What could be the plot of a fanfiction where Kyuubi is Naruto's older brother?

One possible plot could be that Naruto, having grown up in a different world, suddenly discovers he has a sister in Erza's world. He travels to her world to protect her. Along the way, he has to learn about the magic in the Fairy Tail world while also teaching Erza some of his ninja skills. They could face a common enemy that threatens both their worlds, and their combined skills would be crucial in the fight.

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.

The plot could start with Naruto's arrival in the Fairy Tail world. As Laxus' older brother, he would immediately take on a protective role. He could use his rasengan and other jutsu to fight off enemies that threaten Laxus or the guild. Naruto might also try to bridge the gap between the two different power systems - chakra and magic. Along the way, there could be a lot of character development for both Naruto and Laxus. Laxus could learn about Naruto's past and the struggles he had in his own world, which would inspire him to be a better mage. And Naruto would adapt to the Fairy Tail world, using his skills to help the guild grow and protect it from internal and external threats.

One possible plot could be that Naruto grows up knowing about his relation to Tsunade. He could be trained in the art of medical ninjutsu by Tsunade's family, and then use his unique Uzumaki chakra to enhance it. As Tsunade's older brother, he might be very protective of her, especially after the death of her loved ones. He could play a key role in helping Tsunade become the Hokage, perhaps by convincing the village elders that she is the right choice, using his own influence as a respected ninja.

The older brother in the fanfiction might be a character with a tragic past. For example, he could have been experimented on by Orochimaru and gained some strange powers as a result. And he returns to the village later to protect Naruto from the threats that are coming towards him.

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.

One possible plot could be that Naruto discovers a deeper spiritual connection with the Kyuubi. As mates, they start to communicate in a more profound way, not just the normal exchanges when Naruto draws on the Kyuubi's power. They might share memories and emotions, and together face threats to the ninja world that only their combined strength and new - found relationship can overcome.

Well, an interesting plot point might be how their different ninja abilities are influenced by their brotherly bond. Since Naruto has the Nine - Tails, he could train Sasuke to better handle his Sharingan. And in terms of the story, when Sasuke is faced with the truth about Itachi, Naruto as his older brother could be there to comfort him and help him make a more rational decision instead of just seeking revenge. There could also be a plot point where the village starts to suspect their relation and how they deal with that suspicion together.

Yes, there might be such fanfictions out there. Fanfiction writers often come up with creative crossovers like this. You can try searching on popular fanfiction websites using relevant keywords like 'Naruto Issei older brother' to find them.

Sure, there are likely fanfictions with this premise. Fanfiction thrives on taking established characters and putting them in unexpected situations. If Naruto were Kakashi's older brother, it would completely change the Naruto universe as we know it. It might mean that Naruto would have a different role in Kakashi's life, perhaps being more protective or having a say in his training. Also, it could impact the story arcs that involve Kakashi, as Naruto's presence as an older brother would add a whole new layer of complexity to his decisions and actions.
