In fanfiction, Naruto might release his pain and hurt through intense training. He could pour all his emotional distress into becoming stronger, pushing his physical limits as a way to distract himself from the pain inside.
Another possibility is that Naruto releases his pain and hurt by helping others in the fanfiction. He has always been someone who cares about others. By focusing on the problems of villagers or other ninja, he could find a sense of purpose that overshadows his own pain. He might see their struggles and realize that his pain is not the only thing in the world, and in the process of making a difference in their lives, he unburdens himself.
In some fanfiction scenarios, Voldemort could expose Narcissa's secrets. If she has any hidden secrets, like her true feelings towards the Dark Lord or her family's real intentions, he could reveal them to other Death Eaters. This would lead to her being ostracized or even facing more severe consequences. Also, he could use her as a human shield in a battle situation, which would put her life in immediate danger and also make her feel used and disposable.
Iruka -sensei could also be a key figure. He has a deep connection with Naruto from the start. In fanfiction, he might sit Naruto down and have heart - to - heart conversations, guiding Naruto through his pain and helping him come to terms with it. And of course, Hinata. Her love and gentle support could give Naruto the strength and comfort he needs to let go of his pain.
One reason is that some fanfiction authors may lack a deep understanding of Naruto's character. They might write things that are completely contrary to his values and personality just for the sake of creating a 'unique' story. For example, Naruto is known for his positive attitude and strong will, but in some fanfictions, he could be depicted as a negative or spineless character.
One possible cause could be his sense of failure. Naruto always wants to protect his friends and village, so if he fails in a mission or is unable to save someone, it can cause him great pain.
Well, Naruto could also seek support from his friends like Sasuke or Sakura. They have been through a lot together, and they might be able to offer him some comfort and advice on how to handle this difficult situation. Since Naruto values his friendships highly, their words could have a big impact on him.
It could be due to Sakura's feelings for Sasuke. If she's overly focused on Sasuke and Naruto gets in the way of her plans regarding Sasuke in some way, she might lash out and hurt Naruto without really meaning to cause serious harm.
One way is through brute force. Houndoom could be extremely powerful in the fanfiction and simply overpower Naruto's attackers. For instance, if there are some assassins after Naruto, Houndoom could charge at them and knock them out with its physical strength.
In some fanfictions, Naruto could gain the ability to fly as a result of a forbidden jutsu. This jutsu might be so powerful that it not only gives him flight but also enhances his other abilities. For instance, he could be forced to use this jutsu in a life - or - death situation against a very powerful enemy. Also, he could fly if he absorbs some kind of special energy or power - up from an ancient relic. This power - up could transform his body in a way that allows him to fly, like growing wings made of pure chakra.
One way is by using his Sage Mode. Naruto in Sage Mode has enhanced senses and chakra control. He could use these advantages to refine the Hiraishin. For example, he might be able to make more precise teleportations or detect potential threats at the destination of the Hiraishin more accurately.
Naruto could use Ki to enhance his sensory abilities. In the Naruto universe, he already has good sensory skills with his chakra. But by adding Ki into the mix, he could expand his range of detection even further. He could sense enemies from much greater distances or even detect hidden traps or secrets in the environment around him.
