Optimus Prime

Optimus Prime is leader of the Autobots, he and his fellow Autobots form The Unit. He was once known as Orion Pax; a data clerk under the wing of Alpha Trion but became Optimus Prime upon being entrusted with the Matrix of Leadership. Years of war against Megatron have brought him and his team to Volantis. He is close friends with his fellow G.I. Joe partner Duke.

Cybertron
Orion Pax worked at the Hall of Records under Alpha Trion. Orion frequently read on Cybertron's past and became concerned with the corruption in high places and inequality. He shared these ideas with a gladiator named Megatronus, and the two believed they could rule together. However, when the two presented their ideas to the High Council they discovered they were quite different and Orion was made a Prime and renamed Optimus Prime. After Megatron dabbled in Dark Energon Optimus went to the core to try and purge it. For his bravery he was given the Matrix of Leadership by Primus himself. At some later point Oprimus launched the AllSpark to Theta Scorpieye to prevent Megatron to get his hands on it. When Cybertron eventually went dark Optimus led the Ark away. After thousands of years he made his way to Volantis.
