Fiction

Beast Wars: Uprising

Following the disastrous Scouring of Nebulos in 2031, the Confederacy decided that the Great War was over, and enacted their decree by forcibly imposing an armistice on the two factions. Under this treaty, the Transformers were limited to an Allowed Zone consisting of Cybertron and nine colony worlds of their choosing. Micro-Aggressions One of those worlds was the remote colony planet Rebirth, home to a civilization of tiny Cyberdroids that became replacements for the ailing Nebulan 'masters. When the planet had fallen to Galvatron's forces, the Decepticon leader and his forces turned their attention to the human blockade. A Brush With Infamy–Prologue

In 2033, Galvatron organized a massive invasion fleet. In the ensuing fight, the CTCF triumphed and easily routed the Cybertronian forces. Micro-Aggressions One participant in the battle, Trypticon, was gravely wounded during the hostilities, only surviving after Full-Tilt modified himself to serve as the giant's T-cog. Intersectionality

As a result of this violation, the humans revised the terms of their armistice: the Transformers would have their allowed space cut in half, now restricted to Cybertron and four colony worlds. After a ten-day evacuation period, the five worlds outside the new restricted zone were sterilized. As punishment for his deeds, Galvatron was vivisected by Builder scientists, with his remains processed into the deadly G-Virus. The Maximals and Predacons were taught to remember Galvatron as the most evil Builder of them all. Micro-Aggressions
