Third Cybertronian War
From Multiversal Omnipedia
The Third Cybertronian War was the third and longest-running war fought among the Transformers, beginning after the Decepticon (Destron) development of transformation and the rise of Megatron to power. Theoretically, this war ended after Unicron's attack on Cybertron (Seibertron) in 2005, but in reality the fighting continued for many years more, finally ending with the Pax Cybertronia. This conflict later became known as the Great War.
