A Christmas fanfic could center around a group of misfit reindeer who are not part of Santa's main sleigh - pulling team. They accidentally find themselves having to deliver presents to a small, forgotten town on Christmas Eve. It could be a story of their adventure, how they learn to work together, and the joy they bring to the town.
One idea could be that an elf accidentally shrinks due to a magic spell gone wrong in Santa's workshop. Maybe he then has to navigate through the now - gigantic toy - making machines to find the antidote. Another could be that a group of elves are shrunk on purpose for a secret mission to retrieve a lost magical item hidden in a tiny corner of the North Pole.
One idea could be exploring the backstory of Jack Skellington's first encounter with Christmas. Maybe he saw a small glimmer of it as a child - like a single Christmas ornament that fell through a portal into Halloween Town. This could have sparked his initial curiosity long before the events of the movie.
Perhaps a story where a lonely baker during Christmas discovers a crate of lemons. He decides to use them to make a new type of Christmas treat. As he bakes, he meets a mysterious stranger who helps him create the perfect lemon - infused Christmas cookies. Through this process, the baker finds new friends and a new sense of purpose during the holiday season.
One idea could be that Naruto and his friends organize a Christmas party in Konoha. They could decorate the village with Christmas lights and ornaments. Another could be a special Christmas mission where they have to deliver presents to all the ninja families in the village. Maybe there's a villain who tries to steal the Christmas spirit, and Naruto has to use his ninja skills to stop him.
For a more elaborate fanfic, the Christmas ball could be held in a place that is between the light and dark realms. Maleficent arrives with an ulterior motive, but Aurora's pure heart makes her question her own intentions. As they interact during the ball, Aurora shows Maleficent the beauty of the Christmas spirit. This makes Maleficent have a change of heart and she decides to use her powers for good, starting with helping Aurora organize a grand event at the ball to bring the two realms closer together.
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.
A great idea for a Hellsing fanfic is to explore the world outside of the Hellsing Organization's main base. What kind of vampires or other supernatural creatures lurk in the far - flung corners of the world? You could also write a fanfic centered around Integra's training as a young girl, how she overcame the challenges and expectations placed on her as the heir of the Hellsing family. This could include her first encounters with the supernatural and how she learned to handle them, which would give a deeper understanding of her character.
You could write an Inception fanfic that focuses on the backstories of the existing characters. For example, explore how Cobb met and trained with his mentor. Or perhaps a story about Arthur's first experience in shared dreaming. It would give more depth to the characters we already know and love from the movie.
One idea could be a Sonic fanfic where Sonic and his friends travel to a parallel universe where the roles are reversed. For example, Eggman is the hero and Sonic is the villain. It would be really cool to see how they handle this new situation.
One interesting idea could be a fanfic that focuses on the backstories of the minor characters in Deltarune. For example, exploring what the lives of the Darkners were like before the events of the game.
