When it comes to slasher villains like Jason Vorhees or Michael Myers, what precedes their reputation is the mask they wear on their faces. While the hockey mask and white cast of William Shatner's face are indeed iconic, most would not consider them to be all that creepy, at least when they are not on the face of their respective owners. In fact, the horror genre is home to many a masked villain, some wearing masks that are far creepier than the likes of Ghostface and Hannibal Lecter.
