In the distant future the dark god Unicron wages a final war for control of the Universe. Autobots and Decepticons from parallel worlds are summoned to compete in the greatest battle of all times. And as they fight and die, Unicron grows ever stronger.
In order to satisfy the increased retail demand resulting from the success of Transformers Armada, Hasbro introduced the original Universe line. Figures from Armada, Beast Machines, Beast Wars, Generation 2 and even Generation 1 were repainted and sold anew, tied together by a storyline from 3H Productions, the company behind Botcon during these years.
