It also makes Naruto empathetic. Because he has been through so much struggle alone, he can understand the pain and loneliness of others. When he meets people like Gaara, who also had a difficult childhood, he can immediately relate to them. This empathy helps him in forging alliances and bringing people together, which is important for his goal of becoming Hokage and uniting the village.
Naruto becomes more self - reliant. Anko's training often involves solo tasks and challenges. So Naruto learns to rely on his own skills and instincts more, rather than always looking for backup from his friends. For example, he might learn to scout an area alone or set traps without help.
The training could also make Naruto more disciplined. Minato and Kushina were both highly disciplined ninjas. Their training methods would likely instill in Naruto a sense of order and routine. He would learn to manage his time better for training, and also be more meticulous in his study of jutsu. This new - found discipline could help him in all aspects of his ninja life, from mission planning to combat.
The training makes Naruto more confident in his abilities. Jiraiya constantly challenges Naruto and as Naruto overcomes these challenges, he realizes his own strength. He starts to believe in himself more, which is evident in the way he faces stronger opponents without hesitation later on. Also, Jiraiya's teachings about the ninja way and the importance of protecting those you love make Naruto more determined and focused on his goals.
One of the most dangerous challenges is the lack of proper guidance. Without a teacher, he could easily misuse chakra and harm himself. For instance, when he first tries to perform more complex jutsus, he might not know the limits of his body and chakra reserve.
Jiraiya's training in the fanfiction might focus on Naruto's inner strength as well. He could help Naruto better understand and control the Nine - Tails' power. This new - found control would give Naruto a sense of calm and authority. His character would shift from being just a loud - mouthed underdog to a more respected and powerful ninja. Naruto would also learn about loyalty and sacrifice from Jiraiya, which would shape his values.
In some fanfictions, Deidara might give Naruto training on explosive jutsu control. Since Deidara is known for his explosive clay techniques, he could potentially teach Naruto how to better handle and utilize explosive elements in combat.
Kushina's training in the fanfiction might also impact Naruto's mental state. Knowing that his mother is there to train him gives him more confidence. He feels more connected to his family and his Uzumaki heritage. This new - found confidence reflects in his battles, where he is more fearless and decisive.
Well, one possible plot could be that Naruto, having experienced so much growth himself, decides to pass on his unique ninja skills and values to a young Kakashi. He might teach Kakashi some of his signature jutsus like the Rasengan, but also lessons about friendship and never giving up. Naruto could also share his own experiences of dealing with loss and loneliness, which would be really interesting considering Kakashi's own past traumas.
One of the main challenges is time management. The Chunin Exams are approaching fast, and Naruto has a lot to learn. He has to quickly grasp complex ninja techniques that Kakashi is teaching. Another biggie is dealing with his own impatience. Naruto is eager to prove himself and might rush through the training, not fully absorbing the lessons.
Asuma's training might make Naruto more disciplined. Naruto is known for his impulsive nature, but under Asuma's guidance, he could learn to think before acting.
