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.
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.
In some 'Harry Potter Forgotten Heir Fanfiction', the forgotten heir might be the key to solving a long - standing mystery in the wizarding world. For example, they could hold the secret to a powerful dark wizard's downfall or the location of a hidden magical artifact. This often leads to a race between the good and the bad characters in the story, with the heir in the middle, trying to figure out who to trust.
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.
There's a possibility that it could be a new character introduced in the fanfiction. This character might have been orphaned and raised in a muggle family, not knowing their true heritage. But as they start at Hogwarts, strange things start to happen and it's revealed that they are the heir to one of the founders. It could also be an existing character like Neville Longbottom. He has shown great courage and loyalty, and there could be a backstory written where he is actually related to one of the founders through a long - forgotten branch of the family.
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.
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 a new character introduced specifically for the fanfiction. Maybe a young witch or wizard who has been living in seclusion and discovers their heritage as the heir of Le Fay later on.
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.
One possible character is Draco Malfoy. In some fanfictions, he is explored as the Slytherin heir, given his family's pure - blood status and connection to the dark arts. Another could be an original character created by the fanfiction author. This character might be a long - lost descendant of Salazar Slytherin, with a mysterious past and special abilities. Sometimes, even Harry Potter himself is made the Slytherin heir in certain very creative fanfictions, which completely changes the dynamic of the story.
