This kind of fanfiction has the potential to explore a lot of uncharted territory within the 'Harry Potter' world.
In some fanfictions, Harry as the Lord of Slytherin could have a complex relationship with the other houses. For example, he has to deal with the suspicions of Gryffindors who don't trust a Slytherin - led Harry. It's a fascinating exploration of loyalty, prejudice and leadership.
Hermione Granger also plays an important role in many of these fanfictions. She might be initially skeptical of Harry's new role in Slytherin but then comes to see the potential for positive change. Her intelligence is often used to help Harry navigate the challenges of being a Slytherin Lord. And then there's Severus Snape. His past connection to Slytherin and his complex relationship with Harry add more layers to the story.
One great 'Harry Potter Lord Slytherin' fanfic is 'The Slytherin Heir's Redemption'. It explores the idea of a Slytherin descendant trying to break free from the dark reputation of the house. Another is 'Slytherin's Secret Alliance' which delves into how Slytherin students form an unexpected alliance with other houses. And 'Lord Slytherin's Legacy' is also quite interesting as it reimagines the backstory of Lord Slytherin in a creative way.
One common theme is the exploration of a different Hogwarts experience for Harry. Since Slytherin has a different reputation than Gryffindor, Harry might face different challenges and prejudices.

One interesting fanfiction could be 'The Slytherin Ascendancy'. In this fic, Slytherin is portrayed as a shrewd political lord who uses his cunning to navigate the wizarding world's complex political landscape. It delves into how he might have used his House values in a more political sense, like networking and strategic planning.
If Harry Potter becomes Lord Slytherin, he might bring about a new era of unity in Hogwarts. Since he has friends from different houses, he could bridge the gap between Slytherin and the other houses. He may introduce new rules or traditions within the Slytherin house that are more inclusive. For example, he could encourage more cooperation in Quidditch matches instead of the cut - throat competition that has been the norm. Also, his magical abilities, which are already quite remarkable, could be enhanced or used in different ways as Lord Slytherin, perhaps leading to new spells or ways of magic being discovered.
Harry could form an alliance with the goblins. Since Slytherin was known for his cunning and business - like acumen, Harry as Lord Slytherin could use this to his advantage. He could negotiate with the goblins for better terms regarding Gringotts and perhaps form an economic alliance that benefits both the wizarding world and the goblins. Also, he might form an alliance with some of the magical creatures. Slytherin had an affinity for snakes, so Harry could use this connection to reach out to other magical creatures, building bridges between humans and non - humans in the wizarding world.
Well, it changes the narrative a great deal. If Slytherin is a political lord, it adds a whole new layer of complexity. For example, it could mean that the Sorting Hat's decision to place students in Slytherin was not just about their traits but also about their potential role in Slytherin's political machine. This could lead to different interpretations of why certain characters were sorted into Slytherin.
