For the female Naruto, her character can be developed by emphasizing her femininity in a way that affects her ninja skills. For example, she might be more agile or have a more precise chakra control. Sasuke, on the other hand, could be developed to be more open to her influence. Instead of his usual brooding self, he could be shown to be gradually softened by her presence. Maybe he starts to show more emotions and becomes more communicative.
In a secret female Naruto and Sasuke fanfiction, the female Naruto could be developed with a stronger sense of community. Since she's female, she might be more interested in building relationships within the village. This could contrast with Sasuke's more solitary nature.

This development would change their dynamic, making their interactions more about mutual growth rather than just Sasuke's personal journey.
Well, in some fanfictions, instead of the typical rivalry starting early, Naruto could be like an older brother figure to toddler Sasuke right from the start. He could teach Sasuke simple things like how to climb a tree or catch a fish, which would build a strong bond of trust and friendship between them.
In the original series, Naruto is mainly focused on becoming Hokage and getting Sasuke back. In the fanfiction, as Anbu Naruto, he might be more secretive and have a darker side. He could be more cynical about the village's politics. Female Sasuke, on the other hand, may be more independent than in the original. She could be more involved in political matters in the village rather than just seeking revenge. For example, she might use her skills to try and reform the ninja system.
Well, in a fanfiction, Sasuke could be more open and friendly towards Naruto from the start. Instead of their rivalry, they could become like brothers immediately.

This would change the whole dynamic of their relationships. For example, they could all train together as a group more often.
Dark Naruto could be developed to have a different set of ninja skills. He might learn some forbidden jutsu on his own in his journey to the dark side, which gives him an edge over others. In terms of Fem Sasuke, she could be more in tune with her feminine side. Instead of just being cold and brooding like the original Sasuke, she could use her charm and intelligence to get what she wants. For instance, when dealing with enemies, she might use her wits to outsmart them rather than always relying on brute force. Also, Dark Naruto could have a more philosophical side, constantly questioning the nature of power and the ninja world, which is different from the more impulsive original Naruto.
In the baby Sasuke Naruto fanfiction, if Naruto was raised by a family of scholars, he could develop a more intellectual side early on. He might still be loud and energetic, but also have a love for learning and strategy. Sasuke, on the other hand, if he was part of a big, warm family, could be more outgoing and less cold - hearted. His competitiveness could be more about friendly rivalries rather than a deep - seated need to prove himself.
For Fem Naruto, her character could be developed to be more in touch with her femininity while still maintaining her strong - willed and determined nature. She could use her charm in addition to her combat skills to get what she wants. Shisui, on the other hand, could be developed to be more open about his feelings. In the original, he was rather reserved. In the fanfiction, he could be shown to be more vulnerable, especially around Fem Naruto.

In some fanfictions, Naruto, Hinata and Sasuke's relationships can be drastically different. Naruto and Hinata could start a relationship based on a shared interest in a new form of ninjutsu that Hinata discovers. This brings them closer together in a way that wasn't shown in the original. Sasuke, on the other hand, could be forced to live with Naruto and Hinata for a period of time due to some village regulations. During this time, he sees their relationship up close and it makes him re - evaluate his own ideas about relationships and loyalty. He might start to see the value in what Naruto and Hinata have and become more protective of them.
For Hinata, her normally shy and reserved nature could be twisted into a more calculating and cold - hearted one in the dark fanfiction. She might use her byakugan not for protection but for manipulation. Naruto, on the other hand, instead of his usual optimistic self, could become more cynical after facing multiple betrayals, especially if Hinata is involved in some of them.
Sasuke in fanfiction could be developed with more vulnerability. In the original series, he is often seen as stoic and brooding. But in fanfiction set in the ANBU world, he might show his fears and doubts more as he has to deal with the high - stakes and secrecy of ANBU missions. Sakura could be more assertive. In the original, she sometimes seems to be in Sasuke's shadow. Here, she could be an equal or even a leader in ANBU operations. The ANBU environment forces both of them to grow in new ways.
