A masked villain, also seen as masked mystery villain,[1][2] is a stock character in genre fiction. It was developed and popularized in movie serials, beginning with The Hooded Terror in The House of Hate, (1918) the first fully-costumed mystery villain of the movies, and frequently used in the adventurestories of pulp magazines and sound-era movie serials in the early twentieth century,[3][4] as well as postmodern horror films[5] where the character "hides in order to claim unsuspecting victims".[6] They can also appear in crime fiction to add to the atmosphere of suspense and suspicion. It is used to engage the readers or viewers by keeping them guessing just as the characters are,[3] and suspension by drawing on the fear of the unknown.[7]: 135 The "Mask" need not be literal (although it often is), referring more to the subterfuge involved.
They are the often main antagonist of the story, often acting behind the scenes with henchmen confronting the protagonists directly.[3] Usually, the protagonists must discover the villain's true identity before they can be defeated.[8] Often, the villain will turn out to be either one of the protagonists themselves, or a significant supporting character. The author may give the viewer or reader clues, with many red herrings, as to the villain's identity - sometime as the characters find them and sometimes for the audience alone. However, the identity is not usually revealed to the audience before it is revealed to the characters of the story.[8]
