In fan - made stories, the Kyuubi can have a more collaborative relationship with the characters. It may work with other jinchuriki or ninja in ways not seen in the original. It could also be a key factor in crossovers, if the fanfiction involves Naruto characters interacting with those from other series. For example, its power might be used to bridge different fictional universes together.
In the original series, Naruto was a ninja striving to be recognized and protect his village. As a 'god' in the fanfiction, he is no longer just a village protector but more of a universal overseer. He has powers that far exceed his original capabilities, like being able to control the fate of entire nations instead of just fighting individual battles.
In the original Naruto series, Tayuya was mainly portrayed as a villainous character. But in the fanfiction, she could be given more sympathetic traits. Maybe she has a softer side that was hidden before.
In fanfic, it might be more exaggerated. The kicks could be shown with even greater force and speed. For example, in the original series, Sanji's kicks are already powerful, but in fanfic, an author could make them so strong that they can create shockwaves that can level small buildings.
In the original Naruto series, Naruto is male and his development is centered around his male - centric experiences like proving himself to the male - dominated ninja world. In Fem Naruto x Kyuubi fanfiction, Fem Naruto may face different types of discrimination. For example, she might have to fight against the sexist ideas that a female can't handle the power of the Kyuubi. Her development could be more about breaking gender barriers in addition to becoming a strong ninja.
The original Naruto story is centered around Naruto's journey to become a respected ninja, make friends, and protect his village. In the 'evil kyuubi naruto fanfiction', the focus shifts. It might explore how the evil Kyuubi affects Naruto's relationships in a negative way. His friends may not trust him as much, and his enemies may try to use his new, darker state to their advantage. The fanfiction may also have a different aesthetic, with darker themes and settings to match the evil nature of the Kyuubi - influenced Naruto.
In fanfiction, his time in Azkaban might be more about his internal struggle and growth. He may use his time to discover new magical abilities or gain a deeper understanding of the wizarding world's politics. In the original series, he never actually experiences Azkaban, so this is a completely new scenario in fanfiction.
In the original Naruto story, Naruto has a more adversarial relationship with the Kyuubi at first. He has to struggle to gain control over the Kyuubi's power. However, in the 'naruto worships fem kyuubi fanfiction', the relationship is based on worship, which is a completely different dynamic. This would lead to different interactions between the two characters, and different plot developments.
The way the Kyuubi breaks free is also likely to be different. In the original, it's a big, chaotic event. In the fanfiction, it could be more of a strategic move on the part of the fem Kyuubi. Maybe she's breaking free to save Naruto from a hidden enemy or a plot within the village that the normal Naruto wouldn't be aware of. This would change the whole direction of the story compared to the original where Naruto is mainly focused on becoming stronger on his own terms.
In the original series, we follow Naruto's growth in terms of his ninja skills and relationships. However, in 'naruto is a mystery fanfiction', there could be a shift towards uncovering secrets. For instance, instead of just fighting Akatsuki, the characters might be trying to figure out the Akatsuki's true motives and hidden plans, which were not the central focus in the original.
The main difference is the focus on Naruto's son. In the original series, Naruto was the main character. Also, the fanfiction may introduce new villains or story arcs related to the son.
