An interesting plot could be that the OC is a loner who has always felt out of place. Sam imprints on her, and she initially resists the connection because she's not used to being so closely tied to someone. Another plot idea is that the OC is from a different cultural background and has her own beliefs and traditions. When Sam imprints on her, she has to reconcile her own upbringing with this new, intense bond. Also, the OC could be a journalist who is trying to uncover a mystery in the town that the pack is also involved in. Sam imprints on her, and this complicates the situation as he has to protect her while she's trying to get the story.
One plot idea could be that the OC is a new girl in town who is completely unaware of the werewolf world. Sam imprints on her and has to figure out how to introduce her to this new reality without scaring her away. Another could be that the OC is a hunter who initially thinks Sam is a threat but then realizes he's imprinted on her and has to deal with the moral and emotional conflict. A third idea is that the OC has a special power that the pack needs, and Sam's imprinting on her is what brings her into the fold to help the pack against a new threat.
The OC can be developed by giving her a unique backstory. For example, if she has a troubled past, it can shape how she reacts to Sam's imprinting. Her hobbies and interests are also important. If she loves books, it can be a way for her to bond with Sam over shared literary interests. Another aspect is her relationships with other characters in the fanfiction, like her family or friends. These relationships can show different sides of her personality.
Perhaps Hermione is sent to study werewolf magic for some reason, and she meets Sam Uley. Their cultures clash at first, but as they get to know each other, they start to combine their knowledge. For example, Hermione might teach the pack some basic defensive spells, and Sam could show her the secrets of the werewolf's connection to nature. This could lead to a deeper bond between them and a story of mutual respect and cooperation.
A really cool plot might be that Fem Harry Potter accidentally transports herself to Sam Uley's world while trying out a new spell. She discovers that there are some similarities between the magic in her world and the spiritual powers in Sam's world. Sam and his pack initially view her with suspicion, but as she proves herself helpful, they start to accept her. Together, they could embark on a journey to find a way to send Harry back home, all while facing various challenges along the way, like other supernatural creatures who see Harry as an intruder or a source of power.
A great plot could involve the werewolf OC imprinting on a human who is initially afraid of the supernatural world. The story could then focus on how the werewolf tries to win their trust and introduce them to the world of werewolves and vampires in Twilight. For example, the werewolf could show the human how they protect the town from the vampires at night.
One idea could be that Jacob's imprint on Sam's daughter causes a rift in the pack. Some members might not be okay with it due to the loyalty issues between Sam and Jacob. Another plot could be the girl struggling with her own identity while being the center of this supernatural connection. She could be trying to live a normal life but constantly being pulled into the werewolf world.
One interesting plot could be Sam Uley trying to protect Bella from a new threat in Forks that the Cullens are unaware of. Maybe it's a group of nomadic vampires with a vendetta against the Cullens and Bella gets caught in the middle. Sam, with his pack's strength, steps up to keep her safe.
One common theme is the struggle between the normal world of the OC and the supernatural world that Sam is a part of. It often creates interesting conflicts.
There might be a fanfiction where Bella initially resists the imprint. She's used to her own life and the idea of being imprinted on by Sam might be overwhelming. But as the story progresses, she starts to understand the depth of the connection and how it could bring new meaning and protection to her life. The story could explore her internal struggle and the changes in their relationship over time.
Love and loyalty are also prevalent themes. The relationship between Sam and the OC usually involves a deep sense of loyalty, whether it's to each other or to the pack. And of course, there's the romantic love aspect which is a big part of the Twilight universe.
One idea could be that Bella has a unique connection with the pack through the imprint that defies the normal rules. For example, instead of just one wolf imprinting on her, multiple wolves have a shared imprint-like bond that causes them to protect her in extraordinary ways.
