Well, in fanfiction, anything can happen. Maybe it's some sort of magical or strange plot device. It could be that a powerful jutsu backfired and somehow Naruto was transformed or connected to the Juubi in a way that made him (in this fic) the'mother'.
The Juubi could save Naruto by sharing its knowledge. In the fanfiction, the Juubi might be an ancient and wise being. It could communicate with Naruto on a spiritual level and give him insights or techniques that help him out of a tough situation. For instance, it could show Naruto a new way to use his existing jutsu more effectively, or it could reveal a secret about the enemy that Naruto is facing, allowing him to strategize better and ultimately be saved from defeat.
Maybe through some sort of ancient ritual. In the Naruto universe, there are often powerful and mysterious rituals. It could be that Naruto discovers an old scroll or is guided by a sage to perform a ritual that allows him to bond with the Juubi.
Well, it could be that Naruto's strong will and his connection to all the other tailed beasts play a role. Since he has befriended the other tailed beasts, their combined energy or some sort of spiritual link might attract the power of the Juubi. For example, in some fanfic concepts, the tailed beasts' collective consciousness decides to merge their powers with Naruto, which includes the Juubi's power as the ultimate form of chakra.
The power dynamics would shift significantly. Firstly, Naruto's influence over the Juubi would likely give him control over a vast amount of chakra, more than he already has. This could lead to him being able to easily overpower most opponents. Allies might rely on him even more, and enemies would be more cautious. For example, villages that were once rivals might be more inclined to form alliances with Konoha because of Naruto's new position. Also, the tailed beasts' relationships with Naruto would become more complex as he is now linked to their origin in a very different way.
Yes, in some fanfictions, Naruto can be depicted as having the Juubi. Fanfiction writers often like to create unique scenarios where they can explore different power-ups for their favorite characters, and giving Naruto the Juubi is one such creative take.
One implication could be a change in Naruto's relationships. He might have a more nurturing or protective stance towards the Juubi, which is very different from the usual combat - based relationship in the original series.
Hinata supports Naruto by being his emotional anchor. When facing the Juubi, Naruto can get caught up in the chaos and danger, but Hinata is there to remind him of his humanity and the things he's fighting for. For example, with a simple look or a kind word, she can calm him down in the heat of battle.
Well, it could have a huge impact. Maybe his new power as the Juubi gives him the ability to control time in some way during the time - travel. For example, he might be able to reverse or speed up certain events more easily than he could without that power.
One way could be through some kind of power - up. For instance, if Naruto discovers a new form or a hidden power that gives him the same level of strength as the Juubi. Maybe he merges with some other powerful entity or unlocks a secret jutsu that boosts his power to that of the Juubi.
Yes, in some fanfictions, Naruto can be depicted as the Juubi. Fanfiction writers often take creative liberties and come up with unique and unexpected concepts like this. It adds an interesting twist to the Naruto universe and can lead to some really exciting and different storylines.
