Well, in a Harry Potter sleepover fanfic, they could start with a feast in the Great Hall that includes all their favorite wizarding foods. Then, they might discover a hidden room in Hogwarts that has been forgotten for ages. Inside, they find old spells and artifacts. As the night goes on, they could have a magical pillow fight where the pillows fly around on their own. And at the end, they all fall asleep under a charmed blanket that gives them pleasant dreams of their greatest adventures at Hogwarts.
One idea could be a sleepover in the Gryffindor common room. The characters could play wizarding games like Exploding Snap. Another idea is having a sleepover in the Forbidden Forest (though dangerous but exciting in fanfiction). They could share stories about their adventures and have a midnight feast with all the magical treats like pumpkin pasties and butterbeer.
One interesting idea could be a fanfic that focuses on the Marauders' time at Hogwarts. It could explore their pranks, friendships, and how they came to be the legends that we hear about in the original books. For example, showing how they created the Marauder's Map in more detail.
One interesting idea could be a fanfic where the Marauders attend Hogwarts during modern times. They'd have to deal with things like smartphones and social media while still maintaining their mischievous ways. Another could be a story that focuses on the lives of the house - elves after the events of the books, perhaps exploring their newfound freedom. And a third idea could be a fanfic about a new dark wizard emerging in the wizarding world years after Voldemort's defeat, and how the new generation of Hogwarts students respond.
A great 'Harry Potter fanfic' idea might be a story that delves deeper into the relationship between Snape and Lily. Maybe a fanfic where Snape has a chance to change the past and save Lily in a different way. Another idea is to write a fanfic about the ghosts in Hogwarts and their backstories, like how they died and why they chose to stay at the school. Additionally, a story where the Weasley twins open a magical joke shop in a different country and the challenges they face there would be really interesting.
One interesting idea could be exploring the lives of the minor characters more in - depth. For example, what was Neville Longbottom's life like during the summers at home? Another idea is to create an alternate ending to the series. Maybe Voldemort could have been redeemed instead of defeated. Also, a fanfic could focus on the magical creatures and their own society within the wizarding world.
A cool plot for a 'bleach sleepover' fanfic could involve the characters from different factions in 'bleach' coming together for a sleepover. For example, the Shinigami and the Arrancar. At first, there's tension, but as the night progresses, they start to understand each other better. They could play games like truth or dare, which leads to some really interesting character revelations and unexpected alliances forming. This could also set the stage for future interactions in the 'bleach' universe outside of the sleepover.
One idea could be a story where Harry discovers a magical potion that has a chemical reaction with the magic in his scar, causing strange and new powers to emerge. Another could be a fanfic where Hermione uses her knowledge of chemistry to analyze the properties of magical substances in a new way, like creating a new type of spell - ink that changes color based on the chemical composition of the air around it. Or perhaps a story about a wizard who was a chemist in the Muggle world before coming to Hogwarts and he tries to combine Muggle chemistry with magic to create unique spells.
One idea could be to explore the lives of minor characters in the Harry Potter universe. For example, you could write about the backstory of Neville Longbottom's parents before they were tortured into insanity. Another idea is to create a new magical creature and describe its interaction with the known wizarding world. Maybe a creature that lives in the Forbidden Forest and has a special connection to the trees there.
One interesting idea could be the combination of the magic system in Harry Potter with the nen abilities from Hunter x Hunter. For example, a character might use nen to enhance their existing wizarding spells, making them more powerful or having unique effects. Another idea could be the introduction of nen-based creatures into the Harry Potter universe, which would add a whole new level of danger and mystery.
One interesting idea could be the combination of magic from Harry Potter and the superhuman strength of Saiyans. For example, a character might use Saiyan power - ups like going Super Saiyan while also casting spells. This could lead to really unique battle scenes and power dynamics.
