With Scorponok defeated and the recent uprisings on Cybertron temporarily quieted, Hot Rod leads the Dinobots into the depths of Cybertron looking for the ancient Transformers, answers, and the Dinobots’ lost leader Grimlock. Prowl, meanwhile, struggles to keep the peace and makes sure his friends effected by Scorponok’s warrior gene have truly returned to normal. However, Soundwave is lurking in the shadows and using the recent chaos and Mayhem Attack Squad to blind Cybertron’s defenses and ready the way for Galvatron‘s arrival.
Meanwhile back on Earth, Optimus Prime is attacked by a 90’s Image Comics super-hero version of Spike while trying to talk some sense into humanity who has had their fill of being stuck in the middle of the Autobot-Decepticon war.
The story is a little weird (especially this version of Spike), but there are some nice touches including several familiar faces for longtime fans (along with those already mentioned we also get Silverbolt, Huffer, Inferno, and Blaster). For fans.
