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.
The creation of this new taijutsu in the fanfiction could also lead to new training methods. Senseis in different villages might start to incorporate elements of Naruto's new taijutsu into their training curriculums. This would not only improve the skills of individual ninjas but also potentially raise the overall combat capabilities of the entire ninja community.
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.
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.
His son could impact the ninja world by bringing back some of Hashirama's old ideals. Hashirama was known for his strong belief in peace and unity. The son could revive these values and inspire the new generation of ninjas to strive for a more harmonious world.
It could have a significant impact. For one, it would show a different side of the ninja world, that even ninjas have personal lives and family matters. It might inspire other young ninjas to think about family in the midst of their dangerous careers. The village would probably be more protective of Kurenai, and Naruto's role in her pregnancy story could also boost his reputation as a caring and helpful ninja.
The other ninja villages would also be affected. Naruto was a key figure in maintaining peace and balance among the villages. His death could lead to old rivalries resurfacing. Without Boruto, the future that everyone had envisioned for a more united ninja world would be in jeopardy. Some villages might even see this as an opportunity to expand their territories or influence.
The child might introduce new ninja techniques. Combining the power of the Uzumaki and Hyuga clans, they could develop something truly unique. This new technique could change the way battles are fought in the ninja world. For example, if they can merge the Byakugan's perception abilities with Naruto's chakra control, it could create a whole new level of strategic advantage in combat.
It could change the power dynamics in the ninja world. Naruto has a lot of potential, and with Ino's family support, he might grow even faster. This could make his village, Konoha, stronger. Other villages might view this new Naruto - Ino family connection as a threat or an opportunity for alliance. Also, Naruto could influence Ino's family's standing in the village, perhaps elevating it.
The baby could bring new hope. As Naruto is a respected figure and Hanabi from an important clan, the baby might be seen as a unifying force. It could inspire the next generation of ninjas to strive for greater things.
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.
