Fear, often referred to as Dread, Horror, Phobia and Terror, is defined as an unpleasant emotion that leads people to believe that someone or something is dangerous, or may be threatening, or it could lead to possible pain. Many scientists believe that someone would be put in a certain kind of stimulus that when the threat of danger arises, the person would try to find any way possible they could to get out of that situation. Because of this concept, many villains use this unpleasant emotion to their advantage whether to ensnare their victims, or to manipulate further to a dark end.
