Another storyline could involve Naruto learning about the Uzumaki clan heritage directly from his mother. With Kushina alive, she could teach him about the clan's sealing techniques and their special chakra. This would give Naruto an edge in battles and in his understanding of the ninja world. His relationship with the village might also be different as he has his parents to guide him in dealing with politics and the expectations of being the son of a Hokage.
One possible storyline could be that Naruto grows up with his parents' love and training. He might become an even more powerful ninja at a younger age. Since Minato was a prodigy and Kushina had strong chakra, they could pass on their skills and knowledge early. Naruto could also have a different personality, more confident and less of an outcast as he has a loving family from the start.
One possible storyline could be that Naruto grows up with a strong sense of Uzumaki clan traditions. Since the Uzumaki were known for their sealing techniques, Naruto might be trained in that from a young age. He could use these skills in unique ways during his adventures, like creating more powerful seals than in the original story.
One possible storyline could be that Naruto grows up with a strong sense of family. He would be trained by Minato from a young age, learning advanced jutsu much earlier. With Kushina's loving care, he might not have the same insecurities. For example, he could be more confident in school and among his peers. He might also have a closer relationship with the Uzumaki clan, as Kushina would surely teach him about their heritage.
One possible storyline could be that with his parents alive, Dark Naruto might not have turned so dark in the first place. His parents' love and guidance could have steered him away from the path of darkness. For example, Minato, being a powerful ninja, could have trained Naruto properly from a young age, and Kushina could have provided the emotional support he needed. This would change the whole dynamic of the Naruto universe as we know it, and there would be no need for him to seek power in dark ways.
Naruto's social skills would also be different. Instead of being the lonely outcast, he would be part of a family. He would interact with other ninja kids in a more positive way. His parents could also guide him in making friends. He might be more diplomatic in his relationships because he has seen how his father, as the Hokage, dealt with people. This would all contribute to a very different Naruto compared to the one we know from the original series.
In such a fanfiction, Naruto would likely grow up with a strong sense of family. He'd be trained by his father, Minato, from an early age, perhaps becoming a prodigy even faster. His mother, Kushina, would fill his life with love and warmth, and he might not have the same underdog status as in the original. He could be more confident and less of a prankster, having a stable home environment.
One possible storyline could be that Naruto's parents, Minato and Kushina, are alive and they train Naruto from a young age. This would make Naruto an even more powerful ninja earlier on. He would grow up with their love and support, and perhaps not be as much of an outcast in the village as he was in the original story.
One possible plotline could be that Iruka instills in Naruto a deeper sense of self - worth from a very young age. Since Naruto has always been starved for recognition, Iruka's positive influence might make Naruto more confident in his abilities earlier. For example, he could start training more seriously and master certain jutsu faster. Another plotline might involve Iruka protecting Naruto from some of the harsher elements in the village that Naruto would have otherwise faced alone. This could lead to a different dynamic between Naruto and the villagers as they might see Naruto in a new light because of Iruka's actions. A third plotline could be that Iruka, being Naruto's main caregiver, helps Naruto understand his parents better. Maybe Iruka discovers some hidden secrets about Naruto's parents and shares them with Naruto at the right time, which gives Naruto a new sense of purpose and connection to his family heritage.
Perhaps Naruto is raised in a non - ninja community. He could grow up with normal people and have no idea about his chakra or ninja heritage at first. But then, some events might occur that expose his true nature and draw him into the ninja world. He would have a very different perspective compared to a Konoha - raised Naruto, as he didn't have the indoctrination of the ninja village from a young age.
A possible storyline is that Naruto starts to suspect that there was a darker reason for his parents leaving him. This could lead to a conflict within himself, whether to forgive them or not. He could also meet other orphans in the village and form a sort of support group. They could work together to change the village's perception of orphans. Another idea is that Naruto discovers a secret about his parents that puts him in danger, and he has to fight to protect that secret while also coming to terms with his feelings of abandonment.
Perhaps in the fanfiction, the snap is only the first step of a much larger plan by Thanos. After the snap, he uses the resulting chaos to try and reshape the universe in his image. The heroes must not only deal with the loss from the snap but also stop Thanos' grander scheme which involves complex magical and technological elements that they have never faced before.
