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.
No. Naruto and Laxus are from two completely different anime universes, Naruto and Fairy Tail respectively. While fanfiction can play around with all sorts of wild ideas, making Naruto Laxus' older brother is not a mainstream or even a common fanfiction concept. It would require a lot of creative world - building to make such a relationship seem plausible. For example, the writer would have to explain how Naruto, with his ninja skills and chakra system, could exist in the world of magic like Fairy Tail and have a family - like connection with Laxus. But as of now, this is not a typical fanfiction scenario.
Yes, there might be such fanfictions out there. The idea of crossing over two very different anime universes like Naruto and High School DxD (where Issei is from) and creating a family - like bond between the characters is an interesting concept that fanfiction writers might explore.
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.
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.
Family bonds are a common theme. The older brother - Naruto relationship is explored deeply, showing how they support each other, protect each other, and grow together. It's often about filling a gap in Naruto's life that was left by his lack of family growing up.
Well, one way it could work is if there was some sort of multiverse crossover concept. Maybe in a world where different fictional universes collide. Naruto's skills like his shadow clone jutsu could be used in interesting ways to help Wonder Woman in battles. He could also teach her about the importance of friendship and determination which are big themes in his story.
One popular 'naruto older brother crossover fanfiction' is where Naruto has an older brother from another anime universe, like from 'One Piece'. In this type of fanfic, the older brother often brings new skills and a different perspective to the Naruto world. It can be really exciting to see how their relationship develops and how they interact with other Naruto characters.
Well, for one, Kakashi's childhood might have been different. Naruto could have been there to support him after his father's death. Also, Naruto might have influenced Kakashi's attitude towards the Sharingan. He could have been more cautious about Kakashi using it, given its toll on the user.
