Well, in a Naruto changes the past fanfiction, it might change the power balance. Naruto could use his future knowledge to make Konoha stronger earlier. He could teach new jutsus to the younger generation sooner or even prevent some of the big battles from happening. This would lead to a very different ninja world where perhaps there would be more peace and less conflict among the villages.
It can change Naruto's character development significantly. Without Jiraiya's direct influence, Naruto might have to rely more on his own instincts and the knowledge he has already acquired. This could lead to a more independent and self - reliant Naruto.
The character relationships would be greatly affected. In the original story, Naruto had certain bonds with his male friends. But as a female, those relationships could turn into something more complex, like romantic interests or different kinds of friendships. It would also change how the other characters view Naruto's role in the village. For example, some might be more dismissive or some might see her as a symbol of change in the male - dominated village.
If Kushina leaves Minato for Naruto in fanfiction, it would completely change the Naruto universe's family dynamics. Naruto might grow up with a different kind of support system. Instead of the absent father figure of Minato, he could have a more present mother figure in Kushina. This could also change his relationship with the village. Since Kushina was an Uzumaki, her presence could lead to Naruto having an earlier understanding of his heritage.
If Naruto becomes a puppet, it would likely have a huge impact on his relationships. His friends might be initially shocked and confused. Sakura, for instance, would probably be worried about how this transformation affects his humanity. His enemies, on the other hand, would have to re - evaluate their strategies against him. They would no longer be facing the same Naruto they knew before.
In a fanfiction where Naruto dies young, the Nine - Tails within him would be a major factor. Since the Nine - Tails was sealed inside Naruto, its power would be left unmanaged. This could pose a great threat to the village. Without Naruto to keep it in check, the Nine - Tails might break free or be targeted by other villages or villains who want to harness its power for their own evil purposes. It would also mean the end of Naruto's journey to master the Nine - Tails' power and use it for good.
If Kushina and Minato abandoned Naruto in fanfiction, it would completely change the Naruto's character development. Naruto grew up lonely and seeking recognition because he was an orphan. Without their abandonment, he might have had a very different personality, perhaps more confident from the start. Also, the relationships in the village would be different. For example, Iruka might not have had the same special bond with Naruto as he did in the original story.
It could change the power dynamics. Without her memory, Ladybug might not be as effective in using her powers or leading the fight against Hawk Moth. This could lead to a shift in the balance of power in Paris.
Small changes can have a domino effect. If, say, Kakashi was more open about his past earlier, it might make Naruto more determined to solve the mystery of his father's death sooner. This could lead to him training harder and perhaps unlocking new powers faster. So, it can speed up or slow down character development and plot progression.
It alters the theme of the original Naruto story. The original story often emphasized forgiveness and the power of friendship. In this fanfiction, if Naruto kills Haku, it might shift towards a darker theme of sacrifice and the harshness of the ninja world. This could also change how the other characters develop. For instance, Sakura might view Naruto differently, either fearing him or seeing him as a more decisive and perhaps colder hero. And Naruto himself might struggle with guilt or a new - found sense of power that comes from taking a life, which would be a huge departure from his usual self in the original storyline.
Well, it completely turns the original Naruto story on its head. In the original, Naruto was the hero who was supposed to overcome all odds with the Kyuubi's power. But in this fanfiction, his death means that all his future achievements are wiped out. It would be a huge shock to the other characters in the story too.
