He might rely on his physical strength and martial arts skills. Naruto is known for his tenacity and determination. Without chakra, he could train his body to be extremely strong, like a super - athlete. He could use his speed and agility to dodge attacks and land powerful punches and kicks.
He could develop some sort of psychic power that doesn't rely on chakra. This could be a power related to his willpower, allowing him to influence the minds of his opponents or sense their intentions from a distance.
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.
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, male characters would have to find new ways to be relevant. Shikamaru, for instance, would probably enhance his strategic thinking even more. Rock Lee might become a role model for male characters as he already focuses on non - chakra - based Taijutsu. Female characters could experience a boost in confidence. Ino could develop her mind - control abilities further, now that she has more of a spotlight with males out of the chakra - using picture. And Tenten could become a master of non - chakra weapons, leading the way for other female characters.
Well, it would change the plot drastically. Males usually play a major role in using chakra in Naruto. Without male chakra users, female characters would have to step up more. For example, Sakura might become the lead in battles more often, and the whole power dynamic in the ninja villages would shift. Shinobi training for males would also be different, focusing more on non - chakra related skills like physical combat and strategy.
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.
If Naruto couldn't use chakra, the entire story would be drastically different. Firstly, he wouldn't be able to perform his signature jutsus like the Rasengan. His training with Jiraiya would also take a different turn as they couldn't focus on chakra - based skills. Without chakra, Naruto might have to rely more on his physical strength and strategic thinking. He could develop unique fighting styles that don't involve chakra, perhaps something similar to real - world martial arts. This would also change his relationships. For example, Sasuke, who is very chakra - powerful, might view Naruto in a different light. It could lead to a more complex and less predictable plotline.
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.
He would become more reliant on his friends and allies. Since he doesn't have chakra to fall back on, he has to trust others more and learn to work in a team in a different way.
