Annie Wilkes (Misery)
Annie Wilkes is abusive, which is unacceptable, however, as a character, she’s fun in a horrifying way. She’s a crazed Paul Sheldon stan who manages to rescue him and his manuscript and tortures him when he writes profanity into his manuscript and kills off Misery, the protagonist. She makes the list because you have to be a tiny bit badass to pull off some of the crazy stuff Annie does.
