He might also be hiding his appearance to go undercover. Naruto could be on a mission that requires him to blend in with a group that doesn't like or trust the regular Naruto. So, by changing his look, he can get closer to the target or gather information without arousing suspicion.
Perhaps Naruto is trying to distance himself from his fame. He has become such a well - known figure in the ninja world, and sometimes that fame can be a burden. Hiding his appearance gives him a chance to just be an ordinary ninja again, at least for a while, and experience things without the constant attention that comes with being 'Naruto Uzumaki'.
One possible reason could be for protection. Maybe there are threats out there targeting him, so by hiding his appearance, he can move around more freely without being recognized. For example, if there are rogue ninja who want to take revenge on him for past battles, hiding his face would make it difficult for them to track him down.
To gain an advantage. Just like in the original series where he often used surprise to his benefit. In fanfiction, hiding his power allows him to do the same. He can catch his opponents off - guard.
Naruto might hide his feelings because he doesn't want to burden others. He has been through a lot in his life, like being an orphan and facing discrimination in the village. He may think that sharing his negative feelings, such as loneliness or self - doubt, will make others worry about him. So, he chooses to keep them to himself and always show a positive, determined side to the people around him.
One possible reason could be that his eyes hold a special power that he doesn't want others to discover easily. For example, it might be a new type of Sharingan or a unique ability related to his Uzumaki heritage that he needs to keep secret to protect himself or those around him.
Maybe he wants to surprise his opponents in battles. He could be waiting for the perfect moment to reveal his full power and turn the tables on his enemies.
One possible reason could be that he doesn't want others to pity him. Naruto has always been a proud and strong - willed character. His scars might be a reminder of painful past experiences, and he prefers to deal with them privately rather than showing vulnerability to others.
He could use a simple disguise like a cloak with a hood. This is a classic way to hide one's face and body shape. Just like in many stories, a large, dark cloak can make it hard for people to see who is underneath. He could also keep the hood up to shadow his face.
Well, in fanfictions, often the plot takes a different turn. Naruto might hide from his family because there could be some sort of misunderstanding. For example, there could be false rumors about him being involved in something bad. And he might think that his family would believe those rumors without giving him a chance to explain. So, to avoid the immediate confrontation and judgment, he chooses to hide.
Another reason could be related to his personal growth. He might be trying to master the power of the eye in private. Naruto has always been one to face challenges alone at first. By hiding his eye, he can focus on understanding and using its power without distractions or the pressure of others' expectations.
It could also be part of a strategic move. By hiding his bloodline, he can surprise his opponents in battle. They would underestimate him based on not knowing about his true powers, and then he could turn the tables on them when the time is right. This gives him an edge in combat situations.
He might use some special jutsu or seals. For example, he could use a sealing technique to suppress the signs of his bloodline. This way, others wouldn't be able to detect it through normal means like sensing chakra.
