It changes the team dynamics. Instead of Sakura's role as the healer and her relationship with Naruto and Sasuke, the replacement character brings in new interactions. For example, if a more aggressive character replaces her, there would be more arguments within the team.
It changes the dynamics a great deal. Instead of the typical unrequited love from Naruto towards Sakura in the original, it flips the script. This makes their interactions less about Naruto pining for Sakura and more about a platonic friendship. They might interact more casually and without the underlying tension of unspoken love.
It changes the original story by adding an element of foresight to Naruto's character. In the original, Naruto mostly reacts to situations as they happen. But in precognition fanfiction, he can anticipate events. This can lead to different battle outcomes. For instance, he might avoid a dangerous ambush that he would have otherwise walked into in the original story.
The fanfiction might change Naruto's character development. In the original, he grows through his ninja experiences. But with bionic enhancements, he may have to face different challenges, like dealing with glitches in his bionic parts or being feared by those who don't understand his new nature. This would lead to a different kind of growth for him.
In the original Naruto story, the theme of friendship and loyalty is strong. In 'naruto betrayed fanfiction', this theme is flipped on its head. Betrayal becomes the central theme. The story may also explore different aspects of Naruto's character. For instance, how he copes with the pain of betrayal. It might show his darker side as he tries to seek revenge or find out why he was betrayed. This is very different from the Naruto in the official story who is always striving to protect and befriend others.
Well, it completely flips it. Instead of Naruto being his own self and having his normal interactions with Sakura, he now has to experience things from her perspective. He might be more empathetic towards her feelings, especially her insecurities, which he might not have fully understood before.
They become more united as they face the challenges of parenting together. Their relationship deepens as they share the joys and sorrows of raising a child.
It often changes drastically. Sakura may initially feel hurt and angry. She might start to question all her previous beliefs about Naruto. For example, if Naruto betrays her trust in a battle situation by seemingly siding with the enemy, Sakura's view of him as a reliable friend and teammate would be shattered.
In fanfiction, Naruto's character can change in terms of his social skills. Since he has a strong affection for Sakura, he may become more outgoing and sociable in an attempt to get closer to her. He could start spending more time with Sakura's friends, which is a big change from his previous focus mainly on his own small group of friends. His values might also shift. For example, he might start to value Sakura's opinions more than anyone else's, and this could influence his decisions in various aspects of his life, like when choosing missions or dealing with village politics.
They often rewrite character relationships. For example, in the original, Sasuke was Naruto's important rival and friend, but in bashing fanfictions, Sasuke might be made into a completely negative character who is just a nuisance to Naruto. Sakura's role as a healer and a friend in the original can be distorted in these fanfictions too, maybe shown as a character with no real purpose. Overall, the emotional depth and growth that the three characters had in the original Naruto story can be completely altered.
Well, in the original series, Naruto has a crush on Sakura. But in this fanfiction, if he despises her, it completely flips their dynamic. They might not have those friendly interactions anymore and instead be more distant or even hostile towards each other.
