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.
Fan Xian's strength was above the eighth rank, but it was not explicitly mentioned whether he was eighth or ninth rank. Fan Xian's strength in Northern Qi should have reached the eighth level, but he was no match for the ninth-level aces Yan Xiaoyi and Friar He. When Fan Xian had first entered the eighth rank, he had almost been killed. Later, after experiencing many assassinations, his strength had improved. Combining this information, one could deduce that Fan Xian's strength was between the eighth and ninth ranks.
Fan Xian's strength was between the eighth and ninth ranks. Although it was still uncertain whether he was an eighth or ninth-level, Fan Xian displayed extraordinary strength in the play. It was as if he had barged into the Royal Palace at night and successfully dodged Yan Xiaoyi's arrow. However, Fan Xian's power might have an even more shocking side to the plot, so his martial arts level still needed to be observed. In summary, Fan Xian's strength should be between the eighth and ninth ranks.

He had won easily in his battle with Cheng Jushu, but he had not surpassed the eighth rank. However, Fan Xian's strength had improved after experiencing many assassinations. He had also said that his zhenqi had gone up another level. Although Fan Xian had reached the peak of the ninth-level in the end, he was still far from the realm of a Great Grandmaster.
