Cybertron: An Optimus Prime Love Story

The Great War

The war was brutal and largely one-sided; the Autobots retained control of two cities, Iacon and Kalis, while the Decepticons took over the rest of the planet. Those that don't join the war quickly died in the crossfire. Out of desperation, the Autobots launched the AllSpark into space to keep it safe from the Decepticons. Megatron ordered Starscream to give him access to Trypticon Station's stockpile of Dark Energon, a power-enhancing substance. The Decepticons consumed the Dark Energon and became extremely powerful, gaining a combat edge and overwhelming the struggling Autobots. Megatron then seeks control of the Plasma Energy Chamber (a device that distributes Energon across the planet) at Cybertron's core, planning to flood it with Dark Energon, which would permanently empower his own forces while poisoning Cybertron and starving the Autobots to death. He murdered Sentinel Prime in the process and stole the key to the Chamber concealed within Sentinel's torso, but before he could access it, the Autobots reactivated Omega Supreme, an enormous ancient Titan that transformed into both a rocket ship and a city. Omega Supreme took away the Plasma Energy Chamber and attempted to fly it to safety, but Starscream leads an aerial assault which took him down, and after Megatron empowered himself with Dark Energon, he effortlessly defeated the Autobots and Omega's robot mode was damaged beyond repairs. He flooded the Chamber with Dark Energon and sends it back into Cybertron's core.

As the Dark Energon flowed throughout Cybertron, Optimus Prime ventured into the core to fix the it, accompanied by the Autobots Bumblebee and Jetfire. Once they found it, Bumblebee extracted the Chamber, stopping the flow of Dark Energon, while Optimus received a mental communication from the core itself, who was in fact the spark of Primus, the creator of Cybertron and the Transformers. Primus stated that he will eventually be able to heal himself, but the process will take centuries, and in the meantime he will be unable to generate enough Energon to sustain the population he currently does, which will cause Cybertron to become cold and barren, so the Transformers will either have to abandon Cybertron or risk starvation. Primus bestowed Optimus with the Matrix of Leadership, a small fragment of his spark which contained the collective wisdom of all past Cybertronian leaders and the original 13. Optimus called for a mass exodus of the Autobot army, but most of the ships were shot down by Trypticon Station.
