He might also lose some of his self - control. Rage can often make a person act without thinking, and Naruto in this fanfic would be no different. This could put him in dangerous situations where he's not fully aware of the risks, like running into a trap because his rage blinded him to the signs.
On the positive side, being fueled by rage could make him a more powerful ninja. However, this power might come at the cost of his mental and emotional well - being. He could become more isolated as his rage -fueled behavior might push away those who care about him. In the long run, if he doesn't learn to control his rage, it could lead to his downfall, both as a ninja and as a person.
Well, in such a fanfic, Naruto's rage might manifest as a sudden burst of power during battles. For example, when facing a strong enemy, his anger could make his attacks more intense and less controlled. He might also be more reckless in his actions, not thinking about the consequences as much because the rage is clouding his judgment.
One consequence could be a change in his relationships. For instance, his bond with Sasuke might be seen in a new light as it could be related to the Indra - Asura cycle. Another consequence is that his power might be explained in a different way, perhaps as an inheritance from Indra.
Naruto could try to change Konoha from the outside. He might form an alliance with other villages or groups who share his views on how a village should be run, and then use their combined influence to force Konoha to make changes.
In a modern fanfic, if Naruto is hated by his family, it could change his entire life trajectory. He may be forced to leave his home earlier than in the original story. This would expose him to more danger at a younger age. His relationships with other characters would also be affected. For instance, his relationship with his teachers might become more complicated as they try to navigate the situation. Additionally, Naruto's view of the world could become more cynical, but he could also strive to create a new family of sorts among his friends, which would be a significant aspect of his character development.
Well, there could be a 'Naruto Rage Fanfic' where Naruto is enraged by the constant discrimination against the Jinchuriki. He decides to take a stand and train in secret to become so powerful that no one can ever look down on him or other Jinchuriki again. This could lead to epic battles and new alliances as he tries to change the shinobi world's view.
Well, if Naruto is an ancient demon in fanfiction, it could lead to a change in his power dynamics. He might have more uncontrollable and dangerous powers. His place in the ninja world could be completely redefined. People might either fear him or try to use him for their own gains. His moral compass could also be affected as the nature of being a demon might bring out more primal instincts. And his relationships with characters like Sasuke and Sakura would likely be put to the test as they deal with this new version of Naruto.
Perhaps Naruto's relationship with the other characters changes. Some might be wary of him now that he has a connection with the Juubi. On the other hand, some might see him as an even greater hero for surviving with the help of such a powerful entity. Also, Naruto might have a new sense of purpose. He could feel obligated to use the newfound power or knowledge from the Juubi to protect the village in a different way, or to seek a greater understanding of the Juubi's origin and the secrets it holds.
In some fanfictions, Kaguya being sealed might lead to new mysteries emerging. For example, there could be hidden secrets or powers that were associated with her that now start to surface. This could draw in new characters or lead to new adventures for the existing ones. Maybe some of Kaguya's leftover chakra starts to influence certain events or people in unexpected ways.
One consequence could be that Naruto has some strange side - effects. Since Orochimaru's methods are often unorthodox, Naruto might have trouble controlling his chakra properly. For example, his chakra could be tainted with some of Orochimaru's dark chakra, making his jutsu less stable.
In terms of the story's plot, it could lead to Naruto trying to redeem himself in Hinata's eyes. This could involve him going on dangerous quests or changing his ways. It also might make Naruto more isolated as he loses one of the people who used to care about him, which could in turn lead to a change in his relationships with other characters like Sasuke or Sakura.
