One possibility is that there's some ancient chakra or energy in Wave that interacts with Naruto's own chakra. The unique environment of Wave, with its water and nature elements, might have caused his Mokuton to awaken. Another reason could be that Naruto has some kind of connection to the First Hokage that gets revealed during the Wave mission, and that connection enables the Mokuton awakening.
In the 'Naruto awakens Mokuton in Wave' fanfiction, there could be several reasons for his Mokuton awakening. It could be related to the strong emotions he experiences during the mission. For example, his determination to protect Tazuna and his friends might stir something deep within him. Additionally, there might be a secret jutsu or artifact in Wave that has an impact on Naruto's chakra, causing the Mokuton to emerge. Or perhaps the author just wanted to give Naruto a new and exciting power - up for the sake of the story, making the Wave mission more interesting and full of unexpected twists.
When Naruto awakens Mokuton in the Wave fanfiction, his role in the Wave mission is transformed. Mokuton is a powerful and versatile ability. Naruto could use it to camouflage the group by creating a forest - like environment, making it harder for the enemy to find them. He could also use wooden constructs to hold off attackers while the others carry out the main objective of the mission. This new power elevates his status from a novice ninja trying to prove himself to a crucial part of the mission's success.
One potential antagonist could be Orochimaru. He might be interested in Naruto's Mokuton powers for his own evil experiments. He could try to capture Naruto to study how he awakened the Mokuton and use that knowledge for his own gain.
Well, one possible plot development could be Naruto using the Mokuton ability to create large forest defenses during battles. For example, he might grow thick trees around his village to protect it from invaders.
Another plotline might involve Naruto being ostracized because of his new Mokuton power. Since it was associated with the Uchiha and Senju in a complex way, some in the ninja world might suspect him of having ulterior motives. This would lead to Naruto having to prove himself all over again, this time not just as a jinchuriki but also as a wielder of Mokuton.
One possible reason could be jealousy. If Naruto has the rare Mokuton ability, his family might be jealous of his potential power and neglect him out of spite.
There could be a plotline where the character with Mokuton is constantly compared unfavorably to other family members with different abilities. This leads to the character feeling inferior and trying to prove themselves. As the story progresses, they might discover a unique aspect of Mokuton that makes it even more powerful than expected. This newfound knowledge could be the key to not only getting the family's respect but also to solving a major problem in the Naruto world, like a powerful enemy threat or a natural disaster.
One implication is that he becomes much more powerful. The Rinnegan gives him access to powerful abilities like the Six Paths techniques, which would change the power dynamics in battles in the fanfiction. He could now face stronger enemies more easily.
One popular fanfiction concept could be Naruto discovering he has Mokuton abilities during a battle. Maybe he's facing a powerful enemy and suddenly, the Mokuton powers awaken within him, giving him an edge with the ability to create and control wood. This could lead to him having to learn how to master this new power quickly while still in the heat of combat.
In the fanfiction world where Naruto has inborn Mokuton, his training could start very early. Since Mokuton is related to nature, he could train in the forest, learning to communicate with the trees and draw out their power. He might be taught by an ancient spirit of the forest that only reveals itself to those with Mokuton. This spirit could show him how to infuse his chakra into the earth to make plants grow instantly. As he grows older, he could train with other powerful ninja who have nature - based jutsu to learn how to combine Mokuton with other elements. For instance, using wind to spread the seeds of his Mokuton - created plants further and faster.
I'm not entirely sure as there could be many different stories with that title. It might be about a character in Naruto who has the Mokuton (wood - style) ability being banished from their village or group.
