In this kind of fanfiction, Naruto's character would experience a significant transformation. He would no longer have to struggle with the limitations that his original chakra levels imposed on him. This could lead to a more carefree and adventurous Naruto. He could be more open to taking risks and exploring new possibilities. His attitude towards training might also change. Instead of focusing on conserving chakra during training, he could focus on pushing the boundaries of his jutsus to their maximum potential. His growth as a ninja would be exponential, and he would likely be seen as a legend in the making much sooner than in the original story.
Naruto would likely become more confident. With infinite chakra, he would no longer have the insecurities related to running out of chakra during battles. This new - found power could also make him a bit more reckless at times, as he might think he can handle any situation without consequences.
If Naruto had no chakra in fanfiction, the story would be completely different. He couldn't use jutsus like the Shadow Clone Jutsu which was so crucial in his development. His journey to become Hokage would have to rely on other aspects like his physical strength and strategic thinking. He might train in different martial arts forms or focus more on weaponry. Maybe he'd become an expert in stealth and espionage without relying on chakra - based techniques for infiltration.
The addition of Hashirama's chakra to Naruto in the fanfiction would be a game - changer for his abilities. Firstly, his stamina would likely skyrocket. Hashirama was able to fight for long periods without tiring, and Naruto could inherit this. Secondly, his sensory abilities might improve. Hashirama had a good sense of his surroundings, and Naruto could use this to detect enemies from a greater distance. Thirdly, his rasengan and other chakra - based attacks could be infused with the unique properties of Hashirama's chakra, making them more powerful and perhaps having additional effects like being able to break through stronger defenses more easily.
It could make him more brooding. Instead of his usual cheerful self, the dark chakra might cause him to be more withdrawn as he grapples with this new power within him.
In fanfiction, the dark chakra can make Naruto more brooding. Instead of his usual optimistic self, he becomes more withdrawn as he struggles with the new power. For example, he may question his own identity and whether he can still be the hero everyone expects him to be.
If Naruto had the devil trigger in a fanfiction, it would change his character a great deal. His usual carefree and optimistic attitude could be replaced by a more cautious and sometimes even menacing one when the power takes over. He would constantly be at war with himself, between his normal self and the self that the devil trigger brings out. His relationships with his friends might also change. Some might be more wary of him, while others would try to help him through this transformation. And he would have to re - evaluate his ninja way in the face of this new and powerful force inside him.
In a Naruto fanfic where he's made of chakra, his growth and development would be unique. He might not need to eat or sleep in the same way as normal humans in the Naruto world. This could free up a lot of time for him to train or explore. Also, his connection to nature chakra could be even stronger, as he is already a being of pure chakra. This could lead to him developing new and powerful Sage Mode variants that are exclusive to his chakra - made form.
Naruto might become more confident. With the new power of chakra chains, he has an extra tool in his arsenal. This could make him bolder in battles and more assertive in his decisions.
Naruto would become more cautious. He has a child to protect now, so he can't be as reckless as he used to be. He'd be more of a planner, thinking about the future and how his actions will affect his child.
Well, it could be that Naruto discovers an ancient artifact that contains Hashirama's chakra. When he touches it or unlocks its power in some way, the chakra gets transferred to him. For example, the artifact might be hidden in a secret location and Naruto stumbles upon it during one of his adventures.
Naruto's character might become more brooding and mysterious, like the Undertaker. He would lose some of his usual exuberance and become more focused on intimidation. Instead of his loud and energetic self, he would be quieter, with a more menacing presence.
