It's hard to say. If Naruto is truly godlike, he could be very strong. But Goku has his own amazing power - ups. Maybe in the end, it would depend on how the author writes it. If Naruto can combine his ninja skills with his new godlike powers in a really clever way, he could be the strongest. But Goku's Super Saiyan forms are no joke either.
Well, it could be amazing. Picture Naruto with godlike powers in the DBZ universe. He might be able to use his chakra in new ways, like combining it with ki. For example, his Rasengan could be super - charged with ki energy, making it an even more powerful attack. And he could learn to fly like the DBZ characters, adding a whole new dimension to his abilities.
Bulma from DBZ can also be a popular character in these fanfictions. She's smart and resourceful. In a story with a godlike Naruto, she might be the one coming up with the plans to use Naruto's powers in new ways or to help the group get out of tough situations. Also, characters like Kakashi from Naruto can bring their unique skills and mentoring - like qualities to the fanfiction.
In some fanfictions, a godlike Naruto might find himself in the DBZ universe and have to adapt to their power - level system. He could learn ki manipulation from the Z - fighters and in turn, teach them about chakra. This interaction between the two different power concepts can lead to really engaging plots.
A godlike Naruto DBZ crossover fanfiction might focus on a combined threat that requires both Naruto and the Z - fighters to team up. Maybe an evil entity from the Naruto world somehow gets access to the Dragon Balls and wishes for ultimate power. Naruto and Goku would then have to put aside their differences in fighting styles and cultures to defeat this new foe. They could learn from each other's determination and loyalty to their friends along the way.
One possible plot could be Naruto arriving in the DBZ universe and quickly realizing he has to adapt to the new power levels. He might start training with Goku to learn about ki, while also teaching Goku about chakra. Their combined skills could then be used to face a new, powerful enemy that threatens both universes.
Goku would likely be Naruto's strongest ally. Goku is always open to new training and new friends. His pure heart and love for fighting would mesh well with Naruto's own determination and will to protect. They could learn from each other's fighting styles and power - ups, creating a very powerful duo.
However, it might not be just about Naruto or Goku. A new character created through the fusion of Naruto and Goku's powers could potentially be the most powerful. This character would have the best of both worlds - the Saiyan's fighting instincts and raw power along with Naruto's strategic thinking and unique ninja abilities.
Well, one interesting aspect could be the combination of Naruto and DBZ elements. Maybe the fanfic gives Naruto god - like powers similar to those in DBZ, like super strength or the ability to fly. It could also explore how Naruto's character would change with such powers in a new and exciting story setting.
Obviously Naruto would be one of the main characters since it's in the title. And probably some of his friends from the Naruto series like Sasuke or Sakura. Since it's combined with DBZ, there might also be characters from DBZ like Goku or Vegeta. They could either be allies or rivals to the godlike Naruto.
