Transformers: Five Faces of Darkness (1990)

The great war has ended. Unicron has been defeated, the Decepticons have fled and the Autobots are victorious under the command of a new leader. In the midst of the celebrations, the Autobots are suddenly attacked, leaving the Decepticons the obvious suspects. But the Decepticons are in bad shape, low in energy, without a leader and fighting amongst themselves.
