One of the themes is the idea of redemption. In some stories, the love between a werewolf and a vampire can lead one or both of them to change for the better. Also, identity crisis is common. When they fall in love, they may question their loyalty to their own kind and where they truly belong in the world of supernatural beings. It's a complex mix of emotions and loyalties.
The idea of fate also plays a big role. Some fanfictions depict the vampire and werewolf as fated lovers. Despite all the odds against them, they are meant to be together. It gives a sense of inevitability to their relationship. And then there's the theme of discovery. As they get to know each other, they also discover new things about themselves and their own species, which helps them bridge the gap between their two worlds.
One common theme is the struggle against prejudice. Since werewolves and vampires are often depicted as enemies in traditional lore, their love is seen as something that goes against the norm. So they have to fight against the prejudice of their respective communities.
A sense of isolation is another theme. Both vampires and werewolves are often outsiders in human society, and when they fall in love across their species, they become even more isolated. They may face rejection from their own groups and have a hard time finding a place where they can be together. This isolation can lead to a strong bond between the vampire and werewolf in love as they only have each other in a world that doesn't fully accept them.
Well, there's the theme of sacrifice. In many of these fanfictions, either the vampire or the werewolf has to sacrifice something important for the sake of their love. It could be their status in their community, their powers, or even their relationship with their families. Also, the theme of redemption is quite common. For example, a vampire who has been a killer might find redemption through the love of a werewolf. And of course, the power struggle between the two species is always there in the background, adding more drama to the love story.
A sense of the forbidden is also very common. Their relationship goes against the norms of both their werewolf and vampire communities. This adds an element of excitement and danger to the stories. Additionally, themes of self - discovery often come up. As they explore their relationship, they also learn more about themselves and what they truly want in life.
Love and forbidden relationships are very common. Since werewolves and vampires are often portrayed as enemies, their love is seen as taboo. Another theme is power struggles. Both species usually have different levels of power, and fanfictions often explore who is more dominant. Also, identity is a big one. Characters might struggle with their dual nature if they are a half - werewolf, half - vampire for example.
One common theme is the struggle between the human and the wolf nature. The werewolf often has to deal with their animal instincts while in a relationship. Another theme is acceptance. The human lover has to accept the werewolf's true nature. For example, in 'Twilight' with the werewolves, there is a sense of acceptance within the pack.
One common theme is the struggle between two different natures. The vampire has its own set of powers and instincts, like a thirst for blood, and the werewolf has its own, like the change during the full moon. Their relationship often involves dealing with these differences.
Love is a very common theme. Often, a vampire and a werewolf will fall in love, which is against the norms of their respective societies. This creates a lot of conflict and drama.
Mortality and immortality is another common theme. Vampires are immortal while werewolves have a more normal lifespan (in most cases). This creates a contrast and conflict in the relationship. The vampire may have to watch their werewolf lover age and die, or the werewolf may struggle with the vampire's eternal nature. Additionally, themes of loyalty - to their own kind and to their lovers - are often explored in these novels.
