Kisame might also be a recruiter. He is a powerful and straightforward member. He respects strength, and Naruto has shown incredible strength. Kisame could be impressed by Naruto's tenacity and his ability to keep getting back up. He might tell Naruto that in the Akatsuki, he can be among others who truly understand his power and won't hold him back like the Leaf Village sometimes does.
Pain could be another possibility. As the leader of the Akatsuki, he has his own vision for the ninja world. If he sees Naruto as a powerful asset that can help him achieve his goals of bringing peace through pain, he would try to recruit him. Pain could show Naruto the suffering in the world that the current ninja system has caused and convince him that the Akatsuki's methods are the only way to change things for the better.
Itachi could be a likely candidate. He has always had a complex relationship with Naruto. He knows Naruto's potential and his importance in Sasuke's life. Itachi might see Naruto as a key to changing the Akatsuki from within. He could approach Naruto with his calm and mysterious demeanor, explaining to him the real goals of the Akatsuki that are hidden beneath their violent exterior.
The Akatsuki members themselves would have mixed reactions. Some, like Itachi (if he were still alive in the fanfic), might see Naruto as a potential asset but also a threat to their long - term goals. Kisame might be amused by Naruto's presence and see him as a new source of entertainment. Meanwhile, the Leaf Village elders would be outraged. They would see Naruto as a traitor and start devising plans to either bring him back or eliminate him.
Itachi could be the most challenging. He's not only extremely powerful with his Sharingan and genjutsu skills, but he's also very intelligent. He could outwit Naruto in battle and has the ability to use Amaterasu, which is a very dangerous jutsu. Naruto would have to be on top of his game both mentally and physically to defeat him.
Naruto could use his shadow clone jutsu to play pranks. For instance, he could make clones that look like the Akatsuki members themselves and have them do really silly things like dance around in circles or sing out - of - tune. The real Akatsuki members would be really confused at first, thinking one of their comrades has gone crazy.
Itachi. He's one of the more complex and morally gray members of the Akatsuki. If he saw that the female OC was in a situation that could potentially cause chaos or harm to the ninja world in a larger sense, he might initiate the rescue. He's also the type who might see some value in the OC that others don't.
Sakura and Sasuke are very likely allies. Sakura has her medical skills and combat abilities, and Sasuke, despite his past issues, has great power. They've been comrades with Naruto for a long time.
Naruto's ideals of friendship and peace would likely clash with the Akatsuki's goals. His presence could make some members question their motives. For example, he might try to convince them that there are better ways to achieve power than through collecting tailed beasts. His positive attitude could be infectious and start to change the overall atmosphere of the Akatsuki.
Itachi and Kisame could be a pair with a close bond. Itachi is a very reserved person, but Kisame seems to respect and understand him to some extent. They often work together on missions, and this could be seen as a form of 'family' bond within the Akatsuki. Another possibility is Deidara and Sasori. Despite their differences in art forms, they seem to have a connection. Deidara looks up to Sasori in some ways, like a younger brother might look up to an older one.
Definitely Itachi. He has a complex character and his own sense of justice. He might see Naruto as a key to changing the shinobi world in a different way than what the Akatsuki originally planned. Another one could be Kisame. He is loyal to Itachi and would likely follow Itachi's lead in taking care of Naruto.
Yes, there are several fanfictions with this concept. In these fanfictions, Naruto's character often undergoes significant changes as he joins the Akatsuki. His motives for joining can vary from seeking a different path to having been influenced by certain events or characters. It's an interesting twist on the original Naruto storyline.
Pain would still be a likely candidate. His Rinnegan gives him a powerful and commanding presence. He has the ability to see the big picture and make strategic decisions for the group.
