It's possible that Naruto awakens with a new mission or purpose. He might realize that there was a hidden plot behind his sealing. So, he sets out to uncover the truth. Along the way, he meets old friends who are both skeptical and supportive of his new - found self. He has to prove himself all over again, not just in terms of strength but also in terms of his intentions.
Another possibility is a character who has been corrupted by the same power that was used to seal Naruto. This character could see Naruto's awakening as a threat to their new - found power or status. For example, if the sealing was related to some ancient and dark chakra, a ninja who has been influenced by this chakra might oppose Naruto.
Well, Naruto's powers would likely be drastically altered. He might gain some of Jenova's abilities, like regeneration or the power to infect others with her cells. His personality could also change as he struggles to control this new, alien power within him. The other characters in the Naruto universe would be very suspicious and maybe even afraid of him.
In some fanfictions, if Naruto was sealed in the Shinju, it could lead to a major shift in the power balance. His friends might go on a desperate quest to free him. The ninja world could be plunged into chaos as his absence leaves a huge void in terms of power and leadership.
In such a fanfiction scenario, many things could occur. One possibility is that the world would be thrown into chaos as Naruto is a major force for stability. His friends might embark on a dangerous mission to rescue him. They would have to figure out the mechanism of the seal on the moon and find a way to break it. It could also lead to power struggles on Earth as various factions try to take advantage of Naruto's absence.
One possibility in such a fanfiction scenario is that Kushina's own chakra, which was already special as an Uzumaki, could have an impact on Naruto while he's sealed within her. It could either strengthen him in some ways or cause unforeseen consequences. Also, characters like Minato would have a different relationship with the situation. Instead of seeing Naruto as his son on the outside, he might be more focused on the presence of Naruto within Kushina, which could change how he approaches protecting his family and the village.
Imagine Harry Potter sealed in Naruto fanfiction. Firstly, his appearance would be quite out of place. His robes and wand would draw a lot of attention. He might be imprisoned or studied at first. His ability to apparate could be seen as a form of high - level space - time ninjutsu. However, his lack of understanding of the ninja code could get him into trouble. He'd have to adapt to the different cultures of the ninja villages, like Konoha's values, and find a way to use his magic in harmony with the existing power structures, if he wants to avoid being constantly on the run or used as a tool.
In fanfiction, if Juubi Naruto was sealed in him, he might gain an incredible amount of power. This could potentially make him nearly invincible. He could have enhanced physical abilities, such as super strength and speed. His chakra reserves would likely be off the charts, allowing him to perform powerful jutsu without much strain. However, it could also come with risks. The power might be too much to control, leading to a struggle between the host and the Juubi's influence.
Well, it could be really interesting. Maybe Harry's magic would interact strangely with the chakra system in Naruto. He might be seen as a strange outsider with his unique brand of magic, and could either be feared or revered. He could potentially teach some of the Naruto characters about different types of magic, or perhaps learn some ninja techniques himself.
In some Naruto fanfictions, after Hashirama was sealed, it could lead to a power imbalance in the ninja world. His sealing might be a plot device used by the antagonist to gain an upper hand. For example, if a powerful enemy sealed Hashirama away, it would remove one of the most powerful forces that could oppose them, allowing them to carry out their evil plans more freely.
If Kaguya is sealed in Naruto in a fanfic, Naruto could potentially use Kaguya's power for good. He might be able to access new jutsu or abilities that were previously unknown. However, there would also be risks. The power could be corrupting, like it was for Madara when he got some of Kaguya's power. Naruto would have to rely on his strong will and the support of his friends to keep from being consumed by it. He could also try to study Kaguya's power to find a way to break the cycle of hatred that has been plaguing the ninja world for so long.
