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.
In this type of fanfiction, the story might progress in a rather comical way. Naruto in his chibi form would attract a lot of attention, both good and bad. His friends would try to protect him while also teasing him. As he continues his journey, he discovers new abilities or powers that are unique to his chibi state. This could lead to him being more powerful in some ways than he was before, which would be a big twist in the story.
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.
Well, in such a fanfiction, Naruto would be super cute as a chibi. He might have trouble being taken seriously by his friends at first. His powerful jutsu could look really funny in a smaller form, like the Rasengan might be like a tiny spinning ball in his little hands.
The story could progress with Harry trying to find a way to turn back. He might search for ancient spells or magical artifacts that could reverse his condition. His friends would be desperate to help him, and they'd start their own investigations. Maybe Hermione would scour the library for any information on wraiths and how to reverse the transformation.
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.
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.
The story would likely start with chaos as Goku's sudden appearance would be a huge shock. His actions would drive the plot. For example, if he accidentally destroyed part of a village while testing his power, the ninja would either see him as a threat or try to get his help against other enemies.
The story could progress with a lot of humor. Naruto might accidentally use Sasuke's Sharingan in a silly way, like when he's trying to eat ramen. Sasuke in Naruto's body would probably get into trouble for Naruto's over - enthusiastic behavior. This would lead to them trying to find a way to switch back as soon as possible while also dealing with the chaos they've created.
The story might progress with her facing discrimination at first from some of the Kumo natives. But as she proves herself through her hard work and determination, she gains respect. She could also discover some secrets about her family or Konoha while in Kumo that would add more depth to the story. And she'd gradually form her own team and go on missions together, forging strong bonds with her Kumo comrades.
