One idea could be Harry starting a magical gardening project at Hogwarts. He could be growing all sorts of magical plants and using them for potion - making and to beautify the school grounds. It would be a fun and positive story.
Harry could be part of a story where he organizes a big inter - house tournament at Hogwarts that focuses on skills other than just Quidditch, like magical art, magical music, and advanced spell - casting. This would bring the different houses together in a friendly competition.
One great idea could be stories that explore the further adventures of the characters after the end of the series. For example, how Harry, Hermione, and Ron continue to protect the wizarding world from new threats. It could also involve the next generation learning magic at Hogwarts and facing their own challenges in a way that stays true to the original values of the series.
A good plot idea is that Snape, as a strict but fair teacher, takes Harry under his wing after realizing Harry has a special talent for a particular area of magic that Snape is an expert in. They then go on a journey of discovery, exploring ancient magic texts together and forming an unexpected bond. Also, perhaps Snape and Harry could be the only two who can stop a magical disaster from happening in Hogwarts by combining their unique skills and knowledge.
Some positive fanfiction concepts could be centered around the creation of new spells by the students. Maybe a group of Ravenclaw students collaborate to invent a spell that can help in environmental protection in the magical world. Or fanfiction that focuses on the relationships between different houses, like how Gryffindors and Hufflepuffs work together on a project to improve the Hogwarts gardens. These ideas stay true to the positive and family - friendly nature of the Harry Potter universe.
Another idea is to write a fanfic about the magical creatures of the 'Harry Potter' world from their perspective. Maybe a story about how a hippogriff views the wizarding students who come to visit it, or how a house - elf dreams of a different kind of life while still serving their wizard family.
A story about Harry Potter's first Christmas at Hogwarts. It could be about how he experiences the magic of the holiday in the wizarding world, with the floating candles, delicious feasts, and special presents. It would be a heartwarming story full of the joy of the season.
One idea could be Machamp helping out at a Pokémon daycare. It uses its strength to move heavy things around, like large play structures for the baby Pokémon. And it protects the daycare from any potential threats.
There could be a story where Catwoman discovers a hidden treasure in Gotham that has the power to heal the city. But she has to race against some non - villainous rivals to get to it first. Along the way, she has to use her wits and her acrobatic skills. This kind of story would be exciting and suitable for all ages.
A really cool plot idea could be that they find a lost magical artifact that has the power to change the future of the wizarding world. But it's cursed and they have to figure out how to break the curse. They journey across different magical locations, meet various magical creatures, and use their combined skills to solve the mystery. This kind of adventure - based plot would be exciting and suitable for all audiences.
One idea could be that they find a hidden passage in the broom closet that leads to a secret part of Hogwarts, like an old library or a room full of forgotten magical artifacts. They then have to figure out how to use these artifacts to help them in their fight against Voldemort. Another could be that they get locked in the broom closet by a spell gone wrong, and while they're in there, they find a diary that reveals some long - forgotten secrets about Hogwarts founders.
A family - friendly plot could involve Harry and Edward accidentally swapping powers. So Harry has vampire - like abilities for a while and Edward has some magical powers. This leads to a lot of comical situations as they try to figure out how to use their new - found abilities and also how to swap back. Also, they could be brought together by a prophecy that foretells of a great event that only they can prevent together. This would involve them traveling to different places in both their worlds to find the clues and items needed to stop this event from happening.
