There are many interesting fanfictions about Vampire John and Sherlock. One common theme could be how Sherlock, with his brilliant deductive skills, discovers John's vampire nature. It might involve a lot of mystery-solving around John's condition and how they navigate their relationship in the face of this new revelation.
Some fanfictions might explore the idea of John struggling with his vampire identity while Sherlock tries to help him. Sherlock could use his knowledge of science and logic to find a way for John to co - exist with his vampiric side, all while dealing with the potential danger that John's new nature might bring to their lives.
In such fanfiction, perhaps Vampire John has special powers that come in handy during their adventures. For example, his enhanced senses could help them in solving crimes more quickly. And Sherlock, being Sherlock, would be both intrigued and a bit cautious about this new aspect of his friend.
The appeal lies in the unique twist it gives to the classic characters. It combines the mystery-solving aspect of the original Sherlock Holmes concept with the allure of the supernatural. Vampire John adds an element of danger and mystery.
Well, 'Moonlit Mysteries' is a fanfiction that you might enjoy. In this story, Sherlock's vampire identity is a well - guarded secret at first. John slowly starts to suspect something is different about him. The way the author builds up the tension and the slow - burn romance between them is really engaging. Also, 'Vampiric Intellect' is a story where Sherlock's vampire abilities enhance his deductive skills in a very interesting way, and his relationship with John is at the center of the plot.
A less obvious but still common theme is the exploration of morality. Being a vampire or a werewolf often blurs the lines of right and wrong. Sherlock and John have to navigate through this moral grey area. In some fanfictions, they debate whether it's okay to use their supernatural abilities for personal gain or for the greater good. This exploration adds depth to their characters and the overall story.
The 'slow - burn romance' is really common. It takes time for John to fully accept Sherlock as a vampire and for their relationship to develop into a romantic one. Also, the 'discovery' trope is often used. John discovers Sherlock's vampire nature in different ways, like stumbling upon him feeding or noticing his inhuman abilities. This leads to a lot of interesting plot developments as John has to come to terms with it.
One possible fanfiction could be about Sherlock and John investigating a mystery related to a 'carve baby'. Maybe it's a strange art piece or an object with a hidden meaning that they need to decipher.
I also like 'Fangs and Fur'. It delves deep into the lore of vampires and werewolves in the context of Sherlock and John. The story shows how their different natures can either clash or complement each other. It has some really intense action scenes and emotional moments that keep you hooked from start to finish.
There is a fanfiction named 'Dangerous Discoveries'. Sherlock and John are on a case in an old factory. They accidentally set off an old security system that releases some noxious gas. John inhales a bit too much and starts to choke. Sherlock, trying to find a way out, gets cut by some sharp machinery parts. Their survival instincts and mutual care are depicted well in this story.
In many Sherlock/John fanfictions, their care for a baby can be quite heart - warming. Sometimes it's a case - related situation where they end up taking care of an orphaned baby during an investigation. This often shows a softer side of their characters, especially Sherlock, who might seem initially clueless but gradually grows attached.
In many Sherlock/John fanfictions, Sherlock's actions towards John show deep affection. For example, he often goes out of his way to protect John from danger. He might put himself in harm's way just to keep John safe, which can be seen as a sign of love. Also, his jealousy when John pays attention to others can be an indication. In some fanfictions, Sherlock is overly possessive of John's time and attention, much like a person in love would be.
The 'carve baby' in the fanfiction could be a symbol. It might represent something from Sherlock and John's past, like a case they worked on long ago that had an unresolved element related to a carved baby - like object.
