A theme of cultural clash often appears. Hermione comes from the wizarding world of Hogwarts with its own set of values and norms, while Aro is from a different vampire - centric world. Fanfictions may explore how they bridge this cultural gap or how it causes conflicts between them. Also, redemption arcs can be a theme, where either Hermione or Aro has to redeem themselves in the eyes of the other or in the context of the story's plot.
Some fanfictions focus on the theme of discovery. This could be Hermione discovering the vampire world that Aro is part of, or Aro learning about the unique magic in Hermione's world. It adds an element of mystery and adventure to the stories. There are also stories that revolve around the theme of protection, with either Hermione or Aro taking on the role of protector for the other.
Love against all odds is also a prevalent theme. Given their different natures and the fact that they are from different fictional universes, their love (or the development of their relationship) is often depicted as something that has to overcome many obstacles. This can include the disapproval of their respective friends or the challenges of co - existing in a world that doesn't understand their relationship.
One common theme is the exploration of power dynamics. Aro is a very powerful vampire and Bella has her own unique allure and power, so how they interact in terms of power is often explored.
The theme of morality also pops up a lot. Aro's actions in the Twilight series can be seen as morally ambiguous. In fanfiction, authors often question his actions and try to determine if he's truly a villain or if there's more to his character. Some stories might show him struggling with his own sense of right and wrong.
One common theme is power. Aro is a very powerful vampire, and many fanfictions explore how he uses or misuses his power.
Adventure is also quite common. Given Kagome's nature of being involved in many adventures in her original story, in the fanfiction she and Aro could be on all sorts of quests together. They might face challenges that test their bond and make their relationship stronger. For example, they could be searching for a magical artifact and have to rely on each other's skills to succeed.
The theme of redemption also shows up sometimes. Aro, who is often depicted as a rather ruthless character in the original Twilight series, can be shown to be redeemed or changed through his relationship with Bella in fanfiction. It's an interesting way to re - imagine his character and the relationship between them.
One common theme is the struggle against different vampire clans. Since Bella is associated with the Cullens and Aro is from the Volturi, their relationship often has to face the opposition of their respective groups. Another theme is the exploration of the mate bond. It's about how they come to terms with being mates, which is a very strong and almost fated connection in the vampire world.
Power is a common theme. Since they are part of the Volturi, their power dynamics within the coven and between each other often feature. For example, how they use their powers to protect or influence each other.
One common theme is identity. Since Bella is Aro's daughter, she often has to figure out who she really is in relation to her father and the vampire world. For example, in many stories, she has to decide whether to embrace her father's ways or carve out her own path.
One common theme is self - discovery. The reader often discovers new aspects of themselves through their interactions with Aro. For example, they might find out they have hidden strengths or fears.
