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.
He could start by gathering like - minded individuals. Maybe those who share his ideals of hard work and perseverance, like some of the underdogs he befriended throughout his life in the original Naruto story.
In this fanfiction scenario, Naruto's planet might be filled with lots of natural energy. Since he has a strong connection with nature through his Sage Mode. It could have giant toad - like mountains in honor of Mount Myoboku. And there would be areas dedicated to training, just like the Valley of the End, but on a much larger scale.
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.
One way Naruto could create his own style fanfiction is by drawing from his unique life experiences. His journey from an outcast in the village to a respected ninja gives him a wealth of material. He could write about his training with Jiraiya, the challenges he faced in battles, and his relationships with friends like Sasuke and Sakura. This would give the fanfiction a very personal touch.
In this fanfiction, Naruto might gather those who also feel ostracized. He could build a village based on acceptance and equality. His new village might have unique ninja training methods that focus on individual strengths rather than just traditional clan techniques.
Well, Naruto could achieve creating his own empire through his charisma. He has a lot of friends and allies who would follow him. He could start by uniting the hidden villages under a new banner of peace and cooperation, and from there, gradually expand his influence and territory.
In his fanfiction - created kenjutsu style, Naruto might draw inspiration from the elements. Since he has access to wind chakra, his sword style could involve creating wind - enhanced slashes that can cut through almost anything. He could also use his ability to sense danger and turn it into a pre - emptive sword - blocking technique.
In his fanfiction - created taijutsu, Naruto might also incorporate his experience with the Nine - Tails' chakra. He could develop a form of taijutsu that allows him to momentarily access the Nine - Tails' strength during combat. This could result in him having enhanced speed and power in his strikes, as well as the ability to recover quickly from attacks due to the Nine - Tails' regenerative abilities.
