Since it's a fanfiction, the main characters could be entirely new creations that fit within the Harry Potter universe. However, if it sticks to the main theme of the original series, it might still center around the core group of friends. Maybe it focuses on Neville Longbottom and Seamus Finnigan and how they develop a brother - like relationship over the years at Hogwarts. They both grow a lot during their time at school and could be the main characters in this fanfiction, facing challenges together and being 'brothers to the end' in a sense.
It's possible that Dumbledore's portrait or some other form of his presence still has an impact. His wisdom could be guiding Harry and the others through the new challenges in this fanfiction. And characters like Neville Longbottom, who grew to be a strong and important figure in the original series end, might also be involved in the events of this fanfiction.
There could also be other important characters. For instance, Hermione and Ron could play significant roles. They might be initially skeptical about Blaise being Harry's brother but then come to accept and support the new family dynamic. And Dumbledore could also be involved, guiding the two brothers in understanding their new relationship and the implications it has for the wizarding world.
Fanfictions in the Harry Potter world can take on many different themes. 'Brothers to the end' might be centered around the idea of a brotherly bond. In the series, we see the Weasley brothers having a strong connection. This fanfiction could be about a similar relationship, perhaps between some original characters or even a new take on the relationship between existing characters. It could explore how they support each other through the trials at Hogwarts, like dealing with dark magic threats, facing exams, or handling social issues within the school. Their bond could be the main force that drives the story forward, showing how they always have each other's backs, no matter what.
Then there are characters like Dumbledore. In many fanfictions, Dumbledore is often shown to have a deeper knowledge about the Peverell brothers and the Deathly Hallows than he let on in the original books. His wisdom and guidance can play a big role in stories related to the Peverell brothers.
There's no way to tell without reading the fanfic. However, it might feature some of the more popular secondary characters from the Harry Potter books like Luna Lovegood or Draco Malfoy. They could be given a more central role in this fanfic, with the story revolving around their own means and ends.
Well, aside from the three brothers, there might also be other characters that play important roles. For instance, Ginny Weasley could be in the story as Harry's love interest. Mrs. Weasley would also likely be there, fussing over all of them like a mother hen, making sure they're well - fed and taken care of.
In addition to Harry and Ron, there could be other characters like Hermione. She is often part of their adventures in the official Harry Potter series, so in the fanfic, she might play an important role too. Maybe she helps Harry and Ron figure out some mystery related to their new - found 'brother' connection.
Well, clearly Vionery is one of the main characters. Depending on the story, Harry Potter himself might also be a central figure, as he often is in most Hogwarts - related fanfictions. Hermione Granger could also be involved, using her intelligence to assist Vionery in her adventures or studies at Hogwarts.
In harry potter the marauders fanfiction, the main characters are the Marauders themselves. James Potter, the confident and sometimes arrogant Gryffindor. Sirius Black, the black sheep of his pure - blood family. Remus Lupin, the kind - hearted werewolf. And Peter Pettigrew, who was initially part of their tight - knit group. Their interactions, friendships, and later the events that lead to their fates are central to these fanfictions. They are often depicted in their Hogwarts days, full of youth, adventure, and magic.
Harry Potter is the mainstay, as the story is based in the Harry Potter universe. Kurama is the new element that makes it a crossover. In addition, characters like Snape could play significant roles. Snape's complex nature might lead to interesting interactions with Kurama. He could be initially hostile but then come to realize Kurama's value in the fight against the dark side. And of course, Hagrid, with his love for magical creatures, might befriend Kurama and help him adjust to the wizarding world.
