Vegeta could also be a main character in this type of fanfiction. He has that tough - guy exterior which could be appealing to some of the female characters in the Naruto world. He might initially be dismissive of them but as he gets to know them, a harem could form around him. Also, his growth as a character from a proud Saiyan to someone who has a family could add depth to the story. And the female characters from Naruto like Ino might be intrigued by his transformation and power.
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.
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.
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.
One idea could be that a new powerful character arrives in both the Naruto and Dragonball Z universes. This character has a unique charm that attracts the female characters from both worlds. For example, in Naruto, Sakura, Hinata and Ino might be intrigued by this new person's skills and different personality. In Dragonball Z, Bulma, Chi - Chi and Android 18 could also be drawn to them. Another plot could involve a time - travel scenario where a character from one universe travels to the other and creates a harem there, bringing together different fighting styles and relationships.
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.
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.
It's hard to say for sure. Goku in his Super Saiyan Blue form has incredible power levels. But Naruto in his Baryon Mode also has a huge amount of power. However, if we consider the potential of fusing their powers, it might be a character who combines the best of both worlds. Maybe a fusion of Naruto and Goku would be the most powerful. They could have the ki - based attacks of Goku along with the ninja techniques of Naruto.
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.
Another interesting pair could be Sakura and Bulma. Sakura is a strong - willed ninja with medical skills, and Bulma is a brilliant scientist. They could collaborate on creating new technologies or medical treatments. Bulma could be fascinated by the chakra system in the Naruto world and try to find ways to use it in her inventions, while Sakura could learn a lot about advanced technology from Bulma.
Another candidate could be Dialga from Pokemon. Dialga has the power to control time. In a crossover, if it could use its time - control abilities effectively against the Dragonball Z characters, it could be very powerful. For example, it could freeze time and then attack its opponents without them being able to react. But again, Goku has shown the ability to break through all kinds of limitations, so he might still find a way to defeat Dialga in the end.
It could be a new character who is a mix of Naruto and Lelouch. He has Naruto's determination and Lelouch's intelligence. This character could be the center of the harem, with his unique personality attracting female characters from both universes.
