A possible plot idea is that Fem Harry discovers she has a special magical ability that only Bill can help her control or understand. This could bring them closer as they explore this new aspect of her magic together. Another idea is that there is a prophecy related to their union that either threatens or promises great things for the wizarding world. They then have to figure out how to deal with this prophecy. Also, the fanfic could explore how Fem Harry adjusts to the Weasley family as Bill's mate. There could be some humorous and heartwarming scenes as she tries to fit in with all the chaos and love that the Weasleys are known for.
One interesting plot idea could be the initial awkwardness between them. Since Harry is now female in this fanfic, she might have different insecurities and ways of interacting. For example, she could be hesitant to get close to Bill because of his werewolf - like tendencies. Another plot idea could be how they deal with the wizarding world's reaction. The wizarding community might be shocked or even disapproving of their relationship, so they would have to face a lot of challenges together. Also, perhaps there could be a plot where they have to team up to fight a new dark force in the wizarding world, and their relationship grows stronger through that shared experience.
Perhaps Bill's mate is an Animagus. She turns into a beautiful, rare animal like a phoenix. Bill discovers her secret accidentally and they bond over their love for magic and the secrets it holds. They go on adventures together, with her in her Animagus form sometimes, exploring the hidden corners of the wizarding world.
A more complex plot could involve time - travel. Harry somehow travels back in time and meets a younger Bill Weasley. They initially don't realize they are soul mates but as they interact more, a special connection forms. However, Harry has to be careful not to change the future too much while also exploring this new - found relationship with Bill.
A third plot could be a story set during a big wizarding festival. Ginny and Bill are both involved in the preparations, but things start to go wrong. They must work together to fix the problems and save the festival. During this time, they might also have to deal with family drama as other Weasleys get involved, and through it all, their bond as siblings - in - law (or just as Weasleys) becomes stronger.
One idea could be that fem Harry Potter and Bill Weasley team up to explore an ancient and forgotten part of the wizarding world. They discover new spells and magical creatures along the way and form a strong friendship based on their shared adventures.
One possible fanfiction could be about Bill Weasley meeting his mate during his work at Gringotts. Maybe she is a half - blood witch who comes in to do some business. They lock eyes and there's an instant connection. Bill, with his long hair and cool demeanor, catches her attention right away. And she, with her unique charm, makes Bill forget all about the gold he was counting.
One plot idea could be that Hermione and Bill team up for a dangerous magical research project. They might have to travel to far - off and dangerous places, facing ancient magical creatures and dark magic along the way. Their different areas of expertise - Hermione's vast book knowledge and Bill's hands - on experience with dangerous magical situations - would make for an exciting combination.
Perhaps they start a magical creature protection club together. Fem Harry Potter, with her compassion, and William Weasley, with his family's love for all things magical, recruit students from all houses. They face opposition from some traditionalist teachers who think it's a waste of time, but they persevere and make a real difference in the treatment of magical creatures at Hogwarts.
One common storyline is that of friendship development. Since Harry is female in these fanfictions, there could be a different dynamic in how she and Bill interact compared to the original male - male relationship in the books. Bill might take on a protective older brother - like role towards Fem Harry. Another storyline could be adventure - based, where they team up to fight against dark forces. In some fanfictions, there could also be a romantic sub - plot brewing between them, exploring how their personalities would mesh in a romantic context.
One possible plot idea could be that Harry and Bill discover their soulmate connection during a battle against dark forces. They start to feel an unexplainable bond that gives them an edge in the fight, as they can almost anticipate each other's moves. Another idea is that they find out through a magical object, like an ancient mirror that shows soulmate pairs. This leads to them having to deal with the shock of it, especially considering the age difference and Bill's previous relationships. They then have to navigate how to keep this newfound connection a secret from others in the wizarding world who might not understand.
One interesting plot idea could be Fem Harry learning Itachi's unique jutsu skills. Since Itachi is a highly skilled ninja, he could teach her how to use Sharingan - related techniques, which would give her an edge in the wizarding world. Another idea is that Fem Harry's moral compass gets influenced by Itachi's complex sense of right and wrong. Itachi's past actions in the Naruto universe were often driven by a greater good, and Fem Harry might adopt a similar view in dealing with the threats in the wizarding world, like Voldemort.
