They would interact with the Weasley family in a way that combines their old - world charm with new - world ideas. For instance, when it comes to family traditions, they would uphold them but also add a new twist. At Christmas, they might introduce a new game from their OC memories that the family has never played before. They would also be more involved in the kids' education, not just at Hogwarts but also teaching them about the wider world, both wizarding and Muggle. This would strengthen their bond with the family as they bring in fresh perspectives and experiences.
One possible plot could be the OC, now as Arthur Weasley, trying to modernize the wizarding world's technology in a more radical way. Since the OC has different perspectives from the original Arthur, they might introduce new ideas like a more efficient postal system using magic and Muggle technology combined. This could lead to some resistance from traditional wizards but also gain support from the younger generation who are more open to change.
No, it's not a very common theme. Fanfiction usually tends to follow more canon - friendly pairings. Hermione is typically associated with Ron or Harry in the main series, and Arthur Weasley is a much older character. This sort of pairing goes against the general age - appropriate and pre - established relationship dynamics in the 'Harry Potter' universe. So, while there might be some out - there fanfictions exploring this, it's not mainstream.
It could imply a rather strange or non - canonical power dynamic in a fan - created story. In fanfiction, authors often explore unusual relationships and scenarios that deviate from the original source material. Maybe it's a story where Arthur Weasley has some form of control or ownership over Hermione in a very specific, fictional context.
The character dynamics can also be a challenge. Hermione is a very headstrong and intelligent character, while Arthur is more laid - back and family - oriented. Writers need to find a way to make their relationship work in a way that doesn't seem forced. They need to explore how their different personalities can complement each other and drive the story forward.
Family is a very common theme. Since Arthur is a family man, many fanfictions explore his relationship with his wife Molly and their children. They might show how he deals with family problems or how he supports his family during difficult times.
Another good one is 'My Life with George Weasley'. This fanfiction focuses on the daily life of an OC who becomes friends with George first and then their relationship gradually develops into something more. It shows how they face different challenges together, both in the wizarding world and in their personal relationship.
I really like 'A New Beginning'. It features an OC who is a healer. This OC becomes friends with Merlin first and through him, gets involved with Arthur. The story focuses on how the OC uses her healing skills to save Camelot during a plague. It's a really heartwarming story that shows the relationship between the OC, Merlin, and Arthur in a very positive light.
As lemon fanfiction is not something we should promote, in normal Arthur Weasley fanfictions, a theme could be his work at the Ministry of Magic. How he tries to balance his job with his family life. Also, his relationship with his wife, Molly Weasley. How they support each other, and their joint efforts in raising their children, which are all positive and family - oriented themes.
One idea could be a time - travel plot where Hermione somehow gets sent back in time and meets a younger Arthur Weasley. They could team up to solve a mystery that is related to the Weasley family's past and the wizarding world at large. This would allow for a lot of exploration of the wizarding world's history and the early days of the Weasley family.
