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.
Deidara might be another character to watch out for. His explosive personality could lead to some comical or tense situations when dealing with a baby. And Sasori, with his puppet - like nature, could have an unusual reaction to the presence of a living, breathing baby in their midst.
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.
Pein could be another one. As the leader of the Akatsuki, he might see baby Naruto as a means to an end. He could either want to use Naruto for his own grand plans or, in a more interesting twist, be swayed by Naruto's innocence and change his perspective on the Akatsuki's goals.
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.
In Naruto fanfiction, characters like Jiraiya could also be a 'baby daddy'. He was known for his womanizing ways in the series, so it's not hard to fathom a situation where he has a child. Then there's Itachi. Although his life was full of tragedy and secrecy, a fanfiction could explore a scenario where he has a child before his untimely death. And Kiba could be a character as well. His close bond with his dog Akamaru and his brash personality could lead to a situation where he becomes a 'baby daddy' in a creative fanfiction.
In the 'akatsuki watch battle of gods fanfiction', the Akatsuki members are bound to be the main focus. This includes Sasori, Deidara, and Hidan. However, when it comes to the 'Battle of Gods' part, characters like Whis, who is Beerus' attendant, could also play a significant role as the Akatsuki observe the interactions and battles among these Dragon Ball characters.
Obviously, Naruto himself is the main character in this situation. His friends like Sasuke and Sakura are very likely to be involved. They would be the ones taking care of him, trying to figure out how to turn him back to normal. Kakashi Sensei would also probably be there, guiding them and trying to keep Naruto safe.
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.
I think Konan would be the most likely. She has a more gentle and nurturing side compared to most of the other Akatsuki members. She could use her paper abilities to create things for the baby like a soft bed or toys.
Another pair could be Naruto and Kisame. Kisame is a very loyal member of the Akatsuki. If Naruto were to interact with him, he might be able to break through Kisame's loyalty to the Akatsuki's more extreme ideals and show him a different path. Their connection could be based on Naruto's unwavering belief in friendship and Kisame's longing for something more meaningful in his life.
