One possible powerful jutsu he could create is a time - freezing jutsu. This would allow Naruto to stop his opponents in their tracks, giving him the opportunity to either land a decisive blow or set up a more complex strategy. Since Naruto has always been about speed and surprise, this jutsu would add another dimension to his combat style.
If Naruto creates a very powerful and dangerous jutsu, some characters might be afraid of him. For example, the villagers who were once suspicious of his Nine - Tails power could again start to fear him. However, his close friends like Sasuke and Sakura would likely trust him and help him control and master the new jutsu.
In fanfic, Naruto may create his own jutsu based on his emotions. His strong will and never - give - up attitude can be translated into chakra - based techniques. For instance, when he's feeling extremely protective of someone, he channels that emotion into his chakra and creates a defensive jutsu. He also might draw inspiration from his memories. Remembering his training sessions with Jiraiya, he could take some of the basic techniques he learned and add his own twist to them, like adding a wind - element boost to a simple physical attack jutsu.
Well, Naruto could start by gathering like - minded people. Maybe those who also felt left out or had a special bond with him. He could use his skills and charisma to attract them. For example, he could find others who were also orphans or had unique powers like his. Then, he would need to establish a set of rules and values for the clan, something that would be based on his own beliefs such as loyalty, hard work, and never giving up.
One key factor is his vast combat experience. After facing various enemies, he knows the weaknesses and strengths of different jutsus, which helps him create his own. Another factor is his ability to learn from others. He has trained with many great ninjas like Kakashi and Jiraiya, and he can pick up on their techniques and make them his own. Also, his strong bond with the Nine - Tails gives him access to a large amount of chakra and unique chakra properties that he can use in creating new jutsus.
A 'Solar - Flare Rasengan'. Naruto could combine his wind - style chakra with some kind of solar - based energy he discovers. This jutsu would be like a super - charged Rasengan that emits a blinding light as well as powerful wind - based damage.
He could practice in secret locations where no one can see him. For example, in an abandoned cave or a hidden part of the forest. That way, no one will know about the new jutsu he's developing.
One idea could be that Naruto creates his own village as a place of true peace and equality. He invites all those who have been marginalized or ostracized from other villages to join. His village would have unique training methods that combine all the ninja arts he has learned from different places, like the shadow clone jutsu combined with Sand Village's puppet techniques for a new form of combat.
One idea could be that Naruto creates his sword using his chakra. He might infuse it with the power of his Nine - Tails chakra, making the sword have a unique orange glow. This sword could have the ability to cut through any jutsu, like a hot knife through butter.
To write a Naruto creates jutsu fanfiction, consider his growth as a ninja. He has learned from many mentors. In this fanfiction, he could combine the teachings of Jiraiya, Kakashi, and even the Sage of Six Paths to create a unique jutsu. For instance, he might create a jutsu that uses the Rasengan's shape - manipulation along with some of the Sage Mode's power - up. Also, don't forget the emotional aspect. Maybe he creates the jutsu in memory of a fallen comrade, giving it more significance and power.
