One idea could be exploring an alternate universe where the rules of the Future Diaries are different. For example, instead of 12 diaries, there are only 6, but with more powerful abilities. Another idea is to focus on the backstories of the minor characters in the original series. Maybe give them their own diaries and show how they would compete in the survival game.
A cool concept for a 'Future Diary Fanfic' could be a time - travel plot. Have a character go back in time to before the Future Diary game started and try to prevent it from ever happening. This could involve changing the fates of the main characters and seeing how it affects the overall story. You could also write a fanfic where the diaries have a mind of their own and start to rebel against their owners, creating chaos in the game.
One idea could be to explore what would happen if Yuno was a pacifist from the start. Instead of her violent ways, she tries to win the survival game through cooperation and strategy. Another could be a story where the rules of the Future Diaries are changed slightly, like the diaries predicting different time frames or having limited visibility. Also, a fanfiction where the characters are transported to a different world while still having their diaries could be really cool.
One interesting concept could be the unique character development. In fanfics related to Future Diary, characters might be explored in new ways, perhaps showing different sides of their personalities. For example, the relationships between the diary holders could be deepened or altered in creative ways. Another aspect could be the alternate plotlines. Fanfic writers might create scenarios where the events in the original Future Diary change drastically, leading to different outcomes and power dynamics among the characters.
Perhaps the characters from the Future Diary world end up in the Naruto universe. Yuno could form an interesting relationship with Naruto. She might see his strong will and be both intrigued and challenged by it. They could team up to fight common enemies, with Yuno's unpredictable and often violent nature contrasting with Naruto's more positive and forgiving attitude.
One idea could be Naruto becoming a mentor to a new generation of ninja. He could pass on his unique skills and the importance of friendship and hard work.
Maybe in the RWBY Future Fanfic, the characters could explore new kingdoms. They might discover hidden secrets about the origin of Dust and how it can be harnessed in more powerful ways. This could lead to new power-ups for the characters and also introduce new allies and enemies.
One idea could be exploring how the future technology in 2015 from the fanfic affects the daily lives of the characters more deeply. For example, how do the flying cars impact traffic rules and social interactions? Another could be a new character introduced in the fanfic who has a special ability related to the time - travel technology and how that changes the story's dynamic. Maybe this character can manipulate time in a different way than the original characters, leading to new adventures and challenges.
You could write about the next generation of Hogwarts students facing a completely different kind of threat than Voldemort. Maybe an inter - dimensional invasion that requires them to learn magic from other magical cultures. This would involve a lot of world - building and creating new magical species and cultures. It could also show how the old traditions of Hogwarts adapt to this new threat.
Another plot could be that in the future, the boundaries between the real world and Lyoko start to blur. The Lyoko Warriors have to find a way to stop this from causing chaos. They might encounter old enemies in new forms and have to use their past experiences combined with new knowledge to save both worlds.
Well, in such a fanfic, there could be ideas like Chat Noir seeing alternate versions of his friends in the future. Maybe he discovers that Ladybug has a different role or identity in the future timeline.
Maybe Ash's kids could have unique Pokémon partners that are hybrids or have special abilities. For example, a Pikachu that can fly or a Charmander with ice - type moves. This would make their journey really exciting as they explore the potential of these special Pokémon. And they could also meet some of Ash's old friends and rivals along the way, who could offer advice or challenges.
