The plot might revolve around how Naruto uses his power to deal with the long - standing problems in the ninja world. He could use it to find a cure for all the ninja - related diseases. And as for the political situation, he could influence the daimyos to make more just decisions for the ninja villages. His relationships with other characters would also change. Some might be in awe of him, while others might be jealous or even afraid.
The story might progress with Naruto becoming a sort of super - protector. He could use the power of all bijuu to defend the Hidden Leaf Village from any threat.
In such a fanfiction, Naruto might start to reshape the ninja world entirely. He could create new jutsus that are unimaginable with normal power limits. He could also travel to different dimensions effortlessly to learn more about the secrets of chakra and ninjutsu, and then bring back that knowledge to improve the lives of everyone in his own world.
The story could progress with Naruto facing new and more powerful enemies. With Frieza's power, he might attract the attention of stronger villains. His friends might also be in more danger as Naruto's new power makes him a bigger target.
He could become more confident, bordering on overconfident. Since he has unlimited strength, he might not face the same challenges in terms of combat, so his development would shift towards moral and ethical challenges.
If Naruto fused with Bardock in fanfiction, the story would likely take a very different turn. At first, Naruto might be confused by his new abilities and instincts. He would need to train to master them. As he does, he would become a more prominent figure in the ninja world. He could potentially change the balance of power. Enemies would be more afraid of him, and allies would look to him for leadership. His journey would be about not only protecting the village but also about understanding his new Saiyan heritage.
The story might progress in a way that Azula uses Naruto for her own purposes at first. Maybe she wants to use his unique abilities in the ninja world to gain an advantage in her own world. But as she spends more time with Naruto, she starts to develop real feelings for him as a surrogate son. This would lead to a change in her character as she becomes more protective and less self - centered.
If Naruto turned into a zombie in fanfiction, the story could progress in several ways. One way is that his zombification could be part of a larger, darker plot. Maybe Orochimaru or some other villain has a hand in it. His friends would then need to search for a cure while also protecting the village from his zombie attacks. Another aspect could be that Naruto's zombie form has some unique abilities that make him both a danger and a mystery. This could lead to different characters trying to understand and control his new powers for their own purposes.
The story could progress with Naruto having to deal with the challenges of his new form. Maybe he has to find a way to reverse the transformation, so he goes on a quest to find a cure. Along the way, he meets old friends and new characters who either help or hinder him.
The story could start with Naruto suddenly finding himself in a giant form. Then he has to quickly figure out how to move without causing too much destruction. As he gets used to his new body, he might start using it to protect the village from threats that normal - sized ninja couldn't handle.
The story might progress with Fuu adapting to the Leaf Village's lifestyle.
