One way could be through his diplomatic skills. Harry might be able to negotiate with the goblins in a very fair and respectful way. He could understand their concerns and offer solutions that benefit both parties. This would make the goblins see him as an intelligent and reliable person.
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.
Maybe he got some kind of curse. In the Naruto universe, there are all sorts of dark magic and curses. If he was cursed, it could make him withdrawn and cause him to ignore everyone.
It could be about a boy with some extraordinary physical feature (big penis being a very odd and inappropriate way to describe in a normal context here) doing something amazing at the beach like rescuing a drowning person, which impresses everyone there.
One possible reason could be a powerful genjutsu cast over the village. Maybe an enemy ninja with strong illusionary powers managed to make everyone forget Naruto. It could also be due to some sort of curse. For example, a dark curse was placed on Naruto that made people's memories of him fade away gradually.
One possible reason could be that Naruto has seen or experienced something that makes him distrust or fear those around him. Maybe he has discovered a dark secret about the village or his friends that has shaken his beliefs.
It could also be that Naruto has had some sort of revelation about himself or the ninja world. He might have realized that the relationships he has been in were holding him back in some way. Maybe he wants to focus on self - improvement and growth, and he believes that being alone is the best way to do that. He could be trying to find his true self without the influence of others.
One common scenario is at Hogwarts. Maybe during a school project or competition, Harry's unique approach and determination lead to success, and Zabini, being a spectator, is impressed. For instance, in a Potions competition, Harry might come up with a brilliant solution to a difficult potion - making problem.
Maybe in that fanfiction, Naruto's over - eagerness to be recognized could be misconstrued. His loud and boisterous nature might annoy people. For example, if he constantly interrupted others or pushed his ideas too hard without considering others' feelings, it could lead to dislike.
Well, Naruto has a huge and rich world. The fanfiction allows fans to explore different aspects that the original might not have fully delved into. For example, they can create new relationships between characters or imagine different plotlines for their favorite characters. It gives fans a chance to be creative and put their own spin on the Naruto universe.
