On a recon mission Rattrap finally learns how to transform, but accidentally wrecks the mission. Humiliated and angry with his friends' reactions, he attempts to make a deal with Megatron.
Running from Vehicons, the Maximals find themselves in a giant spark extractor facility, surrounded by dead Cybertronians. When Thrust saves Blackarachnia, she realises that the sparks of their dead comrades are being recycled into drones.

The perilous arrival of the powerful transformer Botanica may give the Maximals a fighting chance in their attempt to re-balance Cybertron, turning it into the technorganic world the Matrix desires.
When Megatron resurrects the two greatest generals in Cybertron's history, Botanica - reluctantly - proves herself to be as good a warrior as a scientist. Optimus vows to rescue the captured sparks.
Megatron has been absorbing the sparks, intending to 'ascend' and become the most powerful, perfect being in the universe. Noble's sacrifice causes Nightscream to lash out, disrupting the process.
