His confidence would probably soar. Knowing he has his parents, who are likely strong ninjas, supporting him would make him feel more secure. He might become a bit less reckless as he now has people who care about him deeply and he wouldn't want to worry them.
Well, Naruto has always been a very determined and kind - hearted person. If he finds out his parents are alive, his kindness might be even more pronounced. He would be so grateful to have a family again that he'd want to spread that love and joy to others. His determination could shift a bit too. Instead of just being determined to prove himself, he'd be determined to make his parents proud. He might also be a bit more patient, as he'd be learning about his family history and his place in it from his parents.
Naruto's personality could become more mature. He has always been a bit of a prankster, but with his parents alive, he might feel the need to be more responsible. He'd also be more likely to show his vulnerable side, as he now has his parents to turn to. He might not have to put on such a tough exterior all the time.
Naruto's personality could become more confident and stable. With a mother figure in his life, he would have someone to turn to for emotional support. He might not be as impulsive as he was before because Kushina could give him advice based on her own experiences. For example, when dealing with conflicts in the village or with other ninja, he would think twice instead of jumping into action right away.
Well, it would be a huge shock for Naruto. In the original, he had no idea about his family. If they were alive, Naruto might not be so eager to gain recognition from the village. His family could teach him things he didn't learn from the academy or from Jiraiya. And his family might have secrets or powers that could help him in battles. Maybe his father could teach him some advanced space - time jutsu. It would also add a new layer of family drama to the story, like dealing with family expectations and reuniting with long - lost relatives.
In such a fanfiction, Harry would likely be in shock. His world view has been centered around their deaths for so long. He could be hesitant to trust this new reality. But once he does, he'd have a whole new support system. His parents could teach him magic they've learned in their 'hidden' years. This would make him even more powerful and give him a different standing among his peers.
Well, one thing that could happen is that Naruto would be overjoyed. He has always longed for a family, and to suddenly find out his parents are alive would be a dream come true. He'd probably have a million questions for them about his past, why they had to be away, and what their lives were like. And his relationship with his friends might change a bit too, as he now has this new family aspect to his life.
Well, for one, Harry would grow up in a loving family environment. He wouldn't have to live with the Dursleys. His magical education would likely start much earlier and be guided by his parents, especially James who was also a very talented wizard. His confidence and self - esteem would be much higher as he wouldn't have the emotional baggage of being an orphan.
The plot would change a great deal. For one, Harry wouldn't have to live with the Dursleys. He would grow up in a loving magical household. He'd be more confident and perhaps less of an underdog. His parents would be able to train him in magic from a young age, so he might be more advanced in his studies when he gets to Hogwarts. Also, the fight against Voldemort would be a family affair, with James and Lily Potter being key players in the battle against the Dark Lord.
His power level would likely increase significantly. If he wished for enhanced ninja abilities, he could become even stronger than he already is. This would make him an even more formidable opponent in battles.
Naruto would also be more reserved in expressing his emotions. The Naras tend to keep their feelings close to the vest. So, he might not be as openly enthusiastic or angry as he was before. However, his core values of loyalty and protecting his friends would still remain, just expressed in a more Nara - like, understated way.
His personality might become more withdrawn. As a lich, Naruto could be feared by others, and this might make him more hesitant to interact with people. He was always so outgoing before, but now he might keep to himself more.
Naruto may also become more solitary. Sparda often fought alone, and Naruto, influenced by this, might start to distance himself from his friends at first. However, he would still have that underlying loyalty and would eventually find a way to balance his new - found independence with his relationships.
