Who could be the mother in 'Harry has a secret child fanfiction'?

It could be a random villager that Naruto met during one of his travels. Maybe she was from a small village that Naruto helped protect, and they had a brief encounter that led to the child.

It could be an old acquaintance that Percy had a brief relationship with. Maybe someone he met during one of his adventures and then lost touch with, but she later discovers she's pregnant and decides to keep the child a secret from Percy for various reasons.

Maybe it could be a new character. A mysterious woman who Percy meets during one of his adventures. This would add an element of mystery to the story.

It could be an original character created just for this fanfiction. Maybe a girl who Stiles met during a summer vacation and had a brief fling with.

The mother could also be a completely new character created specifically for this fanfiction. She might be from a different realm or have some special powers. And her relationship with Percy could be a complex one, filled with secrets and misunderstandings that led to the situation of having a secret daughter.

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.

Another option could be a new character. A mysterious and powerful ninja from another village who Fem Naruto met during a diplomatic mission. They had a short - lived romance, and he doesn't even know about the child. This would add an element of mystery and the potential for the father to show up later in the story.

In some fanfictions, it could be a character from another magical school. Like a girl from Beauxbatons or Durmstrang. She might have met Harry during an international magical event and they've been secretly seeing each other ever since.

Another possibility is Harry Potter himself. This would be a very different take on their relationship. In some fanfiction, the strong bond between Hermione and Harry could be taken to a new level. Maybe in a situation where they are the last hope for the wizarding world, they conceive a child in secret to carry on some special magic or power that could save the wizarding community.

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.
