Spoiler Warning!!!
Here's my newest choice, from a more modern day movie.
Lots o' Hugging Bear (AKA Lotso) from Toy Story 3Seriously, this is the one you NEVER see coming and he makes a great villain. His backstory is basically that he was a toy that was replaced, and I mean completely replaced, by his owner by just having one of himself being bought. As such, he becomes cold-heartened and takes over the daycare that the toys we know from the movies end up in.
He set up the system and so that the toys are played with toddlers. (Trust me, from their perspective, it doesn't look pretty.) Also, when Buzz tries to confront Lotso he actually turns Buzz against the toys, even to the point where Jessie's love for him doesn't help bring him out of it. (*sarcasm* Gee, and that usually works SO well, doesn't it? */sarcasm* (Seriously, a number of fanfiction writers could learn something from this.))
Also, near the end, it actually looks like he is going to help them, but doesn't, despite the fact that they risked their necks to help him.
And even though he gets humiliated at the end, he just makes a great villain. He's definitely one of the best of 2010.
