Another theme is secrecy. Since their relationship is not something that would be accepted easily in the Twilight world, they often have to keep it a secret. This can lead to a lot of drama and tension in the fanfiction. There are also themes of self - discovery. As they explore their relationship, they also discover new things about themselves, like their capacity for love and acceptance in ways they didn't expect.
Many Jacob x Edward yaoi fanfictions also deal with themes of sacrifice. They might have to sacrifice their relationships with their respective families or packs/covens for the sake of their relationship with each other. And of course, there's the overarching theme of love. How they fall in love, how they express it, and how they deal with the challenges that come their way because of it are all important aspects in these fanfictions.
One common theme is the exploration of their unlikely friendship or relationship. Given their differences as a werewolf and a vampire in the original story, fanfiction often focuses on how they can overcome these barriers. Another theme is the idea of redemption. They might have to atone for past actions towards each other. For example, if they were rivals before, they now seek to make up for it.
Often, in Lazlo x Edward yaoi fanfiction, there are themes of self - discovery. The characters may be on a journey to understand their feelings for each other, and through that, they learn more about themselves. There could also be themes of overcoming obstacles, perhaps from society or their own personal beliefs, to be together.
Another theme is probably the idea of forbidden love. Depending on the context of the original story, their relationship might be seen as not allowed or frowned upon, which adds an element of tension. For example, if they are in a military - based setting, there could be rules against their relationship. And this can create a lot of interesting plotlines in the fanfiction.
The theme of acceptance is also quite prevalent. In these fanfics, they learn to accept each other's differences, whether it's Jacob's wolf nature and Edward's vampire nature. And often there's a theme of redemption, like one of them trying to make up for past mistakes in their relationship.
One common theme could be the exploration of a forbidden or unexpected relationship. Given that they are from different fictional universes, the fanfiction might play with the idea of how they would interact and fall in love.
Often, there are themes related to forbidden love. Since Jacob and Edward are from different 'sides' in the original narrative, their relationship in fanfic can be seen as something that goes against the norm. In lemon fanfic specifically, this forbidden aspect can add an extra layer of intensity to their romantic or sexual encounters. There might also be themes of self - discovery, as they learn more about themselves through their relationship with each other.
One common theme is rivalry turned friendship. Given their initial animosity in the Twilight series, many fanfictions explore how they might overcome their differences and become friends or even more. Another theme is the protection of Bella. They both care about her deeply in the original story, and in fanfictions, this can lead to situations where they have to work together for her sake.
One common theme is the exploration of a different kind of relationship between Jacob and other male characters. It could be about their emotional bond and how it develops in a way that's different from the original story.
The theme of self - discovery is also present. As they enter into this unexpected relationship, both Edward and Jacob may have to re - evaluate their identities and loyalties. This can be a very interesting aspect of the lemon fanfictions, as it adds depth to their relationship beyond just the physical aspects.
Love triangles are a very common theme. Since Bella is torn between Jacob and Edward in the original story, this often gets explored further in fanfiction.
