In a crossover fanfiction, it could be that the power of Devil Fruits from One Piece becomes known in the Dragonball universe. Vegeta, being his prideful self, wants to obtain a Devil Fruit power to make himself even stronger. He travels to the One Piece world and accidentally ends up on the Thousand Sunny. The Straw Hat crew initially see him as a threat but then realize they can help each other. They end up in a big adventure together where they combine their powers to fight a new common enemy that threatens both universes.
Zoro and Vegeta would also have a great interaction. Zoro, with his strong sense of honor and his goal of becoming the world's greatest swordsman, would be a worthy opponent for Vegeta. Vegeta would be interested in Zoro's swordsmanship and might even see him as a potential rival. They could have some intense training sessions together, sharing their knowledge of combat and power - up techniques.
Another plot could involve the Devil Fruits from One Piece and the Ki powers in Dragonball. For example, a character could eat a Devil Fruit that gives them the ability to manipulate Ki in a unique way. Or perhaps a Dragonball character accidentally eats a Devil Fruit while visiting the One Piece world and has to deal with the consequences, like not being able to swim.
Luffy and Goku would be an amazing combination. Luffy's carefree and determined nature combined with Goku's love for fighting and protecting the innocent could lead to some really fun and exciting adventures. They could learn from each other's fighting styles, with Luffy being inspired by Goku's Ki - based attacks and Goku being intrigued by Luffy's Devil Fruit abilities.
One common theme is power comparison. Fans like to see how the powerful characters from each series stack up against each other. Another is adventure. Combining the grand adventures of One Piece with the epic battles of Dragonball Z.
Well, it could be about the Straw Hats accidentally ending up in the Marvel universe. They meet the Avengers and at first there's some misunderstanding because of their different ways. But then they realize they can work together. Maybe Luffy is fascinated by Thor's hammer and tries to lift it, while Zoro wants to have a sword fight with Captain America's shield.
One common theme is the clash of combat styles. For example, when Zoro crosses over to a world like Naruto's, his swordsmanship clashes with ninjutsu. Another theme is adaptation. Zoro has to adapt to new environments, like if he's in a world with different magic systems or cultures.
Sure. There are many fanfics out there that combine these two great series. One popular one might be those that feature crossovers in battles. For example, Luffy from One Piece might team up with Goku from Dragonball Z to fight a common enemy. You can usually find such fanfics on popular fanfiction websites like FanFiction.net or Archive of Our Own.
It's really hard to say. Goku from Dragonball has insane power levels that can destroy planets. But Naruto has his own unique abilities like the Nine - Tails' power and his Sage Mode. And if a god is involved, it could be the most powerful as gods usually have omnipotent powers in fanfictions. But it really depends on how the author writes it.
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.
