There could be. Fanfiction writers often like to take established characters and put them in unexpected situations. But it's important to note that this would completely change the dynamics of the Naruto story. Hinata is typically shown as someone who respects and admires Neji in the original series. So if such a fanfiction exists, it would be a very radical re - imagining of their relationship.
Yes, there might be such a fanfiction. In the Naruto fandom, with its large and diverse range of fan - created works, various out - of - canon scenarios are explored. However, this goes against the original storyline where Hinata and Neji have a complex relationship that is more about growth, understanding, and family bonds rather than such a violent act.
I'm not entirely sure if there is a specific 'Naruto Hinata kills Neji' fanfiction. Fanfiction can cover a vast array of ideas, and while some might explore dark or alternate storylines like this, it may not be a common or widely known one. The Naruto series generally portrays Hinata as a gentle character, so this would be a very extreme deviation from her character.
One possible plot could be that Hinata is somehow mind - controlled. Maybe an enemy uses a powerful genjutsu on her that makes her see Neji as a threat to Naruto or to the village. Under this influence, she attacks and kills Neji, which then leads to a great deal of guilt and self - loathing for Hinata once she breaks free from the control.
Well, there might be some very niche or non - canon fanfictions out there with such a plot, but it's not a common or widely - accepted idea in the Naruto fan community. Naruto and Hinata have a well - established relationship in the main series, and Neji is Hinata's cousin, which makes such a relationship in the context of cheating even more inappropriate and not in line with the general themes of the series.
In fanfiction, such a plot would be extremely dark and out of character for Naruto. Naruto is typically portrayed as someone who values his friends and comrades, especially Hinata who he has deep emotional connections with. It could be a very edgy take in the fanfic world, perhaps exploring some extreme 'what - if' scenarios or alternate universes where Naruto has been corrupted or misinformed in some way.
In the Naruto universe, Naruto killing Neji would be a very dark and out - of - character turn. However, in fanfiction, it could be due to some dark influence like a powerful and evil genjutsu that overpowers Naruto's mind and makes him see Neji as an enemy. Maybe a villain has managed to manipulate Naruto's perception of reality to make him commit such an act.
On a larger scale, the balance of power in the ninja world could be affected. Neji was a strong and capable shinobi, and his absence could create opportunities for enemies to take advantage. Naruto's actions could also damage the reputation of Konoha as a whole. Other villages might view Konoha as unstable or dangerous if one of their most well - known shinobi can turn on his own comrades. This could lead to increased tensions and potential conflicts between the different ninja villages.
It's a very controversial plot. Neji is an important character in Naruto, and his relationship with Naruto is complex but not one of enmity to that extreme. In the original story, they are comrades. So a fanfic with such a plot goes against the general spirit of the Naruto world and would shock many fans.
In some fanfictions, Naruto might use his new jutsu skills that he's developed in secret training. He could surprise Neji with a powerful Rasengan variant, overpowering him and rescuing Hinata.
One way is through his brute strength. Naruto is very powerful and he can simply overpower Neji in a physical confrontation. He can block Neji's Gentle Fist attacks with his own strength and speed.
Well, Naruto could use his shadow clone technique. He'd create multiple clones to surround Hinata and keep Neji at bay. Naruto has a strong sense of justice and cares deeply for Hinata, so he'd do whatever it takes. He might also try to talk Neji down, appealing to their shared experiences and values, while positioning himself between Neji and Hinata to block any potential physical attacks.
Another possibility is a complete character distortion in the fanfiction. The writer might decide to create a 'bad Naruto' version where he has lost all his positive traits. However, this is quite far - fetched considering the strong foundation of Naruto's character in the original series. It would be a very different and probably controversial take on the Naruto - Hinata relationship.
