In Twilight fanfiction, Vampire Bella going to school has multiple difficulties. Firstly, her appearance. Even though she tries to blend in, her pale skin and other vampiric features might make her stand out. Secondly, her academic performance. With her new vampire - enhanced mind, she may find it hard to not seem too smart and draw unwanted attention. Thirdly, the relationships. She has to keep her distance from her old human friends in a way that doesn't seem too odd, while also dealing with any new vampire - related relationships that might form at school.
Well, in this fanfiction, Bella might face challenges in hiding her vampire nature at school. For example, she could struggle with controlling her super strength during gym class or her enhanced senses in a crowded cafeteria. Maybe she'll have to deal with other students who are suspicious of her new, more alluring appearance.
It could be another vampire who is jealous of Bella. Maybe this vampire has been at the school for a while and doesn't like the attention Bella is getting. So, they try to create problems for her, like spreading rumors about her or trying to get her into trouble with the school authorities.
One interesting aspect could be how their relationship dynamics change. In the original, Edward was the vampire and Bella was the human, so reversing their roles might lead to a different power dynamic. For example, Bella as a vampire would have more physical strength and speed, which could make her more protective of Edward. Also, Edward as a human might struggle with his mortality compared to Bella's immortality, creating new tensions and storylines in the fanfiction.
One great fanfiction could be where Edward and Bella's relationship is explored more deeply in a different vampire society setting. For example, they might be in a vampire clan that has unique rules about human - vampire relationships.
In such a fanfiction, it could change the entire dynamic of Bella's relationship with the other characters. Maybe she'd be more confident and powerful from the start.
One popular 'Bella is already a vampire' Twilight fanfiction is 'The New Life of Bella Swan'. It takes the concept and explores how Bella's relationships change when she's already a vampire from the start. Another is 'Bella's Vampire Beginnings' which delves into her early days as a vampire, her new powers and how she copes with the vampire lifestyle.
One common theme is the exploration of Bella's transformation into a vampire in more depth. Another is the relationship between Bella and Edward, but often with a new twist. For example, some fanfictions might focus on how they deal with different challenges as vampires together.
A common theme is the 'what - ifs'. What if Bella had chosen Jacob instead? Fanfictions often explore this alternative storyline and how it would affect the vampire - human relations in Forks. It can be really interesting to see how the characters develop in this different scenario.
