Maybe it's a time - based element. Naruto could use this new element to manipulate time in a limited way. For example, he could slow down time for his opponents during a fight, giving him an edge. This would add a whole new dimension to his combat abilities.
Perhaps it's through a special encounter. He could meet an ancient being or a powerful sage who reveals the existence of this new element to him. The being might see Naruto's potential and decide to guide him in unlocking this new power. This would also introduce new characters and lore to the fanfic.
Well, in a way it might be. It adds an element of modernity or an alternate universe feel. However, some purist fans might not like it as it goes against the original setting. But it also allows for creative crossovers, like if Naruto was in a more modern or post - apocalyptic world where guns are common.
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.
I recommend "The Strongest Berserker Monster System", a fantasy novel from the East. The male protagonist uses the monster system to obtain various cards and abilities. There are levels and card elements, and there are also characters such as swordswomen. I hope you like this fairy's recommendation. Muah ~😗
Well, in the fanfic, Naruto using crystal release could be part of a mission. Maybe he's in a land where crystal release is common among the enemies. He starts to study their techniques and somehow manages to adapt it to his own style. He could then use it to save his friends during a really tough fight. Like, he creates a huge crystal shield to protect everyone from a massive attack and then turns the shield into sharp projectiles to counter - attack.
In a fanfic where Naruto uses haki, it could change his relationships with other characters too. For example, if he shows this new power, some characters might be in awe of him, while others might be jealous. His training to master haki could also lead to new interactions with mentors or allies who are familiar with this power. Also, his use of haki could potentially attract the attention of new enemies who are interested in this unique ability.
One possibility could be a 'Lightning - Fire' hybrid element. Naruto might discover it during an intense battle where he tries to combine his Rasengan (which has a spinning, chakra - based nature) with both his Lightning Style and Fire Style techniques. He realizes that by carefully mixing the raw power of Lightning and the intense heat of Fire, he can create a new element that has the ability to cut through almost anything like Lightning, but also has the burning power of Fire.
Naruto could potentially have the ability to create ki - based shields. These shields could protect him from various attacks, whether they are physical or energy - based. Another new ability could be ki - infused clones. Instead of just normal clones made of chakra, these clones would have an added ki element, making them stronger and more durable. He might also be able to use ki to heal himself faster, similar to how some characters in other stories use life - force energy for regeneration.
