Well, at first, people around him would be very confused and try to reach out. But Naruto would just push them away. Then, his former friends might start to get frustrated with his coldness. Some might even turn against him thinking he has changed for the worse.
As the story goes on, Naruto might start to form new alliances with unexpected characters. Since he is cold to his old friends, he could find common ground with those who are also outcasts or have a different view of the world. This could lead to a whole new set of adventures and conflicts.
The story might progress with his friends and family trying to come to terms with his 'death'. Some might go into seclusion, like Hinata maybe. Others could start investigations to find out what really happened.
The story could start with Naruto suddenly finding himself in a giant form. Then he has to quickly figure out how to move without causing too much destruction. As he gets used to his new body, he might start using it to protect the village from threats that normal - sized ninja couldn't handle.
The story could progress with Naruto being shunned by those he once called friends. He might then be on a journey to find a way to reverse his transformation. Along the way, he could encounter other characters from different universes who either help or hinder his quest.
In a fanfiction where Naruto becomes Darth Raven, the story's progression would be full of twists. Naruto, now with his new identity, could start to influence the political landscape of the ninja world. He might use his newfound dark powers to manipulate leaders or disrupt existing power structures. His friends, especially those closest to him, would be torn between loyalty and the need to stop his potentially destructive actions. The story could also explore how Naruto's transformation affects the balance of power between the different ninja villages. For example, some villages might see an opportunity to use his new power for their own gain, while others would be desperate to put an end to his reign of darkness. Additionally, Naruto's internal struggle with his new self could be a central theme, with flashbacks to his old self and the values he once held, creating a complex and engaging narrative.
It could be that his new 'godlike' power has isolated him. People might be either in awe or afraid of him, and he may feel that he can't be close to others as before. So he acts coldly as a defense mechanism.
One possible reason could be a great betrayal. Maybe he discovers that someone he deeply trusted, like a close friend or a respected mentor, has been using him all along. This would shatter his trust and make him withdraw from people, thus becoming cold.
His relationships would become very different. Since Naruto is usually so friendly and outgoing, this coldness would be a shock. His friends like Shikamaru, who respects Naruto's normal nature, would be put off. They might think he's going through something really bad, but his lack of communication due to the coldness would make it hard for them to offer help. As a result, his friendships could start to crumble.
Well, his friends would be really confused at first. They're used to Naruto's warm and energetic self. Sasuke might be a bit more standoffish in return, thinking Naruto has changed for the worse. Sakura would probably try to get to the bottom of it, constantly pestering Naruto to find out what's wrong. His other friends like Shikamaru might just give him space at first, waiting for him to come around on his own.
Well, it might start with Naruto feeling weak and tired more often. His friends would notice his decline but he would try to hide it at first. As the story goes on, he would start losing his ability to perform jutsus as effectively.
Well, in some versions, it might start with Team 7 being shocked at first. They may initially doubt Naruto's ability to be in ANBU because they still see him as the goofy Naruto they've always known. But as they see him in action, they start to respect his new role more. Maybe Naruto has to keep some secrets from them initially which causes some tension within the team, but eventually, they come to accept and support his position in ANBU.
