One of the best crossovers could be the combination of power - ups. For example, Naruto's Sage Mode combined with Goku's Super Saiyan form. It would be interesting to see how their powers interact and if they could learn from each other's fighting styles.
Bulma from Dragon Ball Z in Naruto fanfiction has potential. She is smart and resourceful. In the Naruto world, she could use her intelligence to create new technologies or help with strategic planning during battles, and her interactions with the ninja characters would add a new dimension to the story.
There might be a fanfiction that focuses on Vegeta and Bulma's relationship in a more in - depth way. It could show how they handle their differences while also dealing with the Saiyan - Earthling cultural clashes. This type of story can add a lot of depth to their relationship and show sides of the characters that we don't see as much in the official story.
The exploration of different worlds is another interesting aspect. Naruto's world of hidden villages, forests, and unique landscapes, and Dragonball Z's planets, like Namek and Planet Vegeta. A fanfiction could have characters traveling between these worlds, learning about the different cultures and technologies, and using them to their advantage in battles or in their quests.
You can try fanfiction websites like FanFiction.net. There are a large number of Dragonball Z fanfictions there, and you can search specifically for ones that might have the elements you're interested in. Just make sure to read the reviews and ratings to find the better - quality ones.
Well, one possible plot could be that Naruto and Goku somehow end up in each other's universes. Naruto could be intrigued by the concept of ki and try to learn it, while Goku might be interested in Naruto's ninja skills like shadow clones. They could team up to fight a common enemy, perhaps a new villain created by fusing some of the bad guys from both universes, like a combination of Orochimaru and Frieza.
In a crossover, it really depends on how the powers are combined. If Naruto could somehow combine the Nine - Tails' chakra with Sage Mode and then learn some ki techniques from the Dragonball Z side, he could be extremely powerful. But Goku has been training for a long time and has access to godly ki. So he would be a top contender as well. Vegeta too, with his own determination and power - ups, could also be in the running for the strongest.
Well, it could be really exciting. Picture Naruto with Goku's ability to go Super Saiyan. Maybe Naruto could learn the Kaio - ken technique. The story could involve the two universes colliding, with villains from both sides teaming up. So Naruto and his friends from Konoha would have to join forces with Goku and the Z - fighters to save both their worlds.
Goku could be an interesting main character for such a fanfiction. He already has a lot of charm and is extremely powerful. His naivete in some ways could make it fun as he tries to understand the different female characters from the Naruto universe. For example, he might be confused by Sakura's dual nature of being tough but also having a soft side. Another option could be Naruto himself. He has his own charisma and his never - give - up attitude would attract the female characters from Dragonball Z, like Bulma might be interested in his determination.
It's hard to say. Goku in his Super Saiyan forms has incredible power and can destroy planets. But Naruto has the Nine - Tails' power and Sage Mode. If we consider Naruto at his peak with all the tailed beasts' power combined, he could give Goku a tough fight. However, Goku's ability to constantly increase his power level might give him an edge in the long run.
