Darth Assaultus

Darth Assaultus was an extremely powerful Sith Lord who lived between 64,878 ABY and 143,729 ABY. He had the ability to see the future and then bend it like a flexible object so that it would work in his favour. He never lost a battle and conquered almost every galaxy in the universe. The two that remained free were the Milky-Way and Andromeda. Both of these galaxies put up a strong resistance and the Sith Lord grew to respect them and their defiance. However, he orchestrated a change. The human race of the Milky-Way would become primitives and would have to work their way back up through the universe. Andromeda's inhabitants were all made into animals and sent to live with the humans. Assaultus was finally killed by Rurhan Fett on Dagobah.
