It could also be related to his sense of self - preservation. Naruto may be aware that there are forces in the village that are not entirely friendly towards him. If he shows his full power in the academy, it might alert those who have ill - intentions towards him. He may not be fully confident in his ability to protect himself against all potential threats at that time, so he holds back to avoid putting himself in unnecessary danger.
Perhaps Naruto is waiting for the right moment. He could be observing his classmates and the teachers in the academy to figure out who he can really trust. By holding back his power, he can better assess the situation and the people around him without revealing his full capabilities too soon. Also, he might not want to disrupt the normal order of the academy. Naruto might have a sense that if he goes all - out, it could cause chaos and that's not what he wants at this stage.
Well, it might initially make his classmates underestimate him. They could see him as just an ordinary or even a bit of a weak student. This might lead to some of them treating him casually or even bullying him. However, for those who are more perceptive, like Sasuke, they might sense that there is more to Naruto than meets the eye, which could pique their curiosity.
Well, in this type of fanfiction, Naruto could change the relationships he had at the academy. He may befriend Sasuke earlier and in a different way, perhaps preventing Sasuke from being so cold towards him initially. Also, he could have more time to train with his classmates and help them improve too, which would make for a very different dynamic in the group.
One possible reason could be that Ash senses a dangerous situation where Pikachu's full power might attract unwanted attention or put them in more danger. For example, if there are powerful and unseen enemies nearby, Ash might hold Pikachu back to keep a low profile.
There were many choices for novels like Back to Ancient Times and Open an Academy. The following are some recommended novels: " My Family Fleed from Famine " by Yan Ruxu;" Dressed as a Widow, Raising Children and Farming in Ming Dynasty;" Cultivation is Endless;" I Really Don't Want to Take a Short Cut Again " by Lin Shanhai;" Halfway Empress " by Unknown;" Traversing to the Ancient Academy to Become a Charming Man Forced to Shura " by Unknown. These novels all had the plot of traveling back to the ancient academy, which could satisfy the readers 'interest in this subject.
Another possibility is that Naruto has his own plans and goals that he wants to achieve independently. His true power might be a key factor in these plans, and he doesn't want his parents' influence or interference. He wants to prove himself on his own terms, without relying on his family connection.
Well, Naruto could show Boruto his Sage Mode power. Sage Mode gives Naruto enhanced strength, speed, and the ability to sense chakra more acutely. It's a very powerful form that Naruto has mastered over time. By revealing it to Boruto, he might be teaching Boruto about the different levels of power and the hard work required to achieve such power.
It could be a new character. Maybe a powerful ninja from a far - off land who has heard rumors of Naruto's strength and is determined to draw it out and defeat him to prove his own superiority. This antagonist might be secretly spying on Naruto and trying to find ways to force him to show his true power.
There are fanfictions where Naruto's power is shown through his ability to connect with the spirits of past Hokages. With their combined wisdom and his own strength, he's able to perform a super - powerful jutsu that not only protects Konoha but also restores the balance of the ninja world. He uses this new - found power to face an ancient evil that has been awakened.
Boruto might be in awe. He would probably look at Naruto with wide - eyed wonder, realizing just how powerful his father is.
Obviously Naruto is one of the main characters since it's in the title. But there could also be his friends like Sasuke and Sakura. They might play important roles in understanding why Naruto is holding back and how they can help him overcome this issue.
