Darth Evil

Darth Evil was the darkest most evilest Sith ever. And she didn't have destroy planets or kill anyone either.

One of the greatest (in terms of eviltude) Siths of all time Darth Evil was a woman. And not just any woman, the woman of your dreams, and mine, and everyone elses. She was a woman of such extreme hotness and passion that even someone as sexually ambiguous as Goldenrod would be completely overwhelmed by mad, umm... relational urges at the very sight of her. And that was her thing, she was smart, gorgeous and perfect in everyway but she never put out. Not to anyone. Not ever. Such was the greatness of her evil.

Legend says that she would appear to anyone as the very realisation of their most covetted fantasy, and play out a whole fairy tale for you, without the 'happy ending'. Many Jedi came over to the Darkside sheerly out of the emotional stress of meeting her. Many Sith have destroyed planets just at the sight of her. did I mention she was evil?

Anyway, legend also has it that she could not die (Even death was afraid to come near her), so she might still be around today. That girl next door who likes you? Could be her so watch out.
