Kakuzu might be an unexpected choice. His focus on money and practicality could lead the Akatsuki in a more resource - focused direction in the new world. He would ensure they have the necessary funds and materials to survive and thrive in this different setting.
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.
Itachi could also be a strong contender. His intelligence and self - sacrifice nature could make him a respected leader. He is well - versed in the ways of the Akatsuki and could lead them in a more diplomatic way in the new world.
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.
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.
Itachi. He has his own moral code and he might see something in Chibi Sakura that reminds him of his own will to protect. He could form an alliance with her if he believes it would be for the greater good, like stopping the more extreme members of Akatsuki from causing too much destruction.
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.
If Naruto became the leader of Akatsuki in fanfiction, his leadership would change their goals significantly. Naruto has always been against the Akatsuki's violent and often cruel methods. He might start by changing the Akatsuki's internal structure. Instead of being a group that operates in the shadows and uses fear, he could make it an open organization. Their new goal could be to bridge the gaps between different ninja villages. For example, he could use the Akatsuki's members' diverse skills to facilitate trade and cultural exchange between villages. This would be a huge departure from the Akatsuki's traditional goals of domination and destruction.
Obviously, Obito is one of the main characters. He has a complex backstory and his presence is bound to have a big impact on the Akatsuki.
Obviously, Sakura would be one of the main characters. And the members of the Akatsuki would also be important. For example, characters like Itachi or Pain might play significant roles as they are key figures in the Akatsuki. They could be mentors or antagonists to Sakura depending on how the story is written.
Pain could also be a major character. His ideology and the Akatsuki's goals under his leadership might be affected by the presence of baby Naruto. He might see Naruto as a potential threat to his plans or as an opportunity to change the Akatsuki's path. Also, Konan might be involved as she often has a more empathetic side compared to some of the other Akatsuki members and could play a role in taking care of the baby.
Definitely Naruto. Then, Deidara could be an interesting character in this. His explosive personality and unique art of combat could influence Naruto in some ways. He might teach Naruto some of his skills while also getting frustrated with Naruto's different approach to things. Sasori could also be a part of it. His puppet - making skills and his cold, calculated nature could add an element of mystery to how Naruto is raised within the Akatsuki.
Well, Naruto might change Akatsuki's goals by introducing his own values. Naruto believes in protecting the village and friends. So he could steer Akatsuki away from their original plans of chaos and destruction. For example, he might focus the group on protecting the shinobi world from greater threats rather than causing internal strife.
