Another possibility is a student at Hogwarts who has always been in the background. A shy or overlooked character who suddenly discovers that they are the unknown heir. For instance, Neville Longbottom could be an interesting choice. He has shown great courage and growth throughout the series, and if he were revealed as the heir, it would give his character a whole new level of importance.
It could be a previously unknown character, like a distant relative of one of the main families in the Harry Potter series. Maybe a long - lost cousin of the Weasleys or a descendant of one of the founders of Hogwarts that has been living in hiding.
In some 'harry potter unknown heir fanfic', the heir might be an outsider in the wizarding world, not from a well - known pure - blood family. This could create a story where they face discrimination and prejudice from some of the traditional wizarding families. But at the same time, their unique perspective and new - found powers help them to make allies among those who believe in equality and change in the wizarding world.
Harry Potter himself could be a potential candidate. Given his unique connection to Voldemort and his own powerful magic, it's not a stretch to imagine him being the heir of some long - forgotten magic. Another could be Hermione. Her intelligence and thirst for knowledge could be signs that she has a deeper connection to a magical heritage. Ron could also be a candidate, as his family has a long history in the wizarding world and there could be some hidden magic in his bloodline.
It could be a previously unknown student at Hogwarts. Maybe a shy Ravenclaw who has always been good at spells that require great intelligence and wisdom, which are traits often associated with Merlin.
It could be Harry Potter himself. Since he has so many special qualities and a deep connection to Hogwarts, he might be revealed as an heir. Maybe he has some latent powers related to one of the founders that haven't been discovered yet.
Hermione Granger could also be a possible Hogwarts heir. She is extremely intelligent and has a thirst for knowledge about Hogwarts' history and magic. Her Muggle - born status might seem to be a contradiction, but it could also be part of what makes her unique as the heir. She could bring new perspectives and use her vast knowledge to unlock secrets about the heir's role and the future of Hogwarts.
Perhaps it could be a character who was previously thought to be a Muggle - born but actually has a hidden wizarding heritage. In the fanfiction world, they could discover that they are the heir to a powerful wizarding legacy through some strange events or revelations. This would completely change their perception of themselves and their place in the wizarding world.
In the fanfiction world, Harry might be the heir to Hogwarts if there was some sort of magical pact made generations ago. For example, perhaps one of his ancestors had a special role in the creation or protection of Hogwarts, and this role was passed down through the family. It could also be that his unique magical abilities, like his ability to resist Voldemort's attacks from a young age, are signs of a deeper connection to Hogwarts itself. This connection could be what designates him as the heir in the fanfiction's plot.
Neville Longbottom is another possible heir. He has a strong connection to Gryffindor through his family's long - standing association with the house. His growth from a shy and clumsy boy to a brave and powerful wizard could be part of a story where he is the heir of the founders. His ability to stand up to the Death Eaters in the final battle shows his hidden strength, which could be related to the founders' magic.
Well, Harry Potter himself could be a possible heir. He already has so many Gryffindor - like qualities. His courage and loyalty make him a strong candidate.
