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.
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 theme of sacrifice is also prevalent. Given their complex situations, they may be required to sacrifice things for each other or for the greater good. This could be sacrificing their own safety, their reputations, or their relationships with others in the fan - created stories.
Well, one possibility could be that Itachi has some hidden motive related to the Uchiha clan's secrets. He might think Kakashi knows something crucial. So, he kidnaps him to interrogate him in a secret location.
Another theme could be the challenges they face together. Given their roles in the Naruto universe, they might encounter various threats or obstacles that they have to overcome as a team, which can strengthen their bond in the story.
In a straight - up fight, Itachi has some very powerful abilities. His genjutsu can be extremely difficult to break out of, and his ninjutsu attacks are strong. But Batman is no slouch. He has fought against some of the most powerful villains in the DC universe. He would study Itachi's moves and try to find a pattern. Batman might also use his wealth to create some sort of countermeasure to Itachi's Sharingan. Overall, it's a very close call and would likely depend on how the writer of the fanfiction wants the story to go.
Minato might also be a prominent character. As their teacher, he can influence the way Obito and Kakashi interact. In some fan fictions, he could be the one to help them resolve their differences or provide some crucial information about their past that changes their current situation.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often tags related to 'Female Itachi' and 'Kakashi' that can help you narrow down the search. Many authors create unique stories in this pairing, exploring different scenarios and character dynamics.
One great 'kakashi x itachi fanfic' could be 'The Bond Beyond Comrades'. It delves deep into their relationship, exploring how their different outlooks on life and loyalty interact. Another one is 'Silent Understanding', which focuses on their unspoken respect for each other during their missions together.
The theme of redemption also pops up often. Since Itachi has a complex and somewhat dark past, the OC might be a factor in his journey towards redemption. And for Kakashi, the OC could be a new chapter in his life, helping him move on from past traumas or regrets. This makes for a very interesting dynamic in these fanfictions.
