The Cullen family usually plays a significant role. Carlisle, with his medical knowledge (even if it's vampire - related in the Twilight context), might be involved in ensuring a safe birth. Alice could be there, perhaps using her gift to foresee any potential problems during the birth. Even the other members of the Cullen family would be around to offer their support in different ways.
While Bella and Edward are the main focus, sometimes the Volturi are mentioned in a more distant sense. Their presence in the overall Twilight world looms over the couple, but on the wedding night in fanfictions, it's more about Bella and Edward's personal and private moments. It's about their love, their dreams, and their new life together as husband and wife.
Obviously, Bella Parker is the central character. Often, her friends from the performing arts world, like her dance classmates or instructors, are also important characters. They might be there to support her, compete with her, or collaborate on various projects.
Well, the main characters are obviously Bella and Edward. Bella is the one who tries to make Edward jealous, usually by getting close to other male characters. Edward is the one who gets jealous because of his deep love for Bella.
Bella's mother or a close female friend could also be main characters. Her mother could share her own experiences of giving birth and offer practical advice. The close female friend could be there to hold Bella's hand, offer comfort, and maybe even crack a few jokes to lighten the mood during the intense moments of the birth.
The baby, of course. Growing up without a mother would be a huge part of the story. The father would also be deeply affected, having to raise the child alone and deal with the grief of losing his partner.
In the fanfic, perhaps Jasper has some special knowledge or connection to Bella's unborn child. Maybe he senses something different about the baby, which makes him take a more active role in the birth. He could be the one to first hold the baby and discover a unique power or trait that the baby has, which then sets off a whole new series of events in the vampire world.
I'm not sure if there is such a specific fanfiction. Fanfiction covers a wide range of ideas, but this combination seems rather unusual. It might exist in the vast realm of fan - created works, but it's not a common or well - known trope that I'm aware of.
The scene was in a quiet barn. Bella lay on a bed of straw. She was surrounded by soft light. As she gave birth, her breathing was heavy. Puppies started to appear, wet and small. She immediately started to care for them.
Once upon a time, Bella, a beautiful and gentle dog, was about to give birth. Her owner had prepared a warm and cozy corner for her. As the time came, Bella started to pant heavily. With every contraction, a tiny puppy emerged. In the end, she gave birth to five adorable puppies, and she licked them clean with love.
The main character is always Bella in this type of fanfiction. However, new characters could be introduced as well. For instance, a blind mentor who has learned to live fully with blindness could be added. This character could guide Bella and help her accept her condition. Or there could be a villain who tries to take advantage of Bella's blindness, which would then lead to a conflict where Bella has to use her wits and other strengths to overcome the villain.
