Fem Naruto's appearance would change in several ways. Her body shape would be more feminine, with curves. Her eyes might be a bit larger and more expressive. In terms of hair, not only would it be long, but she could also style it in different ways, like braids or ponytails. And her skin tone might be a bit fairer compared to Naruto. She would also have a more slender build overall.
Well, for starters, as a female, she'd have a more petite frame compared to Naruto. Her hair would be long and could be of a different color or shade, perhaps a lighter blond. Her facial features would be more refined, with a smaller nose and more pronounced lips. Her ninja gear might be customized to fit her female form, maybe with some added accessories like a headband with a flower or something more girly. Also, her overall posture and movement might be more graceful, which is a characteristic often associated with female characters.
Well, in some fanfictions, fem Naruto's mother could be a powerful figure, and her interaction with Kurenai could be quite complex. Kurenai, being a skilled kunoichi, might respect fem Naruto's mother for her own abilities. They could exchange knowledge about jutsus or strategies. It could also be that they have a mentor - mentee kind of relationship, with one teaching the other some unique ninja techniques.
He might be more calm. Since the female Kurama could be a stable influence, Naruto wouldn't be as impulsive.
Well, when Fem Naruto wears the Kyuubi in fanfiction, her appearance can change in several ways. Her hair could become wilder and more voluminous, as if it has a life of its own, similar to the untamed nature of the Kyuubi. Also, she may have a sort of glowing aura around her, which is a manifestation of the Kyuubi's power. Her clothes might also transform to something more in line with the Kyuubi's aesthetic, perhaps with red and orange patterns that resemble the Kyuubi's fur.
It changes the Naruto narrative by adding a new dynamic to the relationship with the Kyuubi. Instead of the traditional, often more combative relationship, the fem Kyuubi can bring a more nurturing aspect. For example, she might teach Naruto things in a different way.
Fem Itachi changes the Naruto universe by adding a different dynamic to the power structure. Her female presence brings a new perspective. For instance, she might approach battles and negotiations differently than male characters. She could also influence the relationships between characters. If she becomes friends with Naruto early on, she might change how he views certain clans or ninja techniques.
Naruto's relationship with his peers would be greatly altered. Since he was raised by a kitsune, he might not fit in as well with the other ninja trainees at first. But as for his relationship with the fem Kyuubi, it could be a complex mix of trust and wariness. She is a powerful being, and Naruto would have to navigate their relationship carefully. He might rely on her for power, but also fear her potential for destruction. His relationship with the hidden leaf village elders would also be a point of conflict as they might not understand his new powers and alliances.
It changes the Naruto universe by adding a new element of magic. In the original Naruto, there is mainly ninja magic. But with fem Naruto being a mermaid, there is now water - based magic. For example, she could use her mermaid powers to create water barriers or communicate with sea creatures, which is completely different from what normal ninjas can do.
It changes the Naruto universe in several ways. Firstly, Fem Orochimaru's actions would be different from the male Orochimaru's. Her motives for taking Naruto might not be as purely power - hungry. This could lead to different alliances and enmities. For example, some characters who were against Orochimaru might be more lenient towards Fem Orochimaru if she shows a more benevolent side. Secondly, Naruto's growth and development would be altered. Instead of following the path with Jiraiya, he's with Fem Orochimaru. So his jutsu and combat style might incorporate more of her unorthodox and perhaps more feminine - influenced techniques. Also, the perception of Orochimaru's lair or hideouts would change. It could be less of a spooky, evil - filled place and more of a place of mystery and potential redemption.
She would probably have an eye patch, which would give her a more rugged and battle - hardened look. Her overall expression might become more serious, as the loss of an eye is no small thing. The remaining eye would likely become more intense, as if it has to make up for the loss of the other one.
Another possibility is that it's a result of some strange chakra experiment gone wrong (or right). Scientists in the Naruto universe are always dabbling in chakra research. Maybe an experiment meant to enhance her natural abilities instead gives her the Rinnegan, and she then has to learn to control it quickly to avoid being consumed by its power.
