Well, in fanfiction, the significance of Kurenai and Itachi is often enhanced. In the original Naruto, their roles are somewhat defined within the broader narrative. However, fanfiction allows for a different take. It can focus on their unexploited potential as characters. For example, their shared knowledge of genjutsu could be a starting point for a completely new story arc in fanfiction. Also, their personalities can be tweaked or explored more fully, like exploring Itachi's more human side in relation to Kurenai, which gives a fresh perspective compared to the original.
In fanfiction, the relationship between Kurenai and Itachi can be quite complex. It might be portrayed as a friendship that develops in unique ways due to their different personalities and roles in the Naruto universe. Kurenai is a strong and intelligent kunoichi, while Itachi has his own deep and mysterious character. Sometimes, their relationship could be explored in terms of mutual respect for each other's skills.
The duck could symbolize peace or friendship. Maybe Naruto gives it to Itachi as a sign of truce or new - found understanding between them.
Fem Naruto's appearance would change in several ways. Her body shape would be more feminine, with curves. Her eyes might be a bit larger and more expressive. In terms of hair, not only would it be long, but she could also style it in different ways, like braids or ponytails. And her skin tone might be a bit fairer compared to Naruto. She would also have a more slender build overall.
In the fanfiction, it could also be a way to bridge the gap between their two clans. Naruto, as someone who wants to bring peace to the ninja world, giving gifts to Itachi can be seen as an attempt to heal the old wounds between the Uchiha clan and the rest of Konoha.
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.
One aspect to consider in this fanfiction scenario is how their marriage would affect the other characters. The young ninja in the village might look up to them as a couple. Naruto's friends like Sakura and Sasuke would have different reactions. Sakura might be happy for Naruto but also a bit envious, while Sasuke might initially be skeptical but come to respect their relationship over time. And their family life could involve Naruto teaching their future children his unique ninja skills, while Kurenai imparts her wisdom about the more subtle aspects of being a ninja.
I'm not entirely sure if there is a specific 'naruto is kurenai son fanfiction' out there. Fanfiction platforms are filled with all sorts of creative ideas, but it can be difficult to know for sure if there is one specifically for this concept. You could try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. Maybe start with searching for Naruto - Kurenai family relationship or something similar to see if any relevant stories pop up.
In most Naruto fanfictions, there is no such plot where Kurenai cheats on Naruto because they don't have that kind of relationship in the original story. Kurenai has her own story arc mainly related to Asuma. So it's very unlikely to find such a scenario in regular Naruto fanfictions.
In the original Naruto series, orbs might be more straightforward in their use. But in fanfiction, they can be used in crazy ways. For instance, they could be used to time - travel or to create alternate universes. Writers in fanfiction have more freedom to be creative with the orbs.
