After the Combiner Wars ended, Cybertron started to be rebuilt. However, an undead Starscream has taken control of 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.
