There are quite a few fanfics out there. You could try searching on platforms like Fanfiction.net or Archive of Our Own. Type in keywords like 'Harry Potter', 'abused', 'Slytherin' and browse through the results. Look for ones with high ratings and positive reviews to find a good read on this rather dark theme.
I'm not sure of a specific title, but generally in such fanfics, the abuse Harry faces in Slytherin could be psychological, like being ostracized or bullied verbally. Some might explore how he tries to keep his Gryffindor values while dealing with this difficult situation in a house known for its more cunning nature.
One great fanfiction in this vein is 'The Slytherin Heir' where Harry, having endured abuse, is sorted into Slytherin. It delves into his complex relationships with his housemates and how he overcomes the stigma associated with Slytherin. The story shows his growth and development as he uses his Slytherin cunning to face the challenges in the wizarding world.
There's a fanfic where Harry is the heir of Slytherin and it focuses on his relationship with the Slytherin house. Instead of the usual enmity, he tries to bridge the gap between Gryffindor and Slytherin. I can't recall the exact name, but it's a really good read if you can find it. It shows Harry's growth as a character and how he uses his newfound heritage to bring about change in Hogwarts.
I really liked 'Harry in Slytherin: A New Path'. It explores how Harry's values and actions might be different if he were in Slytherin. He has to deal with the Slytherin house's reputation and the prejudices that come with it. The author does a great job of showing how he might use his intelligence and cunning in a more Slytherin - like way.
There's a fanfic titled 'Snape's Redemption in Harry's Abuse'. This story focuses on how Snape, who has his own complex past with Harry's father, realizes that Harry is a victim of constant abuse. He decides to use his position as a teacher and his skills in potions and magic to keep Harry safe. It delves deep into the relationship between Snape and Harry, exploring themes of forgiveness and second chances.
I've also read 'Green and Red: A Slytherin - Gryffindor Love Story'. Here, Ginny is initially skeptical of Harry being in Slytherin. But as the story progresses, they discover they have more in common than they thought. The fanfic delves into their personal growth, their love for Quidditch which becomes a connection point, and how they overcome the house rivalries to be together.
I really liked a fanfic where the Slytherin descendant is a girl who discovers her heritage and tries to change the perception of Slytherin in Hogwarts. It shows how she uses her Slytherin traits like cunning and resourcefulness in positive ways. She forms alliances with students from all houses and they go on adventures together. It's a really heartwarming story.
One interesting fanfiction could be 'The Heir of Slytherin's Destiny'. It delves deep into how Harry discovers his heritage as Slytherin's heir and how it changes his relationships at Hogwarts. His friends initially have doubts, but as they see Harry struggle to use this new - found knowledge for good, they come around.
I recall a fanfiction titled 'Protecting Hermione: A Slytherin's Duty'. In this story, the Slytherin's protection of Hermione is not just about her as an individual but also about his view of the greater good. He realizes that Hermione's knowledge and abilities are crucial for the wizarding world, and so he takes it upon himself to safeguard her from those who would want to use or harm her for their own purposes.
Sure. A lot of fanfiction writers enjoy twisting the established lore. In these stories, they might re - imagine Harry's abilities and how they could be related to Slytherin's legacy. Maybe he'd have a different connection to snakes or an even deeper understanding of the Dark Arts, but still use it for good. However, these are just creative interpretations and not part of the original canon.
I'm not sure of a specific 'Harry Potter abused Slytherin' fanfiction. Fanfiction can cover a wide range of themes, but this one seems rather unorthodox. However, you can try searching on major fanfiction websites like Fanfiction.net or Archive of Our Own. Just keep in mind that while exploring fanfiction, you may encounter a variety of interpretations of the original series.
