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.
It could also be a sign of grief in some fanfictions. For example, if he loses someone close to him, he cuts his hair as a way of mourning, like in some cultures where people cut their hair when they're in deep sorrow.
One possible reason could be extreme stress or trauma. In some fanfictions, Naruto might go through a really tough battle or face a great loss that drains him both physically and mentally. This could potentially cause his hair to turn white, similar to how people in real life can get premature grey hair from high stress.
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.
The Joker cutting his face off is a symbolic act of completely letting go of any pretense of normalcy and embracing his insanity to the fullest. It's a shock tactic to terrorize and confuse his enemies.
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.
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.
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.
