They might be really amused. Some of the fanfiction could be so out - of - the - box that it would make them laugh. For example, if there was a fanfiction about them all becoming bakers instead of ninjas, it would be a hilarious concept for them.
It could potentially inspire them. Maybe they'd see a new strategy or a different way of interacting with each other in the fanfiction. For instance, if a fanfiction had a really creative plot where they worked together in a unique way, they might consider adapting some of those ideas into their real - life ninja activities.
One possible scenario is that Sakura could bring her medical skills to the Akatsuki. She might be able to heal some of the members who are constantly in battle and injured. This could change the group's dynamic as they would no longer have to worry as much about their wounds. Also, her combat skills could be enhanced by learning from the Akatsuki's unique fighting styles.
Well, in such a fanfiction, Sakura might be used as a bargaining chip. The Akatsuki could try to exchange her for something valuable, like secret jutsu. Or they might want to extract information from her about Konoha's defenses.
In the 'Akatsuki babysits Naruto' fanfiction, Pain might see Naruto as a potential tool or threat. He could try to indoctrinate Naruto into the Akatsuki's way of thinking. Meanwhile, Konan might be the more motherly figure, making sure Naruto is fed and clothed properly. Deidara might also be there, constantly arguing with Naruto about what is 'art' and getting into comical debates.
Well, if Naruto joined Akatsuki, he would likely face a huge internal struggle. He has always been against the Akatsuki's actions in the original series. His values of friendship and protecting the village would be put to the test. He might try to change the Akatsuki from within, using his talk - no - jutsu to convince some members to abandon their more evil plans. But he would also be in a difficult position as the Akatsuki is filled with powerful and dangerous individuals.
Well, Naruto might be interrogated for information about the Hidden Leaf. The Akatsuki are always after secrets, especially about the Jinchuriki. So they could be trying to find out more about the Nine - Tails within Naruto.
In this fanfiction, the Akatsuki might first be really confused about finding a baby. Some members could be immediately protective, like Itachi. He might see the baby as an innocent life to safeguard. Others, like Hidan, might be annoyed at first but gradually grow fond. They could end up raising the baby within their hideout, teaching it their unique skills in a strange way, like how to move stealthily.
If Sakura gets kidnapped by the Akatsuki in fanfiction, Sasuke could also get involved. Since he has his own history with the Akatsuki, he might use his knowledge to track them down. Also, Sakura herself could be trying to find a way to escape from within. She's a strong kunoichi, after all. She might be gathering information about the Akatsuki's plans while being held captive.
Well, in this kind of fanfiction, Minato might be able to use his powerful jutsu to take on the Akatsuki members one by one. He could teach Naruto some secret techniques that he never had the chance to before. And maybe he would reform the Leaf Village's defenses to better protect against future Akatsuki threats.
Female Naruto joining the Akatsuki in fanfiction would be really interesting. Firstly, her relationship with other members would be complex. She might have a strange bond with Itachi, as they both have a sense of protecting something important. Secondly, she could use her talk - no - jutsu in a new way among the Akatsuki members. Her energy and positive attitude could either be a nuisance or a source of inspiration for them. And her combat skills would definitely make her a force to be reckoned with in the Akatsuki.
Well, if Naruto and Tenten joined Akatsuki, it would be a huge shift in the Naruto universe. Naruto's ideals are so different from Akatsuki's. He believes in protecting the village and his friends, while Akatsuki is mostly about causing chaos and collecting the tailed beasts. Tenten, on the other hand, is a strong - willed kunoichi. Maybe they could try to change Akatsuki from the inside. But they would face a lot of opposition from the existing Akatsuki members who have their own agendas. It could lead to some really interesting power struggles and character development.
