What are the possible scenarios of Naruto training alone after the Wave mission in fanfiction?

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.

One possible scenario could be that all of Naruto's friends are killed in a great battle. He survives but is left alone, haunted by the memories of his lost comrades. He might then wander the world, a solitary figure, with his only company being the memories of the past.

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.

Well, in a 'Naruto has secret mission' fanfiction, Naruto could be tasked with establishing an alliance with a reclusive and powerful clan. This would require him to prove himself worthy and overcome their initial distrust. He may also be on a mission to find a long - lost jutsu that could change the balance of power in the ninja world, and he has to keep it a secret from other villages to prevent a scramble for it.

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.

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, 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.

He could become more empathetic. After seeing the suffering in Wave, Naruto might be more in tune with the pain of others. So when he meets people in similar situations later, he can better understand their feelings.

There could be a scenario where Naruto doesn't really understand the significance of the kiss at first. But Hinata is deeply affected and starts avoiding Naruto. This makes Naruto wonder what he did wrong and he tries to find out. As he tries to figure things out, he starts to realize his own feelings for Hinata might be more than just friendship. In some fanfictions, this also might attract the attention of other characters who have an interest in either Naruto or Hinata, causing some jealousy and drama.
