Well, some might have a concept where Harry Potter himself has a harem of followers or friends who are sort of like 'slaves' in the sense that they are extremely loyal and dedicated to him. It could involve characters like Hermione and Ron being part of this group, and they all work together to face new threats in the wizarding world that J.K. Rowling didn't write about. But this is a very different take on the original story and can be quite controversial as it changes the nature of the relationships in the series.
No. The idea of 'harem slaves' goes against the values of equality and freedom that are prevalent in the Harry Potter series. The original series promotes friendship, respect, and the fight against oppression, and the concept of harem slaves is a perversion of these ideals. So, it is not really appropriate within the fandom.
A 'Slaves of Harry Potter' fanfic could explore a really dark and alternative universe within the Harry Potter world. It might involve themes of power, oppression, and the fight for freedom. However, it's important to note that fanfics can vary greatly in quality and content.
Rather than focusing on this type of fanfic which might not be in line with the values of the original work, you could look into fanfics that expand on the relationships between the main characters in a more positive and respectful way, such as exploring the deep friendship between Harry, Hermione and Ron, or the backstories of other minor characters within the 'Harry Potter' universe.
Perhaps the plot involves a group of enslaved house - elves who decide to fight for their own rights rather than relying on the kindness of wizards. They could form an alliance with some of the human characters who oppose the slave - holding system. This would bring a new perspective to the story, as house - elves are often seen as subservient in the original series. It could also explore the complex relationships between different magical species and how they interact in a world full of inequality.
In most mainstream Harry Potter fanfic, the concept of 'Gryffindor slaves' is not a common or canonical idea. Gryffindor is known for its values of courage, chivalry and fairness, which are quite the opposite of slavery. However, in some very niche or non - traditional fanfics, an author might create a unique and unorthodox scenario where something like this could be part of the plot, but it would be far from the norm.
Another interesting concept could be the reaction of the wizarding world to an evil Harry with a harem. How do his former friends like Ron and Hermione react? Do they try to stop him? And how does the wider wizarding society deal with this new, darker version of Harry who has a group of followers in his harem? It can create a lot of conflict and drama in the fanfiction.
One interesting concept could be the different character dynamics. For example, how the relationships between Harry and the various characters in the harem are developed. It might explore new sides of the original Harry Potter characters that we don't see in the official books.
One interesting concept is alternate timelines. For example, what if Harry had been sorted into Slytherin instead of Gryffindor? It could completely change his relationships and the whole story's dynamic. Another concept is character backstories. Fanfic often delves deeper into the pasts of minor characters, like Neville's family history before he came to Hogwarts. And then there are crossovers, like when characters from Harry Potter meet characters from other fantasy worlds, which can create really unique and exciting scenarios.
There's also 'Magic and Love in the Hogwarts Harem'. This fanfic delves deep into the concept of a reverse harem within the Harry Potter universe. It shows how the characters' personalities play out in these new relationship dynamics, with a focus on the slash aspect which adds an interesting layer to the story.
In Harry Potter fanfic, the idea of using the time - turner in ways not explored in the books is really common. For example, some fanfics have characters using it to repeatedly go back in time to practice spells until they're perfect. Also, the concept of a time - loop, where a character is stuck in a repeating period of time until they figure out how to break it, is quite popular. And then there are fanfics that explore the idea of time travel to different parallel wizarding worlds in different time periods, which is really exciting.
