It would be quite a shock to the Naruto fandom. Jiraiya is a beloved character and Naruto is the protagonist. For some fans, it would be a very dark and disturbing concept. It might make some fans angry as it goes against the typical relationship and character development in the original series.
Well, in the Naruto fandom, this kind of fanfiction would be a huge departure from the norm. Since Jiraiya is Naruto's mentor and has played such an important role in his growth, it would change the way fans view Naruto's character. It could lead to some fans re - evaluating their love for the series or at least for the fan - made interpretations. It might also lead to new discussions about the nature of heroism and the consequences of characters going against their core values, as Naruto killing Jiraiya would be a major violation of the bond they share in the original story.
The impact would be significant. Since Naruto has such a large and passionate fandom, this fanfiction would be like a bomb. Some fans would stop reading fanfictions altogether if they find this concept too disturbing. Others might start creating counter - fanfictions where they try to rewrite the scenario to something more in line with the original spirit of the series. It could also lead to a decrease in the popularity of the overall fanfiction community related to Naruto if this kind of extreme and negative content becomes more common.
Perhaps in this fanfiction, Jiraiya discovers that Naruto is going to be the cause of a major catastrophe in the future. He might have seen a prophecy or some sort of sign that convinces him Naruto has to die to prevent this. It could also be that Jiraiya has been misled by false information about Naruto, which makes him think that Naruto has become an evil force that needs to be eliminated.
No, it's not popular. In the Naruto fandom, most fans are interested in fanfiction that expands the Naruto world, gives more depth to characters, or creates interesting crossovers. A concept like 'naruto kills fanfiction' goes against the spirit of the fandom which thrives on the creation and sharing of fan - made stories.
One implication is that it could lead to a decrease in the popularity of Naruto fanfiction in general. If the general sentiment is that there's enough, fewer people might be interested in creating or reading new fanfictions.
The Naruto fandom would likely be very divided. Some fans would be extremely outraged as it goes against the core values and character of Naruto. They might condemn such a fanfiction.
The Naruto series has a large and diverse fan base that includes people of different ages. Fanfictions of this nature can have a negative impact on the younger fans who may be exposed to it. The real beauty of the Naruto story lies in its storylines about ninja values, growth, and relationships that are based on respect and camaraderie, not something as inappropriate as this fanfiction.
It can be quite divisive. Some fans might be extremely offended as Naruto is a beloved character known for his positive traits. This type of fanfiction goes against the established character arc and values. It could make some fans angry that someone would distort Naruto's character in such a way.
There could be a 'naruto kills jiraiya fanfiction'. It could be based on a time - travel scenario. For example, if Naruto from the future travels back in time and somehow his actions cause a chain of events that lead to Jiraiya's death. Or perhaps there's a dark, alternate universe where Naruto's values are twisted and he sees Jiraiya as an obstacle to his new, malevolent goals and thus kills him.
One major implication would be his power level. Tsunade is known for her superhuman strength and Jiraiya was a very powerful ninja. Naruto might inherit a combination of their abilities, making him even more formidable. His relationship with other characters would also change. For example, his interactions with Kakashi would be different as Kakashi would be dealing with the son of two of his former comrades. And his standing in the village would be different, perhaps more of a prodigy - like figure from the start.
The implications would be huge. It would completely shatter the positive family image that the Naruto series usually portrays. Fans who love the relationship between Naruto and his parents would be very shocked and possibly offended.
