Slasher films typically feature codes and conventions such as a killer using a deadly weapon like a hook, knife, or chainsaw to threaten victims. The weapons are usually everyday items that audiences would recognize as dangerous, increasing the fear factor. Slasher films also commonly portray the killer as mentally disturbed or deformed to make them unpredictable and scary to audiences. Additionally, one of the main victims is often a helpless blonde female character who gets into dangerous situations out of ignorance. These elements help set the tone of danger and suspense in slasher films.
