In some fanfiction, there is a secret jutsu that combines all of Naruto's chakra natures into one super - powerful attack. This jutsu might be called something like 'The Unity Blast'. It's often used to defeat extremely powerful enemies that normal jutsu can't handle.
One interesting Naruto secret jutsu in fanfiction could be a time - traveling jutsu. It allows Naruto to go back in time and change certain events in the ninja world. This can lead to all kinds of new storylines and character developments.
It could be a new form of Rasengan. Maybe Naruto discovers a way to combine different elements with the Rasengan more effectively, like adding lightning to it for a more powerful and faster attack.
Maybe Sasuke. Although they are rivals, they also have a deep bond. Sasuke might have come across a unique jutsu during his travels and decide to teach it to Naruto so that they can both become stronger and better protect their village.
There could be a jutsu that allows for instant teleportation across long distances. This jutsu might be a new discovery in the fanfiction world, perhaps created by a character who has been experimenting with space - time ninjutsu. They might use it to quickly get in and out of battles or reach far - off places in a blink.
He might learn a time - traveling jutsu. This would be really cool as it could allow him to go back and change certain events in the Naruto world, or gain knowledge from the past to use in the present battles.
One interesting idea could be exploring new and unique ways the expansion jutsu can be used in battles. For example, using it not just for physical size increase but also for expanding the range of other jutsus.
In 'Naruto hair jutsu fanfiction', a really cool concept could be the combination of different elements with hair jutsu. For instance, fire - infused hair that can cause more damage in attacks. Or water - based hair jutsu that can be used to either douse fires or create barriers. There could also be the idea of using hair jutsu to enhance the user's speed or agility. By using their hair in a certain way, they can move faster or change directions more quickly.
Well, in 'naruto hiraishin no jutsu fanfiction', there might be the concept of different generations learning and evolving the jutsu. Maybe a new character figures out how to make the Hiraishin no Jutsu faster or more accurate. Also, some fanfictions could explore the idea of using the jutsu in non - combat situations, like for quick transportation across long distances in a more peaceful world.
One interesting plotline could be a character other than Minato or Tobirama mastering the Hiraishin no Jutsu and using it in unexpected ways. For example, a young genin discovers a hidden scroll about the technique and through sheer determination and some lucky breaks, manages to learn it. This could lead to a whole new set of adventures as they try to keep it a secret from the wrong people while also using it to help their friends.
One interesting aspect could be the creative interpretations of Naruto's jutsu in a different, albeit perverted, light. However, it's important to note that such fanfiction often strays from the original positive and moral themes of the Naruto series.
In some fanfictions, the Harem Jutsu plotline involves Naruto accidentally using it on a group of powerful female ninja who then become obsessed with him. This leads to all sorts of chaos as Naruto tries to figure out how to reverse the effects while also dealing with the newfound attention. And there are also fanfictions where the Harem Jutsu is enhanced by some magical or mysterious force, making it even more powerful and unpredictable.
