It could entail Naruto having a very different upbringing. Since he's older, he might have to take on more responsibilities in the family. He could be the one to protect Minato from the early threats that Minato faced in the original story.
The story could explore how Naruto's presence changes the course of Minato's life. Maybe Minato doesn't become Hokage as early as he did in the original. Naruto might encourage Minato to focus on other aspects of life first, like building stronger relationships with his friends and family. This could lead to a more well - rounded Minato in the long run.
There could be a lot of emotional moments. For example, Naruto might feel a great sense of pride when Minato shows his natural talent for ninjutsu. And Minato could look up to Naruto as a role model. Also, Naruto could be involved in Minato's training in new and different ways compared to the original story.
Perhaps in this fanfiction, Naruto has to keep his identity a secret from Minato. He could be from an alternate future where things went wrong, and he's there to make sure Minato becomes Hokage and prevents certain disasters. So he has to subtly guide Minato without revealing who he really is.
Well, it would be a really wild concept. Naruto's ninja world and Vegeta's Saiyan heritage are so different. Maybe Naruto would teach Vegeta some ninja skills like stealth and using chakra in unique ways. And Vegeta might introduce Naruto to Saiyan combat techniques. It could be a story full of clashes between their different values and powers, but also of them learning from each other.
There probably is. Fanfiction is a place where writers can reimagine relationships. If Kyuubi was Naruto's older brother, it could rewrite many aspects of Naruto's life. For example, Naruto might have had a different upbringing with Kyuubi around. And it could also affect how Naruto deals with his enemies, as he would have the power and guidance of his older brother Kyuubi. It's a really interesting concept that fanfic writers might explore.
It could involve Naruto teaching Brandish about his ninja village and the importance of comradeship. Brandish might learn to use some of Naruto's ninja skills in addition to her magic.
One possible plot could be Naruto protecting Serena from various threats in their world. Since Naruto is known for his determination and strength, he would use his ninja skills to keep Serena safe. Maybe they live in a world where both ninja and other magical elements exist, and Serena has some special power that makes her a target, and Naruto is constantly on guard.
It could be full of action. Naruto would bring his ninja skills to Issei's world. He might train Issei in combat, much like he trained with Sasuke and others. Their relationship could also be full of brotherly banter and support.
If Naruto were Itachi's older brother in fanfiction, the power dynamics in the Uchiha clan could be very different. Naruto's influence might prevent the Uchiha massacre. He could use his positive and determined attitude to change Itachi's view of the village. Also, Naruto's relationship with Sasuke would be completely redefined, as he would be Sasuke's older brother's older brother. This could lead to a more united front against the real threats in the Naruto world.
One implication could be a different power dynamic. Instead of Naruto inheriting Minato's legacy as his son, they would be more like peers sharing similar powers. Maybe Naruto wouldn't have the same kind of lonely childhood as in the original story.
In such a fanfiction, Naruto could have a big influence on Kushina's life. For example, he might train her earlier, sharing his ninja knowledge with her. Their relationship could also affect how Kushina views the Uzumaki clan and her place in it. Since Naruto is known for his determination, he could inspire Kushina to be stronger and more confident in this alternate scenario. This would likely lead to a different chain of events in the story, perhaps changing the way the whole Uzumaki clan is perceived in the Naruto world.
The concept in fanfiction often involves re - imagining the Naruto world's power dynamics and relationships. If Naruto is Minato's brother, it could lead to different political situations within the village. Naruto might be more involved in the village's inner workings earlier. His training could be more specialized as he might inherit some of Minato's unique skills or knowledge. And his relationships with characters like Kakashi, who was Minato's student, would take on new and interesting dimensions.
