"Scarlet" as a name has always invoked an air of sensuality and mystery. Usually a female-oriented trope, the name "Scarlet" often denotes a woman with a fiery, indomitable personality and complicated morality. If she's a hero, she'll be on the aggressive side. If she's a villain, a Heel–Face Turn is never out of the question. As one can expect, she is often a Lady in Red and/or a Fiery Redhead, especially if "Scarlet" is actually a nickname or codename. While male examples exist (Captain Scarlet and The Scarlet Pimpernel come to mind), they usually have a much different feel, playing up the boldness of the color red rather than any direct sexualization.
