His personality would probably be more cold and calculating. Danzo's influence would make Naruto less likely to trust others easily.
If Naruto was trained by Danzo in fanfiction, his personality would undergo a significant transformation. Danzo is a very strict and somewhat paranoid figure. Naruto, under his tutelage, would likely become more cautious and less impulsive. His sense of justice might become more skewed towards Danzo's view of the village's interests. He may no longer have that unwavering belief in everyone's potential for good. Instead, he might view the world through a more cynical lens, always suspecting ulterior motives in others. His usual enthusiasm and determination might still be there but would be channeled in a more controlled and perhaps less empathetic way. For instance, he might be quicker to use force or manipulation to achieve his goals, rather than trying to reach out and understand his opponents as he usually does.
