Here we can discuss Disney villains! Who are your favorites? Who do you think is the most evil/scary/funny? Who do you wish you knew more about? Who do you think is a poor excuse for a villain?
As far as scariest villains, for me, hands-down it's the Horned King and Chernabog! I would not want to be in a room with either of them! They're just plain scary! And, I mean, the Horned King wants to take over the world with an army of deathless warriors...and Chernabog has his demon minions...not people I want to associate with!
I can say that the Horned King is one of my favorite villains (although we don't know much about why he is the way he is), but apart from scariness level, Chernabog isn't really one of my favorites.
I really like Alameda Slim and Ratigan. I don't think that Alameda is the best Disney villain, but there's something about the yodeling cowboy that draws me to him! Ratigan is a bit more complex; he's definitely smart and his dry humor is great. He's elegant, and I like that.
I don't think I'm doing a good job of explaining why here, but maybe you all will do a better job of explaining your reasons! :)
