One common theme is the exploration of their different backgrounds. Rosalie might come from one type of world and Percy from another, and the fanfiction often focuses on how they bridge that gap.
One common theme is the exploration of their different personalities. Percy is often portrayed as adventurous and quick - thinking, while Rosalie might be seen as more reserved or cautious. Their interactions based on these personality traits create interesting dynamics.
A really interesting Rosalie and Percy fanfiction is 'Love in Unlikely Circumstances'. This one delves deep into their personalities and how they overcome differences to fall in love. The descriptions of their emotions are very detailed, making it a very engaging read.
One great Percy and Rosalie fanfiction is 'Percy's Encounter with Rosalie'. It has an interesting plot where Percy, from his own world, stumbles into Rosalie's realm and they have to work together to overcome various challenges. The story does a wonderful job of developing their characters as they interact in this new and strange situation.
One possibility could be that Percy has special abilities inherited from Rosalie. Maybe he has her beauty but also a unique power like being able to charm people with his words. The story could explore how he grows up in a world full of supernatural elements and has to deal with the expectations that come with being Rosalie's son.
For Percy, you could explore his growth in a world outside of his normal demigod realm. Meeting Rosalie could make him more aware of different forms of immortality and power. Maybe he starts to question his own mortality in a different way. For Rosalie, her encounter with Percy could soften her edges a bit. Since Percy is more in touch with his emotions, she could learn from him and become more empathetic towards others, not just her vampire family.
One idea could be a crossover adventure where Percy and Rosalie have to team up to save both the demigod and vampire worlds from a common threat, like an ancient evil that can manipulate both magic and the undead. They could start off as distrustful of each other due to their very different natures, but gradually learn to respect and rely on one another.
It could be a very protective relationship. Rosalie would probably be very protective of Percy, not wanting him to get into any trouble. Percy might look up to Rosalie and try to make her proud.
The allure lies in the fact that we can see different sides of Rosalie and Edward. In fanfiction, we might see a more vulnerable Edward or a more forgiving Rosalie. It gives fans the chance to rewrite their relationship in a way that satisfies their own desires for the characters.
In Rosalie and Bella mates fanfiction, Rosalie's character development could involve her letting go of her past traumas more easily with Bella's presence. She becomes more forgiving and less bitter. Bella's development could be quite complex. She might grow to have a more nuanced view of the vampire world. She could start to question some of the things she once took for granted. Their relationship forces them both to look at themselves and grow in ways they hadn't expected.
