In many fanfictions, Sakura could be a potential mother. Since she has a close relationship with Naruto in the original series, some fans might imagine a scenario where they end up together and have a son. Another possibility could be Hinata. Given her deep love for Naruto, it's not hard to fathom a fanfiction where they have a secret son.
His son could inherit Naruto's powerful chakra and the ability to use the Rasengan. Maybe also have some form of enhanced speed and strength like Naruto. After all, Naruto's powers are quite dominant.
It could be Hinata. Even though in the original story they are openly married, in a fanfic scenario, there could be a situation where their relationship was kept secret for some time and she gave birth to a son secretly. Maybe due to some threat to the village or Naruto's safety.
The idea of Naruto being the secret son of Kushina and Mito in fanfic is a fascinating deviation from the original Naruto narrative. Fanfic authors sometimes like to break the norms and create alternative storylines. This particular concept could potentially change a lot of the story's dynamics. For example, it could lead to different power inheritances or different relationships with other characters. But it's crucial to remember that this is a fan - made concept and not based on the official Naruto storyline which clearly states Naruto's parents as Kushina and Minato.
Well, one plot twist could be that the son has some unique power that neither Naruto nor his friends are aware of at first. Maybe it's a power that was dormant until a certain event triggered it.
It could be Hinata. In the original series, Hinata has a deep affection for Naruto. In a fanfiction, it would be a natural progression for her to be his secret fiance. Maybe they got engaged secretly to avoid some political unrest in the village.
It might also be Gaara. Their initial encounters were filled with tension, but as the story could be twisted in fanfiction, that could develop into a different kind of relationship. Gaara's own journey of self - discovery and Naruto's influence on him could be a basis for a romantic relationship in fanfic.
Well, it could be a fanfiction where Naruto discovers he has the Mokuton ability in a very unexpected way. Maybe he gets it through some ancient power transfer or a connection to a long - lost clan. And this new power of Mokuton could lead him to face new enemies or form new alliances. It might also explore how his friends react to this new side of him.
It could be that Naruto is secretly training a new and powerful jutsu that he doesn't want anyone to know about yet. Maybe he's afraid that if his enemies find out, they'll try to stop him before he perfects it.
The son could be developed as a very determined character. Since he grows up with a banished father, he might have a strong desire to change the situation. He could be skilled in both physical and mental aspects, like being an excellent fighter and also having great strategic thinking, just like Naruto.
