9 Scariest Horror Movie Monsters (2 of 5)

Pennywise—It (2017)

Pennywise is a shape-shifting connoisseur of your deepest fears, staging bespoke hauntings until that dread seasons the meat. The clown face is customer service, and beneath it is an ancient appetite of cosmic proportions. Red balloons are his RSVP and storm drains—his McDrive. If you see a paper boat drifting toward darkness, just go make a new boat, and move three towns over while you’re at it.

Chucky—Child’s Play (1988-)

Normally, toys are meant to bring people joy and laughter, but Chucky is special. Fueled by a serial killer’s soul and blessed with great comedic timing, this little redhead turns playtime into a bloody mess. The stitched upgrade makes him even worse! Chucky is scary because he desecrates innocence and because he moves when you’re not looking. If you have one of those at your house, lock the knives and anything that a 2-foot doll can stab you with, just to be safe.
