Well, for one thing, the Akatsuki members would have to adjust to having two very powerful and opinionated new members. Naruto is known for his unwavering belief in friendship and Sasuke has his own complex motives. Their joining could lead to internal conflicts within Akatsuki. Some members might see them as threats to their own agendas. However, Naruto and Sasuke together could also bring a new sense of unity to the group, as they are both extremely strong and could inspire loyalty among some of the Akatsuki members who might be tired of the current state of affairs.
In fanfiction, if Sasuke and Sakura joined Akatsuki, it could lead to a complete shift in the power dynamics. Sasuke already has a complex relationship with the Akatsuki members. With Sakura by his side, she might act as a moral compass for him. Maybe they would try to reform the Akatsuki from within, or they could be forced to carry out some dark missions that would test their relationship.
Sasuke might be initially shocked. He has always seen Naruto as a rival and suddenly finding out Naruto is a girl could completely change his perception. He may start to view Naruto in a more protective way, as his traditional views of gender roles might make him feel the need to safeguard her now that he knows she's female.
Well, if Sasuke finds out Naruto is a girl in fanfiction, it could completely change their dynamic. Maybe Sasuke would start to see Naruto in a new light, perhaps more protectively. Their relationship might become more romantic as Sasuke realizes his feelings for Naruto are different from what he thought. It could also lead to some interesting plot twists, like Sasuke having to re - evaluate his rivalry with Naruto.
Well, in fanfiction, if Naruto and Gaara joined Akatsuki, it would be a total chaos for the ninja world. Akatsuki's goals would likely be completely derailed. Naruto is all about friendship and protecting the village, and Gaara has also turned to the side of protecting his people. Their values would clash with Akatsuki's more malevolent intentions. Maybe Naruto would try to reform Akatsuki from the inside, and Gaara would be there to back him up with his powerful sand abilities.
Well, in a fanfiction where Naruto and Hinata join the Akatsuki, there could be a lot of drama. Naruto's powerful jutsu and Hinata's Byakugan would be great assets to the Akatsuki. However, they would face a lot of internal conflict. The Akatsuki members might not trust them easily. Naruto would probably try to convince the members to give up their evil ways. And Hinata would be there to support Naruto and also use her skills to help the group in a more positive way, like gathering intelligence in a non - violent manner.
One possibility is that they join under false pretenses. Maybe they think Akatsuki has a different goal than it actually does. For example, Naruto might believe they are working towards peace in a different way and Temari could be there to keep an eye on Naruto. However, once they discover the true nature of Akatsuki, they would have to decide whether to stay and try to change it from the inside or leave and become enemies.
In this type of fanfic, Sasuke's motivation to protect Naruto could be his realization of their deep - rooted bond. Maybe he has had a change of heart after all their past encounters. Sasuke could use his Sharingan to foresee any danger coming Naruto's way from the Akatsuki members. He'd be like a shadow, always there but not fully noticed by the Akatsuki, making sure Naruto stays safe.
