Naruto himself could develop in terms of his power and understanding of the world. With the female Juubi around, he might learn new chakra techniques that are related to her unique abilities. Also, his leadership skills could improve as he tries to guide the female Juubi in the right direction. He has to balance being firm and being understanding towards her.
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.
For Naruto, he could become more refined in his skills and strategies under Female Kakashi's influence. He might also learn to be more patient and observant, taking after Kakashi's calm demeanor. For Female Kakashi, she could become more open and warm - hearted, influenced by Naruto's positive energy and his ability to see the good in people.
Harribel could also experience character growth. Through her relationship with female Naruto, she might learn about the importance of hope and never - giving - up spirit. Female Naruto's constant determination in the face of adversity could inspire Harribel to be more open - minded and less reserved. This could lead to Harribel being more involved in the affairs of others, rather than just focusing on her own domain.
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.
A female Itachi could have a more empathetic character development. Since in many interpretations, females are often seen as more in touch with their emotions. She might struggle more openly with the decision to sacrifice her family for the greater good. For example, she could have more internal conflict shown through her relationships with Sasuke and other Uchiha members. This would make her character more complex and relatable.
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.
Well, one possible consequence could be that Naruto gains an enormous boost in power. The Juubi is an extremely powerful entity in the Naruto universe. With it, Naruto might be able to easily defeat his enemies. He could also potentially use the Juubi's power to protect his village in ways he couldn't before, like creating super - strong barriers or launching large - scale attacks against threats.
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.
