Megatron leading Decepticon forces against the Autobot armies.

The Great War was the first and most violent outburst of fighting on the planet Cybertron between the Autobots and Decepticons. It began when Megatronus started his initial drive to overthrow the Caste system. Megatron's noble goal of being a Prime was corrupted by his jealousy over his friend Orion Pax, who being named the next Prime. This set the spark in the war and the Golden Age became history over time.

Fighting between the two factions lasted for several million stellar cycles, not even those who chose to be Neutral could avoid the war. Near the end, Cybertron was a barren, lifeless wasteland, devoid of Energon, forcing Optimus Prime to enact the Great Exodus, a mass evacuation of all Cybertronians to leave their dying world and find other worlds to seek refuge.

After the War on Cybertron, Optimus Prime went with his Team to Earth where they faced another battle against the Decepticons. The war came to a close when Megatron was killed by the Autobot scout, Bumblebee, and finally ended when the Decepticons were disbanded by a newly revived Megatron. The Autobots now live in peace with their fellow Predacons.

Years later, the Alchemor prison ship crashed, freeing the Decepticon prisoners it was carrying, and renewing the war again on Earth. Bumblebee and his team returned to Earth to defend it once again.
