In this 'Naruto son of crossover fanfiction', it could also focus on the growth of Naruto's son. He might be born with special powers due to the crossover aspect. The story could show how he trains, makes friends and enemies, and tries to live up to his father Naruto's legacy in a world full of new and unexpected elements.
Naruto's son is the central figure for sure. And if it's a crossover with the Dragon Ball universe, characters like Goku or Vegeta might also be important characters. They could interact with Naruto's son, perhaps training him or being his rivals in some way. This would create interesting dynamics between characters from different fictional backgrounds.
The plot might involve Naruto's son being transported to the RWBY universe. He then teams up with the RWBY characters. He could teach them some of his ninja techniques, like how to use chakra. In return, they could show him how to use Dust. Together, they fight against a common enemy that threatens both the ninja world and Remnant.
Well, in fanfiction, anything can be possible. Maybe there could be some sort of multiverse situation where the universes of Naruto and Batman collide. It could be that some powerful magic or advanced technology causes Naruto to end up in Batman's world and through some strange circumstances, Batman becomes his father figure. Or perhaps there are some hidden connections between their families in this fictional scenario that are yet to be discovered.
Well, if we consider the concept of fanfiction, it might involve a lot of creative liberties. One way this could work is if there was a reality - warping event. Say a villain was messing with different universes and ended up combining aspects of Wolverine's genetics with someone in the Naruto world, and Naruto was born as a result. It's all about bending the rules to create an interesting and unique story.
One common theme is power struggle. The second son often has to prove himself in the Naruto world which is full of powerful ninjas. Another theme is identity. He has to figure out who he is in this new context, whether he should hold on to his 'Infamous' identity or adapt to be a part of the Naruto universe.
In the RWBY world, Salem could be a major antagonist. She might view Naruto's son as a threat to her plans for Remnant. His unique powers and knowledge from the ninja world could potentially disrupt her schemes, so she would try to eliminate him.
Perhaps it could be due to a powerful magic that was misfired or experimented with. Dumbledore could have been involved in some sort of arcane experiment that sent his essence or a part of his magic to the Naruto world. This magic then interacted with a local in the Naruto world, and Naruto was born as a result. In this scenario, Naruto would grow up with a strange mix of ninja training and an inherent magical ability that he doesn't fully understand at first, but as he discovers his connection to Dumbledore, he learns to harness it.
It could work if Jupiter had some connection to the chakra system in Naruto's world. For instance, Jupiter's power could be the origin of a very powerful and rare type of chakra. Naruto, being his son in this fanfiction, would have a natural affinity for this special chakra, allowing him to perform feats that no other ninja could. This would change the power dynamics in the Naruto universe significantly.
The plot is full of unexpected twists and turns. Naruto's presence brings a new dynamic to the archer's world, leading to exciting adventures and challenges.
