A Sith Super-Overlord was one of the ranks of the Sith. It was below Sith Mega-Super-Overlord, but above Sith Overlord. Darth Elmo was a Super-Overlord before he bestowed the title of Mega-Super-Overlord upon himself. Sometimes a Sith Super-Overlord would be given the opportunity to start his own empire, this would only happen if they were really evil and had destroyed more than 1000 planets in les than 10 years. Because of this rule most Sith were forced to wait until they were promoted to Sith Mega-Super-Overlord before they could rule an empire.
