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.
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.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
Besides Obito, Sasuke could be a main character in this fanfiction. Sasuke, with his own journey of redemption and his understanding of power and the ninja world, could have an interesting dynamic with the reincarnated Obito. Also, Sakura might play a role. She could be the one who tries to heal the reincarnated Obito, both physically if he is injured during his new adventures and emotionally from the traumas of his past life.
Often, Obito is attracted to Kushina's strength and kindness. He might try to impress her with his own abilities. Their interactions could involve Obito being a bit clumsy in his attempts at first. Kushina, on the other hand, might find his eagerness endearing and start to open up to him more. They could share stories about their pasts, their dreams, which deepens their bond.
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.
Obito's influence would likely make Naruto more aware of the darker side of the ninja world. Naruto is usually very optimistic, but with Obito's guidance, he would see the hardships and betrayals that can happen. For example, Naruto might become more cautious in his trust of others.
Well, in Naruto fanfiction, creating new jutsus is a creative process. Some ninjas could create jutsus based on their emotions. For instance, a ninja who has experienced great loss might create a jutsu that is related to grief, like a jutsu that summons dark energy. Additionally, ninjas can also create jutsus by collaborating with others. Two ninjas with different elemental affinities could work together to create a combined - element jutsu. And sometimes, it's just pure inspiration from a dream or a vision that a ninja has, which then leads to the development of a new and unique jutsu.
