Fanfiction about Harry Potter becoming a Slytherin: What are some interesting plot ideas?

One plot idea could be Harry struggling to fit in at first in Slytherin because of the house's reputation for dark magic, but then he discovers the true values of loyalty and cunning within it. He could form an unlikely friendship with a pure - blood Slytherin who helps him see that not all in Slytherin are bad. Another idea is that Harry uses his newfound Slytherin traits to outwit Voldemort in a different way than in the original story, perhaps by using more stealth and manipulation.

There are various plot ideas. Some fanfictions might explore the idea that the heir of Slytherin is not a single individual but a group of people who have been secretly working to change the reputation of Slytherin house. They could be working against dark wizards within the house who are trying to revive the old ways of pure - blood elitism. Or perhaps the heir has a connection to an ancient magic that is tied to Hogwarts itself, and in order to save the school from a new danger, they must unlock this magic. It could also be a story where the heir is in a love triangle with a Gryffindor and a Hufflepuff, adding a romantic element to the plot while still dealing with the challenges of being the heir of Slytherin.

One idea could be that Harry is sorted into Slytherin instead of Gryffindor. He then has to deal with the prejudices within his own house as well as from other houses. Draco could initially be hostile but then they gradually become friends as they discover they have more in common than they thought, like their ambition and a desire to prove themselves. They could team up to solve a mystery within the Slytherin common room that is linked to the dark history of the house.

One idea could be Harry having to deal with the prejudice from his Gryffindor friends. For example, Ron might be initially very suspicious and distant, which forces Harry to prove that he's still the same person. Another plot could involve Harry using Slytherin's more cunning and ambitious traits to fight Voldemort in a different way than in the original story. He might form alliances within Slytherin that were previously unthinkable.

Well, perhaps in the fanfiction, Harry becoming a werewolf leads to a rift between him and some of his friends who are afraid of him now. But then he meets other werewolves who teach him how to control his transformation and he uses this newfound control to his advantage in the fight against the dark forces. He could also form an alliance with the werewolves in the wizarding world, which changes the power dynamics.

Well, a plot could be that Ginny is a Slytherin spy within Gryffindor. She's secretly feeding information to Slytherin about Gryffindor's plans in Quidditch or other competitions. But as she does this, she starts to feel conflicted because she really likes her Gryffindor friends.

Well, Harry could be involved in a story where he tries to change the perception of Slytherin in the wizarding world. Since he is a well - known figure, his presence in Slytherin could be a catalyst for change. He might start a club or organization within Slytherin that promotes equality and friendship among all houses. And perhaps he has to face some challenges from the outside world too, like the Ministry of Magic being skeptical of his motives for being in Slytherin. Harry would then have to prove that his new Slytherin identity doesn't mean he has changed for the worse.

In some fanfictions, a great plot twist is that the 'Prince of Slytherin' is not who everyone thinks he is. He might be under a powerful charm or disguise. And when the real identity is revealed, it turns out to be someone who has been working undercover for Dumbledore all along, which shocks both the characters in the story and the readers.

One interesting plot could be Harry struggling to fit in with the Slytherin ideals at first. He might be constantly at odds with some of the more traditional Slytherin values like pure - blood supremacy. But then he could gradually change the house from within, making his Slytherin peers see that not all Gryffindor traits are bad and vice versa.

Some fanfics have the idea that the Slytherin portraits are actually portals to different times or places related to Slytherin's history. So a student could step through a portrait and end up in a secret Slytherin chamber from centuries ago. Also, there are stories where the portraits can change their appearance based on the current events in the Slytherin house, like if there's a big celebration or a time of crisis.
