The plot might center around the OC's growth within the Akatsuki. At first, they'd be in a state of confusion, not fully understanding the Akatsuki's goals. As they get adopted, they'd start to learn the ropes. It could be that they are initially tasked with menial jobs, like gathering information in villages. But then, as they show potential, they are given more important tasks. For instance, they could be involved in a heist with Sasori to steal some valuable ninja tools from a hidden village. Their journey would be about finding their place among these outcasts.
Their abilities could become more lethal. Since the Akatsuki often deals with dangerous missions, the OC might be trained in more deadly jutsu. For example, if they had a basic fire - style jutsu before, they could learn to combine it with other elements under the Akatsuki's tutelage. They could also gain better stealth abilities, as the Akatsuki is known for its secrecy. Maybe they learn how to mask their chakra better like Kakuzu.
Well, he might learn some really dark and powerful jutsu. The Akatsuki members could see his potential as a Jinchuriki and try to mold him into a weapon for their own purposes. Maybe they would also teach him different ways of thinking about the ninja world compared to what he learned in Konoha.
In an 'akatsuki oc fanfic', it's all about expanding the Akatsuki's lore through original characters. These OCs can have diverse personalities, motives, and goals. Some fanfics might center around an OC who is trying to infiltrate the Akatsuki for a noble cause, like stopping their more malicious plans. Others could be about an OC who falls in love with one of the Akatsuki members and how that relationship unfolds in the midst of the Akatsuki's activities. It's a great way for fans to put their own spin on the Akatsuki concept.
A major theme in this type of fanfiction is the exploration of the Akatsuki's ideology. OCs might question or fully embrace the Akatsuki's ideas about peace through war and chaos. Another common aspect is the use of unique abilities. The OCs usually have some special abilities that set them apart and these abilities are often used to interact with the Akatsuki's goals. Additionally, the theme of survival in the dangerous world of the Akatsuki is quite prevalent. OCs have to find ways to survive among powerful and often unpredictable Akatsuki members.
A strong female ninja from a hidden village that was destroyed. She has a big heart and sees Naruto as a chance to start anew. She can teach Naruto her unique fighting style which is a blend of agility and powerful strikes.
The Akatsuki members themselves would have mixed reactions. Some, like Itachi (if he were still alive in the fanfic), might see Naruto as a potential asset but also a threat to their long - term goals. Kisame might be amused by Naruto's presence and see him as a new source of entertainment. Meanwhile, the Leaf Village elders would be outraged. They would see Naruto as a traitor and start devising plans to either bring him back or eliminate him.
For an 'akatsuki no yona x oc' fanfic, let the OC be a skilled archer named Lyra. Lyra had heard tales of Yona and her quest. One fateful day, their paths crossed during a battle against a group of bandits. Lyra's arrows flew true, helping Yona's group fend off the attackers. Yona was impressed by Lyra's marksmanship and invited her to join their journey. Along the way, Lyra and Yona faced many challenges together, and Lyra's unwavering loyalty to Yona grew deeper with each passing day.
If Naruto were adopted by Akatsuki in fanfiction, his power development would be a wild ride. The Akatsuki has access to a lot of knowledge that Konoha doesn't. They could teach him advanced sealing techniques, which could help him better control the Nine - Tails. Also, he might be exposed to different types of chakra manipulation methods that would enhance his combat abilities. However, this new power could also corrupt him or put him at odds with his former self, as the Akatsuki's motives are not always pure.
One popular trope is the redeemed Akatsuki OC. This is where the character starts off as a typical Akatsuki member, but through interactions with the main Naruto characters, they see a different way and change their ways. Another trope is the hidden - identity OC. They pretend to be one thing within the Akatsuki, but in reality, they are working against the group for a greater good. The love - interest trope is also common, where the OC has a romantic relationship with one of the Naruto characters, like Sasuke or Naruto, while being part of the Akatsuki.
