Autobots, Decepticons, Predaking and Predacons form an unlikely alliance to battle a resurrected Unicron.

When Scientists discover Sun Spores, an alien plague that instills a hatred so overwhelming that anyone infected won't stop until everything in their path is destroyed. Soon, the scientists decide that it's time to rid the Earth of the Transformers and plan to use Optimus Prime's lifeless body to lure every Transformer to their lab and infect them with the Sun Spores. When the Sun Spores outbreak rages out of control, the universe's only hope is to revive Optimus Prime. But even if Optimus recovers, he and his Autobots will need to rely on Galvatron and the remnants of his Decepticons to help reclaim the Autobot Matrix of Leadership from an infected Rodimus Prime and use it to unleash a new Golden Age of Cybertron.

In the aftermath of the Titans' conflict that concluded into Optimus Prime's death, the rest of the Transformers must stand together in order to stop Megatronus from wiping out their species forever. During their search for the Requiem Blaster, more mysteries about Cybertron’s past will be uncovered, and a new Prime will be chosen.

Since acquiring Dark Energon - the very lifeblood of the mythical being Unicron - the Decepticon leader Megatron has worked tirelessly to uncover its secrets in an effort to finally wield its great power. With the strength to absolutely corrupt any amount of Energon, even bringing zombie-like life back to the dead, Dark Energon is the ultimate weapon against the Autobots. Now it's up to the heroic leader of the Autobots, Optimus Prime, to stop his old nemesis once and for all, no matter the cost. But does the Autobots' true key to salvation lie in the trusted hands of a teenaged boy named Jack?
