One good example could be a fanfiction where a female Naruto has a unique adventure with Sasuke. In this story, she might have different powers or a different personality due to being female. Maybe she's more in touch with her emotions and uses that to connect with Sasuke on a deeper level. For instance, she could use her understanding of her own femininity to break through Sasuke's tough exterior. Another example might be a fanfiction where they are in an alternate universe and have to work together to save their world, with the female Naruto bringing new perspectives to their partnership.
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.
One possible plot could be that Naruto, Sasuke and Sakura end up in a situation where they have to form a secret family for a mission. Maybe they have to infiltrate an enemy organization that only allows families to enter. So they pretend to be a family, with Naruto and Sakura as the parents and Sasuke as their adopted son. Along the way, they start to develop real family - like bonds, learning about each other's strengths and weaknesses, and protecting one another.
Well, in many fanfics, the authors might create scenarios where Sasuke shows his secret feelings for Naruto. It could be through small gestures, like protecting Naruto when no one is looking or having internal monologues about his deep connection to Naruto. However, in the original manga and anime, their relationship is complex and while there are strong bonds of friendship and rivalry, it's not as explicitly 'liking' in a romantic sense as some fanfics might depict.
Sasuke would be furious. He's always been protective of Naruto in his own way. He would immediately start looking for her, using all his skills and resources. He might even go on a rampage if he thought Naruto was in serious danger.
If Naruto and female Sasuke had a baby in a fanfiction, it would be a big deal in the ninja world. Their friends like Sakura and Kakashi would be excited and also a bit worried about how to protect the baby. The baby might start showing signs of amazing powers at a young age, like being able to use Rasengan and Chidori at the same time, which would be a very unique ability.
In this fanfiction scenario, the baby of Naruto and female Sasuke would be quite special. Naruto's positive attitude and Sasuke's strong will would be passed on. Their baby might have blonde hair like Naruto and the Sharingan eyes of Sasuke. The story could explore how they protect their child from the threats that still lurk in the ninja world. It could also show how their baby's birth changes the dynamics between the different ninja clans and villages.
Well, in this kind of fanfiction concept, it could be a very interesting plot twist. Naruto, being female, might have some strong motives for kidnapping Sasuke. Maybe she believes she can protect him better this way from the various threats in the Naruto world. It could also lead to a different kind of relationship development between them, far from the traditional friendship or rivalry.
Naruto and Sasuke's relationship would likely become more stable. They would have to put aside their old rivalries for the sake of the 'family'. They might start to see each other as brothers - in - law in a sense. Sakura would be the bridge between them, her love for both of them in different ways helping to ease any remaining tensions. Naruto would probably become more protective of Sasuke, and Sasuke would be more open to Naruto's friendship.
It's not a very common trope. Most Naruto fanfictions focus on their friendship or the original storylines. Killing off a major character like 'female Sasuke' (assuming it's a gender - bent or AU version) goes against the essence of the Naruto - Sasuke relationship in the main series which is more about rivalry and redemption. So it's not something you'll see often in mainstream fanfiction.
