Orion Pax | Part 1

Optimus Prime has lost all memory of ever being a Prime after using the Matrix of Leadership to send Unicron back into stasis; his memory has been reset to when he was still the data clerk Orion Pax. Megatron takes advantage of this, telling "Orion" that the Autobots are evil, taking him onto the Nemesis and setting him to work on a project deciphering Autobot enscriptions from the Iacon records. Back at base, the other Autobots are distraught at this turn of events, and upon discovering that Jack has the Key to Vector Sigma, they hatch a plan to get their leader back.
