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 discovery of their unique bond. It often involves a moment of realization for both Harry and Aro that they are meant to be mates. Another theme is the clash of their different worlds. Harry comes from the wizarding world and Aro from his own vampire realm, so there are cultural and power differences that create interesting storylines.
One common theme is the exploration of their different personalities coming together. Remus is more reserved and experienced, while Hermione is bold and studious. Another theme is the magical aspect, like how they use magic together. Also, dealing with the challenges of the wizarding world as a couple is often seen.
One common theme is the idea of acceptance. Hermione has to accept the werewolf's nature, and the werewolf has to accept that someone like Hermione could love him. Another theme is the struggle against society's norms. The wizarding world has a lot of prejudice towards werewolves, and their relationship defies that. Also, there's often the theme of transformation, not just the werewolf's physical transformation but also the transformation of their relationship from strangers or acquaintances to mates.
One common theme is the struggle between love and loyalty. Since Bella was initially in love with Edward in the original series, the fanfiction might explore how she deals with her new connection to Aro. Another theme could be power, as Aro is a very powerful vampire in the Twilight universe.
In many fanfictions exploring this pairing, the authors often focus on how Hermione's intelligence might interact with Aro's power and age - old knowledge. For example, she could be intrigued by his vampiric abilities and try to understand them from a scientific or magical perspective. This could lead to a series of adventures and challenges as they navigate their relationship within the combined universe of 'Harry Potter' and 'Twilight'.
One common theme is the idea of redemption. Lucius, being a former Death Eater, might find redemption through his relationship with Hermione. Severus, too, has his own past to reckon with, and Hermione could be a part of that journey towards self - forgiveness. Another theme could be the breaking of social barriers. Hermione, as a Muggle - born, being mates with two prominent pure - blood wizards goes against the traditional wizarding hierarchy. It can also explore themes of love and loyalty, as she has to balance her relationships with both men while staying true to herself.
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.
A common plotline could be them facing prejudice together. Since Lupin is a werewolf, they might have to deal with people's narrow - minded views. Another is Hermione using her intelligence to find a cure for Lupin's lycanthropy. It could also involve them going on adventures to protect the wizarding world and in the process, their relationship deepens.
One common theme is loyalty. The relationship between the characters often emphasizes their loyalty to each other, no matter what challenges they face. For example, they will always stand by each other's side in dangerous situations.
A frequent theme is the exploration of power. Bellatrix is a powerful and feared witch, and Hermione is also very intelligent and magically capable. Their relationship in these fanfictions often involves power struggles, sharing of power, or a combination of both. Also, there's often the theme of transformation. Both characters may change due to their relationship, for example, Bellatrix might become less cruel or Hermione might become more assertive in the face of danger. There's also the idea of secrecy, as they would need to keep their relationship hidden from most of the wizarding community.
