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.
Naruto could develop a stronger sense of responsibility. He is marrying Kushina, so he has to take care of her and think about their future. This might lead to him being more cautious in his actions. Kushina, on the other hand, may develop a more open - minded attitude. She might start to accept new ideas and ways of life that Naruto brings to her.
Kushina, on the other hand, might experience a loss of agency which could lead to her character growing in different ways. She could fight against Naruto's control, which would show her strong - willed nature. Or she could come to accept it and use it as an opportunity to guide Naruto in a different way. There could be a role reversal of sorts where she becomes the voice of reason in Naruto's head. And this could lead to a very different kind of relationship between them compared to what we know from the original story.
In this fanfiction, Naruto could develop a new set of skills related to childcare. He would learn how to make baby Sasuke happy, feed him, and put him to sleep. Sasuke, on the other hand, could start to see Naruto as a true brother figure from a very young age, which would shape his personality and relationships in the future.
In a fanfiction, Sakura could develop her leadership skills. If she and Kushina are in a situation where they need to lead a group, Sakura could learn from Kushina's natural charisma. Kushina could also develop her relationships with the new generation. She could start to see the potential in Sakura and other young ninjas and become a mentor figure, which would be a new role for her compared to her previous life.
One possible character development could be Naruto's role as an older, more established figure. Instead of being the young, energetic hero, he would be more of a father figure. His attitude towards the village and his comrades might be more paternal. He might be more focused on protecting Kushina and guiding her, rather than going on adventures as in the original story.
Naruto could become more confident. With Kushina as his maid, he'd have someone who truly believes in him at home all the time. He might grow out of some of his insecurities faster. For Kushina, she could develop a new sense of purpose. Instead of just being a memory or a lost hero, she's actively involved in Naruto's life again.
Naruto, as a baby, could start to develop a sense of trust and security that he didn't have before. With Kakashi around, he could grow up believing in the power of friendship earlier. And as he grows up in this fanfiction, he might be more confident in his abilities because of Kakashi's early training.
In this fanfiction, Naruto might experience some significant character development. He could initially be very confused and conflicted about the situation. On one hand, he has his mother as a servant, which is a strange and uncomfortable idea. This could lead to him being more introspective. As time goes on, he might start to see Kushina's value in a new light, not just as his mother but as someone who is loyal to him in this new role. This could make him more empathetic towards others in servant - like positions. He may also become more decisive in his actions, as he now has someone directly under his authority and has to make decisions regarding Kushina's tasks and well - being.
Fem Naruto might develop a more motherly or nurturing side. Kushina was known for her strong personality and also her love for her family. Fem Naruto could inherit some of these traits and become more protective of her friends, almost like a mother figure to them. This would be a significant change from the original Naruto's character in some aspects.
Shikamaru would probably become more involved in village politics to ensure a good future for his child. He'd use his intelligence to make connections and secure resources. His character would shift from just being a member of a team to a family man with big responsibilities. Sakura would find a new balance between her ninja duties and motherhood. She might train other female ninjas on how to handle both aspects. Her love for Shikamaru would grow as she sees him change and become more committed to their family.
