Beast Machines: Transformers

Optimus destroys Cybertron and realises that the oracle sent them to Earth to bring back organic life, for there to be a balance between technology and organic. 

The Maximals attempt to infiltrate Megatron's former fortress, only to have their mission threatened by their supposed new ally! 

Blackarachnia finally revives Silverbolt, although he is not happy with his new form. 

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

A seemingly empty spaceship crashes onto Cybertron. When Optimus re-formats the transformer she joins the Maximals. Her name is Botanica. 

Megatron unleashes a new set of generals who are not exactly as they appear! 

Desperate to thwart Megatron, the Maximals search for the missing Sparks. 

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

In the wake of Megatron's demise, something horrible haunts the planet Cybertron. 

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

Horribly outnumbered, the Maximals make their final stand in a desperate attempt to protect the sparks. 

With the others Maximal's sparks taken by Megatron and now having the body of Optimus Primal's "Optimal Optimus" from the third season of Beast Wars, Optimus has to face Megatron alone. Megatron absorbs the sparks and then Optimus pushes him into the planet's organic core, reformating Cybertron and destroying both Optimus and Megatron.
