Optimus Prime and his team of Autobots were sent along in the Ark to destroy the giant meteors that threatened Cybertron's existence. The launch site they left from was the Autobase.
Vorns later, while many of the Autobots and Decepticons lay deactivated in the Mount St. Hilary, Perceptor and Lord Straxus led their respective forces in the on-going war on Cybertron. Perceptor and his team of Autobots, including Blaster, fought from the Autobase. The Smelting Pool!
During the time of Unicron, Galvatron took Hook, Line, and Sinker and attacked the Autobase. The entire place burned under Galvatron's wrath, and Emirate Xaaron was made to flee, at the insistence of his fellow Autobots, through the catacombs, under the Autobase's floors, in pursuit of Primus' face.
The Autobase never again was used in the comics series.
