Megatron boards the latest alien ship, using the golden disc to chart a destructive course back to Cybertron. With Optimus captured, the Maximals stand little chance alone against Megatron.
The dark secret of the Axalon's original space mission was to dump Protoform X, a Transformer with an indestructible spark. Now Protoform X has awakened, taking a new form.
A damaged stasis pod reveals a deformed, monstrous robot - dangerous to both Maximal and Predacon. Nevertheless, both Rampage and Silverbolt cultivate a friendship with her. However, the Maximal/Predacon war soon tears the lifeform apart.
The transwarp explosion wavefront heading to Cybertron is diverted by the Tripredacus Council so the Maximals can't detect it. They send Ravage, their own operative, to find and capture Megatron.
With Megatron in custody, Ravage reveals he plans to kill him - but the prisoner has saved a vital piece of the golden disc with a message from the original Megatron. It changes Ravage's mind. Silverbolt tries to turn Blackarachnia.
Rattrap sabotages Ravage's ship, making himself a hero. Blackarachnia's history lesson to Silverbolt is interrupted by Megatron, whose treachery sets off a time storm that could end all things.
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.
