THE ULTIMATE DOOM: Part 3

The alarms scream in the Shockwave's base, as Brawn, Bumblebee and Spike try to escape. They are cornered by Shockwave, Soundwave and some Decepticon Air Warriors, but Skyfire, Trailbreaker and Wheeljack rescue them. Skyfire stays behind to cover their escape and leaves also when Shockwave blasts a wall down.

The Autobots are pursued by Decepticons in the air and on the ground as they race towards Wheeljack's workshop. Wheeljack examines the Hypnochip information and learns how the mind-control devices work.

The Earth-bound Autobots race across the ocean ahead of a giant tsunami towards a Decepticon Hydroelectric Energy Collector. Starscream bickers with Megatron at the Collector, while Megatron orders Archeville to stay away from Starscream.

Rumble spots the approaching Autobots shortly before they are washed ashore by the wave. They see the Decepticons retreating just as they emerge from the water.

Dr. Archeville flounders in the ocean screaming for help, and help comes from a most unexpected source, Starscream, who has plans for the Doctor and his inventions.

Back on Cybertron, Wheeljack builds a device that will break the Hypnochips' hold on the human slaves, which uses Audio-Disrupter Waves. They break into Shockwave's HQ again to test it on Sparkplug, and narrowly keep Sparkplug from executing Spike. The Autobots flee with Sparkplug and fly aboard Skyfire back to Earth

Megatron loads his final shipment of Energon into his new Cargo Ship, while Starscream tries to drain Archeville's lifeforce into an Energon Cube. Megatron overhears more of Starscream's treachery, but and urgent report about the slave malfunctioning, allows Starscream to escape. The "malfunction" was the invisible Mirage forcing the slaves to exit the battlefield, so that the Autobots could attack.

The Autobots fight desperately, because Cybertron's next orbit will destroy the Earth. Skyfire arrives with Wheeljack blasting Audio-disrupter Waves, and freeing all of the human slaves.

Megatron boards his cargo Vessel, filled to capacity with Energon, abandoning his troops on the dying Earth. The Decepticons fly after him. While the Autobots focus all of their fire upon the Cargo Ship. The Energon Cubes explode with enough force to blow Cybertron out of Earth's orbit, ending the cataclysms.

Debris from the Cargo ship drifts through space, as Megatron awakens and vows to be avenged for this defeat.
