One interesting fanfiction could be about Jacob and Rosalie forming an unlikely alliance to protect the Cullen family from a new threat. They put aside their differences and use their unique abilities to fend off the danger.
Perhaps a plot where Jacob and Rosalie are forced to go on a journey together. During this journey, they face various challenges that test their limits. They might have to rely on each other's unique abilities to survive. For instance, Rosalie's super strength and speed could help in some situations, while Jacob's ability to transform into a wolf gives them an edge in others. Along the way, they develop a friendship that was unthinkable at the start.
Their relationship could start off rocky. Jacob has always had a bit of a temper, and Rosalie is not one to back down easily. But as they interact more, they might find common ground. Maybe it begins with a grudging respect for each other's loyalty to their own kind. As time passes, they could start to see the good in each other beyond their species differences. For example, Jacob might admire Rosalie's fierce protectiveness of her family, and Rosalie could come to appreciate Jacob's straightforwardness.

I really like 'A New Dawn for Jacob and Rosalie' in the world of jacob black and rosalie hale fanfiction. It starts with a very interesting premise where Jacob and Rosalie are forced to work together on a mission that could save their respective clans. As they spend more time together, their relationship evolves in a very engaging way. There's also 'Moonlit Meetings' which is full of intense emotions and great character development for both of them.
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.
Jacob's family might be initially shocked, especially if it was unexpected. But they would likely come around and be supportive. His parents might offer their wisdom on raising a child. Rosalie's family, depending on their nature in the fanfiction, could be either overjoyed or a bit more reserved. If they are more traditional, they might have concerns about the relationship between Jacob and Rosalie.
In Twilight fanfiction, Edward is often depicted as the brooding, vampire hero. He's complex, with his struggle between his love for Bella and his vampire nature. Jacob, on the other hand, is the warm - hearted werewolf. Fanfictions might explore their relationship in different ways. Sometimes they are rivals, fiercely competing for Bella's love. In other stories, they might find a way to coexist or even become friends, despite their natural enmity in the original series.
One common theme is friendship. Often, the OC forms a strong bond with Rosalie. Another theme is self - discovery. The OC might be on a journey to find out who they are, and Rosalie may play a part in that.
