Every Disney story needs a good villain. When I was a kid, I remember being absolutely terrified of Ursula, but without her, there wouldn't really be any plot to "The Little Mermaid." And what would "Lion King" be without Scar? "Snow White" without the Evil Queen? There totally has to be a character to root against when you watch the movies.
You've probably seen most, if not all, of these classic Disney movies, and I'm sure you recognize these villains. But just how well do you know them? Do you have an evil streak yourself?
