For Harry himself, he would have to find a new place to belong. He might form new alliances with students from other houses. This could lead to a more diverse set of friendships and experiences. His magical education could also take a different turn as he might be exposed to different teaching styles and perspectives outside of Gryffindor. And the overall plot of the fanfiction could shift towards his journey of self - discovery outside of his original house.
The dynamics within Gryffindor would be greatly affected. His friends like Ron and Hermione would be confused and sad. The Gryffindor house would lose one of its most iconic members, and there might be a power shift within the house. Other Gryffindors might feel less confident without Harry around.
It would likely have a huge impact. Snape's personality and experiences might have been very different, and his relationships with other characters could have been much more positive.
The story could develop in a way that Harry goes through a period of self - discovery. Without the Gryffindor identity, he has to re - evaluate who he is. He might explore different kinds of magic that Gryffindor house never encouraged. This exploration could lead him to new powers and a new understanding of the wizarding world.
Perhaps he leaves Gryffindor in fanfiction because he is influenced by a new mentor or friend who is from a different house or group. This person might convince him that he can achieve more or be more true to himself outside of Gryffindor. Also, it could be due to a prophecy or a special mission that requires him to distance himself from Gryffindor for a while to protect the house or the entire Hogwarts from a certain threat.
Well, at first Harry would be very suspicious of Draco. But as Draco shows his Gryffindor side, Harry might start to trust him more. They could become reluctant allies, especially when facing a common enemy.
The story may take a turn where Harry becomes a sort of mediator between the houses. Since he has left Gryffindor, he has a different view and can help bridge the gaps between the different groups in Hogwarts. He might also embark on a personal journey of self - discovery outside the framework of Gryffindor values, which could lead to new magical abilities or insights.
After leaving Gryffindor, Harry may embark on a journey of self - discovery. He could travel to different places, learn new magic, and meet new characters outside of the Gryffindor - centric environment. This new path could lead him to discover a new purpose or a new way to fight against the forces of evil that doesn't rely on the Gryffindor identity.
His relationship with Hermione would likely strengthen. She would be intrigued by his newfound heritage and would help him research more about Gryffindor. Ron, on the other hand, might feel a bit of envy at first but would soon get over it and be proud of Harry. With Dumbledore, Harry might have a more equal relationship as he is now the heir of one of the founders. Dumbledore could share more secrets with him. And with the Slytherins, they might view him with more respect or fear as he is the heir of Gryffindor, which could change the dynamic in the whole school.
The relationship between Harry and the Gryffindor house is likely to be strained. Since Gryffindor is the namesake of the house Harry belongs to, this lack of forgiveness could cause a rift among the students. Some might side with Harry, while others might defend Gryffindor's legacy, creating internal conflicts within the house.
The story would change a great deal. In the original, Harry being in Gryffindor meant he was associated with courage and heroism. In Slytherin in fanfiction, he'd be associated with cunning and ambition. The Sorting Hat's decision to put him in Slytherin would likely be due to some different interpretation of his character traits. Maybe it saw his ambition to defeat Voldemort as more of a Slytherin - like quality. This would also change how the teachers view him. Snape, for example, might be less hostile towards him since they are in the same house.
If Harry Potter was a jinchuuriki in a fanfiction, his identity would be more complex. He would not only be a wizard but also a host to a powerful entity. His relationships with others would shift. Some might fear his new power, while others might try to use him. His journey to defeat Voldemort would take on a new dimension as he has to learn to control and use the power of the jinchuuriki. And his battles would be different, with new abilities and tactics that combine wizardry and jinchuuriki powers.
