It's very likely. Fanfiction gives authors the freedom to re - imagine the Naruto universe. Kurenai has her own unique characteristics, and making her Naruto's mother would change a great deal of the story. For example, Naruto's upbringing and the relationships he has with other characters would be completely different. This concept could lead to some really interesting and unique fan - made stories.
Well, in some fanfictions, fem Naruto's mother could be a powerful figure, and her interaction with Kurenai could be quite complex. Kurenai, being a skilled kunoichi, might respect fem Naruto's mother for her own abilities. They could exchange knowledge about jutsus or strategies. It could also be that they have a mentor - mentee kind of relationship, with one teaching the other some unique ninja techniques.
Well, perhaps in this fanfiction, Kurenai somehow gets involved in Naruto's life in a very maternal way due to some unforeseen circumstances. For example, she might be the only one who can understand a new power that Naruto has awakened. So, she decides to guide him like a mother would. She would teach him how to control this power, and also give him emotional support which he lacks so much. In the process, their bond grows stronger, and they face many challenges together, like fighting against new and powerful enemies who are after Naruto's power.
Yes, there might be such fanfics out there. In the Naruto fanfiction world, writers often like to create alternative storylines. Having Kurenai as Naruto's mother could lead to a whole different set of character dynamics and plot developments. For example, Kurenai's skills and personality traits would influence Naruto in different ways compared to his canon mother. It could also change the relationships Naruto has with other characters like Sasuke or Sakura.
The plot could involve Kurenai protecting Naruto more fiercely from the start. Since she is a jonin, she might be able to shield Naruto from some of the early discrimination he faced in the village. Also, Naruto could be more involved in the affairs of the genjutsu - related missions and training, and his relationship with characters like Kakashi and Iruka could be different as Kurenai would play a different role in his life compared to Kushina in the original story.
The main characters are surely Kurenai and Naruto. But there could also be other characters like Naruto's friends, such as Sasuke and Sakura. They might be involved as they interact with Naruto in his new relationship with Kurenai. Also, some of the older ninja like Kakashi could be part of the story, perhaps initially being skeptical about Kurenai's new role in Naruto's life but later coming to accept it.
It would be quite different from the original Naruto story. Kurenai is a skilled kunoichi, so Naruto might grow up with more knowledge about genjutsu. His personality could also be influenced by Kurenai's calm and collected nature. For instance, he might be more patient in battle and in dealing with his friends' problems.
One possible plot could be that fem Naruto's mother discovers Kurenai has a special ability that could help save the village. So, she convinces Kurenai to use it, despite Kurenai's initial reluctance.
Tenten could be one of the characters. She could be Naruto's friend and also have a bit of a crush on him. Ino might also be present, using her mind - related jutsu to try and understand the complex relationships in the harem. Rock Lee could show up too, providing some comical relief and also being Naruto's loyal friend in the midst of all the relationship chaos.
I'm not entirely sure if there is a specific 'Naruto cheated on by Kurenai' fanfiction. Fanfiction websites are full of a huge variety of stories, and it could be quite difficult to find one with such a specific plot. You could try searching on popular fanfiction platforms like FanFiction.net or Archive of Our Own using relevant keywords, but keep in mind that the Naruto fandom has a wide range of story themes, and this might be a rather unusual one.
