Another plot could involve the Potter family. Imagine a fanfiction where Harry's children discover a hidden room in Hogwarts that was used by their father and his friends when they were students. Inside, they find old spells and artifacts that help them solve a mystery related to the school's founding. They might also learn more about their family's past in the process.
One idea could be to focus on the Weasley family. For example, create a story where the younger Weasley siblings start a secret club at Hogwarts to preserve and study the family's magical traditions that are in danger of being forgotten. They could face challenges from other students who think their traditions are old - fashioned.
You could also do a story about a new family coming to Hogwarts. They are related to an old wizarding family but have been living in isolation. The family members are very different from each other. One is a bookworm, one is a troublemaker, and one is very shy. Their interactions with the existing Hogwarts families and students could form an interesting family - school project fanfiction. They could face prejudice at first but then prove themselves through their unique magical abilities.
One possible plot could be that the Royal Family discovers the wizarding world through Harry Potter. Maybe a young royal is a Muggle - born wizard and Harry has to help them adjust to Hogwarts life while also dealing with the media frenzy that ensues when the connection between the Royal Family and the wizarding world is revealed.
One possible plot could be that Harry, after all his adventures, realizes the importance of a new kind of magical education. He decides to build a school that focuses on teaching not only magic but also how to use it for good in the real world. He might gather his old friends and some new allies to help him find a location, design the curriculum, and recruit students from all over the wizarding world.
Well, it could be about a new student at the Neko School in the Harry Potter universe. Maybe this student has to learn how to control their neko abilities while also studying magic like transfiguration and potions. They might face challenges from other students who are jealous of their unique abilities.
One possible plot could be a crossover where the magic from Harry Potter world somehow seeps into the High School DxD universe. For example, the Hogwarts students end up in the DxD world and have to adapt to the different rules regarding devils, angels and fallen angels. They could use their magic to help or hinder the various factions in DxD depending on their motives.
Sure. A lot of fanfiction writers like to explore new ideas by mixing different popular universes. In 'Harry Potter K Project' fanfiction, you could see things like Hogwarts students visiting the world of K Project or vice versa. They might have to face new challenges and make use of both magical and K - related powers. It's really creative and interesting to read.
One idea could be that Mewtwo somehow gets transported to the Harry Potter universe. It could be mistaken for a very powerful magical creature. Harry and his friends could initially be wary of it, but then realize it has no intention of harm and they team up to fight against the dark forces in the wizarding world using Mewtwo's psychic powers.
Another plot could be that Voldemort discovers Powergirl's existence and sees her as a threat. He tries to manipulate the wizarding world against her. But Harry and his friends believe in her and together they work to expose Voldemort's lies and also learn from Powergirl about different ways of fighting evil. Powergirl could introduce new concepts of justice and heroism to the wizarding world.
One possible plot could be that Harry discovers a hidden magical realm in the Pokémon world during one of his adventures. There, he meets Rayquaza. Rayquaza, being a powerful Pokémon, senses the strong magic within Harry. Together, they have to fight against a dark wizard who has found a way to corrupt Pokémon and use them for evil purposes in both the wizarding world and the Pokémon world.
Maybe the Timekeeper is actually a descendant of an ancient wizarding family who was tasked with keeping time in balance. In the fanfiction, Voldemort discovers this and tries to use the Timekeeper's powers to go back in time and prevent his own downfall. The Timekeeper has to fight against Voldemort's minions while also trying to find a way to protect the timelines. Harry and his friends get involved when they notice strange time - related disturbances around the school. They join forces with the Timekeeper to stop Voldemort's evil plan.
In a fanfiction, the Triforce could be split among Harry, Ron and Hermione. Harry gets the Triforce of Courage, Ron the Triforce of Power (which he learns to use in a more responsible way), and Hermione the Triforce of Wisdom. Together, they combine their powers of the Triforce with their magic skills to defeat Voldemort once and for all. The Triforce's power could also be used to reform the wizarding world, bringing more equality and peace.
