Who is the antagonist in Toy Story? The immediate answer is Sid Phillips. But is he really the main villain? Is it Potato Head and most of the other toys? Is it Woody himself?

1. a person who is opposed to, struggles against, or competes with another; opponent; adversary. 2. the adversary of the hero or protagonist of a drama or other literary work
And Woody does butt heads with Buzz for the first hour or so of the film. And Potato Head and his gang want to stop Woody from hurting any other toys. Sid doesn't seem so bad now does he? He didn't know the toys were alive! The meanest thing that he knew was wrong was steal his sister's toys.
