Transformers: Generation 1

Part 1 of 3. Following a civil war on planet Cyberton, the heroic Autobots and the evil Decepticons are marooned and deactivated on planet Earth for 4 million years! Finally reawakened, the battle between good and evil continues on present-day Earth.

Part 2 of 3. Using their robotic powers to hide in plain sight, the Autobots and Decepticons disguise themselves as Earth vehicles, and their war between good vs. evil continues as the Autobots try to stop the Decepticons from stealing Earth's resources.

Part 3 of 3. The Decepticons' ship to planet Cybertron is complete, and the odds are stacked against Optimus Prime, Bumblebee, Jazz and the others in the battle to stop them. When an Autobot trap is foiled by the cunning Megatron, all seems lost...or is it?

Presumed to be defeated, the Decepticons have returned! After receiving a message from Shockwave on Cybertron, Megatron comes out of hiding and orders the construction of a "Space Bridge" to transport Earth's energy to Cybertron.

After his accidental transportation to Cybertron, Megatron returns- and he wants to get his hands on an anti-matter formula created on Earth that could mean limitless power for the Decepticons! Bumblebee and Spike race to warn the Autobots.

While protecting an Earth military plant from a Decepticon attack, Optimus Prime is severely wounded. His only hope for survival is a new Cosmotron unit. The good news is that Wheeljack's got one - the bad news is that it's in his lab back on Cybertron.

The Decepticons begin to siphon the Earth's heat from the Arctic Circle and temperatures worldwide begin to drop. But unknown to the Decepticons is what... or who... they are about to release from the ice.

Inspired by dinosaur skeletons, Ratchet and Wheeljack create Grimlock, Slag, and Sludge... the Dinobots! When Autobot forces are captured by the Decepticons, it may be up to the Dinobots to save the day.

Megatron scours the Andes in search of the Crystal of Power, an ancient artifact capable of unleashing mass destruction. To prevent the Decepticons from achieving their evil goals, the Autobots find and unearth the fallen Skyfire to join in the fight.

Optimus Prime assigns the Dinobots to guard a meteorite that contains new and unknown energy. Appealing to Grimlocks' simple arrogance, Megatron convinces the Dinobots to attack Optimus Prime and betray the Autobots.

Part 1 of 3. With help from a human scientist, the Decepticons enslave people through mind control to fight against the Autobots and generate enough power for Megatron's sinister plan: bringing Cybertron into Earth's orbit to steal all of its energy.

Part 2 of 3. With Cybertron now in orbit, the Earth is being torn apart by geological forces and natural disasters. A small Autobot team heads to Cybertron to stop Megatron, while the rest of the Autobots try to protect Earth. But is it already too late?

Part 3 of 3. On Cybertron, Spike and the small band of Autobots attempt to sabotage the Decepticons' hypno-chip and free the people of Earth. Meanwhile, Optimus Prime and the remaining Autobots on Earth continue to try to save the planet.

With Megatron presumed dead, Starscream makes his boldest grab for power yet, planning to destroy Earth and use the energy from the explosion to rule the universe. But an unlikely alliance between the Autobots and Decepticons may foil Starscreams' plan.

Deep in the "Demon Swamp" on the island of Bali, large robotic insects are eating everything in their path and terrorizing the islanders. Megatron realizes they are an ancient breed of Decepticons, and forms an alliance with these powerful Insecticons.

As Optimus Prime and Megatron prepare to face off in a duel, Megatron secretly plots to unleash the latest addition to his Decepticon army - the Constructicons - along with Devastator, a Decepticon unlike any the Autobots have ever seen before!
