I like The Hunchback of Notre Dame, Oliver & Company, Atlantis, The Lion King, The Black Cauldron, etc. just as much, but I began paying attention to the Disney Princess films when someone on Villains Wiki noted that Hans was the third Disney Princess villain not to die.
Because of the Disney movies which I first saw when I was younger, I am really old-fashioned with villains, meaning I like to see them killed off in the end. I was one of the few who didn't deny that Queen Chrysalis fell to her doom, and wasn't disappointed when they confirmed that King Sombra was killed off. (Thumbs up if you've seen the show those two are from) So 9/12 Disney Princess villains are killed off in the end. I notice this more because it is getting rarer and rarer for any film or TV series these days to kill off its main villain, unless it's Marvel or 24. Mostly because fans like the villains so much they want them to "stay evil and stay breathing". Listen to the reactions when Ronan and The Other were killed off. The Other, who was barely noticed until his neck was snapped.
I could say what my favorite of the following are, but no one's probably interested to hear the favorite order of one who probably feels differently about something than they do. I remember this isn't that other wiki, where everyone respects each other's opinions even if they disagree. I can expect many will want to flame me for that and I ask that you keep all negative comments to yourself. Otherwise, I'll find an admin and request that they delete this blog.
