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.
His friends would be hurt. They are used to the warm - hearted Naruto, and his coldness would make them feel rejected and confused. They might try to reach out to him but be constantly rebuffed.
Perhaps he is trying to hide his true self. He may have a side of him that he doesn't want others to discover, like some special abilities or a different origin. So, being cold to everyone helps him keep his secrets and avoid getting too close to people who might figure him out.
It could be due to a personal loss that has hit him really hard. Maybe he lost someone very close to him, like Jiraiya all over again, but this time it has broken him in a way that he shuts everyone out. He might also be under the influence of a new power that he doesn't fully understand yet, and this power is affecting his emotions, making him cold as a side - effect until he learns to control it.
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.
It could end with Naruto finding true friends who accept him for who he is, and he starts a new life away from the place that betrayed him.
Well, if Naruto is godlike and betrayed by everyone in a fanfic, it could start with the villagers' fear of his newfound power. They might think he's a threat and turn on him. Naruto, being so powerful, could initially be in disbelief. But as the betrayal sinks in, he might decide to leave the Hidden Leaf. He could then wander the world, trying to figure out his place in it while also being cautious of those who might want to take advantage of his power or finish him off.
One consequence could be an imbalance in the world's population. There might be too many people for the existing resources, leading to shortages of food, water, and living space.
Yes, there are some. You can try searching on popular fanfiction platforms like Archive of Our Own. However, the quality can vary greatly. Some may have really creative storylines that explore unique relationships and character developments within the Naruto universe in a yaoi context.
The 'cold' aspect could add an interesting layer to Naruto's character. Maybe he's more aloof or has a different kind of power that gives off a cold vibe, like ice - based powers that are super strong. In fanfiction, this can lead to unique interactions with other characters. He could be seen as more of an enigma, which makes the story more engaging as readers try to figure him out.
Well, in some fanfictions, Naruto might use some super powerful jutsu that he either discovers or creates. Maybe it's a new form of the Rasengan combined with some sealing techniques. It could also be that he taps into some ancient power or makes a deal with some sort of god - like entity within the Naruto universe.
