In a fanfiction scenario where Minato and Kushina disown Naruto, his character development would be severely affected. Naruto is a character who thrives on love and the idea of family, as we see in the original series. Without that from his parents, he might develop a much darker side. He could be filled with anger and resentment towards them, which could fuel his actions. His relationships with others would also change. He might be hesitant to form close bonds, fearing that they too could abandon him. This would be a completely different Naruto from the one we know, and his journey would be one of self - discovery in a much harsher and lonelier way.
If Minato and Kushina disown Naruto in fanfiction, Naruto's character might develop in a very different way. He may grow up with a sense of abandonment that shapes his entire personality. He could become extremely independent but also very lonely. His idea of family would be completely distorted. He might even start to view the concept of 'home' as something he doesn't have or need. This could also make him more empathetic towards other outcasts, as he himself has been cast out by his own parents.
