In a Kyuubi Naruto - themed fanfic, Hinata's character could develop in her self - discovery. The power of the Kyuubi in Naruto represents a great and somewhat chaotic force. Hinata, in contrast, is calm and gentle. By interacting with Naruto in this context, she could start to explore different aspects of herself. She might find that she has a hidden strength within her that she didn't know before. This could lead to her being more adventurous, trying new things, and not being afraid to show her true self. For instance, she could start to be more vocal about her ideas and feelings, which is a big step forward from her usually shy self.
Hinata could start training with Naruto specifically to understand the Kyuubi's power better. This would not only bring them closer but also let her learn new techniques. As she trains, she might discover hidden aspects of her own Byakugan in relation to the Kyuubi's chakra, which would develop her character in terms of power and knowledge.
His confidence would soar. With Kyuubi's training, Naruto would realize his true potential and become more self - assured. He'd be less likely to doubt himself in battles.
His character could become more complex. He might struggle with his new identity as part Kyuubi. There could be internal conflicts between his human side and the Kyuubi side.
Naruto's character could develop a greater sense of responsibility towards Hinata and her family. Saving her mom would make him more aware of the importance of family bonds, which could in turn influence his own views on his family and his place in the village.
Naruto's character could become more empathetic. Hinata's kindness and understanding might help Naruto see things from different perspectives. For example, he might start to consider the feelings of his opponents more often during battles.
Naruto's development would be shaped by his interactions. In this fanfic, he'll be surrounded by kunoichi, which will change his view on gender roles in the ninja world. The Fem Kyuubi could be a catalyst for his growth. Maybe she has a tragic past that makes Naruto more determined to protect others. He'll also have to deal with the jealousy or admiration of the kunoichi towards him. All these factors will contribute to a Naruto who is more adaptable, understanding, and powerful in both physical and emotional aspects.
Naruto would likely become more responsible. He's used to being the hero, but now he has to be a father too. So he might cut back on some of his risky adventures to be there for his family. Hinata would become more confident as a mother. She's always been a bit shy, but with a baby to protect, she'd find her inner strength.
In many fanfictions, Hinata's confidence grows. For example, she might start taking on more leadership roles in missions with Naruto. Since she has always been shy, in fanfiction, she could break out of her shell more, especially when Naruto is in danger. She becomes more assertive in protecting him and their relationship.
Hinata may become more assertive. Since she has Naruto as her 'weapon', she has to take on a more leading role. She might have to make decisions about when and how to use Naruto's powers, which could make her grow in confidence.
Well, Naruto's character would develop in a unique way. He would grow up with a different set of values compared to the original Naruto. Since he is adopted by the Kyuubi, he would have a deeper understanding of power and its responsibilities. He would be more in tune with his inner self, as the Kyuubi would help him explore his chakra and his true nature. He might also be more aloof from the other villagers at first, as he has a special bond with the Kyuubi, but as he grows, he would use his new - found knowledge and power to bridge the gap between them and show them that he is not the outcast they thought he was.
