Harry Potter is the central character as the story revolves around his discovery. The Weasleys, of course. Ron Weasley would be a key character as he was Harry's best friend and now becomes his brother. Ginny Weasley also matters a lot, especially if there are any romantic implications in the story. And don't forget Molly Weasley, the mother figure who would be crucial in welcoming Harry into the family and helping him adapt to this new family situation.
Obviously, Harry Potter himself as he is the one finding out this huge truth. And the Weasley family members, especially those like Mr. and Mrs. Weasley who would play important roles in helping Harry understand his new identity.
Well, Harry Potter is the main character as the story revolves around his discovery. Draco Malfoy is crucial as it's a 'Malfoy Romance' story. There could also be new characters introduced that are related to the Malfoy family's secrets. Ginny Weasley might also be in the picture, perhaps being jealous or trying to understand Harry's new connection. And don't forget about Dumbledore, who might have known something all along and could offer some guidance to Harry in this strange new situation.
Maybe Harry discovers he was secretly adopted by the Weasleys all along. So he has to adjust to this new reality and learn about his true family ties within the Weasley clan.
The rest of the Weasley family would also play important roles. Mrs. Weasley would be very involved, as she is always concerned about her children. She would probably be a bit flustered at first but then would do everything she could to make Bill comfortable and ensure a healthy pregnancy. And the other Weasley siblings might offer their own unique forms of support, whether it's through humor or practical help.
Obviously, Harry Potter would be one of the main characters. He is the one who finds the One Ring after all.
Obviously, Paul and Percy are going to be main characters. Paul, as the one who finds out Percy's big secret. Percy, being the demigod whose secret is revealed. And there could also be other characters from the Percy Jackson series like Annabeth. She might be involved in helping Percy deal with Paul's discovery, either by giving advice or by being there to support Percy emotionally.
Well, it depends on the specific fan fiction. Sometimes, Harry finding out he has mates can lead to a polyamorous relationship which is quite different from the traditional relationships in the original Harry Potter series. This can be really interesting as it shows how fan fiction can take the existing characters and put them in unique situations that the original author might not have considered. It can also be a way to explore themes of love, acceptance, and self - discovery for Harry.
Obviously, Harry and Ginny themselves are very popular. Their relationship and how they raise their family is a central focus in many fan fictions. Their children, like James, Albus, and Lily, are also quite popular as they represent the next generation of the Potter - Weasley family. Each of them has their own unique personalities and potential for magical abilities, which makes them interesting characters to explore.
Severus might be initially shocked. He could feel a strange sense of protectiveness over Harry, despite their past differences. He might try to find out who wrote the fan fiction and why they depicted such a disturbing scenario.
In this fan fiction, Harry might initially deny the whole thing. But as he starts to explore this new side of himself, he could discover some hidden secrets about the Malfoy family. This could change his perception of the Malfoys completely. And who knows, it might even lead to a new form of magic or power that he has access to because of his newfound 'Malfoy - ness'.
Ginny is also frequently paired with Harry in such fan fictions. Given their relationship in the original books, it's a natural extension for fan fiction writers. When Harry finds out Ginny is his mate, it often leads to a more intense and magical exploration of their relationship, with added elements of destiny and true love.
