One plot idea could be that Arturia is summoned to the Naruto world during a great battle. Her skills and chivalrous code might shock the shinobi. She could team up with Naruto to fight a common enemy, like a powerful new Akatsuki member with some kind of magic - related power.
A more complex plot might be that there is a rift in time and space that connects the Fate universe and the Naruto universe. Arturia and Naruto are pulled into an alternate dimension where they have to combine their powers to fix the rift. Along the way, they encounter different versions of their friends and enemies from both universes, and they have to figure out who to trust and how to get back home.
Well, you could have an Arturia Pendragon crossover with a post - apocalyptic setting. Imagine her leading a group of survivors, using her combat skills and leadership to help them thrive in a desolate world. Or perhaps a crossover with a magical school setting. Arturia could be a visiting instructor, teaching the students about honor and combat.
A plot idea could be that Naruto discovers a new, ancient form of chakra that has been lost for centuries. He then has to train to master this chakra while also dealing with the political implications within the Hidden Leaf Village. Some elders might be against him exploring this new power for fear of the unknown, but Naruto, being Naruto, is determined to master it for the good of the village.
One idea could be that the events of 9/11 somehow influence the Hidden Leaf Village. For example, they might tighten security and Naruto could be part of a new team in charge of protecting the village from potential outside threats inspired by the real - world event. Another plot could involve characters from Naruto trying to understand the concept of such a large - scale tragedy and how they can prevent similar things in their own world.
One interesting crossover could be a story where Naruto's ninja skills are combined with Arturia's noble leadership and DxD's supernatural elements. For example, they might team up to fight a common enemy that threatens all their worlds. Naruto could use his shadow clone jutsu in creative ways, Arturia could lead with her wisdom and DxD characters could bring in their unique demonic or angelic powers.
One interesting plot idea could be a time - travel story. For example, Naruto is sent back in time to the era of the First Hokage. He could use his knowledge of future jutsu and events to change things for the better in the past. Another idea is a story where Naruto discovers a hidden clan within Konoha that has a unique and powerful Kekkei Genkai. He then has to help this clan gain acceptance in the village. A third idea might be a story where Naruto is turned into a different creature, like a cat or a fox, and has to find a way to turn back while still dealing with the normal threats to the village.
One idea could be that Neji discovers a new hidden power within Naruto that he helps Naruto master. This could lead to them having to face a new, powerful enemy together.
One plot idea could be that Naruto somehow gets transported to the world where Darkrai exists. Darkrai, known for its ability to induce nightmares, might initially be seen as a threat. But Naruto, with his never - give - up attitude, tries to understand Darkrai. Maybe he discovers that Darkrai is being hunted by other powerful Pokémon and Naruto decides to protect it. This could lead to an alliance between Naruto and Darkrai against their common enemies.
You could also write about Naruto's family during a time of peace. How they interact with the other families in the village, and how they pass on the values of the ninja way to the next generation. It could include family outings, training sessions that are more about bonding than combat, and the family's role in maintaining the positive atmosphere in the village.
Maybe in the fanfiction, Cheetara discovers a strange portal and steps through it, only to find herself in the Hidden Leaf Village. There, she meets Naruto and they start training together. Naruto teaches her some ninja techniques, and in return, Cheetara shows him how to better control his speed. They then enter a tournament together, using their combined skills to win.
One idea could be a crossover where Naruto characters get access to special blades with unique powers. For example, Naruto could get a blade that amplifies his chakra and allows him to perform new jutsu. Another could be a story where a hidden blade is discovered in the Naruto world that has the power to either save or destroy it, and the characters have to fight over its possession.
