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.
There are quite a few. In some fanfics, a female character might be inserted into the Naruto universe and end up having adventures alongside Sasuke. These stories can be really engaging as they often put a new spin on the existing Naruto storyline and Sasuke's character development within that new context.
Female Sasuke might have enhanced stealth abilities. In some ninja cultures, female ninjas were known for their grace and ability to blend in, so she could use this to her advantage. Also, she might develop a more intuitive fighting style, relying on her instincts more. Since she's now a girl, her chakra control could potentially be more refined, as some fanfictions depict female characters having a different kind of connection to their chakra.
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.
There are indeed. A lot of fanfiction authors explore different scenarios where a female character is involved with Sasuke and Naruto. For example, some might write about a female character who is caught between Sasuke's brooding nature and Naruto's energetic personality. They could be on a mission together and develop interesting relationships that deviate from the original story line.
Another common theme is redemption. Sasuke has his own dark past, and in female Sasuke fanfiction, female characters sometimes play a role in his journey towards redemption. They might be the ones to show him a different path or help him come to terms with his past actions.
She could also change in how she approaches relationships. Before, as a boy, Sasuke was more reserved in his interactions with others, especially with Naruto. But as a girl, she might be more forward in expressing her feelings towards Naruto, whether it's friendship or something more. This could lead to some really interesting character development arcs and new plot directions in the fanfiction.
I really liked 'The Hidden Bond'. In this fanfic, the relationship between Naruto, Female Gaara and Female Sasuke is explored in depth. It shows how their different personalities interact and create a whole new dynamic. There are some really cool fight scenes and emotional moments that make it a great read.
