Shenanigans! Ursala sings, is charming, funny
and Eeeeeevil! G-d I fuckin' love her! How do you NOT sing along to "Poor Unfortunate Souls"?!?!?! It's brilliant! Hell, I'm singin' it right now!

That's part of my point. A villain - a truly GREAT villain - shouldn't have you singing their song. A good Disney villain should have that five-year-old in you cringing and cowering in fear. That's why, as much as I love Prince John from
Robin Hood and Ratigan from
The Great Mouse Detective (Vincent Price RAWKS!!!), I wouldn't put either in my top five.
Maleficent is still my fave Disney villian, though. But perhaps the most evil would be the Wicked Queen in Snow White:
"Bring me back her heart" (!!!!!)
Bitch asked for her stepdaughter's heart!! In a box! WTF!!
I'd place Snow White's Wicked Queen as a close (oh-so-close) second to Maleficent for a few simple reasons:
1) Both actively tried to kill the heroine. But Maleficent had the stones to curse her to death in front of the girl's parents AND a roomful of party-goers. And why? Because she wasn't invited. That's evil!
2) It's implied, but not openly stated, that Maleficent has more than a business relationship with the Infernal things that give her her power. Makin' whoopee with demons and such? Evil!!
3) Wicked Queen turns into an old lady. Maleficent turns into a dragon. A fucking
dragon! EVIL!!!
4) Maleficent actually uses a curse word. In a Disney movie.
EVIL!!!!That said, it's still close between the two. And I wouldn't belittle anyone who reverses the order.
Never heard of Ninja Scroll, though admitedly I'm not an anime fan - unfortunately, the look just turns me off. Akira's on my netflix list, though as its gotten such good reviews. I'm curious about Ninja Scroll now and will check it out too.
Definitely check it out. It's a gorgeous, well-made film. There's some scary shit to be seen within!
