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.
First, you need to establish their reasons for joining. Sasuke might be seeking power or revenge still and see the Akatsuki as a means to an end. Sakura could be following Sasuke to protect him or because she believes she can change the Akatsuki from within. Then, describe how they interact with the existing Akatsuki members. For example, how Sasuke deals with Itachi's former comrades. You can also add in some action scenes where they go on missions together.
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.
One possible plot twist could be that Naruto and Sasuke join Akatsuki with the secret intention of reforming it from within. They might want to change the organization's goals from causing chaos to actually protecting the shinobi world in a different way. For example, they could try to use Akatsuki's resources and manpower to fight against a greater threat that the traditional shinobi villages are ignoring.
A plot twist could be that Akatsuki has a hidden agenda that Naruto, Sasuke and Sakura are unaware of when they join. Maybe Akatsuki is being controlled by an even more powerful and sinister force, and the three are lured in as pawns. They then have to figure out the real situation and fight not only against the Akatsuki members who oppose their reform ideas but also against this hidden power.
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.
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.
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.
