I'm a Star Wars fan, however my knowledge of Star Wars comes from the movies, not the numerous books, fan websites, and other sources of information that allow one to talk about the Star Wars "Universe."
There have not been any female villains in the Star Wars movies. We have the Emperor, Darth Vader, Count Dooku, and recently Kylo Ren.
In the Star Wars universe are there female villains and, if so, ones that can be just as uncool as Darth Vader? Or is the Dark Side something into which only men are seduced?
