The storyline could start with Naruto somehow ending up in Aizen's world. At first, he would be confused and on guard. But as he gets to know Aizen, he might see some potential in him. Naruto would try to change Aizen from the inside. Aizen, on the other hand, might see Naruto as a useful tool or an interesting experiment.
In this fanfiction, the development could be quite complex. Naruto is used to a world where friendship and teamwork are highly valued. Aizen's world is full of intrigue and power plays. Naruto might try to introduce his values to Aizen's followers. This could cause a rift among Aizen's forces, some might be attracted to Naruto's way, while others would be loyal to Aizen's old ways. And as for Aizen himself, he might be intrigued by Naruto's chakra and try to study it, which could lead to all sorts of conflicts and revelations.
Well, if Naruto were pregnant and joined Akatsuki, it would be a very strange situation. Firstly, the Akatsuki is a group of S - class criminals. Naruto, being a hero in the original story, would face a huge conflict of values. His pregnancy would add another layer of complexity. Maybe he would try to use his situation to change Akatsuki from within, or perhaps he would be forced to keep his pregnancy a secret for fear of how the other members would react. It could also lead to some members of Akatsuki having a change of heart, seeing Naruto in this vulnerable state.
In such a fanfiction, the story might develop as Batman discovers secrets about Darkseid that he thinks he can use to his advantage. He could be playing a long - game, pretending to be on Darkseid's side while actually planning to bring him down. However, Darkseid is no fool and would likely test Batman's loyalty. Meanwhile, the rest of the DC universe would be in chaos as they try to figure out why Batman has turned and how to stop him if he's truly gone bad.
Their relationship would likely start with mutual respect. Naruto already respected Itachi after learning of his sacrifice. Once they join in the fanfiction, they would gradually become friends. They'd rely on each other in battles, and Itachi might start to see Naruto as a younger brother figure, much like Sasuke. Naruto, on the other hand, would look up to Itachi's skills and wisdom.
The story could start with Naruto finding Obito in a desolate place. Naruto would be curious and approach him. Then, they would exchange words, and Naruto would offer his help to Obito. As they interact more, they might face some small - scale battles together against rogue ninjas or other threats. This would build trust between them.
Naruto's character would likely become more conflicted. He has always been on the side of good, and joining Orochimaru, even if for a good reason, would put him in a morally gray area. His view of power might change as he is exposed to Orochimaru's unorthodox ways of obtaining it.
The story would take a very different turn. Naruto's godlike abilities would give Akatsuki an edge in battles. But his values would clash with the group's. This could lead to him either changing Akatsuki or being forced out. It would also affect his relationships with his old friends in Konoha. They might see him as a traitor at first, but as the story unfolds, they could come to understand his motives.
The character development of Zabuza and Haku would be very different. Usually, they are portrayed as somewhat cold and isolated characters. But with Naruto around, they would be exposed to his warmth and positive attitude. Haku might develop more self - confidence and Zabuza could learn to trust others more. This would not only change their individual storylines but also how they interact with other characters in the long run.
The Soul Reapers would be very confused at first. They are used to Aizen being a certain way, and Naruto's different personality would be a shock. Ichigo might be curious and see Naruto - Aizen as an ally against the common enemies. Orihime could be one of the first to trust Naruto - Aizen because of his kind - hearted nature that she would sense. And the Espadas would probably be on high alert, not knowing what to expect from this new Aizen.
If Naruto joins the Uchiha clan, his character would develop in several ways. He would have to adapt to the clan's hierarchical structure. This could make him more respectful of traditions. His relationship with Sasuke would take on a whole new dimension. They could become more like brothers within the clan, and Naruto would have a stronger sense of family. Also, his understanding of power and responsibility would grow as he learns about the Uchiha's power - hungry past and how it led to their downfall.
Naruto's character would likely become more reserved at first. The neglect he has faced has made him a bit jaded. But as he proves himself in ANBU, his confidence would start to return. He would also become more stealthy and calculating, traits he didn't really have to rely on before. His sense of loyalty to the village would be tested and strengthened as he faces more complex and dangerous situations within ANBU.
