One popular theme is the challenges they face as new parents. For example, dealing with the baby's special abilities that might be inherited from their vampire - human union. Another theme could be the reactions of their families to the new baby. The Cullens might be excited but also worried about protecting the baby from the outside world.
Some fanfictions might focus on the 'what ifs' in their relationship. What if Edward didn't come back in New Moon? How would Bella's life change? This kind of theme adds a lot of drama and speculation. There are also themes related to the power dynamics between them. Edward has superhuman strength and abilities, while Bella is a human (at least initially). How does this affect their relationship? Is it a source of conflict or a way for them to protect each other?
One popular theme is the exploration of their relationship in different time periods or alternate universes. For example, some fanfictions might imagine them in a modern world with different social norms.
Some of the themes include the transformation of their characters. In a mob fanfiction, Bella might become a stronger, more assertive character having to deal with the mob environment. Edward, on the other hand, may struggle with his dual identity - his love for Bella and his loyalty to the mob. There's also the theme of family, but in a very different sense. Instead of the normal family unit, it's the mob family which has its own set of rules and hierarchies that they have to navigate around while maintaining their relationship.
One common theme is the challenge of growing up quickly. Since they are teens having a baby, they have to take on adult responsibilities much sooner than expected. Another theme is the strength of their relationship. Their love for each other is tested and often deepens as they face the difficulties together.
Self - discovery is also a theme. Renesmee is constantly learning about herself, her powers, and her place in the world. Fanfictions often explore this journey of self - discovery in the context of her family, with Edward and Bella guiding her along the way. This exploration can be really interesting as it shows how she grows and develops not just physically but also in terms of her personality and understanding of the world around her.
One common theme is the family dynamic. Carlisle being the patriarch, his influence on Edward and Bella's relationship within the family framework is often explored. For example, in many fanfictions, he helps them navigate the difficulties of being part of a vampire family.
Some fanfictions might focus on alternative universes. In these stories, Edward and Bella could be in a completely different setting, such as a modern - day city without the presence of vampires and werewolves. But their love still manages to develop in unique ways, which is really interesting for fans who want to see a different take on their relationship.
Some popular themes include their relationship development, like how they deal with the challenges of being in a relationship between a vampire and a human. Another theme could be their adventures together, facing various supernatural threats in the 'Twilight' universe.
Well, 'The Little One's Impact' is also a great one. This fanfiction delves deep into how the baby affects not only Edward and Bella's relationship but also their relationships with the other characters in the Twilight universe. It has some really interesting plot twists that keep you hooked from start to finish.
Another theme is Renesmee's growth and development. Fanfictions often explore how she learns about her powers and her place in the vampire - human - hybrid world. It can be really interesting to see how she matures and how her relationships with her parents and other characters change as she grows. Some fanfictions also focus on her friendships and how she navigates the social aspects of her world.
