Evil clown
The evil clown (also known as the creepy clown, phantom clown, scary clown, or especially if their character involves terrorizing and murdering people, killer clown) is a subversion of the traditional comic clown character, in which the playful trope is instead depicted in a more disturbing nature through the use of horror elements and dark humor.
