Well, perhaps Naruto joins the ANBU Black Ops to gain more power and knowledge to protect the village in a different way. The story could show him learning new and more dangerous jutsu that are exclusive to the ANBU. His relationships with his old friends might change too. They could be worried about him, or he might start to distance himself from them as he gets deeper into the ANBU world.
In this kind of fanfiction, one possible plot development could be Naruto having to deal with the secrecy aspect of ANBU. He might struggle with the morally grey missions they undertake. For example, he could be sent to spy on an old acquaintance. Naruto, being Naruto, might try to find a more positive solution to the situation rather than blindly following orders.
Well, in a fanfiction where Naruto joins ANBU, his training would intensify. He'd be trained by some of the toughest ANBU veterans. His skills in combat would become more refined as he'd learn to use weapons like kunai and shuriken with more precision. He may also develop new jutsu that are more suitable for covert operations. His growth as a ninja would be different from the regular path, focusing more on secrecy and assassination if required.
His character could change in several ways. Firstly, he'd likely become more stealthy. In the ANBU, being able to move without being detected is crucial. Also, he might become more cynical. The ANBU deals with some dark stuff, and that could make Naruto question the world around him more. He may still hold onto his core values of protecting his friends and the village, but he'd view things from a more jaded perspective. He'd also have to be more calculating in his actions, thinking several steps ahead like the other ANBU members.
Well, in such a fanfiction, perhaps Naruto has just lost Sasuke again and is deeply depressed. The ANBU, seeing his skills and his need for a distraction, recruit him. He starts off being a bit of a misfit in ANBU, not following all the rules because of his independent nature. But as he continues, he starts to understand the importance of their work. He might even form new bonds with his ANBU comrades, which slowly help him come out of his depression.
In such a fanfiction, the plot could involve Naruto being constantly overlooked by the village. Fed up with this, he decides to join ANBU to prove his worth. He might face challenges like distrust from his ANBU comrades at first because of his reputation. But as he goes on missions, he shows his skills and determination, gradually earning their respect and changing their perception of him.
Well, one possible plot development could be Naruto joining the ANBU to seek revenge for Asuma's death. He might use the ANBU's resources and training to become stronger and hunt down those responsible.
Maybe an Anbu agent who has a special ability that no one in the village knows about. He or she is sent on a mission related to Orochimaru. During the mission, the agent starts to question the morality of the Anbu's actions as they often involve killing without trial. This could lead to a character - driven story about loyalty, morality, and self - discovery.
It could be Kakashi. He has a lot of experience and a mysterious past that would fit well with the Anbu Black Ops setting. His Sharingan would give him an edge in their dangerous missions.
One possible plot could be Naruto facing the internal politics of ANBU. He might struggle to adapt to their more secretive and sometimes morally gray operations compared to his usual straightforward ninja way. For example, he could be assigned to a mission where he has to spy on a former ally, creating an internal conflict within him.
One plot twist could be that the person who cheated on Naruto actually has a very good reason, like they were forced to do it to protect Naruto from a greater threat. Another could be that in ANBU, Naruto discovers that the cheating incident was part of a larger conspiracy against him. Maybe his new ANBU teammates turn out to be related to the cheater in some way, creating a lot of internal conflict for Naruto.
One possible plot development could be Naruto facing initial hostility in Iwa. Since he's from Konoha, the Iwa ninjas might be suspicious of him at first. But Naruto, with his determination and unique skills like the Rasengan, could gradually earn their respect. He might also learn new jutsu unique to Iwa and form new alliances, perhaps even finding a way to bridge the gap between Konoha and Iwa in the long run.
