Optimus Prime is the official leader of the Autobots during the war on Cybertron, as well as the leader of Team Prime. Before the Great War, Optimus Prime was originally 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 Pax and believed in Orion to become the next Prime. Orion Pax was chosen by the High Council and became "Optimus Prime," upon being entrusted with the Matrix of Leadership by Primus himself. Years of war against his old friend/rival, Megatron, have brought Optimus and his team to Earth. On Earth, Optimus fights with his team to survive and to end the brutal war, against their enemies, once and for all. Optimus and his team met new species on Earth and tried to. During their fight against the Decepticons on the planet, Optimus and the other Autobots were subject to many disadvantages, managing to pull through every time in their various missions in order to stop Megatron's exploitation of Earth's vast Energon resources. Eventually, Optimus then used the Omega Lock to restore Cybertron where he and his team currently work to rebuild the planet.
