You could also do a fanfiction that focuses on the friendship between a Pokemon and a non - trainer character. For instance, a story about a Pikachu befriending a young child who is afraid of Pokemon at first but then overcomes that fear through their interactions.
One idea could be to explore an alternate universe where Naruto has a different kind of chakra, like a dark chakra that he has to learn to control. This would completely change his journey and relationships. Another could be a story where Naruto's parents didn't die and how that would affect his growth and his relationship with the village. Maybe he wouldn't be as much of an underdog.
Well, in '1984 fanfic', one interesting idea could be exploring different endings. Maybe the main character manages to overthrow the totalitarian regime in a way not shown in the original. Another could be delving deeper into the relationships between characters that were only hinted at in '1984'. For example, the relationship between Winston and Julia could be explored further, like what if they had a chance to start a real family in a post - Big Brother world.
One interesting idea could be about time travel. Maybe in the book, there are concepts like using wormholes to jump through different eras. It's fascinating as it allows for all kinds of stories, like going back to prevent disasters or meet historical figures.
Well, you could write a fanfiction where the Z - fighters have to face an enemy that can nullify their ki powers. They would then have to rely on their physical combat skills and strategic thinking. Also, a story set in an alternate universe where the roles are reversed, like Frieza is the hero and Goku is the villain. Or perhaps a fanfiction that delves into the backstory of minor characters, like Yamcha's early days as a desert bandit and how he really got into martial arts.
A great idea for a One Piece fanfiction novel is to have a story centered around a new pirate crew. They could start from a small island and gradually build their reputation. Maybe they have a unique goal, like finding a lost treasure that was hidden before the Great Pirate Era. Or you could write a fanfiction where a character from the main series, say Zoro, gets lost in a strange sea area filled with new and dangerous sea creatures. His struggle to find his way back to the Straw Hat Pirates while facing these new challenges could make for an exciting story.
Well, you could write a fanfiction where Harry discovers a new, hidden part of Hogwarts that has been sealed away for centuries. This could lead to him finding ancient spells and artifacts that change the course of his fight against Voldemort.

And then there's the idea of a time - travel fanfiction where Harry goes back to the days of the founders of Hogwarts to learn from them directly.
Well, for a Halloween Party Novel, you could have a plot where a group of friends decides to throw a party in an old, haunted mansion. As the night progresses, strange things start to happen.

Or, there could be a story about a Halloween party where a powerful witch shows up and uses the party as a cover to steal the souls of the guests.
