Perhaps Fem Sasuke in this fanfiction has a different view of the world. She might believe that Naruto is a threat to her goals or to the future of the ninja world she envisions. It could also be that she has some deep - seated emotional pain that she blames Naruto for, and that leads her to kill him.
Well, it's not that common. Most Naruto fanfictions tend to focus on their friendship or the idea of them working together. However, the concept of Fem Sasuke killing Naruto could be used to show a different side of the Naruto universe, like a more tragic or alternate reality where things go horribly wrong. It might attract those who are interested in exploring the darker aspects of the story.
There could be. Fanfiction allows for a wide range of interpretations and alternate storylines. But it's a really extreme and disturbing concept considering the bonds that Naruto, Sakura, and Sasuke share in the official story. It would be a very different take on the characters, and most fans who love the original story would probably find it hard to accept.
Also, it allows for a deeper exploration of gender roles in the Naruto universe. A fem Naruto might face discrimination or different opportunities compared to male Naruto. How Sasuke responds to this, whether he becomes more protective or if it makes him view her differently, is a fascinating aspect. It gives readers a chance to see the Naruto world through a different lens, one that challenges the traditional male - centered narrative.
Their relationship can be developed through shared experiences. For example, going on dangerous missions together. Each time they face a new threat, they learn more about each other's abilities and personalities. Naruto's positive attitude can slowly break down Fem Sasuke's more reserved nature.
One common theme is friendship. Since Naruto and Sasuke's relationship is so central in the original series, in fem versions, their friendship or evolving bond is often explored. Another theme is rivalry, but with a different female - centered dynamic. For example, how they compete in a world that might have different expectations for female ninjas.
This type of fanfiction concept is really out of the ordinary. Naruto's character is built on his values of friendship, loyalty, and his dream of becoming Hokage. Killing Sasuke would mean betraying all of that. However, in a fanfiction, the author might be exploring the 'what - if' scenario. For example, what if Sasuke's actions against Konoha were so heinous that Naruto felt he had no choice? But still, it's a far - fetched and very different view from the original Naruto we know.
This kind of fanfiction usually explores alternate storylines and character dynamics. It might be based on intense conflicts or unexpected plot twists.
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.
I'm not sure if there is such a specific fanfiction available. Fanfiction can cover a vast range of themes and ideas, but this one seems rather unorthodox. You can try searching on popular fanfiction websites to see if it exists.
