Well, if we look at the 'Naruto gets his parents back fanfiction', Naruto's character development might take a different turn. Instead of relying solely on his friends and mentors like Iruka and Kakashi, he'd have his parents' direct guidance. His father, Minato, could train him in advanced ninjutsu. His mother, Kushina, could give him all the motherly love and care he was deprived of. This would likely make Naruto more confident and perhaps a bit more relaxed as he wouldn't have that deep - seated longing for family anymore.
One possible start for the 'Naruto gets his parents back fanfiction' is that there is a discovery in an ancient scroll. The scroll contains a spell that can bring the dead back under certain conditions. Naruto, being the curious and determined ninja he is, decides to try it out. Or perhaps, in a different dimension, Naruto's parents are still alive and through some strange portal or rift, they are able to return to the Naruto world.
Hermione and Ron are usually quite common. Since they are Harry's best friends, they would be involved in the story when Harry's parents return. They might be curious about his parents, and also help Harry and his parents adjust to the current situation.
Well, one possible plot development could be that when Harry gets his parents back, they have to quickly adapt to the modern wizarding world. His parents were from an earlier time, so things like new spells and magical devices might be quite a shock for them.
In this type of fanfiction, Naruto could have a different attitude towards authority. As his parents are neglecting him, he might not have that natural respect for figures of power. He may question the village's system more. Also, his dreams of becoming Hokage could take on a new meaning. Instead of just seeking recognition, it could be a way for him to create a family - a village where no one is neglected like he was by his parents.
His emotional side would be deeply affected. He might be more guarded and less likely to show his true feelings easily. He would see the world in a more cynical way at first. But as he grows, he could use his experiences to become more empathetic towards others who are also alone or neglected. For instance, he could start reaching out to orphaned kids in the village. His journey to becoming Hokage would also be different. Instead of having the typical family - inspired motivation, it could be a way to rewrite the story of neglect in his own life and in the village.
Emotionally, Naruto would have to deal with a whole new set of family relationships. He grew up without his parents, and now having them back would be a huge adjustment. He might struggle to fit into a 'normal' family dynamic, and there could be some friction as they all get to know each other again.
In some fanfictions, Naruto might find a super - powerful jutsu or artifact. For example, he could discover a long - lost forbidden jutsu that has the power to bring the dead back to life. Or perhaps he stumbles upon a magical item during one of his adventures that is said to be able to revive the deceased.
On a personal level, Naruto would finally get the family he always wanted. But it might also bring some confusion and adjustment issues. His parents would be from a different time, and they'd need to adapt to the new world Naruto lives in. For example, they might be shocked by the new technology and the changes in ninja warfare.
He would probably be overjoyed. Harry has always longed for a connection with his parents. Getting their portraits would be like getting a part of them back. He might just stand there, staring at the portraits with a big smile on his face, unable to take his eyes off them.
