One element would surely be his determination. His taijutsu style might be designed in a way that the more determined he is, the more powerful his strikes become. It could also have elements of his experiences traveling around the ninja world. He could incorporate different fighting techniques he saw during his adventures. For example, some desert - based moves if he was inspired by the Sand Village's style, combined with his own unique spin.
His taijutsu style could include the use of his shadow clones. He could create a series of complex attacks where his clones perform different maneuvers simultaneously. And because of his connection with the Nine - Tails, it could have an element of unpredictability. His attacks could change in power and speed depending on his emotional state, just like how the Nine - Tails' chakra can flare up suddenly.
It would likely have elements of his Uzumaki heritage. Since the Uzumaki are known for their strong life force, his taijutsu could use that to his advantage, like having quick recovery during a fight. Also, it might have some elements of the toads' fighting style, as he has trained with the toads. Maybe some powerful kicks inspired by Gamabunta's stomps.
He could start by observing different existing taijutsu styles. For example, he might study Lee's Strong Fist style. He could then incorporate his own unique abilities, like his chakra control. Maybe he'd add in some acrobatic moves inspired by his agility. He could also combine it with his Rasengan concept, but in a more physical, close - combat form.
His new taijutsu could change the balance of power in battles. If it's a very powerful form of taijutsu, it could give his village an edge in conflicts. Enemies would have to find new ways to counter his moves, which might lead to a shift in military strategies across the ninja world.
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.
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.
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 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.
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.
Naruto's empire might be a hub of innovation. Given his open - mindedness, he would encourage new jutsu development and scientific research. There would be schools not only for ninjas but also for those interested in other fields like medicine, engineering, etc. Also, the architecture could be a blend of all the hidden villages' styles, symbolizing unity.
His friends like Shikamaru and Choji might support him. They know Naruto's true nature and would see the potential in his new village.
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.
