Beast Machines

While trying to recruit the Vehicons, the Maximals discover that they are being stalked by an all-new threat.

The Maximals are infected with a virus that turns them against each other; Optimus has second thoughts about his plan for harmony.

In the fight against the Transformers, Megatron creates two powerful generals who have won every battle so far; the situation seems hopeless for the Transformers, but the generals are not what they seem.

Having discovered the location of the missing Sparks, the Maximals race against time to stop Megatron from achieving his ultimate ascension.

Banding together inside Megatron's floating fortress, the Maximals must protect the Sparks from the depraved tyrant.

Heavily outnumbered, the Maximals make a final desperate attempt to protect the Sparks in Megatron's fortress.

With the other Maximals' Sparks being taken, Optimus is left completely alone for his encounter with Megatron.
