99 Horror Villains for Your Next Script

Every great horror story needs something or someone to fear. Whether it’s a masked killer stalking victims in the night, a ghost haunting an old house, a creature lurking beneath the water, or a monster that has been unleashed, the story needs a terrifying threat to drive not just the conflict against the protagonist(s), but also to instigate the fear within the audience watching.

From Michael Myers in Halloween to Pennywise in It, the Xenomorph in Alien, Hannibal Lecter in The Silence of the Lambs, the shark in Jaws, the demon in The Conjuring, a wish come terrifyingly true in Obsession, or the strange entities in Backrooms, the horror genre has given us some of cinema’s most unforgettable antagonists.

The trick for screenwriters is finding their own versions of threats while giving audiences something or someone they haven’t quite seen before.

These 99 terrifying horror antagonists and villain characters aren’t finished concepts. Instead, look upon them as ingredients. Choose the one that scares you or fascinates you the most, and then find your own angle and start asking one of the most important development questions all screenwriters should ask themselves: “What could I do with this that the audience hasn’t seen before?”
