What could be an interesting plot in a Pokemon and Dragonball Z crossover fanfiction?

One possible plot could be that the Sailor Scouts are facing a new and extremely powerful enemy that they can't defeat on their own. Goku and his friends from Dragonball Z sense the danger across the dimensions and come to help. The Scouts are initially shocked by the Saiyans' power levels but then start to learn from them about ki control. Together, they combine their powers, like the Sailor Scouts using their magic with the Z - fighters' ki blasts to take on the foe.

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.

Well, perhaps the Dragon Balls are accidentally sent to the Naruto universe. Naruto and his friends then have to figure out what these strange orbs are. Meanwhile, Goku and his pals come looking for the Dragon Balls and end up meeting Naruto. They could exchange their different fighting styles and techniques, like Naruto teaching Goku about chakra control and Goku showing Naruto how to sense ki.

Well, a cool concept for Pokemon and Dragonball Z fanfiction could be that the energy in the Dragonball Z world affects Pokemon in strange ways. For example, Pikachu could learn to use Ki blasts. Also, a story where the Z - fighters visit the Pokemon regions and have to participate in Pokemon battles to save the day. And a more complex idea would be a fusion of the two worlds' power systems. Say, a Pokemon trainer figures out how to use Ki to enhance their Pokemon's abilities, and in turn, the Pokemon help the trainer in combat against the powerful foes in the Dragonball Z world.

A Sailor Moon and Dragonball Z crossover fanfiction might start with a strange rift in the universes. Sailor Mercury detects an unusual energy signature that seems to be a mix of magic and ki. As they investigate, they run into Goku who is also curious. The two groups then find out that there's a powerful being trying to merge their worlds for its own evil purposes. The Sailor Guardians and the Z - fighters would then have to put aside their differences in fighting techniques and beliefs to stop this threat. They might have some funny moments like Vegeta getting annoyed with Sailor Mars' sassy attitude or Sailor Venus being in awe of Goku's strength.

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.

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.

Ruby could have an interesting interaction with Vegeta. Vegeta is known for his pride and his drive to be the strongest. Ruby, with her own set of skills, might either be a target of his envy or someone he could respect. For example, if Ruby has a unique power that Vegeta can't easily understand, it could pique his interest or make him feel threatened.

One interesting Dragonball Z fanfiction could be about an alternate universe where Goku never hit his head as a baby. In this story, he might grow up as a full - blooded Saiyan with a more aggressive nature. Another could focus on Vegeta's life on Planet Vegeta before it was destroyed, exploring his family and early training. And there are also fanfictions that bring in new characters, like a half - Saiyan half - Namekian who has unique powers and plays a crucial role in a new threat to the universe.

One idea could be that the characters from RWBY gain the ability to use Ki like in Dragonball Z. For example, Ruby could use her speed along with Ki blasts in a new and powerful way. Another plot could involve the villains from both universes teaming up, forcing the heroes to combine their skills and powers. Or perhaps there could be a tournament in the style of the World Martial Arts Tournament where characters from both RWBY and Dragonball Z participate.
