A plot twist could be that Naruto, being Kushina's brother, has a different mentor. Instead of Jiraiya, he could be trained by an older Uzumaki clan member who has unique abilities. This would shape his fighting style and ninja skills in a whole new way. Also, his relationships with his peers would be different. For example, Sasuke might see him as more of a threat since he has a stronger connection to the Uzumaki clan, which was known for its powerful ninjas. This could lead to more intense rivalries and battles between them.
A plot twist could be that they see Naruto losing his way. This would be a huge shock for them as they always believed in Naruto's goodness. But then, as the story unfolds, Naruto finds his way back due to a memory or a message from his parents that he somehow receives in a moment of crisis.
One possible plot twist could be that Naruto, instead of seeking acceptance in the village, decides to leave and find his own path outside. He might discover a hidden group or power that the village was unaware of and use it to come back and prove himself to his parents. Another twist could be that Naruto is taken in by an enemy of the village who sees his potential and trains him to be a powerful ninja, but for their own evil purposes. However, Naruto, having been ignored by his parents, might be more susceptible to this false sense of belonging.
Yes, there are likely some fanfictions out there with this premise. Fanfiction often takes creative liberties with the original Naruto story. Writers might explore how this relationship would change the story's dynamics, character interactions, and plotlines. It could lead to very different character development for Naruto and how he is related to other characters in the Naruto universe.
One possible plot twist could be that Kushina's survival was part of a grand plan by an unknown entity. Maybe she was hidden away to protect Naruto from some greater threat that was yet to be revealed. Another aspect could be the emotional turmoil Naruto would go through. He'd be overjoyed, of course, but also confused and maybe a bit angry that he was made to believe she was dead all this time.
One possible plot twist could be that Naruto initially resists the arranged marriage because he has feelings for someone else, like Sakura. But as he gets to know Kushina, he discovers that they have a lot in common. For example, they both have a strong will and a love for their village. This could lead to a slow - burning romance where they gradually fall in love.
One possible plot twist could be that with Minato and Kushina alive, Naruto's training would be completely different. Minato, being a prodigy, could teach Naruto advanced jutsu much earlier. And Kushina might pass on some unique Uzumaki clan techniques. Maybe they would also change the political situation in Konoha, as Minato was a highly respected Hokage. This could lead to different alliances and power dynamics within the village and among the other ninja villages.
There could be a plot twist where they are revived in a different time period. Maybe they are brought back during the era of the Sage of Six Paths. This would mean they have to adapt to a very different world with different rules and powers. Another plot twist could be that when they are revived, they are linked to an ancient evil. They have to fight this internal connection while also trying to figure out what has happened to the ninja world in their absence. Additionally, it could be that their revival was actually a test by the gods of the ninja world to see if they can bring about a new era of peace.
Maybe the plot is centered around Kushina's relationships. She gets to meet her son Naruto as an adult and is proud of the man he has become. She also reconnects with old friends and allies. But then, there are those who are not happy about her return, fearing that she might disrupt the current power balance in the village, and Naruto has to defend her.
In one possibility, Kushina could use her chakra chains to fend off attackers. Since she was a powerful kunoichi, she might sense Naruto in danger and appear in a moment of need. Maybe Naruto is facing a powerful enemy like Pain, and Kushina's sudden arrival and her unique abilities turn the tide of the battle, saving Naruto from certain death.
Well, if Naruto were Kushina's older brother, the whole story of Naruto would be turned on its head. The story would start with Naruto already having a family connection to the Uzumaki clan. His training and development would likely be different as he would have grown up with Kushina. He might have learned some unique Uzumaki techniques from their family. His relationship with the other characters would also change. For instance, his relationship with Jiraiya might be different as Jiraiya might also see Naruto in a different light due to his relation to Kushina. And when it comes to the big events in the Naruto universe, Naruto would be in a position to directly influence Kushina's actions, which could change the course of many events.
