Flashbacks are also a common plot device. The fanfic could show flashbacks of Naruto's past, especially related to his early encounters with the Nine - Tails. These flashbacks could give him insights into how to control the beast. Moreover, the concept of a spiritual connection or a bond with a previous Nine - Tails host could be explored. This connection could transfer knowledge or power to Naruto, enabling him to achieve complete control.
In some fanfictions, Naruto achieves complete control of the Nine - Tails through intense mental training. He might enter a special mental space where he has to face the Nine - Tails directly and prove his worthiness. By showing unwavering determination and a deep understanding of the power, he slowly gains the upper hand.
A typical plot device could be a power - up related to their brotherhood. Since Naruto has his chakra and Trunks has his Saiyan strength, they might discover a new combined power because they are brothers. Also, there could be a time - travel element involved. Trunks is associated with time travel in Dragon Ball, and this could be used in the fanfiction to explain how Naruto and Trunks' relationship came to be. For instance, Trunks could travel to the Naruto universe and somehow become related to Naruto through some time - warped event.
Another plot device is the use of unique Mist village jutsu and traditions. Naruto often has to learn about these in order to navigate the village and rescue the clans. For instance, he might have to understand the significance of certain water - based jutsu or the cultural taboos that could either help or hinder his mission.
In many such fanfictions, the power struggle plot device is used. If Sakura becomes too powerful or tries to assert her dominance in a way that overshadows Naruto and Hinata's relationship or their own achievements, they might start to hate her. For example, if Sakura gets a high - ranking position in the village and starts making decisions that affect Naruto and Hinata negatively, it can fuel their dislike. Another aspect is the character arc plot device. The writer might give Sakura a negative character arc where she becomes more self - centered or greedy, which would make Naruto and Hinata dislike her.
One possible plot development could be that Naruto uses his new - found control of the Nine - Tails to defeat a powerful enemy that was previously unbeatable. He might be able to combine his own ninja skills with the Nine - Tails' power in a more efficient way, like creating new and unique jutsu.
Naruto's friends could also be of great help. Sasuke, despite their complex relationship, might have some knowledge or abilities that could contribute. Sakura, with her medical skills and her growth as a ninja, could support Naruto in his training. And even his other friends like Shikamaru, who is known for his intelligence, could come up with strategies for Naruto to better approach the task of controlling the Nine - Tails. The entire Konoha village in a way could also be seen as a helper, as it provides the environment and resources for Naruto's growth.
In this fanfiction, Naruto probably has to first learn about the nature of the Nine - Tails' power. He may start by exploring his own family history related to the Nine - Tails. Then, he could encounter some challenges like the Nine - Tails' resistance to being controlled. But Naruto, with his determination, might find a way to communicate with it. For example, he could enter his mind - scape and have a direct conversation with the Nine - Tails. This could be a major turning point in his journey to control it.
The consequences for Konoha's economy would also be significant. Rebuilding all the damaged infrastructure would cost a great deal of money. The trade within the village might be disrupted as well, since many of the shops and markets could be destroyed. Also, the ninja academy might have to be closed temporarily if it's damaged, which would affect the future generation of shinobi in Konoha.
Another plot device could be a mind - link or a shared vision. Maybe Naruto has a moment where he links minds with a past Hokage who was an expert in Rasengan. Through this connection, he gains instant knowledge on how to form and use it. It's a more supernatural way of learning compared to the traditional training.
One interesting 'Naruto Gets Nine Tails' fanfiction could be where Naruto has an even deeper connection with the Nine - Tails than in the original series. For example, he can communicate with it telepathically without any chakra interference. Another one might be a fanfiction where Naruto uses the Nine - Tails' power in creative ways to solve problems that the original Naruto couldn't. Maybe he uses it to heal instead of just for combat.
