Several decades after the Great War between the Autobots and the Decepticons on Earth, the two factions have disbanded and a three member ruling council rules in place of the absent leaders Optimus Prime and Megatron. An uneasy peace has been created on Cybertron, but the rise of the Combiners threatens to bring it to an end.

After the Combiner Wars ended, Cybertron started to be rebuilt. However, an undead Starscream has been reincarnated as Trypticon, wreaking havoc around him. To combat this menace, Windblade gathers up a ragtag team of Transformers, including Optimus Prime and Megatron, to resurrect an ancient ally. And while some may be forever changed by the events, others may not emerge with their sparks intact.

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.
