A good horror character makes the audience fear them. They need to have a background story to them as to why they do what they do, such as they were bullied as a child and they are going back to kill the bullies, something along those lines. They should have a different thinking style to other people, should be evil thinking. Take Michael Myers in Halloween, he wears a mask that has no facial features, a character in a horror that has no face visible can be more scary then when you can see the murderer. At the very start of the first film he goes upstairs and stabs his sister to death. We then know that he is emotionless,his family isn't worth much to him, but we don't know why he did this. Another good character is Jigsaw from saw, he is a very mysterious person and captures people who have done bad things and tortures them. He also uses a doll which is creepy looking and makes the audience fear it. Further scary characters are Freddy Kreuger in friday 13th and the Texas Chainsaw Massacre.
