1 Michael Myers\n\n While he seemed like a scary babysitter killer in the first movie, he became a little more supernatural as the series wore on. Michael has been in 12 out of the Halloween movies, including both reboots, and he might be the most unstoppable slasher villain in history.

Halloween (1978), A Nightmare on Elm Street (1984), and Scream (1996) are classics that have been popular amongst people, especially during October.
