The main character is usually the heir themselves. They could be an original character created for the fanfiction or a well - known character from the original series given a new twist. There are also often mentors from each of the houses the heir is related to. For example, a wise old Ravenclaw professor or a brave Gryffindor knight - like figure.
Typically, you'll see the heir, who is often a young wizard or witch. Then there are the friends and allies they gather along the way. Some might be from the houses they are heir to, like a Slytherin who helps them understand the more secretive side of their inheritance. There could also be antagonists, perhaps jealous students or even dark wizards who want to use the heir's power for their own evil purposes. The characters are often complex, with different motives based on their house loyalties or lack thereof.
The main character, the heir, is central. They might be a bit of an outcast at first, not fully fitting into any one house. Then there are the house heads or representatives who play important roles. For example, a Hufflepuff representative might teach the heir about the values of hard work and loyalty in relation to their inheritance. And of course, there are classmates, some of whom might be suspicious or curious about the heir's multiple - house status. These characters interact in various ways, creating drama and plot development within the fanfiction.
One interesting plotline could be the protagonist using the knowledge and resources from multiple houses to solve mysteries that stump others. For example, they might combine Gryffindor's courage with Ravenclaw's wisdom to outwit dark wizards. Another could be the social implications of being an heir of multiple houses, facing both envy and admiration from fellow students.
Hermione could be a main character. She might help Harry understand the implications of being heir to multiple houses. Ron could also be important as he stands by Harry through all the new revelations. There could also be characters like Draco Malfoy. If Harry is heir to Slytherin, Draco's attitude towards Harry might change significantly, adding an interesting dynamic to their relationship.
Maybe a jealous student or a group of students who feel threatened by Harry's new - found status. They could be from pure - blood families who think Harry doesn't deserve to be the heir of so many houses. They might start spreading rumors and causing trouble for Harry at Hogwarts, and eventually, their actions could lead to more dangerous situations as they side with darker forces out of envy.
Well, of course, Harry Potter himself is a common character as the heir in these fanfictions. Hermione is often there too, helping Harry figure out the implications of his new status. Ron may also be present, providing support and some comic relief. Sometimes, characters like Dumbledore play a key role as well, guiding Harry through the revelations about his heritage.
Dumbledore might also be a common character. He could serve as a guide or mentor to Harry in his new role as heir, providing wisdom and advice. Additionally, some fanfictions might include characters from the Potter family's past, like his parents James and Lily, who could appear in flashbacks or as some sort of spiritual guidance for Harry.
Well, it could be about Harry discovering he has some sort of ancient blood connection to multiple houses. Maybe he finds out that his family tree has been misread all along. For example, he could be related to the founders of Hufflepuff and Ravenclaw in some way. This could lead to him having special powers or abilities related to those houses, like being able to access their long - forgotten knowledge or having an affinity for Hufflepuff's loyalty - based magic.
Hermione Granger would also be a great candidate. She is highly intelligent like a Ravenclaw, but her loyalty to her friends and the fight against evil shows Hufflepuff traits. Her courage in the face of danger is Gryffindor - like, and she has proven to be cunning when outwitting her enemies, which is a Slytherin quality.
McGonagall as the Head of Gryffindor is often very popular. She's strict but fair and her powerful magic and no - nonsense attitude make for great stories. Fans like to write about her making tough decisions for the good of Gryffindor and Hogwarts as a whole.
One possible plotline could be Harry discovering the responsibilities that come with being heir to multiple houses. For example, he might have to deal with different magical legacies and political implications within the wizarding world. Another could be how he balances the loyalties to these various houses while still remaining true to his friends at Hogwarts. Maybe he uncovers secrets about the founders of the houses that were long forgotten.
The heir themselves would be a main character, of course. And Harry Potter might still play a role, either as a friend or a rival to the heir. Dumbledore could also be a major character, guiding or observing the heir's journey.
