He could start by having an honest conversation with his friends. Explain his side of the story clearly. For example, if it was a misunderstanding, he can show evidence to clear his name.
Naruto could try to prove himself through his actions. If his friends think he's become too power - hungry, he can use his power for the good of the group. He might also sacrifice something valuable to show his loyalty to his friends.
One possible reason could be envy. If Naruto suddenly gains a great deal of power or attention in the fanfiction, his friends might feel left out or jealous. Another reason could be a misunderstanding. Maybe Naruto is framed for something he didn't do, and his friends believe the false accusations without giving him a chance to explain. Also, in some fanfiction, a change in Naruto's personality, like becoming overly aggressive or secretive, could lead to his friends growing to dislike him.
He might try to prove himself. Naruto has always been a determined character. So he would likely strive to show his family that they are wrong about him. He could do this by achieving great things in the ninja world, like mastering new jutsus or completing difficult missions.
In some fanfictions, Naruto might be hated by his friends due to a misunderstanding. For example, if there's a false rumor spread about him being a traitor. Another reason could be his sudden increase in power that makes his friends jealous. Maybe he accidentally harms one of them during a training session and they hold a grudge.
Naruto could try to communicate. He could sit down with his family members and try to understand why they hate him and also explain his side of the story.
At first, Naruto might be really confused. He's used to thinking of his friends as his support system, so when they turn on him, he doesn't understand why. He'll probably try to talk to them, to ask what he did wrong. If they don't listen, he could become really sad and withdrawn. Maybe he'll start training even harder, using the pain of being rejected by his friends as motivation to become stronger.
In fanfiction, Naruto's shyness could be overcome by him facing his fears directly. He could be put in situations where he has to interact with strangers or perform in front of others. Each time he does this, he learns a bit more about himself and how to control his shyness. For instance, if he is forced to give a speech in the Hidden Leaf Village, at first he would be extremely nervous, but as he continues, he realizes that the more he prepares and the more he focuses on the message rather than the people watching, the easier it gets.
He could start by finding true friends who accept him unconditionally. For example, his friends in Team 7 might help him realize his self - worth. Another way is through self - discovery. Naruto could focus on his ninja training and find that he is capable of great things on his own, which would boost his confidence.
It's not overly common, but it does exist. A lot of Naruto fanfiction tends to focus on other aspects like his relationships with his friends or his growth as a ninja. However, the concept of his parents hating him can offer a unique and often darker take on the character. Writers may use this to show a more jaded Naruto, one who has to overcome not just the hatred of the village but also from his own family.
Harry can focus on self - improvement. He can pour his energy into his studies, become an expert in different branches of magic. This would not only boost his confidence but also make him more independent. For instance, if he masters advanced potions making, he'll feel a sense of accomplishment on his own.
He could start by having a positive experience with a kind doctor. For example, a doctor who takes the time to explain things to him gently and shows real concern for his well - being.
