What makes a fictional creature scary? 10/18/17

In stories, a malformed creature is often seen as scary, and this creature often does horrible horrible things. But, in some stories, the creature is scary. For some creatures, all it takes is their presence.  The hand slinging slasher is a fictional character often characterized as horrifying. His shear shadow is enough to scare the main protagonists seen in the Sponge-Bob television series. He appears to be an ex fry-cook of a grave-yard shift's past.  He features a Burger Flipper, instead of a traditional hand, red glowing eyes, and a hunched back. This character was definitely not produced for the faint of heart. I would certainly say the Hand Slinging Slasher is a staple of the horror series.
