Perhaps a plotline where an Anbu member is revealed to have a personal connection to a major villain in the Naruto universe. This could create a lot of internal conflict within the village as they try to figure out how to deal with this revelation. For example, if the Anbu member is related to Orochimaru and has been secretly feeding him information, it would be a huge shock.
Another possible plotline is the relationships between the elite ANBU members. They might have a complex web of friendships, rivalries, or even romances that develop over the course of the story. This could add a lot of depth to the characters and the overall fanfic.
A possible plotline is Naruto using his unorthodox methods to solve ANBU - related problems. His creativity and ability to think outside the box could lead to new strategies for the ANBU. He might come up with a new way to gather intelligence or take on a powerful enemy that the traditional ANBU methods couldn't handle.
In some fanfictions, Naruto in the ANBU could be involved in a special mission to uncover a long - hidden conspiracy within the Leaf Village. He would have to use his unique skills, like his shadow clones, in a more stealthy way. And along the way, he might make unexpected allies among the ANBU ranks who see his potential and different way of thinking.
Maybe Itachi. Since he was also part of the Anbu, and his true motives and actions while in the Anbu could be a major focus. His complex relationship with the village and his role in the Uchiha massacre could be tied to the Anbu revelations in the fanfic.
One interesting plotline could be Naruto and Sakura being assigned a top - secret mission in the ANBU. They have to infiltrate an enemy organization together. Along the way, they discover new powers within themselves and also deepen their bond as comrades. Maybe Naruto unlocks a new form of his chakra while Sakura refines her medical ninjutsu to be used in combat situations in a more deadly way.
Maybe Naruto discovers a conspiracy within Konoha while he's in the ANBU. It could involve some of the higher - ups trying to gain more power at the expense of the village's well - being. Naruto then has to decide whether to expose it and risk his position or try to solve it quietly.
One interesting plotline could be Naruto's struggle to adapt to the strict and secretive ways of the ANBU. He's so used to his more open and brash style, so it's a big change. For example, he might have trouble with the stealth aspect at first.
One plot could be Naruto's relationship with his ANBU superiors. They may initially be skeptical of him because of his reputation as a bit of a wild card. But as they see his determination and skills grow within the ANBU, they start to respect him more. This change in their relationship could lead to Naruto getting more important and dangerous missions, which in turn could further develop his character.
One interesting aspect could be the unique character developments within the fanfic. For example, Naruto might have different relationships with his ANBU comrades compared to the original series. Maybe he has to face more complex moral dilemmas while working in the ANBU, which would add depth to his character.
Maybe there's a threat from a long - forgotten enemy. Naruto, as Hokage, has to mobilize the village's forces, including Sasuke in the Anbu. Sasuke discovers some old secrets related to this enemy that could change the course of the battle. They then have to race against time to use this knowledge to their advantage. This could involve Sasuke going on solo missions within enemy territory while Naruto holds the fort at home and plans the overall strategy.
