The Decepticons conquered Tlalak during the Third Cybertronian War, placing the planet in the care of a drone named Deceptitran, who used an army of robotic drones to keep the population under his heel. All was well, and the slaves toiled to produce energon for the Decepticons for many generations, but finally a rebellion rose up and a large number of the prisoners escaped. Deceptitran's distress call brought a party of Autobots to the planet, in addition to Megatron and a small number of Decepticons.
