Who are the main characters in Bella Swan Siren Sister fanfiction?

Edward can be really interesting. His relationship with Bella takes on a new dimension when she's a siren. He has to grapple with his love for her while also being cautious of her new powers. Another character could be Jacob. His loyalty to Bella might be tested as she becomes something different, and he might have his own mixed feelings about her siren side.

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.

One of the main characters could be a villainous vampire. This vampire could be after the sisters for some reason, like their unique powers or because they pose a threat to his own plans in the vampire world. Also, Bella's father Charlie could be a significant character. He might start to suspect that something is different about Bella and her sister, and his reactions and attempts to figure out the truth could be an important part of 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 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.

A powerful werewolf could be the main antagonist. In the fanfiction world, werewolves and vampires often have a tense relationship. If Bella's sister does something that angers the werewolves, like stealing from their territory or harming one of them accidentally while doing her criminal deeds, the werewolf pack leader could become the main antagonist, vowing revenge on the sister and by extension, Bella and the Cullens.

Obviously, Bella Swan is one of the main characters. And the Creeper Mates, though it's not clear exactly who they are as individuals yet. They are likely to be a group or species that Bella interacts with in a significant way.

Obviously, Bella Swan is a main character. She is the one in the unwanted bride situation and the story likely revolves around her journey.

Edward Cullen might also be an important character in some aspects. Since Bella was originally in a relationship with him, his reaction to Bella becoming a mate to the Volturi could be an interesting part of the story. There could be scenes of jealousy or attempts to win her back.

The main characters are Bella Swan and Klaus. However, depending on the specific fanfiction, other characters could also be prominent. For example, Jacob might be involved, as he has a history with Bella. He could have strong reactions to Bella's pregnancy by Klaus. Also, characters like Elijah from Klaus's family might make an appearance and add more complexity to the story, perhaps trying to influence Klaus's actions regarding Bella and the unborn child.
