I would recommend 'A New Beginning for Bella and Edward'. This fanfic takes their story in a different direction after the events in the original series. It shows how they handle new challenges together and the growth of their love in the face of those difficulties. There are some really beautiful and heart - warming moments in it.
The popularity of Bella Cullen and Edward Cullen fanfiction comes from the fact that fans were so in love with their relationship in the original books. People wanted to explore more of what could have been, or different scenarios for them.
One aspect of Carlisle Cullen x Bella fanfiction could be the exploration of their unique relationship within the Twilight universe. Carlisle is an old and wise vampire, while Bella is a young human. Fanfictions might delve into how Carlisle's self - control and moral code interact with his growing feelings for Bella. It could also show how Bella views Carlisle in a different light compared to Edward, perhaps seeing him more as a father figure or a source of guidance at first, and then developing more complex emotions.
One characteristic is the exploration of Bella's potential. Since she's a baby in these fanfictions, it could be about how her future abilities might start to show early. It might also include elements of how the Cullen family adjusts to having a baby in their midst, like changing their lifestyle or protecting her from the outside world. This type of fanfiction can also be very family - oriented, highlighting the relationships within the Cullen family with baby Bella as a central figure.
I also like 'The Healer's Touch'. In this fanfiction, Carlisle uses his medical skills not just to heal Bella physically but also to help her through some emotional traumas. It's a heart - warming story that shows a side of their relationship that we don't often see in the original series. It's full of tender moments between them.
One common theme is the exploration of their eternal love. Writers often expand on how their love endures through different challenges. Another theme is the power dynamics, especially considering Edward's vampire nature and Bella's human - turned - vampire state in some stories.
I'm not sure exactly as it could be many things. It might involve Naruto characters interacting with Twilight's Cullen family and Bella in a negative or critical way. Maybe it's about Naruto characters getting involved in the drama of the Twilight world and having some sort of conflict with Bella and the Cullens.
One great 'Bella Swan Alice Cullen Fanfiction' is 'The Unforeseen Bond'. It explores a unique friendship between them that goes beyond the typical storylines. Another one is 'Alice's Vision for Bella', which focuses on how Alice's visions play a role in Bella's life in new and interesting ways. There's also 'Bella and Alice: A Different Path' where they take on challenges together that are not part of the original plot.
Esme Cullen, the matriarch of the Cullen family, would surely be part of the story. She would be very nurturing towards Bella during her pregnancy. Jasper Cullen might also be included, perhaps using his power to influence the emotions of those around Bella to keep her calm during the pregnancy. And of course, there could be other minor characters from the Twilight universe popping up in the fanfic.
The theme of protection also often comes up. Carlisle, being the ethical and caring vampire he is, may feel a strong sense of protecting Bella from various threats in the vampire world. Additionally, there can be a theme of self - discovery for Bella. Through her interactions with Carlisle, she might learn more about herself, her values, and her place in this strange new world she's been thrust into.
