Anko might develop a softer side through her interactions with Naruto. She has a tough exterior due to her past, but Naruto's unwavering optimism and kindness could start to break down her walls. She could become more open and trusting towards others in general.
Naruto could also help Anko come to terms with her past association with Orochimaru. His own experiences with forgiving and understanding those who have done wrong, like Gaara, could be a guiding light for Anko. This could lead to her finally being able to move on from that dark part of her life and focus more on her future and her relationship with Naruto and the rest of the village.
For Neji, he could develop more of an emotional side. In the original series, he was often stoic. In fanfiction, he might open up more, especially to Tenten. Maybe he starts to show his sense of humor or his fears. For Tenten, she could become more confident in her abilities. She's always been a strong fighter, but she might gain the confidence to take on more leadership roles within their team.
Well, one possibility could be the rebuilding of the ninja villages. After the war, there would be a lot of destruction to repair. Maybe Naruto and his friends would take on leadership roles in this rebuilding process.
For Naruto, he could develop more understanding of the darker side of the ninja world through his interactions with Tayuya. Tayuya, on the other hand, might start to see the value of friendship and loyalty like Naruto has. For example, Naruto's unwavering belief in his friends could rub off on Tayuya, making her question her previous solitary and somewhat ruthless ways.
Another idea is a story where Anko discovers a new power within Naruto that no one else has noticed. This could lead to her taking Naruto under her wing in a more personal training session, different from the ones he has had with Kakashi or Jiraiya. It could be a story of Anko helping Naruto unlock this hidden potential while also dealing with her own past traumas related to Orochimaru.
For Naruto, he might become more settled and focused on building a family life. He's used to being the wild, go - getting hero, but with Tenten, he learns the value of a quiet home life. Tenten, on the other hand, could become more confident in her role as a partner to Naruto. She may also develop more diplomatic skills as she has to deal with Naruto's high - profile status in the village.
Naruto could develop a deeper sense of protectiveness. He has protected the village many times, but now his focus is on protecting Mei and the baby. This could lead to him learning new jutsu specifically for their safety. Mei might experience a change in her leadership style. She may start to see the importance of family values in the Mist Village and try to incorporate that into her rule. As she goes through the pregnancy, she could also become more empathetic towards the women in her village who are also mothers or expecting mothers.
Naruto would likely become more solemn and responsible. He's no longer just a ninja protecting his village but a being in charge of an entire universe. His view on life and death would change drastically. He might also develop new abilities related to the creation and destruction of matter.
In this fanfiction, Naruto may develop his patience. Healing is a delicate process and requires time and precision. He would have to learn to be patient, which is a new trait for him. Lee could develop a new sense of humility. Being healed by Naruto, he realizes that he can't always be self - sufficient and that relying on others is not a sign of weakness. This could change his attitude towards teamwork and cooperation in future ninja missions.
One possible development for Naruto is that he begins to show signs of leadership. Even as a baby, he might gather the other village kids around him and lead them in some small play - adventures. For Kushina, she could develop a more nurturing side. She might start to think more about the well - being of the whole village because she realizes that Naruto will grow up in this environment. So, she could be involved in activities that improve the living conditions in the village, all because of her love for Naruto.
Another possible development is that she gains the ability to transform into different forms not just for combat but also for communication. For example, she could take on a more human - like form to better interact with the villagers, which helps to bridge the gap between her and the humans and also shows her adaptability and evolution as a character.
