One idea could be a story where Itachi and Kushina meet in a parallel universe. In this universe, the events of the original Naruto storyline are altered, and they end up on the same side, fighting against a new common enemy. Their unique abilities, Itachi's Sharingan and Kushina's powerful chakra, would make for an interesting combination in battles.
Let's imagine Itachi Uchiha in love with a fellow Uchiha. They grew up together, trained together. Their love was based on a deep understanding of each other's pain and power. But when the Uchiha clan's fate was at stake, Itachi had to make difficult choices. His love for her was strong, but his loyalty to the village made him do things that seemed to shatter their relationship. In the end, his love remained in his heart, a hidden and painful memory.
Naruto would likely be involved. He has a strong bond with Kakashi and would surely try to rescue him. Sasuke could also be part of the story. Given his relationship with Itachi, it would add an interesting dynamic.
Itachi Uchiha was a complex and tragic character. He was a prodigy in the Uchiha clan. He killed his entire clan except for his younger brother Sasuke, which was a shocking act. But in fact, he did this under orders from the Hidden Leaf Village elders to prevent a coup by the Uchiha clan that would have led to civil war. He lived as a double agent, making himself seem like a villain in Sasuke's eyes so that Sasuke would grow strong enough to kill him and be hailed as a hero, thus protecting the village and Sasuke at the same time.
Sure. There are often crossovers in fanfiction. Writers like to combine different beloved fictional characters. For the 'Harry Potter is Itachi Uchiha' idea, it could be really interesting. For example, Itachi's Sharingan abilities could be compared or integrated with magic in the Harry Potter universe. It might be a bit of a stretch in terms of the two very different settings, but that's the beauty of fanfiction. You can find such fanfictions on websites like Archive of Our Own or FanFiction.net if they exist.
Itachi Uchiha's full story is one of great sacrifice and hidden motives. As a member of the Uchiha clan, he was aware of the growing unrest within the clan against the Hidden Leaf. Instead of allowing a full - blown civil war, he made the difficult choice to kill his clan mates. His actions were misjudged by many, especially Sasuke. Itachi's time in the Akatsuki was also full of intrigue. He constantly had to balance his true loyalty to the Leaf with his role in the criminal organization. And all along, his love for Sasuke was his driving force, even if it seemed like he was cruel to him at times. He wanted Sasuke to become strong enough to take revenge on him and in doing so, free himself from the cycle of hatred.
Another good one is 'Itachi Meets the Avengers'. Here, Itachi's calm and strategic mind makes for some amazing interactions with the Avengers. His abilities seem out of this world to the heroes at first, but they soon realize how useful he can be in battles against powerful foes like Thanos.
Often, the theme of friendship between Kakashi and an Uchiha character is seen. Despite the differences between Kakashi and the Uchiha, they form strong bonds in fanfics. Also, the exploration of the Sharingan, the Uchiha's special ability, in relation to Kakashi is a common theme. Maybe Kakashi is learning more about it or helping an Uchiha with its control.
There could be. There are a lot of creative fans out there who come up with all kinds of unique story concepts. However, I'm not sure exactly where you would find it. You could also check Naruto - related forums where fans might discuss and share such fanfics. It might take some time and effort to search for it though.
The 'itachi uchiha lemon forced fanfiction' could be a very unique take on the character of Itachi Uchiha. If we consider the non - inappropriate side of things, perhaps it's about Itachi being forced into a new role or mission that he didn't anticipate. It might explore his character in a different light, showing how he copes with being pushed into something he may not have wanted. It could also be about how his relationships with other characters change as a result of this forced situation, and how he uses his skills and intelligence to navigate through it.
