Perhaps a time - travel fanfiction where Hidan and Itachi are sent to a different era. They have to rely on each other to survive in this new and strange world. Hidan's ability to not die easily and Itachi's powerful jutsu could be combined in creative ways to face the challenges of this new time period.
A fanfiction could explore a scenario where Hidan is injured and Itachi has to take care of him. Itachi, being the more composed one, tries to keep Hidan in check while also learning about Hidan's unique immortality. This could lead to some interesting conversations between them about life, death, and their roles in their respective organizations.
One idea could be a story where Hidan and Itachi are forced to work together on a mission. They start off disliking each other but gradually, through shared experiences and understanding, they develop feelings for one another. It could explore how their different personalities, Hidan's brashness and Itachi's calmness, create an interesting dynamic.
One common theme is the clash of their personalities. Itachi is calm and calculating, while Hidan is wild and impulsive. Fanfictions often explore how these two contrasting personalities interact. Another theme could be the exploration of their different beliefs. Itachi has his own complex moral code, and Hidan has his extreme religious views regarding Jashin.
Perhaps in a fanfiction, Hidan gets injured in a way that only Sakura's advanced medical ninjutsu can heal. As she heals him, she tries to understand his strange beliefs. This could lead to a series of interactions where Hidan starts to see Sakura not just as a healer but as a strong and worthy opponent. And Sakura sees a different side of Hidan beyond his blood - thirsty and violent exterior.
Some fanfictions might explore a scenario where Itachi and Naruto have to go on a secret mission together. During this mission, they encounter various challenges that force them to rely on each other. Itachi's calm and calculated nature combined with Naruto's impulsiveness could lead to both comical and tense situations as they strive to complete the mission.
How about a Hidan crossover with the DC Universe? He could end up in Gotham City and be a new kind of villain that Batman has to deal with. His immortality would make him a very difficult opponent for the Dark Knight, and his disregard for life would put him at odds with Batman's moral code.
Well, I'm not sure which specific ones are the absolute best as it depends on personal taste. However, some fanfictions might center around the idea of Itachi trying to understand Hidan's immortality while Hidan is intrigued by Itachi's powerful jutsu. This could lead to a series of adventures where they gradually form a bond. You might also want to look for ones that have good reviews or high ratings on the fanfiction platforms, as that can be an indication of quality content.
The theme of power dynamics is also quite common. Itachi is extremely powerful, and Hidan has his own unique abilities. Fanfics often explore how they balance or compete in terms of power, whether it's in a fight or in their day - to - day interactions in the story world.
A prevalent theme in Hidan x Itachi fanfiction (not lemon) is the idea of redemption or change. For example, Itachi's journey towards atoning for his sins and how Hidan might be involved in that process, either as an obstacle or a catalyst. Also, the exploration of their different beliefs. Hidan's fanatical religious beliefs and Itachi's more complex moral code can create a lot of tension and development in their relationship within the fanfiction stories.
Well, I don't really recommend seeking out 'lemon' fanfiction which usually implies adult - themed content. But if you're interested in regular Hidan x Itachi fanfiction, you could look for it on platforms where Naruto fanfics are shared. You might have to sift through a lot of stories to find ones that are well - written and stay true to the characters' personalities.
A plot could involve Itachi coming back to life and trying to make amends with Sasuke while also having to deal with Naruto's newfound power. Itachi sees the bond between Naruto and Sasuke and tries to help them strengthen it further for the sake of the Hidden Leaf Village. He could train them in some of his unique jutsu.
