What could be the reasons behind the family ignoring Dark Naruto in the 'dark naruto is ignored by his family fanfiction'?

It could also be due to differences in values. If Dark Naruto had different beliefs about power, friendship, or loyalty compared to his family, and they constantly clashed over these, it might lead to his hatred. For instance, if his family adhered strictly to Konoha's traditional values but he saw them as restrictive.

Dark Naruto might become more rebellious. He could start to distance himself further from his family and focus on building his own power. Maybe he'll find allies outside of his family who understand and support him.

In the fanfiction, there could be a family curse or some sort of obligation that forces his family to keep their distance from Naruto. They might believe that by ignoring him, they are protecting him or the family as a whole. For instance, if there is a dark force targeting Naruto, they might think that acting as if they don't care will keep him safe from that threat.

One possible reason could be a sense of betrayal. Maybe he felt abandoned or mistreated by Konoha in some way. For example, if he was shunned because of the power within him that others feared.

Perhaps in the fanfiction, Dark Naruto has been betrayed. It could be that someone he trusted deeply, like a mentor or a close friend, turned on him. This act of betrayal could make him lose faith in humanity and lead to his hatred for everyone. He might think that if one person can betray him, then anyone can, so he hates them all without distinction.

One possible reason could be jealousy within the family. If Naruto is getting a lot of attention from others in the harem aspect, his family might feel jealous or threatened. They could then choose to ignore him as a way of expressing their discomfort.

Another reason might be related to Naruto's own insecurities. He might not believe that someone like Hinata could truly be interested in him. So, instead of facing the possibility of rejection or the complexity of a relationship, he simply ignores her and focuses on other aspects of his life like his ninja training and his friends.

It might be due to the fanbase loyalty. Fairy Tail fans are really into their own world and characters. They might not want to introduce Naruto elements as they feel it could disrupt the original charm of Fairy Tail. Also, the art styles are different. Naruto has a more traditional Japanese anime look, and Fairy Tail has its own style. This visual difference could be a reason for the lack of crossovers in fanfictions.

One possible reason could be that Dark Naruto might see Kushina as a symbol of the world that rejected him. Since she was an important part of Naruto's family and the village, and Dark Naruto represents Naruto's negative emotions, he could resent her for the life he didn't have. He may feel that if Kushina had been there for him more (in his twisted view), he wouldn't have turned into this dark version.

One possible reason could be feeling neglected. Maybe his family was always preoccupied with other matters, like protecting the village, and didn't give him enough attention. So he grew to resent them.
