Welcome to the Beast Wars section of the Museum.  Millions of years before the Autobot's and Decepticon's restarted their long war on planet Earth, another group of Transformers Crashed on Earth and began a long struggle that nobody ever knew about until those combatants returned home.  These were the Beast Wars.  This war was not started by the Autobot's and Decepticon's ancestors, but by their Decedents, who now call themselves Maximal and Predicons.  Transported back in time these Transformers fought for the control of not just the Earth, but of the Universe as well.
