Yes, there are likely to be such fanfictions out there. The Harry Potter fandom is vast and diverse, and fans often come up with creative and unexpected scenarios like this. However, the quality and content of these fanfictions can vary greatly.
Definitely. Fanfiction writers love to play with the idea of changing characters' relationships. In a 'Harry Potter is Pansy's twin' fanfiction, we could see how their shared heritage might influence their magical abilities and personalities. Maybe they have some sort of special connection that is different from the relationships in the original books. It could also lead to a rewrite of major events in the Harry Potter story, with their twin bond playing a crucial role.
One of the best is 'The Twin's Bond' which beautifully explores the relationship between the twins in a way that stays true to the spirit of the Harry Potter world. It has great character development and engaging plotlines.
Most probably Fred and George Weasley. They are the iconic twins in the Potterverse. They are known for their pranks and their unique magical inventions. But in this fanfiction, Harry is considered the better one, so they are likely the ones being compared to Harry.
I think this fanfiction might focus on Harry Potter having qualities that make him the 'better twin'. It could be related to his courage. For example, in many situations in the original series, Harry showed extraordinary courage, like facing Voldemort. In this fanfiction, perhaps that courage is contrasted with the twins' more mischievous nature, making Harry seem like the better one.
It could be about a fan - created story where Harry Potter is presented as the smart twin. Maybe it explores how his intelligence sets him apart from others in the wizarding world, like coming up with unique spells or solving mysteries more quickly.
One possible fanfiction could be about the twin's adventures at Durmstrang. Maybe they face unique challenges there, like dealing with the different magical curriculum compared to Hogwarts. They might also have to navigate the more competitive and strict environment of Durmstrang. For example, they could be involved in a magical tournament that Durmstrang is famous for, and their skills and character are put to the test.
The'mirror twin' in this 'harry potter is a mirror twin fanfiction' could hold great significance. Mirror twins are often seen as two halves of a whole. In the context of Harry Potter, it could mean that the twin has a connection to the main character that goes beyond the normal. Maybe they share a special magical bond. This bond could be used to either help or hinder the main character in their quest. It could also be a way to explore different sides of a character. For instance, if Harry had a mirror twin, the twin might represent the parts of Harry that he has suppressed or the darker aspects of his personality. It can also add a layer of complexity to the relationships in the story, as the other characters would have to deal with this new and unexpected element.
The plot could involve the two of them having different magical abilities despite being twins. Harry might inherit more of his mother's protection magic while James could have some other unique power. They could also have different relationships with Sirius, with Sirius perhaps being more protective of both of them. And when they go to Hogwarts, they could have different reactions to the Sorting Hat. James might be sorted into Gryffindor right away, but Harry could be a Hat - stall between Gryffindor and another house, which could create an interesting story arc about his identity and loyalties.
Yes, there are likely fanfictions out there with such a concept. Fanfiction writers often come up with creative and unexpected crossovers, and making Bella Swan Harry Potter's twin is one of those very imaginative ideas. However, the quality and nature of such fanfictions can vary greatly. Some might focus more on the magical aspects of the Potter world combined with Bella's story from Twilight, while others might take a more comical or even angsty approach.
