Mainly, it's Carlisle, a sophisticated and noble vampire, and Bella, a character full of curiosity and love. Their relationship is central. But we can't forget about the other vampires in their world. For example, Edward could be an interesting character in this fanfiction. He was once in love with Bella, and his reaction to her being with Carlisle could add a layer of drama. Also, Esme, Carlisle's adoptive mother in a sense, could play a role in either accepting or having some doubts about their union.
The Cullen family members are important characters too. Edward, for example, might have an interesting dynamic with Bella in this fanfiction. He could be either protective or jealous of Carlisle's special relationship with her.
There could be Edward. Even though the focus is on Carlisle and Bella, Edward's presence might still be felt as he was an important part of Bella's life before. His reactions to Carlisle and Bella's relationship could add some drama.
Well, of course, there's Dark Carlisle, who might be a character with a shadowy past and different moral compasses compared to the regular Carlisle. And then there's Bella. She is often portrayed as the one who tries to understand Dark Carlisle, bringing out different sides of him. There could also be other supporting characters from the Twilight universe, like the other members of the Cullen family, who might react differently to Dark Carlisle and Bella's relationship.
In some fanfictions, other members of the Cullen family can also be important secondary characters. For instance, Edward might play a significant role. He could be either a source of conflict, as he has his own feelings for Bella, or a mediator, trying to understand the strange attraction between Carlisle and Bella. Also, Esme, Carlisle's wife in the original story, could be a character that adds more complexity to the situation. Her reaction to Carlisle's feelings for Bella could range from heartbreak to acceptance, depending on how the author writes it.
In this type of fanfiction, a common plot could be Carlisle and Bella exploring different cultures together. Carlisle, with his long life and vast knowledge, could introduce Bella to things she never knew. They might travel to different places, both modern and historical, and encounter various supernatural beings along the way. This would not only strengthen their relationship but also expose Bella to new aspects of the supernatural world that she was only starting to understand before becoming Carlisle's wife.
One common theme is the exploration of a different power dynamic. Since Carlisle is an older and more experienced vampire, when Bella is his wife, it often shows how she adapts to his world. Another theme is the reaction of the other Cullen family members. They have to accept this new relationship which can lead to some interesting family drama.
The main characters are obviously Carlisle and Esme. Carlisle is a kind - hearted vampire with a strong moral compass, often acting as a leader. Esme, on the other hand, is a warm and nurturing vampire. Their personalities play a huge role in how their meeting unfolds in the fanfiction.
In this fanfiction, Carlisle and Edward are the stars. Carlisle, who has a strong sense of right and wrong, and Edward, who can be impulsive at times. Their interactions are bound to be interesting as Carlisle tries to discipline Edward. It's also possible that other members of the Cullen family could be involved, either as bystanders or as characters who influence the situation between Carlisle and Edward.
One common theme is protection. Carlisle often takes on the role of protecting Bella in these fanfictions. Another theme could be the exploration of an unconventional relationship, as their relationship in the original series was not as central as it can be in fanfiction.
It really depends on the specific fanfic. There could be her husband, who would be a central character as well. He might be the one that Bella is trying to be the perfect wife for. There could also be friends or family members. Maybe a nosy neighbor who adds some comedic relief or a mother - in - law who has high expectations of Bella. In some cases, there could be a rival character, someone who is jealous of Bella's relationship or her status as the perfect wife.
