One common theme is friendship. Since they come from different backgrounds within the wizarding world, their friendship is an interesting aspect to explore. Another theme is mentorship, as Bill is older and more experienced, he could potentially mentor Harry in some ways.
Fanfiction.net is also a good place. There are many different categories and you can find Bill x Harry fanfiction under the Harry Potter section. However, the quality may vary more compared to AO3, so you might need to do a bit more sifting through the stories.
One popular Bill x Harry fanfiction might be 'The Unlikely Bond'. It explores a unique friendship that turns into something more between them. It delves deep into their characters and how they interact in a different Hogwarts setting, away from the main plot of the original books.
One common theme is loyalty. Since they are mates, loyalty is a big part of their relationship. In many fanfictions, they will stick by each other through thick and thin, no matter what challenges come their way.
I really like 'Bill Weasley and Harry Potter: A New Friendship'. In this story, they meet under unexpected circumstances and form a strong bond. It shows how Bill's calm and wise nature can balance Harry's impulsive side. Then there's 'When Bill Meets Harry', which starts with a chance encounter and then develops into a deep friendship that has a significant impact on both of their lives and the events in the wizarding world.
One common theme could be the challenges they face as a couple in this unique situation. For example, how they deal with the reactions of their friends and family.
There's also 'A Different Kind of Friendship'. In this one, the author takes a creative approach to their relationship. It shows their friendship evolving over time, with both characters learning from each other. It also has some cool sub - plots that add depth to the story.
The unique combination of characters. Harry is the main hero, Bill has his own charm and experience, and Charlie with his love for dragons. Their different personalities and skills make for a great mix in fanfiction.
Sure. There are some. But it really depends on what you're looking for in a fanfiction. If you like action - packed stories, you might find ones where they battle dark forces together. Or if you prefer character - development - centric ones, there could be stories that show how their relationships change and grow over time.
One popular 'harry x bill fanfiction' is 'The Unlikely Bond'. It explores a unique friendship between Harry and Bill that gradually develops into something more complex. Another great one is 'Bill and Harry's Adventure', which takes them on a magical journey full of challenges and self - discovery.
