One common theme is the struggle between good and evil. Since Tara is often portrayed as a good character in the Buffyverse and vampires are typically associated with evil, the fanfictions often explore how Tara deals with the vampire elements, whether it's fighting them or trying to understand them.
One popular Buffy Tara vampire Tara fanfiction is 'The Magic Between Them'. It delves deep into the relationship between Tara and the vampire elements in the Buffy universe. It has great character development and some really interesting plot twists.
There are fanfictions where Vampire Willow and Tara are in a situation where they have to protect their friends from a new vampire threat. In some stories, they might also explore their relationship further, like going on a magical journey just the two of them to strengthen their bond.
In this fanfiction scenario, it could lead to a whole new dynamic in their relationship. Sookie, as a human, has her own set of morals and values. But becoming a vampire would change her completely. Eric might do it out of love or perhaps for his own gain. If he turns her, she would have to adapt to a new way of life, dealing with the thirst for blood and the vampire hierarchy.
I'm sure there are. The Twilight saga has a huge fan base, and fanfiction writers love to play with different scenarios. Bella's character is central to the story, and her relationship with vampirism is a key aspect. A story where she turns into a vampire as a result of suicide could be a way to explore deeper emotions, different character arcs, and new relationships within the Twilight universe. However, such a topic can also be quite dark and might be treated with different levels of sensitivity in different fanfictions.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions from various fandoms, including Buffy the Vampire Slayer which Vampire Willow and Tara are from.
The fanfiction could go like this. Sonic is on a mission in a spooky, abandoned town. Unbeknownst to him, it's infested with vampires. One of them manages to turn him into a vampire. At first, Sonic is horrified. His appearance changes slightly, with paler fur and redder eyes. He has to learn to live with his new condition. His friends like Tails and Knuckles are confused and a bit scared. However, Sonic discovers that being a vampire gives him the ability to sense danger from afar. He then uses this to his advantage to protect the town and his friends from an even greater evil that's lurking in the shadows. Eventually, he might find a way to reverse the transformation and return to his normal self.
In a 'Harry turns into a vampire' fanfiction, the story could start with Harry being cursed by a powerful and ancient spell that turns him into a vampire. His friends at Hogwarts are initially scared and unsure how to deal with him. However, Harry is determined to find a way to reverse the transformation. Along the way, he discovers that there are some positive aspects to being a vampire, such as heightened senses that help him in his detective - like investigations into the origin of the curse.
There's often the 'secret origin' trope. Maybe the reader's transformation is part of a bigger prophecy or some long - forgotten vampire ritual. And then there's the 'vampire mentor' trope, where an older, more experienced vampire helps the newly - turned reader navigate their new life, teaching them about hunting, hiding from sunlight, etc.
Well, 'Vampiric Awakening of the Reader' is also a good one. In this fanfic, the reader is transported into a world of vampires and gradually turns into one. The plot is full of twists and turns as they deal with vampire politics and their newfound powers.
