In this fanfiction, it could start with a strange portal or some sort of magic that links the two universes. Naruto might be shocked to find out he has a Saiyan cousin. Vegeta, on the other hand, would probably be initially dismissive. But as they get to know each other, they could learn from each other's fighting styles. Naruto could teach Vegeta about the importance of friendship in battle, while Vegeta could show Naruto some of the more advanced energy - based attacks of the Saiyans.
The story could also explore how their families are related. There could be a long - lost connection between the Uzumaki clan and the Saiyan royal family. This could lead to all sorts of adventures as they try to uncover the truth. Maybe there are ancient prophecies that involve both of them. And as they face common enemies, they combine their powers. Naruto's Rasengan and Vegeta's Galick Gun could be combined in some epic battles against foes that threaten both their worlds.
Well, in fanfiction, anything can be possible. Maybe in a multiverse concept where the boundaries between the Naruto and Dragon Ball universes are blurred. A wizard or some super powerful entity could have manipulated events to make Naruto Vegeta's son. It could also be a result of some time - travel shenanigans where Naruto's origin gets intertwined with Vegeta's family line in an alternate timeline.
One way Naruto could be related to Vegeta in fanfiction is through a crossover of universes. Maybe a powerful magic or some sort of interdimensional rift brings them together. Then they could discover that they are related through some ancient prophecy or a long - lost family connection that spans across different anime worlds.
Well, on the surface, Naruto and Batman seem like two very different characters from different universes. But in fanfiction, anything can be possible. Maybe they could be brothers if there was some sort of multiverse crossover. For example, if there was a dimension where the shinobi world and Gotham City co - existed. Naruto's values of loyalty and never giving up could blend well with Batman's determination. However, it would be a very strange combination considering Naruto's bright and energetic nature compared to Batman's brooding and dark persona.
It could work if there was a shared backstory created for them. Perhaps they both have a common ancestor or some ancient power that links them. Naruto's strong sense of loyalty and protection could be extended to Natsu as his younger brother. He could teach Natsu some of his ninja values like never giving up and the importance of teamwork. Natsu, in turn, could show Naruto the more carefree and adventurous side of the Fairy Tail world.
Well, it's a really wild concept. Maybe in a multiverse where the laws of different fictional worlds collide. Naruto's ninja skills and Bruce Wayne's detective and combat abilities could create some interesting storylines. For example, they could team up to fight a common enemy that somehow spans both their universes, like a super - powered criminal organization that uses both high - tech gadgets and ninja - like stealth.
A really interesting plot could be that Vegeta's planet was actually created by an ancient Uzumaki clan member long ago. And the Saiyans are descendants of that creation in a way. So Naruto being Vegeta's cousin is a sign of a much deeper connection. When Naruto discovers this, he travels to Vegeta's planet to learn more about his heritage. There, he has to deal with the Saiyan politics and the distrust of some Saiyans towards him.
Well, in a fanfiction context, it's possible through creative liberties. Maybe some sort of alternate universe where the X - Men world and Naruto's world collide in a way that Jean Grey has a connection to Naruto's birth. It could involve some kind of time - travel or cross - dimensional magic. However, it's a very strange combination as the two universes have different rules and power systems.
Perhaps in a fanfiction, a time - traveling scenario occurs. Vegeta travels back in time and ends up in the Naruto universe. There, he falls in love with a kunoichi and has a child. Generations pass, and Naruto is related to that child's line, thus making him related to Vegeta. It's a wild and wacky idea but could make for an interesting fanfiction.
Well, one way it could work is if Naruto somehow discovers the world of Final Fantasy VII where Sephiroth exists. Maybe through a strange jutsu gone wrong or a mysterious portal. Naruto, being curious, would be intrigued by Sephiroth's power. He might see Sephiroth as a powerful figure to learn from in terms of combat skills, not realizing the dark nature of Sephiroth at first.
One way this could work in the fanfiction is if there was a powerful being or artifact that manipulated genetics or destinies. This being could have decided to combine the power of Thor, an Asgardian god, with the potential of Naruto from the ninja world. So, Naruto being Thor's son would mean he has both the power of chakra and the might of Asgardian powers like lightning manipulation, which would make for a very exciting and unique story.
