Archive of Our Own is another great place. It has a very organized system for categorizing fanfictions. You can search for tags related to 'bill' and 'harry' and probably find some stories where bill has a role in raising harry.
Well, in such a fanfiction, Bill might teach Harry about the wizarding world from a different perspective. Maybe he'd introduce Harry to more about the magical creatures he's encountered during his work with Gringotts. He could also pass on some of the Weasley family's unique traditions and values, which would be a contrast to what Harry has experienced at the Dursleys.
I'm not sure specifically which 'bill raises harry fanfiction' is really good. You could try searching on some well - known fanfiction websites like Archive of Our Own. There might be a wide variety of stories related to this concept there.
His character might become more nurturing. Bill is already a brave and capable wizard, but raising Harry would add a new layer of responsibility to him. He'd have to be more patient and understanding, as Harry has his own traumas from his past. He might also become more protective, like a father figure.
At first, it might be a bit awkward as they come from different generations in the wizarding world. But as they spend more time together, they start to understand each other's strengths and weaknesses. Harry admires Bill's knowledge of magic and his courage, while Bill is drawn to Harry's selfless nature.
Yes, there might be. Fanfiction websites are filled with all sorts of creative and unique crossovers. You can try searching on popular fanfiction platforms like Archive of Our Own or FanFiction.net. Just type in 'Maleficent Raises Harry Potter' in their search bars, and if there are any stories with that concept, they should show up.
They could be like brothers. Harry has a strong connection with the Weasley family already, and with Bill and Charlie, it could be a natural extension of that. They might look out for each other and support one another in any difficult situation.
He could start teaching Harry some defensive magic in case the abuser tries to come back. Also, Bill might use his connections to find a healer or a counselor who can help Harry deal with the emotional trauma of the abuse.
They might start as a sort of mentor - mentee relationship. Bill, being more experienced, can guide Harry in the wizarding world. As time passes, they could become like brothers, always having each other's backs.
I highly doubt it's a widely popular fanfiction given its rather strange and specific premise. Most popular fanfictions tend to focus on more common themes like romance, adventure or the characters' growth.
