Well, in fanfiction, Rosalie and Emmett's daughter could have a very different personality from her parents. Maybe she's more of a peacemaker compared to Rosalie's sometimes fiery nature. She might befriend humans more easily, which could cause some tension within the vampire family as they try to keep their existence a secret. It could also lead to her having her own set of adventures, like trying to find a way to co - exist with humans without breaking the vampire laws.
A characteristic is the exploration of their emotional connection. Since they are both vampires, they have a unique bond. Fanfictions might explore how they deal with their immortality together. Some stories also focus on Rosalie's past traumas and how Emmett helps her heal. They often have a lot of romantic and passionate moments, which are a big draw for readers.
One possibility could be that their daughter has special powers. In the Twilight universe, it's not unheard of. Maybe she has a unique ability to control the elements, which sets her apart from other vampires. This could lead to a whole new set of adventures and challenges for her as she tries to keep her powers a secret from the human world while also dealing with vampire politics.
In Twilight fanfiction, the fact that they are so in love despite their long existence as vampires is fascinating. They have been together for a long time, yet their love seems to be as strong as ever. Their relationship is also interesting because they are part of the Cullen family, and how they interact with the other family members in different situations in fanfiction can be really interesting. For example, when there are family meetings or when they are dealing with a family crisis together.
Well, 'The Rosalie - Emmett Bond' is a really interesting fanfiction. It shows how their relationship evolved from the very beginning. In this story, you can see how they first met and how their bond grew stronger over time. Then there's 'Rosalie's Secret and Emmett's Support'. This one reveals a secret that Rosalie has been hiding and how Emmett stands by her side through it all. Also, 'Emmett and Rosalie's Adventure' is a fun read where they go on an adventure together, which is something not really explored in the original series.
One common trait is beauty. Since both Rosalie and Emmett are good - looking, their daughter is usually described as extremely beautiful, with the typical vampire allure. Another trait could be loyalty. She is often very loyal to her family, just like her parents. For example, she would stand by them in any conflict.
Well, 'Emmett's Devotion to Rosalie' is a fanfiction that really showcases Emmett's unwavering love for Rosalie. It shows how he stands by her no matter what. 'Rosalie and Emmett: In the Shadows of Forks' is another good one. It explores their relationship within the context of the Forks setting. And 'Emmett, Rosalie and the Eternal Love' which emphasizes the idea of their love being eternal and how they overcome various obstacles to stay together.
The twin could create jealousy in Rosalie if Emmett shows too much interest in the new character. Since Rosalie is very protective of her relationship with Emmett, any threat, even if it's just a perceived one from her twin, could cause a rift between her and Emmett. On the other hand, it could also strengthen their bond if they work through it together.
One popular plotline is exploring their backstories more in - depth. For example, how they adjusted to their new vampire lives together. Another could be them facing a new threat in the Twilight universe that specifically targets their relationship. And some fanfictions might focus on their romantic moments, like a special anniversary or a time when they reaffirm their love for each other in a unique way.
One interesting plotline could be Emmett and Rosalie going on a secret adventure away from the Cullen family. This would test their relationship and show their independent sides. Another could be a story where they face a new vampire threat together and their love strengthens as they fight side by side. Or perhaps a plot where they have to deal with a human who discovers their secret and they have to figure out how to protect themselves and the human without breaking the vampire laws.
