Well, her training would probably start at a very young age. She would first learn basic ninja skills like stealth and perception. Then, she could be sent on simple missions within the village. As she grows older, she might be trained by her father in some of his signature jutsu. But also, she would be trained by other specialists in areas like medical ninjutsu or genjutsu, depending on her aptitude.
She would likely be trained by some of the village's top ninja. Her father might get Kakashi or Gai to train her in combat skills. They would teach her how to use different ninja weapons and jutsu effectively.
The Third Hokage's training might have introduced Naruto to more advanced jutsus. For example, he could have taught Naruto better control over his chakra, which is crucial for performing ninjutsu. This would allow Naruto to use his Rasengan more effectively and with less strain.
It could be a former Leaf Village ninja who left due to some sort of disagreement. Maybe someone who didn't agree with the village's leadership or its way of training young ninjas.
Well, Naruto would probably become extremely powerful. The First Hokage had some unique abilities like his Wood Style. Naruto could learn a whole new set of skills and jutsus. He might also gain a different perspective on leadership and the history of the Hidden Leaf. It could change the way he approaches battles and his relationships with other villages too.
In a fanfiction where Naruto is trained by the 3rd Hokage, one possible plot could be that Naruto would gain a more traditional and structured form of training. The 3rd Hokage, being a highly experienced and wise ninja, might focus on Naruto's chakra control from the start. This could lead to Naruto mastering basic jutsus more quickly. He might also be taught more about the history and values of the Hidden Leaf village at an earlier stage, which could shape his understanding of being a ninja differently compared to his original self - taught journey.
Naruto's sense of responsibility would grow. The First Hokage was all about building and protecting the village. Under his training, Naruto would understand the true weight of protecting the Hidden Leaf and its people, and this would be reflected in his actions and decisions.
If Naruto was trained by the 3rd Hokage in fanfiction, his character would develop in a more disciplined way. He would likely be more respectful of the ninja traditions and hierarchy in the village. His hot - headedness might be toned down as the 3rd Hokage would instill in him the importance of patience and strategy. Naruto would also become more confident in his abilities, not just because of his new skills, but also because of the support and guidance of the respected Hokage.
Well, it depends on the nature of the missing ninja. If the missing ninja has a vendetta against the Hidden Leaf, they might train Naruto for their own malicious purposes. However, if they see potential in Naruto to bring about change, they could train him to be a better ninja in a more morally ambiguous way. Maybe they teach him stealth techniques that are not part of the normal ninja curriculum in the Leaf Village.
Another possibility could be Sakura. Although she was in love with Sasuke, in some fanfictions, the storylines can be altered. Sakura is a strong and intelligent character, and she could potentially have a daughter with Naruto in a different narrative where their relationship develops in a new way.
One challenge could be mastering difficult jutsus. The Third Hokage might set high standards for Naruto to learn complex techniques, which would be a struggle for him.
She could have the power of the Nine - Tails like her father. Since Naruto has a strong connection with the Nine - Tails, it's possible that this power is passed down to his daughter. Maybe she can control the chakra of the Nine - Tails more easily and use it for powerful jutsu.
