In some fanfictions, Naruto becomes more confident after the Wave Mission. He realizes his own strength and the importance of his friends more deeply. For example, he might be more assertive in battles and decision - making.
Perhaps in this fanfiction, Naruto and his friends go back to the Wave Country for a follow - up mission. This time, they discover a new threat that is related to the power struggle they witnessed during the first mission. The group has to use their improved skills and teamwork to face this threat and protect the people of Wave.
In some fanfictions, Sakura might become more confident after the Wave mission. She realizes the harshness of the ninja world and starts to train harder, not just relying on her teammates. For example, she could be seen spending more time in the hospital, learning advanced medical ninjutsu to be more useful in future battles.
The main antagonist could also be a corrupt official within the Wave Country itself. After the events of the first mission, this official could have risen to power and now has plans to use his position to gain more control, even if it means going against Konoha. He could be secretly working with other villains or using his own resources to create problems for Naruto and his friends.
One common change is that he becomes more serious. He realizes the gravity of being a ninja. For instance, he may not joke around as much during missions.
In some fanfictions, Naruto might focus on improving his chakra control. He could practice by trying to walk on water or climb trees without using his hands, just like he did during his early training with Kakashi. This would help him become more proficient in using his chakra for various jutsus.
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.
Well, in certain fanfictions, Naruto's view of the ninja world as a whole can shift after the Wave arc. He might start to question the traditional ninja values. Since he witnessed the greed and corruption that led to the problems in Wave, he could strive to change the ninja world from within. He may begin to form his own ideas about what it truly means to be a ninja, which could be different from what he was taught at the academy. He could try to promote peace and cooperation more actively, rather than just following orders blindly.
In this fanfiction scenario, Naruto might use his natural empathy. He could start by simply listening to the ANBU's experiences during the mission. Naruto has been through many tough battles himself, so he can relate. He might offer words of encouragement like 'You did your best, and that's what matters.'
In this fanfiction scenario, Naruto might use his unique abilities like the Rasengan to heal the ANBU members. His chakra control, which has improved over time, could be used to mend their wounds. Maybe he also shares some of his Nine - Tails' chakra to boost their energy levels.
