Well, it could start with Sasuke joining the Akatsuki with the sole intention of protecting Naruto from within. He could form alliances with some of the less - evil members who might also have a grudge against those who want to harm Naruto. For example, he could team up with Zetsu, who has his own motives and might be persuaded to help protect Naruto in exchange for something.
The story could also involve Sasuke learning about a powerful Akatsuki weapon or jutsu that is specifically designed to target Naruto. He then goes on a quest within the Akatsuki to either destroy or steal this weapon/jutsu. Along the way, he has to face many challenges and suspicions from other Akatsuki members. But his determination to protect Naruto drives him forward. He might even have to make some sacrifices, like giving up some of his own power or secrets to keep Naruto safe.
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.
One way it could develop is that the baby has some special powers that attract the attention of villains. Naruto and Sasuke then have to protect the baby while also trying to teach it right from wrong. As the baby grows, it could start to have its own dreams and goals, which might be different from what Naruto and Sasuke expect, adding more drama to the story.
Naruto in fanfic might be shown as even more heroic when facing Akatsuki, like single - handedly taking on multiple members. Sasuke could be more of an anti - hero, having some secret alliance with Akatsuki for a time. Sakura is often made into a more powerful ninja than in the original, so she can better deal with Akatsuki threats. Akatsuki members are sometimes given more backstories and sympathetic traits in fanfic.
In fanfics, the relationship between Naruto, Sasuke, Sakura and Akatsuki can be extremely diverse. Naruto often represents the ideal of never - giving - up. Sasuke is the brooding, complex character. Sakura can be a strong - willed female character. Akatsuki, on the other hand, is usually portrayed as the antagonists. Fanfic writers may create various scenarios. For example, they might write about how Naruto tries to redeem members of Akatsuki, or how Sasuke's path intersects with Akatsuki's goals in ways different from the original story. And Sakura could play a role in either helping or hindering these interactions.
Their relationship would likely be full of tension at first. Naruto would be the one trying to reach out to Sasuke, while Sasuke would be more guarded. But as they face the challenges within Akatsuki together, they would slowly start to trust each other again.
The plot could start with the other characters being oblivious to her yandere nature. As the story progresses, her actions would start to raise suspicions. For example, if there's a training session and she gets overly aggressive towards someone who accidentally hurt her love interest during sparring.
Well, if Naruto were to create an Akatsuki fanfiction, one way the storyline could develop is by having Naruto try to understand the motives of the Akatsuki members more deeply. He might explore the idea of redemption for some of them. For example, he could write about how Pain, after seeing the destruction he caused, might have a change of heart. Naruto could also create scenarios where the Akatsuki members interact with the villagers of Konoha in a more positive light, like how Sasori could use his puppet - making skills to help the kids in the village create toys instead of weapons.
In many such fanfics, Naruto's character often becomes more vulnerable yet also stronger in a different sense. His pregnancy makes him rely on Sasuke more, but at the same time, he is determined to still be a great ninja. Sasuke, on the other hand, becomes more nurturing. He steps up to protect Naruto and the unborn child, showing a side of him that was not as evident before.
In a fanfiction, Naruto and Sasuke in Akatsuki might have a story where they are sent on a special mission together by the Akatsuki leaders. Along the way, they face many challenges that test their bond. Sasuke might initially be more in tune with the Akatsuki's ways, but Naruto tries to convince him to find a better path. As they complete the mission, they start to change the Akatsuki's ideology bit by bit.
Well, one possible plot could be that they join initially to spy on Akatsuki from the inside. Naruto might think he can change the Akatsuki members' minds with his talk - no - jutsu. Sasuke could be there to find out more about the secrets Akatsuki is hiding, especially those related to his family. Maybe they end up causing chaos within Akatsuki as they slowly turn some of the members towards a more positive path.
