Before, Optimus Prime is the awe-inspiring leader of the Autobot forces. Selfless and endlessly courageous, he is the complete opposite of his mortal enemy Megatron. Originally a mere civilian known as Orion Pax or Optronix, he was chosen by the Matrix of Leadership to command, the first in a number of heavy burdens he has been forced to bear. Another is his bringing of the Transformers' conflict to Earth. Every casualty, human or Cybertronian weighs heavily on his spark. He does not show this side to his soldiers and never succumbs to despair. The Autobots need a decisive, charismatic leader and that is what he gives them. It was that leadership which turned the tide of the Great War. There is no one more aware of the contradictions inherent in his station and character than Optimus himself, but he cannot allow himself much room for hesitation or doubt in the moment. Optimus feels most in his element when he's taking bold action and forging ahead... even if the negative consequences left in his wake become yet more burdens on his noble spark. Once the war is over, it gave Optimus a lot to think about. Much to consider, and a lot to do. While Rodimus takes a crew on a quest aboard the Lost Light, Optimus Prime stays behind on Cybertron, He shifts over to lead the companion, where he deals with planetary politics and Earth. Optimus prime ends the war, and splits the matrix of Leadership. Believing that Cybertron needs a new beginning rather than a military commander-turned-ruler, he splits the Matrix of Leadership, gives halves to Bumblebee and Rodimus, and declares that "Optimus Prime is dead" so that his old civilian identity, Orion Pax, can be reborn, While Rodimus takes off on the starship Lost Light to search for the Knights of Cybertron (the core premise of the MTMTE series), Optimus remains behind to help rebuild Cybertron and manage the planet's returning population, leaving the space exploration to Rodimus's crew. Orion Pax is a soft-spoken, considerate mech, he has a high sense of justice and a tendency to take on more than he should. Orion is still, very Selfless and endlessly courageous, that nobleness fire in his spark still burns. He has a deep respect for warriors, his friends and the bots he'd consider his family. Orion is very level-headed and takes more time to think on decisions rather than rash, quick choices. He is a towering, sentient robotic lifeform from Cybertron who transforms into a heavy-duty semi-truck. Renowned for his deep, resonant voice, he is the ultimate symbol of justice, bravery, and self-sacrifice against the tyranny of Megatron and the Decepticons. Traditionally features a red and blue color scheme with a silver faceplate, glowing blue eyes, and windows on his chest that used to house the Matrix of Leadership.
