Perhaps Naruto starts to focus on self - improvement to prove his worth despite his family's neglect. He could train extra hard and develop unique skills that set him apart. This would not only make him stronger physically but also more confident in himself.
Well, a plotline could be that Naruto, ignored by his family, starts to explore the darker side of the crossover world. Maybe he gets involved with some shadowy organizations because he feels that no one in his family cares what he does. He could also start a journey to find out why his family is ignoring him. Along the way, he meets various characters who either help or hinder him in his quest. Another possibility is that Naruto, feeling the pain of family neglect, decides to create his own family - like group with his friends in the crossover world and they work together to change the situation for the better.
One interesting plotline could be Iruka officially adopting Naruto. It would show how Iruka helps Naruto grow in a more family - like environment. For example, Iruka could teach Naruto about their family traditions and values.
Well, a great plotline could be the Uzumaki family facing a new, powerful enemy that specifically targets their clan. Naruto, along with his parents and other family members, would have to band together to fight this threat. It could show how the family dynamic works, with everyone having their own strengths and weaknesses. Maybe Naruto's mother uses her sealing jutsu in a creative way to protect the family, while Minato uses his speed to outmaneuver the enemy. This would also be a chance to see Naruto grow within the family unit.
One possible plotline could be Naruto growing up feeling extremely lonely and trying to find ways to gain his parents' attention even though they're not around. He might start to excel in ninja training not just to prove himself to the village but also in the hope that his parents would be proud if they were there. Another could be Naruto having vivid dreams about his parents and then waking up to the harsh reality of their absence, which could fuel his determination to find out more about them and why they ignored him.
Another plotline could be Female Orochimaru's attempts to reconcile with the Hidden Leaf. She might try to use her skills to help the village in secret at first, and then gradually gain the trust of the villagers. This would involve her interacting with Naruto and other characters in positive ways, like helping with rebuilding efforts or teaching new ninja techniques to the younger generation.
One interesting plotline could be that Naruto and Tsunade are part of a charity organization in a modern city. Naruto uses his natural charisma to attract donors, while Tsunade, with her experience, manages the finances and operations. Their relationship grows as they work towards helping those in need.
One possible plotline could be Naruto finding himself in the Family Guy universe and being pursued by some of the female characters there, creating a comical and chaotic harem situation. For example, Lois might be intrigued by Naruto's ninja skills and his different worldliness, leading to some humorous interactions.
One possible storyline could be Naruto running away from the village. Since his family ignores him, he might feel like there's no place for him there. He could then go on a journey to find a place where he is accepted. Another storyline could be Naruto becoming a sort of lone wolf within the village. He trains in secret, away from everyone, and emerges as a powerful but mysterious figure. He might also start to form alliances with outcasts in the village who also feel ignored.
There are also fanfics where Tsunade helps Naruto unlock a new form of his power through her knowledge of the old ninja ways. She might take him on a journey to discover ancient scrolls or training grounds. Along this journey, they face various challenges together, and Naruto learns a great deal from Tsunade about the history and traditions of the ninja world, all in a very family - friendly and exciting way.
Another reason could be jealousy. If Dark Naruto has certain unique abilities or powers that set him apart from the rest of the family, they may be jealous and rather than embrace him, they choose to ignore him. This would be a rather petty reason, but in the complex world of fanfiction, it's a possibility.
