Vampires in fiction are mythical creatures often depicted as undead beings that sustain themselves by consuming the blood of the living. They are commonly characterized by their pale skin, sharp fangs, and aversion to sunlight. Popularized in literature and film, vampires have evolved from folklore into complex characters, often embodying themes of immortality, desire, and the struggle between good and evil. Notable works featuring vampires include Bram Stoker's "Dracula", which established many conventions of the genre, and Anne Rice's "The Vampire Chronicles", which introduced more nuanced portrayals. Vampires have also appeared in various media, including television series like Buffy the Vampire Slayer and movies such as Twilight, showcasing their enduring appeal in popular culture.
