Transformers: Prime

With no memory, Optimus believes he's Orion Pax and falls under Megatron's influence. Jack and Arcee travel to Cybertron to reach Vector Sigma, and the knowledge Jack brings back restores Optimus to himself. The Autobots and Decepticons start hunting Cybertronian relics hidden on Earth, including the Omega Keys, which lead to the Omega Lock, a device that can restore Cybertron. Wheeljack, Shockwave and Smokescreen join the story, and Megatron goes after the Star Saber. In the finale, Megatron uses the Omega Lock to try to turn Earth into a mechanical planet. Optimus destroys the device and saves Earth, but dooms Cybertron. When the Autobots get back, the Decepticons have built a fortress right outside their base.
