For the longest time, clowns have been known for being more frightening than funny, especially when looking at the horror genre. There is a reason why the fear of clowns has its own term, "coulrophobia." What was once a cheerful figure with a big red nose and balloon animal artistry that served as entertainment for children's birthday parties has morphed into an evil monster with a talent for terror. The mention of clowns in horror conjures up popular picks like Stephen King's iconic Pennywise and, more recently, Art the Clown, and while they are scary in their own rights, there are far more clowns to fear in the genre.
