Who are some good characters to include in 'harry x twin sister fanfiction' besides Harry and his sister?

Another important character that is often involved is Hagrid. He might be the one who stumbles upon the forgotten twin sister in her hiding place or he could be the one to introduce her to the wizarding world properly. Then there are the Weasley family members. They could play different roles, like Ginny might become the twin sister's best friend or Fred and George could include her in their pranks and adventures, adding some light - heartedness to the story.

Hermione would still be a very popular character. She could be the one to help the twin sister study and understand the more complex aspects of magic. Her logical thinking and vast knowledge of magic would be invaluable in their adventures.

Ron and Hermione are likely to interact with them. Ron might be a bit more protective of the sister, while Hermione would probably study and share knowledge with her. They could all be in the Gryffindor common room, discussing spells and strategies.

Their parents' old friends could be main characters. They might come to check on Harry and his sister, bringing gifts and stories about their parents. These friends could offer guidance and protection when needed.

At first, they might be a bit competitive, especially in their studies at Hogwarts. But then, when they realize that they are stronger together, their relationship deepens. They could have heart - to - heart talks late at night in the Gryffindor common room. Also, if one of them gets into trouble, like the twin sister accidentally breaks a school rule, Harry would cover for her and vice versa. This would build a strong bond of trust between them. And as they face the challenges of the wizarding world together, their relationship evolves into one of unwavering loyalty.

Luna Lovegood is also quite popular in these fanfictions. She and the twin sister could bond over their shared belief in things that others might find strange. They might go on adventures in the Forbidden Forest together, looking for the Crumple - Horned Snorkack. And of course, Ron is always a key character. He could be like a big brother to the twin sister, and they could have a lot of funny moments together, especially when it comes to food at Hogwarts.

Severus Snape is often a prominent character in these fanfictions. His complex relationship with the Potter family could be explored further. He might have a different attitude towards the twin sister, perhaps seeing in her some qualities that remind him of Lily Potter. This could lead to some interesting interactions and plot developments, like him secretly protecting her or teaching her some advanced potions techniques. Dumbledore is also popular. His all - knowing and guiding role can be enhanced in the fanfiction, as he might have special plans for the twin sister in the fight against Voldemort.

Well, obviously Harry Potter is one of the main characters. His twin sister would be another main character. There might also be the usual suspects from the original series like Hermione and Ron, who would likely be involved in the story as friends and comrades to Harry and his sister. Dumbledore would probably also play an important role as he does in the original books, guiding and protecting the young wizards.

Hermione would be a great character to include. She could be like an older sister figure to Harry's little sister, helping her with her studies and giving her advice on how to handle the challenges at Hogwarts.

You can start by giving her a distinct personality. If Harry is brave and impulsive, she could be more cautious and thoughtful. This would create an interesting contrast between them. Also, give her some unique hobbies or interests, like she's really into ancient runes or potion - making. This will make her a more well - rounded character.
