Well, in a fanfiction, Naruto could be creating a super - sized Rasengan. He might be in a situation where he has to defeat a gigantic monster, so he decides to amp up the power of his Rasengan. He spends days trying to gather enough chakra and figure out how to control such a large amount of it. Also, he could be creating a Rasengan with a different shape. Maybe he accidentally mixes his Rasengan with some other chakra - based element and it takes on a triangular shape. This new - shaped Rasengan could have some unexpected properties, like being able to cut through the toughest of defenses more easily.
A possible plot for a Naruto creates Rasengan fanfiction could be that Naruto is in a time - loop. Every time he tries to create the Rasengan, something goes wrong. At first, he thinks it's just his lack of skill, but then he realizes that there is some sort of external force messing with his chakra. He has to figure out what is causing this time - loop and how to break it while still mastering the Rasengan. He might also encounter versions of himself from different timelines who either help or hinder his progress. This would add an interesting twist to the traditional story of Naruto creating the Rasengan.
One idea could be a story where Naruto discovers a new way to combine the Lightning Release with the Rasengan during a intense battle against a powerful enemy. This new technique could give him an edge and lead to a great victory.
One idea could be Naruto teaching the Fire Rasengan to a new generation of ninjas. He could pass on his unique skills and the story could focus on how the new students struggle to master it. It would show the legacy of Naruto's techniques.
One idea could be a story where Naruto discovers a new way to combine the Rasengan with his Sage Mode. He could use the natural energy to enhance the Rasengan's power and create a more devastating attack. Maybe he teaches this new technique to his friends at the ninja academy to inspire the next generation.
One possible plot twist could be that Naruto's early mastery of the Rasengan catches the attention of Orochimaru much earlier. Orochimaru might see Naruto as a more immediate threat or a potential vessel with even greater potential than before. This could lead to more direct and dangerous attacks on Naruto, forcing him to grow even faster in his combat skills and strategic thinking.
A more complex plot might involve Tayuya being captured by an enemy group and Naruto being the only one who can rescue her. Along the way, Naruto discovers some secrets about Tayuya's past that change his perception of her, and she in turn realizes that Naruto is not just a simple - minded ninja as she initially thought. As they escape from the enemy, they form a bond that is both unexpected and deep.
One idea could be that Hitomi has a special power that Naruto discovers during a mission. They then have to work together to keep this power a secret from the wrong people. Another could be a story where Hitomi is from a different village and Naruto has to convince her that Konoha is a place she can trust. Maybe she has some information about a new threat and Naruto needs to protect her while getting that information.
One plot idea could be Naruto trying to understand Pain's ideology on a deeper level while in the midst of battle. Maybe he discovers some similarities between their motives, like their desire for peace in their own ways. Another could be Naruto getting trapped in one of Pain's jutsu and having to experience Pain's past traumas first - hand, which changes his perspective on him.
A more complex plot could be set in a time when there is a famine in the village. Ayame's ramen shop is struggling to get ingredients. Naruto, being the hero he is, offers to help. They travel to different lands to trade for ramen ingredients. Along the way, they encounter various characters from other villages, some friendly and some hostile. This journey not only strengthens their friendship but also helps to save the ramen shop and feed the village.
Another plot could involve Hancock falling ill in the Naruto world. Naruto, with his strong sense of helping others, tries to find a cure for her. This could lead them on a journey across different ninja villages, where they encounter various characters and learn about each other's cultures. Along the way, a romantic relationship might start to develop between them.
Well, a cool plot could be that there is a mysterious force that links Naruto and Rin across different dimensions. Naruto discovers this connection and tries to find Rin in another dimension. As he does, they both realize that they have a shared destiny to save both their dimensions from a common threat. Maybe it's an ancient evil that was once sealed away but is now breaking free.
