What are some interesting 'Harry Potter MI6 fanfic' stories?

One interesting 'Harry Potter MI6 fanfiction' could be about Harry joining MI6 after graduating from Hogwarts and using his magic skills for undercover spy work. For example, he might use the invisibility cloak to gather intelligence.

There are 'Harry Potter fanfic fanfic' that focus on time - travel scenarios. Imagine if a character from the later books travels back in time to the first year at Hogwarts. This can create a lot of interesting plot twists as they try to change or preserve the original story line. Also, some fanfic fanfic might center around magical creatures in a way that wasn't fully explored in the original books, like the life of a hippogriff in more detail.

One interesting concept could be the combination of the magical world of Harry Potter with the unique powers of the Akuma no Mi from One Piece. For example, a character might use a Devil Fruit power in a wizarding duel, creating a whole new dynamic of combat. It could also involve characters from Harry Potter having to adapt to the rules and limitations of the Akuma no Mi powers in their own universe.

Some 'Harry Potter and Lily Potter fanfic' might focus on alternate universes. In one such story, Lily could have survived Voldemort's attack. She would then have to raise Harry in a world that is still recovering from the Dark Lord's first rise. This would change a lot of the dynamics in the story. Harry would grow up with his mother's love and protection, and Lily would have to deal with the knowledge that Voldemort could return at any time.

One interesting plot could be a crossover where a character with the Ope Ope no Mi ability enters the Harry Potter world and uses their power to heal some of the serious injuries that occur during the wizarding battles. For example, they could heal Neville Longbottom after his encounter with Nagini. Another plot could involve using the Ope Ope no Mi to create some sort of unique magical items by rearranging matter, which would be a new concept in the Harry Potter universe. Maybe they could create a new type of potion ingredient that has never been seen before.

I'm not really in favor of the 'slaves' concept in fanfic as it can be a bit disturbing and against the positive spirit of the original 'Harry Potter' series. However, some fanfics might explore power dynamics in a more metaphorical way. But overall, the official 'Harry Potter' works focus on friendship, courage and magic, not slavery themes.

One interesting 'Harry Potter breed fanfic' story could be about the breeding of Hippogriffs in a more domesticated setting. Maybe it explores how wizards are trying to train them for various tasks like mail delivery in a different way than using owls.

One interesting 'Harry Potter Siren Fanfic' could be about a siren who uses her charm to influence the events at Hogwarts in a subtle way. Maybe she befriends Harry and tries to guide him through some challenges using her siren - like powers, which are different from magic but still effective.

There might be a fanfic where a MACUSA auror teams up with a Hogwarts student. They could be working together to stop a dark wizard who is causing chaos in both the American and British wizarding worlds. The story could explore how their different magical educations and approaches to magic come into play.

One interesting 'Harry Potter glutton fanfic' could be about Harry discovering a magical kitchen that creates endless amounts of his favorite wizarding treats. He goes on a bit of a food - filled adventure, trying all sorts of new and old magical delicacies.
