It could be that in this fanfiction's universe, Naruto's family has some sort of dark connection or alliance that goes against Naruto's new moral code as a godlike being. He may see their actions as unforgivable and as a result, choose to disown them in order to uphold his own sense of justice and righteousness.
One reason could be that Naruto has been through a lot of hardships related to his family in the fanfic. Maybe they didn't support his growth to this godlike state, or they tried to use his power for their own gain. For example, if his family had always been jealous of his potential and when he finally reached this ultimate power, he realized their true nature and decided to cut ties.
In this kind of fanfiction, Naruto might have reached a god - like state where he believes his family's values and traditions are no longer relevant to him. He could be on a journey to create his own identity independent of his family, perhaps after experiencing some sort of betrayal from within the family that only he, in his newfound power, is aware of.
One possible reason could be that his newfound 'godlike' powers make his family feel estranged. They might not understand his sudden transformation and the magnitude of his power, which creates a sense of fear or discomfort, leading them to ignore him.
One possible aspect could be that Naruto's family's neglect in this fanfiction might lead to his 'dark godlike' transformation. It could be a way for him to cope with the lack of love and support from his family. He might develop a more independent and self - reliant nature, relying only on his own power which grows to godlike levels.
Well, in some fanfictions, a 'godlike' Naruto might become overconfident. His newfound power could make him act without considering his family's values or traditions. For example, he might use extreme and unethical means to achieve his goals, which his family would not approve of, thus dishonoring them.
His father might be extremely disappointed. As a former Hokage, he would have expected Naruto to uphold the family's honor. His mother would probably be heartbroken, having always believed in Naruto's good nature.
He might feel very sad and lonely at first. Naruto has always craved family love and acceptance, so being ignored by them would be a huge blow.
Power and its implications. Since Naruto is godlike, it often explores how that power affects his family life, like whether it brings more danger or security.
One possible plot could be that Naruto has a godlike power that scares his family. His family, being normal shinobi in comparison, might be intimidated by his power. They don't know how to approach him anymore. Naruto, on the other hand, longs for their acceptance and love like before. He tries to control his power around them, but they still shy away, causing Naruto a great deal of emotional pain.
In this fanfiction, perhaps Naruto's family abandons him because they believe he's a danger due to his godlike abilities. He might start as a broken character, but as the story progresses, he could use his powers to protect those who accept him, like his friends in Konoha. He would have to overcome the emotional trauma of being abandoned and rise above it all.
Naruto could develop a sense of independence. Since his family neglects him, he has to rely on himself. This might make him more self - assured and less likely to seek approval from others, especially his family.
