If there's one thing that American Horror Story excels at, it's superfluous gore. But if there are two things it specializes in, they're superfluous gore and disturbing characters that will haunt you for the rest of your days. While there have only been five seasons of the show, there are way more than five villains. You've got your big, overarching bad guys, but then there are lots of evil characters that only appear in one or two episodes. Take a look here to see all the horrific baddies, ranked from "meh" to "holy sh*t this thing is terrifying."
