Well, you could write a fanfiction where Shikaku has to deal with a new threat that the regular ninja forces are not prepared for. He could use his intelligence to outwit the enemy. Or perhaps a story about Shikaku mentoring a young and inexperienced ninja, sharing his wisdom and knowledge.
A really interesting plot for 'naruto shikaku fanfiction' could be set during a time of peace in the Naruto world. Shikaku, being bored with the lack of action, decides to embark on a self - discovery journey. Along the way, he meets different characters from different villages and learns about their cultures and ways of life. This could also lead to him having to use his skills in unexpected ways to resolve conflicts that arise during his travels.
One plot idea could be that the female Kyuubi has some kind of connection to the world of FF7. Maybe she holds the key to a powerful materia that both the Naruto world and FF7 world are after. Gaara and female Shikaku could be involved in protecting her as she tries to figure out how to use or hide this power. This would bring in elements of both Naruto's ninja battles and FF7's materia - based magic system.
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.
Inoichi could be a great addition. Since he and Shikaku are comrades, there could be stories about their joint missions or their discussions about the future of the village. And don't forget about Kakashi. His laid - back attitude could contrast well with Shikaku's more serious nature in the fanfiction.
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 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 interesting concept could be the merging of different character personalities from the shikaku universe in the fanfiction. For example, if it's a crossover with another genre, like a fantasy world, seeing how the shikaku characters adapt to magic or new social hierarchies can be really engaging.
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.
