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.
It would be amazing. Naruto would bring his energetic and fearless attitude. He'd probably befriend the Hulk and they'd have some wild adventures. Hinata would be more reserved but her skills would be respected. She might train with Black Widow to improve her combat skills further.
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.
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.
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 some fanfictions, Naruto could be a double agent in the Akatsuki. His goal might be to infiltrate and destroy the organization from within. Hinata could be his support, using her Byakugan to gather intelligence. For example, she might be able to detect hidden Akatsuki bases or members who are trying to ambush Naruto.
Power and its consequences are often explored. Hinata's Byakugan power can be a key factor. When she's among the Akatsuki, she might have to use her power in new ways. And the Akatsuki's pursuit of power and how it affects Hinata and the world around her is another aspect. This can lead to moral dilemmas for Hinata as she decides whether to use her power for good or if she gets influenced by the Akatsuki's goals.
Sakura would likely become more ruthless. In her original setting, she is a healer, but in Akatsuki, she might have to be more combat - focused and less hesitant to use force. Ino would probably become more secretive. Her mind - transfer jutsu could be used for more devious purposes within Akatsuki, and she'd need to keep her true intentions hidden. Hinata might gain more confidence in a different way. Instead of being shy around her peers in Konoha, in Akatsuki she would have to assert herself among much more dangerous individuals. Tenten would change her view on weapons. Akatsuki's access to different types of dangerous weapons could make her more obsessed with obtaining and mastering them.
