Not long after Megatron's demise and the restoration of Cybertron, the Autobots celebrate as Optimus Prime promotes Bumblebee (Transformers) to warrior class. The festivities end, however, when Optimus sets out on a journey to find the Spark (Transformers)#Transformers: Prime, the source of new life on Cybertron, and takes Wheeljack with him to find it so that new Transformers can come into being. Ultra Magnus is left in charge in Prime's absence to hunt down the missing Shockwave (Transformers) and Starscream with the other Autobots. Meanwhile, on Earth, at the bottom of the ocean, Megatron's consciousness is reawakened by Unicron, who seeks to destroy his arch-enemy Primus (Transformers), the very core of Cybertron, and requires Megatron's body to do so. Unicron reformats Megatron's lifeless husk into a perfected body with new upgrades, before heading to Cybertron. In the meantime, Ultra Magnus and Smokescreen (Transformers) continue to search for the fugitive Decepticons in the Sea of Rust, but are soon attacked by the Predacons Sky Lynx and Darksteel. After a brutal fight, Magnus is severely damaged and Smokescreen is barely able to save his life and make it through an emergency space bridge with him. The damage is so critical that the Autobots are forced to call in Ratchet (Transformers) from Earth for assistance while the Autobots deduce that the two new Predacons must be creations of Shockwave. Meanwhile, Shockwave and Starscream are revealed to have restarted "Project: Predacon" and plan to create an army with Skylynx and Darksteel being their first creations.
