For human beings, smell is the sense most directly linked to the brain, and the one that most quickly evokes memory. Therefore, it's no surprise that many characters in fiction are described as having a smell that instantly identifies them. An ex-lover may always carry the memory of her favorite perfume or his cologne, or a particularly strange character may have an equally strange, but distinct, smell to match. Another common usage is for a monster to be preceded by a certain smell, warning the heroes to its presence. This comes up often in works featuring characters who have an enhanced sense of smell or in works with animals, since most animals rely more heavily on their sense of smell than humans do. May overlap with Evil Smells Bad when the character is a villain.
