In a 'Goku raises Naruto' fanfiction, Goku might instill in Naruto a stronger sense of self - confidence. Naruto has his own confidence issues despite his bravado at times. Goku, who has always been confident in his abilities, could help Naruto truly believe in himself. Goku could also introduce Naruto to the concept of Super Saiyan transformations, and Naruto might find a way to incorporate that kind of power - up into his own ninja skills, creating a whole new form of his own that combines the best of both worlds.
Well, one possibility is that Goku, with his powerful Saiyan abilities and big heart, teaches Naruto new combat techniques. Maybe he shows Naruto how to better control his chakra by using some of the principles of Ki control in the Saiyan way. For example, Goku could help Naruto reach new levels of power in his Rasengan by adding elements of his Kamehameha's energy concentration.
Well, the plot could involve Naruto being a huge fan of Goku through some kind of inter - dimensional viewing device. He starts to mimic Goku's training regime, much to the confusion of his friends in Konoha. Then, an evil force from the Dragon Ball universe somehow crosses over to Naruto's world. Naruto, with his new - found inspiration from Goku, decides to take on this threat, and in the process, he might even convince Goku to come and help him save his world. Along the way, there could be lots of comical moments as Naruto tries to explain ninja concepts to Goku and vice - versa.
One possible plot could be that Naruto discovers an orphaned child during one of his missions. He decides to take the child under his wing and raise it as his own. He would teach the child ninjutsu, just like Jiraiya taught him, and also instill in the child the values of hard work and loyalty.
One possible plot could be Naruto taking on the role of a mentor and father figure to Naruko. He might teach her all the ninja skills he has learned, like how to perform the Rasengan. And also, he could guide her in understanding the importance of friendship and loyalty, just as he experienced with his own friends in the original series.
The plot could also involve Naruto raising Kaguya to be a force for good in a world that still has remnants of evil. Kaguya, with Naruto's guidance, could use her vast power to help in rebuilding areas damaged by past wars. Naruto may also introduce her to the concept of family, which she may have lost touch with long ago, and this new understanding could transform her character completely.
In a 'naruto raises sarada fanfiction', perhaps Naruto discovers Sarada's potential early on. He starts by training her in basic ninja skills like chakra control. As she grows, he could involve her in more complex tasks within the village. Naruto might also help Sarada deal with the pressure of being the daughter of Sasuke and Sakura. He could encourage her to find her own identity as a ninja rather than just living in her parents' shadow. For example, Naruto could arrange for her to train with other young ninjas from different clans to broaden her perspective and skills.
Perhaps the story could start with Naruto having strange dreams about Goku's life. As the story progresses, he gradually unlocks Goku's powers. He could then use these powers to protect the Hidden Leaf Village in a more powerful way. For instance, when the village is under attack by a powerful enemy, Naruto could transform into a Super Saiyan - like state, shocking his enemies and allies alike. His training would also change, as he'd have to learn to control his new Saiyan powers, which would be a whole new journey for him.
In a 'Goku adopts Naruto' fanfiction, perhaps Goku accidentally travels to the Naruto universe. He comes across Naruto, who is an outcast in his village at that time. Goku, not understanding the social structure but seeing Naruto's potential and loneliness, decides to adopt him. Goku teaches Naruto about the concept of Super Saiyan and how to harness his inner power in a different way. Naruto, in turn, shows Goku the beauty of ninja techniques. They might end up fighting against the Akatsuki together, with Naruto using his newfound Saiyan - like strength and Goku using some ninja - inspired moves.
One possible plot could be that Naruto, as Goku's brother, has to learn the ways of ki while also maintaining his ninja skills. Maybe they team up to fight a common enemy that threatens both the ninja world and the Dragon Ball universe.
In a 'Naruto descendant of Goku' fanfiction, the plot could involve the discovery of a hidden bloodline in the Naruto universe that is related to Goku. This descendant might initially be an outcast because of their strange powers. However, as the story progresses, they start to show the true potential of their combined heritage. They could teach the ninjas about ki control, which is similar to chakra control in some ways. And in turn, they learn about the complex political and social structures of the ninja world from Naruto and others.
Well, it could be that Goku somehow ends up in the Naruto universe and has a son with a female character there. And this son has both the powers of a Saiyan like super strength and the ability to use chakra for jutsus. Maybe he's an outcast at first because of his strange powers but then becomes a hero.
