One common theme is the exploration of cultural differences. For example, how different holidays or traditions are shared between the characters. Another theme is the facing of prejudice. Since it's an interracial relationship in the context of the Twilight universe, they often have to deal with the stares and whispers from others.
A sense of identity is often explored. The interracial character may struggle with their identity within the world of Twilight, especially when in a relationship with Edward. And family acceptance or lack thereof is another theme. The families of the characters may have different reactions to the relationship, which adds drama and depth to the fanfiction.
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.
Another theme is self - discovery. As a human, Edward has to figure out who he is without the allure and power of being a vampire. He might question his own values, his place in the world, and what he really wants to do with his life. This often leads to a journey of self - exploration and growth in the fanfiction stories.
Love in a dangerous world is also very common. The contrast between the violent and often immoral mob world and the pure love that might develop between Edward and another character makes for an interesting dynamic. For example, the main character may be initially afraid of Edward's mob ties but then falls in love with him regardless.
Love is a very common theme. Since it's about Bella as Mrs Edward Cullen, the love between them is often explored in depth. Another theme is family, as she becomes part of the Cullen family. And there's also the theme of adjusting to a new life, being a human turned vampire's wife.
One common theme is family. Since she's part of the Cullen family, the stories often explore her relationships with Edward, their parents, and other siblings. Another theme is identity. She has to figure out who she is as a vampire or as a unique individual within the family. For example, in many fanfictions, she struggles with her powers and how they define her.
The theme of redemption also frequently appears. Even if Edward has committed or been involved in criminal acts, there is often a journey towards making things right. This could involve him trying to protect the ones he loves from the consequences of his actions or trying to find a way to atone for his wrongdoings.
Family unity is also a big theme. The Cullen family comes together to support Edward, Bella and the new baby. They all contribute in different ways, like Carlisle with his medical knowledge and Esme with her motherly care, to ensure the well - being of the baby and the family as a whole.
Jealousy is another big theme. His possessive nature makes him easily jealous when other characters get too close to the one he loves. This jealousy then drives a lot of the plot, leading to conflicts and resolutions. In some fanfictions, his jealousy can be quite extreme and lead to some really tense situations.
One common theme is the clash of two different worlds. The magical world of Harry Potter with its spells and wands, and the vampire - centered world of Twilight. Another theme is friendship or alliance. Often, the stories will have Harry and Edward form some sort of bond to face a common danger.
Love is a very common theme. Their intense, otherworldly love is often explored in different ways, like how it endures hardships. For example, in many fanfictions, they face new vampire - related threats but their love stays strong.
