Who are the most interesting characters in 'Bella Swan is a Siren' fanfiction other than Bella?

Well, obviously Bella Swan is one of the main characters. Her sister, who is a siren, is also a main character. Then there would likely be characters from the Twilight series like Edward Cullen, Jacob Black, etc. as they interact with Bella and her sister.

Alice Cullen can be a very popular character. Since she can see the future, in a 'reborn as bella swan' scenario, her interactions with Bella could be really different. Maybe she tries to guide Bella in a new way based on her visions. Also, Carlisle Cullen is popular. His father - figure role towards Bella might be explored further in these fanfictions.

Edward is still very popular. Since he and Bella are now both vampires, their relationship takes on new aspects that fans like to explore. Another popular character is Alice. Her ability to see the future could be really interesting in a story where Bella is a vampire. She could foresee events that involve Bella and help her avoid danger or make important decisions.

One interesting plotline could be the sister having special powers that she has to hide from the Cullens. Maybe she can communicate with sea creatures and this causes some confusion and mystery in the story.

A common theme might be the reaction of the other Twilight characters to Bella as a siren. Edward, for instance, could be both fascinated and worried about this new side of her. Also, the Volturi might see her as a threat due to her siren abilities. This could lead to conflicts and power struggles within the Twilight universe.

Edward Cullen is often a popular character in these fanfictions. Since he has a close relationship with Bella in the original story, his role can be further explored in relation to Rosalie and Bella's relationship. Another one could be Alice Cullen. Her ability to see the future can add an interesting dynamic, especially when it comes to predicting things that might affect Rosalie and Bella's friendship or any adventures they might go on.

There could be her friends. For example, Alice might be there. Alice could be trying to calm Bella down during her tantrum, using her calm and composed nature to soothe Bella's anger.

Edward would still be a very important character. Since he's Bella's love interest in the original 'Twilight' series, in the fanfiction, he would play a major role in Bella's new vampire life. He might help her adjust to her new powers and the vampire lifestyle.

Well, apart from Bella, there could be a male lead who is the creative director of the 'for him' brand. He could be a strict and demanding professional but also has a soft side. Then there are the makeup artists and hair stylists who are always around Bella during shoots. Also, there could be Bella's agent who is constantly trying to get her the best deals and manage her career. There might be some models from other agencies who are jealous of Bella's rise in the 'for him' modeling world.

Edward Cullen would likely be a main character. His reaction to Bella's situation, whether it's concern for her well - being or struggle with his vampiric instincts around her period blood, could be a major part of the story.
