My favorite Disney villain, the Dark Fae queen, Maleficent.  

What makes Sleeping Beauty such a great film is it is not a princess and prince love story. They are merely pawns in the real plot - a battle between the Dark and Light Fae. To think it all could have been avoided if they'd simply sent Maleficent an invite. She probably would have given Aurora a really badass gift. Dumb humans.

(note: I have never seen the live action film. Why mess with perfection?)
