The Ultimate Doom: Search (Part 2).Cybertron's nearby presence has sent Earth and everyone on it into chaos. The Autobots and the Dinobots have their hands full trying to protect innocents and themselves from every possible natural disaster. Undoing what Megatron has done is a major priority, but so is rescuing Sparkplug. He is currently a Decepticon prisoner on Cybertron, and the Autobots aren't about to hang him out to dry. Spike and an Autobot team are sent out, but Sparkplug is still wearing a hypno-chip meaning more danger than expected. Meanwhile, the Earth-bound Autobots try to stop Megatron.
