In this kind of fanfiction, Naruto might be really frustrated with his friends or the villagers. Maybe he's tired of being misunderstood or underestimated. He could start by calling out their false assumptions about him. For example, if people keep thinking he's just a troublemaker because of the Nine - Tails inside him, he would angrily tell them how he's been trying hard to protect the village all along.
He might target the elders first. They are often the ones who hold the traditional views and might be resistant to Naruto's new ideas. They could be the source of a lot of the problems Naruto is facing in the village.
In such a fanfiction, Naruto might find himself in a very lonely and confusing situation. He would have to relearn about his relationships and the world around him. Maybe he'd be more cautious as he doesn't remember who is friend or foe.
Well, if Naruto is godlike and betrayed by everyone in a fanfic, it could start with the villagers' fear of his newfound power. They might think he's a threat and turn on him. Naruto, being so powerful, could initially be in disbelief. But as the betrayal sinks in, he might decide to leave the Hidden Leaf. He could then wander the world, trying to figure out his place in it while also being cautious of those who might want to take advantage of his power or finish him off.
If in the fanfiction everyone believes Naruto is dead, it would have a huge impact. Firstly, the balance of power in the ninja world would shift. Allies of Konoha might feel less secure. Secondly, the emotional toll on his loved ones would be immense. Hinata would be devastated, and she might struggle to raise Boruto alone. Thirdly, the story could take a turn where Naruto is actually alive but in a different dimension or held captive, and the fanfiction could then focus on the journey to bring him back.
Well, in a fanfiction where everyone sees Naruto's memories, it would be a wild ride. For one, Naruto has so many memories related to his training with Jiraiya. These could inspire the younger generation of ninjas to train harder. His memories of the Akatsuki battles could give the ninja villages a better understanding of their enemies. Also, his personal memories of loss, like the death of his parents, could make the villagers more protective of him and more committed to the idea of peace in the ninja world.
In such a fanfic, Naruto might become extremely bitter. He could lose his positive attitude and turn against the village that once shunned him. Maybe he would seek power elsewhere, perhaps from darker sources.
Perhaps Naruto would immediately reciprocate Sakura's feelings. Given his kind heart and his deep bond with Sakura over the years, he might realize that he has also had underlying romantic feelings for her all along. This could lead to a very sweet and passionate relationship. They would support each other even more in their ninja goals and become an even more formidable team. Their friends would likely be very surprised but also happy for them in the end.
One possibility is that Hinata would be overjoyed. She has loved Naruto for a long time, so his confession would likely make her very happy. She might blush and stammer out a response. Maybe they would share a tender moment and start a relationship right away, with Naruto finally realizing how much Hinata means to him.
Well, one possibility is that Sakura could be initially shocked. She has always seen Naruto as a friend, so this new revelation might make her re - evaluate their relationship. She could start to notice things about Naruto she hadn't before, like his unwavering determination not just in battles but also in his feelings for her.
It could be that his new 'godlike' power has isolated him. People might be either in awe or afraid of him, and he may feel that he can't be close to others as before. So he acts coldly as a defense mechanism.
