When did the war start on Cybertron?

Answer 1

The war on Cybertron, known as the Cybertronian Civil War, began around the late 1980s in the Transformers lore, primarily depicted in the Transformers animated series and comics. It was characterized by the conflict between the Autobots, led by Optimus Prime, and the Decepticons, led by Megatron. This war resulted from deep-seated ideological differences, primarily over freedom and tyranny. The timeline varies across different media, but the conflict is often portrayed as a prolonged and devastating struggle that ultimately led to the evacuation of Cybertron and the arrival of Transformers on Earth.
