Naruto's character would change in multiple ways. Firstly, his confidence might turn into over - confidence bordering on arrogance. Since he is now a God of Destruction, he may think he knows best and not listen to others' advice as he used to. Secondly, his relationships would be strained. His friends might be afraid of him, and he might not know how to handle that. His self - sacrifice nature could be replaced by a more self - centered attitude as he tries to figure out his new role. And finally, his view of justice would be warped. Instead of the traditional idea of protecting the weak, he might start to think that destruction can also lead to a new form of order, which is a complete departure from his original character.
He would likely become more detached from his emotions. As the God of Destruction, Naruto might view things from a more 'big picture' perspective that doesn't take into account individual lives as much. His once - bright and friendly personality could be overshadowed by a more stoic and indifferent one.
He would become more isolated. As the God of Destruction, people would be afraid of him, and his friends might not understand him anymore. Naruto is used to being the hero, but in this new role, he'd be seen as a threat.
Naruto's relationships would change drastically. His friends might be in awe of him or even a bit afraid. He would no longer be just the goofy ninja they knew. He would have a new level of power and responsibility. And his enemies would be much more cautious around him, knowing that he has the might of a Greek god behind him. His entire personality would shift to adapt to this new status, while still retaining some of his core ninja values.
Naruto's character would likely become more patient. Dealing with Pokemon, which are different from his usual ninja foes, would require a different approach. He would have to understand their behaviors and needs, which would make him more patient and empathetic. Also, his leadership skills from the Naruto series would be enhanced as he might lead groups of Pokemon trainers in this fanfiction world.
His relationships with his friends would become more complex. For example, Sasuke might be jealous or in awe of Naruto's new power. Sakura might see him as more of a distant figure, someone she can't fully understand anymore. And his old teachers like Kakashi would be in a position of having to respect Naruto's new status while still trying to guide him in some ways.
Naruto's character development would be complex. He would gain a new sense of purpose. In his ninja world, his goal was to protect his village and become Hokage. Now, he has to protect an entire universe. This would force him to grow in ways he never expected. He would have to learn about different cultures and species in Universe 7. His values would also be tested. For instance, he might have to make tough decisions about sacrificing one planet to save the whole universe, which would be a major shift from his usual 'never - give - up - on - anyone' attitude.
If Naruto were an ancient god in fanfiction, his relationships would be transformed. His relationship with his teacher, Iruka, would shift from a mentor - student bond to something more like a prophet - deity relationship. Iruka might feel a great sense of pride but also a bit of unease in Naruto's presence. His friends in Team 7 would have to adjust. Naruto's new powers and status would make them reevaluate their own positions. They might feel a bit overshadowed, but also protected. And as for his enemies, they would be forced to either submit or plot more deviously against him, knowing that he is now an ancient god with powers they can't fully comprehend.
His relationship with Sasuke would likely be very different. Sasuke might be more in awe of Naruto, but also feel a greater sense of distance. They would no longer be just rivals, but there could be a new power dynamic where Naruto is in a much higher position.
His relationships would change a great deal. With Sasuke, there might be a new level of respect. Sasuke would see Naruto in a whole new light, not just as a rival but as someone truly powerful. His friends like Sakura and Kakashi would be more in awe of him. They might feel a bit of distance at first, but Naruto would try to bridge that gap. His enemies would be either terrified or would try to use his new status to their advantage.
If Percy became the God of Destruction in the fanfiction, his relationships would become very complex. With his enemies, they would be even more terrified of him. However, some of his former enemies might also try to ally with him, seeing his power as a means to their own ends. His relationship with his mother would also change. She would be worried about her son, but also proud of his new - found status in a way. Percy would have to navigate these new relationship dynamics carefully.
His relationship with Annabeth would become more complex. Annabeth might be worried about Percy's new power getting out of control. She would try to help him find a balance, which could lead to some arguments but also deeper understanding.
