It could be a sign of his newfound shyness or self - consciousness. For example, if he has a new power or a different appearance, he might cover his face until he gets used to it. Suppose he has a new form that he doesn't fully understand yet. In that case, covering his face can be a way to deal with the internal conflict of this change.
Maybe he's trying to hide his identity for a secret mission. In some fanfictions, Naruto might be undercover, and covering his face is a simple way to avoid being recognized.
Perhaps he's trying to protect himself from some kind of danger. There could be an enemy who is looking for him and by covering his face, he can avoid being detected easily. It could also be a part of a new jutsu or power he has discovered where covering his face is necessary for its activation or control.
In some fanfictions, Naruto might be made to hate his mother because of a misinterpreted prophecy or a false belief that she abandoned him. Maybe the author wants to create a more complex and angsty story line for Naruto.
It's a complex plot twist. Joker does it to show his complete descent into madness and break away from his usual image.
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.
Some fanfictions like to take a non - traditional approach. Naruto may hate his mom because the fanfic writer is trying to show how a character can be shaped by false perceptions. For example, if the mom was from a different clan that had some bad blood with the Hidden Leaf, and Naruto hears only one - sided stories, he could develop hatred. Also, it could be a way to explore the theme of forgiveness later on in the story, where Naruto has to overcome this false hatred when he discovers the truth.
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.
Well, in some fanfictions, Naruto might cut his hair as a symbol of a new beginning. Maybe he's been through a tough time and wants to change his look to show that he's growing and evolving.
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 he is on a secret mission and doesn't want to be recognized. He might be infiltrating an enemy organization or spying on someone. Another reason could be that he has some new power or mark on his face that he wants to keep hidden until he fully understands or masters it.
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.
