Actually Not a Vampire

Our heroine, Alice, has just met Bob. She's fascinated by him, but there's something not quite right about Bob. Maybe he spends all his time under an umbrella and avoids sunlight. Maybe he possesses seemingly superhuman strength, or maybe people have been mysteriously disappearing since he arrived.

Alice soon comes to the conclusion that Bob is a vampire and delves deeper into the matter. She eventually confronts Bob, only to discover... he's not a vampire after all. Maybe he's just a normal guy... or maybe he's something even more sinister.

This trope is for any instance where a character is set up as a vampire, and is then revealed not to be. It can lead to a massive awkward moment on Alice's part, or it may just serve to deepen the mystery if there is a real vampire on the loose.

Can also be Played for Laughs if a character accuses someone of being a vampire when it's quite clear to the audience that they aren't.

Compare/contrast Totally Not a Werewolf, in which the suspect is always a supernatural creature, just not the one they were thought to be. See also: Not Using the Z Word

Comics

 * In an old EC Comics story, the premise of a game show is to guess the job of a special guest. The contestants get steadily more panicky and more creative as they discover that their guest 'works with a red liquid' and it's not soap, or ink, or anything other than what they're thinking about... he's actually a phlebotomist (someone who draws blood).
 * Justice League, during their "International" period (also known as the Bwa-ha-ha era), ran an arc in which a region of Europe was overrun by "vampires". It's revealed that a mad-scientist had infected innocent people with an artificially mutated mind-controlling strain of porphrya, a blood disease that may have been the origin of the vampire myths.
 * One of the stranger storylines in Ruse involves an Uberwald-esque town seemingly empty by day but lively by night, and a nearby Gypsy caravan whose women are being kidnapped (and, eventually, Emma).
 * A subversion of sorts occurs in one Mickey Mouse story. Goofy befriends a man who has just moved into an old house in town, and who actually dresses much like the stereotypical Bela Lugosi sort of vampire. The man even admits himself that it is the look he is going for, and that everything else he does, from sleeping in a wooden box to keeping the curtains shut, is just a healthy way of life. Goofy believes it, and wants to try. Mickey is not so gullible, and repeatedly tries to prove his claim by throwing about typical anti-vampire stuff such as garlic and running water. In the end, however, all attempts fail, and Goofy becomes increasingly angry with Mickey for messing around. Cue Mickey convincing him to find the man where he sleeps at day and pulling the curtains. Sunlight shines on him... and nothing happens. Mickey admits defeat, and they both leave. As soon as they have, however, the man pulls away the fake window he had on his wall, with just a normal lamp behind it. He laughs at them in the final frame, and will presumably go on to act like the vampire he is now that the "hunters" are gone.
