Fanfiction about Harry in a house other than Gryffindor: What are some interesting plot ideas?

A plot could be that a Gryffindor Animagus accidentally reveals their form during a Quidditch match. This causes chaos as everyone tries to figure out who it is. It also draws the attention of the Ministry of Magic who have strict rules about unregistered Animagi. The character then has to deal with the consequences while also trying to prove they mean no harm.

One plot idea could be that Harry discovers his heritage as the heir of Godric Gryffindor early on. This could lead to him having special powers or abilities that are associated with Gryffindor. For example, he might be able to communicate with the portraits of Gryffindor more easily and gain wisdom from them. Another idea is that there could be a hidden treasure or weapon left by Gryffindor that only his heir can find and use to defeat Voldemort. It could also involve a quest where Harry has to prove his worthiness as the heir by facing various challenges that test his Gryffindorian traits like courage, chivalry, and determination.

One plot idea could be that she struggles with the family expectations of being a Malfoy while having the brave and chivalrous values of Gryffindor. Maybe she has to keep her Gryffindor identity a secret from her family at first. Another could be that she forms an unlikely friendship with a pure - blood supremacist in Slytherin and tries to change their views through her Gryffindor - influenced actions. And she might also be involved in a quest to protect Hogwarts from a dark force, using her unique position of being a Malfoy yet having Gryffindor qualities.

If Harry was in Slytherin, his relationship with Ron would be very different. Ron, with his Gryffindor - Slytherin prejudice, might initially be hostile. But over time, they could come to understand each other better. His relationship with Hermione might also change as she might see him as a project to 'reform' in Slytherin. With Draco, there could be a more complex dynamic as they are in the same house now.

A plot could be the Head of Gryffindor having to deal with a rivalry between Gryffindor and Slytherin that gets out of hand. They would need to find a way to calm the students down and promote unity among the houses.

Another plot could be that Draco's sorting into Gryffindor causes a rift in his family. His parents are disappointed, but Draco finds a new family among his Gryffindor housemates. He could also have a love interest in a Gryffindor girl, and they have to overcome the house rivalries to be together. The story could explore how Draco changes and grows in this new environment.

One idea could be that Regulus Black, despite being a Slytherin in the original story, has a secret admiration for Gryffindor values. So, in the fanfiction, he could start secretly taking part in Gryffindor - like adventures. For example, he might help Gryffindor students in a fight against some dark forces in the Forbidden Forest.

A plot might involve Harry Potter as a house - elf being magically bound to serve Draco Malfoy. This would create a really tense situation as Harry has to resist Draco's cruel orders while still trying to figure out how to break the spell. He could also discover that there are secrets in Malfoy Manor that are related to the Dark Arts and the rise of Voldemort. As he tries to expose these secrets, he uses his wits and the skills he has as Harry Potter, even in his house - elf form, to outsmart the Death Eaters and the Malfoys.

One plot idea could be that the house - elf imparts unique magical knowledge to Harry that he doesn't get at Hogwarts. For example, teaching him ancient spells passed down in the house - elf community. Another could be that the house - elf protects Harry from threats in a very different way than Dumbledore or his friends. Maybe the house - elf uses its own brand of magic, which is more instinctive and less rule - bound.

A plot could revolve around a house - elf who gets accidentally mixed up in a dark wizard's plan. Maybe the dark wizard forces the house - elf to steal important magical artifacts from Hogwarts. But the house - elf, having a good heart, tries to find a way to alert the teachers and students without getting caught. Or, there could be a story about a house - elf who befriends a non - magical creature like a Kneazle and they go on an adventure together, exploring the Forbidden Forest and uncovering secrets that are beneficial to the wizarding world.
