Naruto himself would probably be one of the main ones. He's always been associated with powerful chakra use in the original series, and in this fanfiction, with only males using chakra, he would stand out even more. Another could be Sasuke. His chakra abilities are also quite remarkable, and he would be a key male character in terms of chakra use in this fanfiction.
Well, it could limit the power dynamics in the story. Since only males can use chakra, female characters might have to rely on other skills or abilities. This could lead to a more distinct separation between male and female roles, with males being the main fighters due to their chakra use.
Yes. In Naruto fanfiction, the idea of Naruto being the first male born with chakra can be a very unique concept. It could potentially change many aspects of the original Naruto story. For example, his relationships with other characters might be different as they would view him as an even more special existence. His training and development might also take on new directions since his connection to chakra is so distinct.
In some fanfictions, Naruto might use chakra strings in a similar way to how Sasuke uses his chakra to control his sword. He could send out his chakra in the form of strings to manipulate objects from a distance. For example, he could use them to pull weapons out of an enemy's hand or to tie up an opponent.
In some fanfictions, Naruto might learn to use chakra chains through special training. Maybe he discovers a new form of chakra control or he is taught by a mysterious character who has knowledge of this unique ability.
He might have an enhanced ability to control chakra. Maybe he can access chakra reserves more easily and use it more efficiently than others. His jutsu could be stronger and more effective.
Sasuke Uchiha could be one. Since he has the Rinnegan in the later parts of the Naruto series, it's possible that in fanfiction he could be using chakra chains in connection with his Rinnegan powers. Another could be Naruto Uzumaki if the fanfiction has some kind of plot twist where he also gains access to the Rinnegan and uses chakra chains in a new and unique way.
Well, it depends on the specific fanfiction. Some fanfiction writers might choose to incorporate the concept of Chakra into Percy Jackson's world. They could create a scenario where Percy discovers a way to access and use Chakra, perhaps through some kind of magical cross - over event. However, not all fanfictions will do this as different writers have different ideas and directions for their stories.
One more plotline could be that Naruto uses his unique chakra to form a new kind of ninja art. Since he is the only male with this chakra, he has the potential to create something that has never been seen before in the ninja world. This new art could be a combination of his unique chakra properties and his own creativity. It might start as an experiment, but as he hones it, it becomes a powerful tool that not only helps him in battles but also changes the way ninja warfare is perceived. His friends might be initially skeptical, but as they see the potential, they join him in exploring and perfecting this new art.
He might rely on his physical strength and martial arts skills. Just like Rock Lee in the original series who doesn't have much chakra but is a great fighter through intense physical training.
