Most Naruto fanfics tend to focus on his adventures, his relationships in a positive way, like his bond with Sasuke or his training with Kakashi. The idea of Naruto becoming a pervert is quite out of the ordinary for the Naruto - themed fanfic world. It's not something that is typically explored in mainstream Naruto fan creations.
One idea could be that Naruto's greed is for power. He might see all the strong shinobi in the Hidden Leaf and start to envy their abilities, so he becomes greedy for more power. He could start seeking out forbidden jutsu or training methods that are considered dangerous.
On a broader scale, Naruto's achievement as a Chunin could affect the relationships between the Hidden Leaf and other ninja villages. Other villages might view the Hidden Leaf as even more powerful or might be more cautious in their interactions with it. His new rank could also open up opportunities for diplomatic missions or alliances that weren't possible before.
I think the whole of Team 7 would be behind him. Sasuke, despite his past, would see Naruto's potential as a Hokage and support him in his own way, perhaps by helping to protect the village from external threats. Kakashi, as Naruto's former teacher, would also be there to guide him in the early days of his Hokage - ship.
In a 'naruto becomes a god fanfic', Naruto's allies could include not only his friends from Konoha but also some unexpected characters. For example, some of the tailed beasts that he has befriended over the years might become his allies in a more direct way. They could combine their powers with Naruto's new god - like abilities to face common threats. And perhaps some of the old ninja clans that have respected Naruto's power and his ideals would also side with him.
I think the whole of Team 7 would be in full support. Sasuke might return to the village and support Naruto as he sees Naruto's growth and leadership potential. Kakashi would also be there to guide Naruto as he steps into the role. Additionally, the people of Konoha who have seen Naruto grow from an outcast to a hero would be very likely to support him as their new Hokage.
If Naruto becomes a ghoul in a fanfic, he could potentially use his new powers in unique ways. His ninja skills combined with ghoul abilities like kagune would make him a very formidable fighter. Maybe he'd try to find a way to survive without harming innocent people, like finding alternative food sources or using his powers only against bad guys.
If Naruto becomes immortal in a fanfic, one consequence could be that he would outlive all his friends. He would have to watch them grow old and die, which would be really sad. He might also become a bit of an outcast as he no longer fits into the normal cycle of life. People might start to fear him or see him as something other than human.
Well, if Naruto goes evil in fanfic, it's a total game - changer. First, his relationships would crumble. Sakura and Sasuke would be devastated. His sensei like Kakashi would try to reason with him but probably fail. And his enemies would be thrilled. They could use his new - found 'evil' side to their advantage and cause more chaos in the ninja world.
In a fanfic scenario where Naruto becomes the Juubi, it's a game - changer. Firstly, his appearance would probably change significantly, maybe having some Juubi - like features. His speed, strength, and the range of his jutsu would increase exponentially. He could use the Juubi's power to heal the land that has been damaged by years of war. However, there would also be those who see him as a threat and try to stop him, believing that no one should possess such power. This would create a lot of conflict and drama in the fanfic.
