The Battle For Cybertron III.
The Ark returns to Cybertron, with the Autobots aboard reporting no apparent Decepticon activity. Meanwhile, on Cybertron itself, Chromia and another Autobot, Perceptor, break out of their captivity to try to warn their comrades of the Decepticons' death trap. Unfortunately, they are recaptured with Chromia being forced to watch as Shockwave destroys the Ark with his new laser snare cannon. The Decepticons revel in their apparent victory until the Autobots reveal themselves, with Optimus having earlier suspected their trap and ordered the evacuation of the ship's crew. A fierce battle occurs between both sides with Prowl taking a fatal shot from Shadow Striker meant for Optimus while Shockwave and Megatron initiate a secret plan. As the battle continues, Bumblebee, Hot Rod and Cheetor head off to the Well of the AllSpark while Hot Rod deals with Drift, who reveals he faked his defection to the Autobots...
