitants of these colonies viewed him and the corrupt Primes of old as holy figures. While Optimus has always struggled to reconcile who he is with the dark legacy of the title he holds, some worry that the worship of the colonists has gone to his head, leading him to repeat the evils of his predecessors. Of particular concern is his annexation of Earth into the Cybertronian Council of Worlds, a move he claims was for the planet's own protection but many others see as the beginnings of a new empire...
Though initially interested in more intellectual pursuits during his education, Orion Pax ultimately became a rising star in the Cybertronian police, eventually becoming captain of the Rodion police department. While working as a cop, he learned of a miner and political writer by the name of Megatron who had been arrested unfairly. After getting Megatron released, Orion encouraged him to continue his fight against the Functionism that purveyed Cybertronian society, having been quite inspired by his words. After discovering just how corrupt the Cybertronian senate was, Orion forced his way into the Grand Imperium to make a defiant speech calling out the planet's leaders. Touched by Orion's speech, Senator Shockwave befriended the officer, the two bots becoming close allies in the struggle against the senate's corruption. After the senate discovered Shockwave was plotting against them, they had him arrested and punished by their goons, forcing Orion to go on the run before making contact with Zeta, another ally of Shockwave's.
After Megatron and his new Decepticon army murdered the majority of the senate and their leader Sentinel Prime, Zeta was chosen to become the new Prime and lead the new, supposedly better senate. Though Orion believed Zeta was a force for positive change, he eventually proved to be just as corrupt and evil as his predecessors. Forming an alliance with Megatron, Orion helped to overthrow Zeta Prime but was betrayed by Megatron. Shot and left for dead, the wounded Orion discovered the long lost Matrix of Leadership and was revived as Optimus Prime. With the Decepticons having become the thing they once stood against, Optimus Prime took up leadership of the Autobots and waged war against them, even as the conflict all but destroyed Cybertron and spilled off onto other worlds.
After four million years, the war finally came to a head on Earth. After a traitor in the Autobot's ranks gave the Decepticons intel that allowed them to make an all out attack against key Autobot outposts, Optimus Prime was nearly killed but made a miraculous recovery just in time to drive the main Decepticon force off Earth, critically injuring Megatron in the process. Unfortunately, Prime didn't recover in time to prevent widespread chaos and destruction all across the planet. Without Megatron's leadership, the Decepticons forward momentum stalled, leading to the Autobots declaring victory over them within a matter of years. In the aftermath of the war's final battle, Cybertron was restored and the Matrix was broken in half. As millions of Cybertronians who'd remained neutral returned home, Optimus found that they viewed him as a symbol of the war that destroyed their planet. Leaving the halves of the Matrix behind, Optimus relinquished his title and went back to Orion Pax before leaving Cybertron to roam the stars in hopes of maintaining peace. While off in space, Orion discovered a plot engineered by his old friend Shockwave, one that he eventually found would lead to the destruction of time and space. Reclaiming his title, Optimus teamed up with a repentant Megatron to stop Shockwave's scheme.
Aw Yeah Revolution!
