Transformers: Beast Machines

After escaping from new foes, Optimus Primal, Rattrap, Cheetor and Blackarachnia are given strange new bodies by a mysterious supercomputer.

The Maximuls begin to understand and master their new bodies, only to find that Cybertron is now under the control of a old enemy.

The maximuls attempt to recover the cybetron backup files only to find them wiped clean. Blackaracnia begins having flashbacks of her missing comrades and heads out with rattrap to find some answers.

Rattrap uses a transformation enhancer, with disastrous results. Optimus tries to persuade Tankor to join them, successfully until Megatron regains control.

While patrolling, Optimus discovers a bat hiding in the shadows. At first he flees when Optimus tries to speak to him.

On a recon mission Rattrap finally learns how to transform, but accidentally wrecks the mission.
