I'm not sure specifically as I haven't read it. But generally, in a fanfic about an OC (original character) sister related to Jasper, it could be about their relationship, adventures they go on together, or how the OC sister impacts Jasper's life in the fan - created universe.
The main characters would be Jasper and his sister. However, depending on the plot, there could be other characters from the original source material that Jasper is from. For instance, if Jasper is from a TV show or a book series, some of his friends or enemies from that show or book might also play important roles in the fanfic. They could interact with Jasper's sister, either helping or hindering her in her journey within the story.
Once upon a time, Bella's twin sister, let's call her Ella, arrived in Forks. Jasper was immediately intrigued by her unique scent and calm demeanor. Ella, on the other hand, was drawn to Jasper's old - world charm. One day, while walking in the forest, they accidentally met. Jasper was hesitant at first, but Ella's warm smile put him at ease. They started to talk, sharing stories about their pasts. Jasper told her about his time as a Confederate soldier, and Ella told him about growing up away from Forks. As time passed, they became closer and closer, their relationship growing into a deep and meaningful bond.
A common theme is self - discovery. The OC often discovers new things about themselves through their interactions with Jasper. For example, they might find out they are braver or more empathetic than they thought.
To develop the OC sister's character, start by giving her unique traits. For example, if she's really into books, she could use her knowledge from reading various genres to assist Shawn. You can also show her growth over time. Maybe at first, she's a bit shy about getting involved in Shawn's cases, but as she gains confidence, she becomes more assertive in her ideas. Another aspect is her relationships. If she has a complicated relationship with her parents, it can add depth to her character.
A possible plot could be that Bella's twin sister has a special power. Jasper is initially skeptical but soon realizes that this power could be useful for the Cullen family. They start to train together, with Jasper teaching her how to control her emotions while she tries to master her power. During this time, they start to have feelings for each other. However, the Cullen family is divided on whether they should fully accept the twin sister into their group. Jasper has to fight for their relationship and for her acceptance within the family.
There's no one definitive version of Jasper's sister in fanfiction. Different authors will create different characters for her. Some may make her a powerful vampire who has been around for a long time and has a lot of knowledge. Others may portray her as a newly - turned vampire still adjusting to her new existence and learning from Jasper about the ways of the vampire world.
One great 'jasper x oc fanfic' is 'Jasper's New Beginning'. It shows a unique relationship between Jasper and an original character. The story is really engaging as it delves into how they meet and how their bond develops over time.
Well, first, you can give them distinct personalities. For Dom's sister, maybe she has that tough, family - loyal trait like Dom. She could be a skilled mechanic too. For Deckard's sister, perhaps she's more of a strategist. You can also think about their relationships with their brothers and how that shapes them. And don't forget their own goals and dreams in the fanfic world.
In many 'Fast and Furious' fanfics, Vince's sister can be a really interesting character. If she's an original character (OC), she can bring a new dynamic to the story. She might have a complex relationship with Vince, perhaps being protective of him or having some family secrets that tie into the 'Fast and Furious' world. For example, she could be involved in the car racing scene in a different way than the main characters, like being a mechanic who secretly modifies cars for the races.
