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.
Sasuke could be a great choice too. After leaving the village, he could have some interactions with the Anbu Black Ops, either as an enemy or as an unexpected ally. His quest for power and revenge could be intertwined with the secretive missions of the Anbu.
Iruka could also be an interesting main character. Imagine him being recruited into the Anbu Black Ops for some special reason. He would have to adapt from being a simple teacher to a stealthy and deadly operative, and his kind heart might clash with the harsh reality of the Anbu world.
Kakashi is often a popular character in Naruto Anbu Black Ops fanfiction. His cool and mysterious nature during his Anbu days makes him an interesting subject. Writers like to explore his past missions and his relationships with other Anbu members.
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.
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.
The main characters could be some of the lesser - known but powerful shinobi from the Hidden Leaf. For example, Might Guy. His unwavering determination and powerful taijutsu could be a great asset. Then there's Ino. She could use her mind - transfer jutsu to gather information from the zombies or the source of the zombie outbreak. And Neji, with his Byakugan, could see the weak points of the zombies and direct the attacks of the Black Ops more effectively.
Sakura is the key character in sakura anbu black ops fanfic. However, there may be some original characters created specifically for the fanfic. These could be fellow Anbu members who become important to Sakura's story. For example, a senior Anbu member who takes Sakura under their wing and trains her in the ways of the Anbu. There could also be antagonists, perhaps rogue ninjas or members of other hidden villages who are the targets of the Anbu Black Ops that Sakura is part of.
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.
Itachi Uchiha is another great character to feature. His complex motives and his role in the Uchiha massacre while being in the ANBU make for a lot of interesting story possibilities. You could write about his internal struggles and how his time in the ANBU influenced his decisions.
It could be Kakashi. He has a complex past and has been part of the ANBU. Given his experiences, he might have a reason to leave Konoha. Maybe he discovers something about the Sharingan or the Uchiha massacre that makes him question the village's integrity. He's a popular and well - developed character, so a story about him leaving as an ANBU would be interesting.
Kakashi could be a great main character as an ANBU commander. He has the skills, experience, and the mysterious allure that suits the role. He's known for his combat prowess and his ability to think on his feet, which are essential for an ANBU commander.
One interesting Naruto Anbu Black Ops fanfiction could be one where a new character is introduced into the Anbu and has to deal with the secrecy and danger. For example, a story where this new Anbu member discovers a hidden plot within the organization itself.
