I suggest "Tyrant" or "Tyranny" as the über term. Again, "evil" and "dark" really are givens. And I'd not fall back on Vader as an example too much because every Sith is a Dark Lord. In fact, Vader is really just a "Lord of the Sith" with very few uses of "Dark" prefixing that. Because "Sith" are "Dark Side" Force Users, so even the franchise's canon recognizes how redundant it is. I wager the most usage of "Dark Lord" in connection with Star Wars is mainly Fanon. IIRC "Dark Lord" and "Sith" were not even mentioned in the original trilogy.

How many "Galactic Overlords" do we properly have? Not counting the misuses? I suppose it could be a subcat.
