One common theme is the struggle between duty and emotion. The Anbu are trained to be cold and efficient, but often the fanfictions explore their inner emotions that conflict with their duties. Another theme is secrecy. Since they are a secret organization, many fanfictions play around with the idea of hidden identities and secrets within the Anbu.
There could be a plot where Naruto's coldness is a result of a traumatic event in the Anbu. Maybe he witnessed something so horrible that he shut down his emotions to cope. And the story could revolve around him either slowly opening up again or becoming even more detached as he delves deeper into Anbu work. Plotlines might also involve him taking on extremely dangerous missions that only someone with his newfound coldness can handle, and how that affects his standing within the Hidden Leaf Village.
Another theme is the exploration of the ANBU world itself. These fanfictions often describe the dark and dangerous nature of the ANBU, the strict training, and the complex hierarchy. Sasuke's experience in this world is then contrasted with his relationship with Naruto, who represents a more positive and hopeful side of the Naruto universe.
One common theme is teamwork. Since they are in the ANBU together, they need to work as a team. For example, in many fanfictions, Naruto's combat skills and Ino's mental abilities combine to overcome enemies.
Another theme is secrecy. Since vampires are not a normal part of the Naruto world, the Anbu vampire has to keep their true identity a secret. This leads to a lot of suspense and plot developments as they try to avoid being discovered. For example, in many fanfictions, they have to be careful not to show their fangs or use their vampire powers in front of others. Also, the theme of outcast is quite common. The Anbu vampire may feel like an outcast in the ninja world due to their unique nature, and this can create a lot of internal conflict and character growth.
One common theme is the struggle for acceptance. Since the Anbu is a tough and often male - dominated group in Naruto, female characters in these fanfictions usually have to fight to be recognized. Another theme is self - discovery. As they face different missions and challenges, they learn more about themselves.
One common theme is leadership. Since Naruto is an ANBU commander, stories often explore how he leads his team, makes tough decisions, and earns the respect of his subordinates. Another theme is secrecy and mystery. The ANBU are a secretive organization, so fanfictions usually have elements of hidden agendas and unknown threats. Also, the theme of redemption can be present, as Naruto may try to redeem the ANBU's reputation or certain characters within the organization.
One common theme is loyalty. In the ANBU, loyalty to the village is of utmost importance. Fanfictions often explore how Naruto and Kakashi uphold or struggle with this loyalty. For example, they might face a situation where their loyalty to each other conflicts with their loyalty to the village.
Power and its control is also a big theme. The Kiri Anbu are powerful warriors, and when combined with Naruto's own power, fanfictions often explore how they use or misuse their powers. There are stories where they have to learn to control their combined strength to face a greater threat.
In Naruto Sharingan Anbu fanfiction, a frequent theme is the search for identity. Anbu operatives with the Sharingan may question who they are outside of their missions and powers. Additionally, themes of redemption can be found. For example, an Anbu who has made mistakes in the past tries to make up for it using the power of the Sharingan. And of course, there's the theme of secrecy and how it affects the Anbu's use of the Sharingan.
One common theme is secrecy. The Anbu are all about secrecy, and many fanfics play around with how Naruto has to keep his identity or certain missions a secret. For example, he might be on a mission where revealing his face or name could be disastrous.
