The Maximals are sent into a time storm after Megatron attempts to destroy one of their ancestors. But help has come from a very unlikely ally who finds that she's in the same boat as the Maximals.
Megatron uses a piece of Rampage's spark on a new blank pod in order to resurrect Dinobot as a Transmetal Predacon. While trying to stop him, Cheetor becomes critically injured.
Blackarachnia believes her relationship with the Maximals is not going anywhere, and decides to leave. On her way, she ends up playing a stalking game with Dinobot II.
One of Tarantulas' bugs is implanted on Optimus, which allows Quickstrike to control him remotely. Megatron thinks of a way for his powers to be on par with Optimus.
Deep within the depths of outer space an unknown enemy exists. Tigatron and Airazor are in a state of suspended animation and are transformed into a new entity known as Tigerhawk who serves as an emissary of the alien race known as the Vok. The Vok set out to destroy Megatron. In a state of panic Optimus Primal goes out to try and set the Vok straight and prevent the destruction of the time flow.
Inferno, Waspinator and Quickstrike search for a new base, while Megatron, Rampage and Dinobot 2 head underwater to the Nemesis. Depthcharge races after them, but is too late. The Nemesis rises, to Optimus and Tigerhawk's dismay.
With Megatron wreaking mindless violence over the earth and headed for the Ark, Optimus attacks, to no avail. All looks hopeless - unless the sudden resurgence of an old friend can swing the balance in the Maximal's favour.
Megatron has lost all hopes in taking over the Ark. However, he doesn't give up until the Maximals have definitely beaten him and makes a spectacular last-ditch effort for his goal.
