Our sense of smell is a more primitive sense, tied directly into our limbic system, which controls memory emotion. In this way, smell is a much more direct and powerful sense than sight. It evokes emotions and memories directly. Perhaps it's because the sense of smell is harder to visualize, but it tends not to show up as often among the suite of heroic powers. Heroes have magic eyes, villains have magic noses. You can also expect an unpleasantly creepy unwelcome love interest to spend a lot of time sniffing a girl. See also The Nose Knows for general strong-nose incidents.
