While Naruto and Gohan are the central focus, the fanfic could also introduce new characters created specifically for this story. These new characters could be neighbors or someone who is affected by the presence of Naruto and Gohan living together, which would then drive the plot forward in new and unexpected ways.
The plot could involve them facing a common enemy. Since they both come from different but powerful universes, their combined strength would be interesting to explore. They could start as strangers in the fanfic, gradually become friends while living together, and then team up to fight this new threat.
Gohan's adaptation in the Naruto world in this fanfic would be a complex process. He would be faced with a world full of new rules, new powers, and new people. At first, he'd be confused, but his intelligence would help him. He'd study chakra, the most fundamental part of the Naruto world. He might also be intrigued by the different jutsu and try to incorporate some of the principles into his own fighting style. Socially, he'd have to learn the ways of the ninja, like their loyalty to their villages. Over time, he could become an important part of the Naruto world, using his Saiyan abilities in new and unique ways that blend with the ninja way.
Naruto would probably be very enthusiastic and eager to make friends with the yokai students. He might show off his ninja skills to impress them. Gohan, being more reserved, would be a bit more cautious at first. But once he gets to know some of the yokai students, he would be friendly and helpful. For example, Naruto could teach some of the yokai simple ninja moves, and Gohan could offer to help with any academic problems the yokai students have.
Well, it could be about Gohan and Naruto teaming up to fight a common powerful enemy. Maybe an evil force from another dimension is threatening both their worlds, and they have to combine their unique powers and skills to save the day.
Obviously, Gohan and Naruto are must - includes. They are the main characters that can drive the story forward. But also, characters like Piccolo from Dragon Ball can add an interesting dynamic. He could act as a mentor figure to some of the Naruto characters, teaching them about self - discipline. In Naruto's world, Kakashi could also be included. He could be intrigued by Gohan's power and try to learn from him about different forms of combat.
Another idea for a 'Gohan Naruto' fanfic is a story set in a world where the Dragon Ball and Naruto universes are merged. Gohan could attend the Ninja Academy in Konoha. He would struggle with some of the regular ninja training like stealth, as he is used to more straightforward battles. But he would also bring his own skills to the table, like flying, which would amaze his classmates.
It could be a powerful demon that has the ability to absorb the powers of others. This demon has been observing both Gohan and Naruto from the shadows and wants to take their powers to become invincible.
One possible plot could be that Gohan and Naruto are brought together by some sort of interdimensional rift. They initially misunderstand each other's powers but soon realize they share a common goal of protecting their respective worlds. They then team up to fight a powerful villain who is threatening both their universes.
In a fanfic where Gohan goes to the Naruto world, his presence would disrupt the balance. His Saiyan strength is on a different level compared to most Naruto characters. He might start by being confused about the ninja way and all the different clans. However, he could also introduce new concepts from his world. For example, his training methods. And he would probably make some really strange friends. Some ninjas might be in awe of his power, while others might be a bit scared. He could also end up having some really interesting battles against the strongest ninjas, like Naruto or Sasuke, which would be a clash of two very different power systems.
