A really interesting secret jutsu in Naruto fanfic could be the 'Energy Absorption Jutsu'. This jutsu enables the user to absorb any form of energy, whether it's chakra - based attacks or natural energy from the surroundings. It gives the user a huge advantage in battle as they can then use the absorbed energy to power up their own attacks. There might also be a 'Teleportation Gate Jutsu' which creates multiple gates in different locations that the user can instantly teleport between. And the 'Aura Manipulation Jutsu' where the user can manipulate their own chakra aura to have different effects, like creating a shield or enhancing their physical abilities.
Sure, there are jutsus aplenty in the Naruto manga. They range from elemental jutsus like Fire Release and Water Release to powerful sealing techniques. These jutsus play a crucial role in shaping the battles and character development within the manga.
In Naruto fanfiction, forbidden jutsus often include things like the Edo Tensei in a more extreme or modified form. However, it's important to note that adult fanfiction may contain inappropriate or non - canon elements that deviate from the original Naruto story. So, it's better to focus on the official Naruto lore for a more accurate understanding of jutsus.
Naruto might develop a 'Force - Shadow Clone Jutsu'. He could use the Force to create shadow clones that are more durable and have some Force - related abilities. For example, they could use the Force to sense enemies or even share knowledge between each other more effectively.
In fanfic, Naruto might have the power to control time. This could be used to go back and change crucial events in the ninja world. For example, he could prevent the destruction of his village in the past.
The Rasengan is one of his signature and very powerful jutsus. It is a spinning ball of chakra in the palm that can cause great damage.
Well, he might start with intense training sessions. Maybe he observes Kakashi closely for the Chidori, and for the Rasengan, he practices over and over again, gradually getting the hang of the chakra control required.
For Hinata, Naruto might create a jutsu that helps her enhance her Byakugan's range and clarity even further. It could also have a defensive aspect where she can project a shield made of chakra visible only to those with the Byakugan. For Shino, a jutsu that makes his bugs more resistant to enemy jutsus and also gives them the ability to track opponents over long distances. For Sasuke, a jutsu that combines his fire - based attacks with lightning in a more seamless way, creating a new and more powerful element.
One jutsu he could invent is the 'Elemental Mimicry Jutsu'. With this, Naruto could temporarily take on the properties of any element he has encountered. For example, he could become as fluid as water to slip through attacks or as solid as earth to withstand powerful blows.
One possible amazing plotline could be the main character having some god - like powers that they have to hide in high school to avoid unwanted attention. Maybe they use these powers secretly to protect their friends from bullies.
One possible plot could be that Naruto becomes an all - powerful ninja who uses his knowledge of all jutsus to bring peace to the ninja world. He could travel from village to village, teaching the jutsus to others and uniting the different ninja clans.
