One example could be a fanfic where Naruto pretends to be a weak genin even during the Chunin Exams. He might let others underestimate him while secretly observing his opponents' moves and strategies. This allows him to surprise everyone when he finally reveals his true power during a crucial battle.
In some fanfictions, Naruto hides his power to protect his friends. For instance, he might hide the fact that he has already mastered advanced jutsu because he doesn't want his enemies to target his friends in order to get to him. By acting weaker than he is, he can keep his loved ones out of harm's way.
There are fanfics where Naruto hides his power because he wants to understand the true nature of those around him. He might believe that if people know how powerful he is, they will only be nice to him because of his strength. So, he acts as a normal ninja, and in the process, he discovers who his real friends are and who are just using him.
One idea could be that Naruto hides his power to protect his loved ones from being targeted. For example, if his enemies knew his true strength, they might go after Hinata or Iruka. Another could be that he's hiding it as part of a long - term strategy to overthrow a greater evil that is secretly observing the ninja world. Maybe he wants to lull them into a false sense of security before making his big move.
Well, one possible plot could be that Harry hides his power to protect his friends from dark wizards who might target them if they knew how powerful he really was. Another could be that he hides his power to secretly investigate a mystery within Hogwarts without drawing attention.
Perhaps he has hidden the full extent of his Sage Mode abilities. He might be able to stay in Sage Mode for a much longer time than he has shown so far, or have some other undisclosed powers within that mode, like the ability to sense enemies from much greater distances.
In some fanfictions, Naruto's hidden power could be the ability to control a powerful and ancient force. For example, he might be able to harness the power of some long - forgotten bijuu or a mysterious energy that was sealed away in the past. This would give him abilities that are on a completely different level compared to his normal skills.
In a Peter hides his identity fanfiction, he might use advanced technology to conceal who he really is. For instance, he could have a holographic device that changes his appearance completely. This allows him to move freely among his enemies without being recognized. The story could explore the moral dilemmas he faces while keeping this big secret from his loved ones.
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.
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.
One example could be a fanfiction where Naruto becomes obsessed with power to the point of challenging all the great shinobi in the world without hesitation. He might seek out forbidden jutsus and train in isolation to gain more power, disregarding his friends and the village at first.
He could be using basic chakra control techniques to suppress his power. By constantly regulating the flow of his chakra, he can keep his true power hidden. For example, he might be using a form of internal chakra suppression similar to what some ninja use to hide their presence.
Obviously, Harry Potter is the main character as it's about him hiding his power. His friends, like Hermione Granger and Ron Weasley, are also likely to be main characters. They might be in the dark about his hidden power at first, which could create some interesting dynamics in their relationships.
