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 Instead of his usual cheerful self, the dark chakra might cause him to be more withdrawn as he grapples with this new power within him.
His once optimistic and determined personality would turn cynical. Instead of seeing the good in people, he would suspect everyone. For example, he would no longer trust his friends easily. His sense of humor would disappear, replaced by a cold and sarcastic attitude. He would become more secretive and withdrawn, not sharing his thoughts and feelings like he used to.
Naruto as a god in the fanfic could be more confident and less impulsive. His new powers and status may give him a sense of calm and wisdom that was lacking in his younger self. He may make decisions more rationally, thinking about the long - term consequences for the entire world rather than just his immediate surroundings.
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.
His view of the world could change. Dark Naruto might have carried some resentment or a different perspective on the ninja world. After absorption, Naruto may start to see things from a more cynical angle at first. However, as he grows and reconciles with this new part of himself, he could end up with a more balanced view that takes into account both the positive and negative aspects of the ninja world. This could lead to him making different decisions in how he approaches problems and interacts with others.
Well, it could change the plot in many ways. For example, he might be able to defeat stronger enemies more easily. If he can absorb chakra during battles, he can quickly replenish his own and keep fighting without getting tired as fast. This would make him a more formidable opponent and might change the power dynamics in the story. Maybe he could even absorb the chakra of some of the main villains, which would completely disrupt their plans and change the course of the overall plot.
Well, with infinite chakra, Naruto can spam his powerful jutsus without getting tired. For example, he could keep using Rasengan continuously. This would make him almost unbeatable in battles, changing the power dynamics in the story completely.
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.
His character changes in terms of his trust. He was always eager to gain the villagers' trust before, but after being blinded by them, that trust is severely damaged. He may become more guarded and less likely to open up easily. Also, his sense of justice might be more intense. He could be more driven to fight for the rights of those who are wronged, since he has now been a victim himself. He might also develop a deeper sense of empathy for others who have suffered at the hands of the unjust.
He might become more withdrawn. Instead of being the energetic and enthusiastic Naruto we know, he could start to isolate himself from others.
Once Naruto masters Kurama's chakra in the fanfiction, his fighting style is revolutionized. He is no longer just relying on his regular ninja skills. The Kurama chakra infusion allows him to enter a more powerful state. He can now use the chakra to boost his jumps, making him able to cover large distances in a single leap. His attacks also carry a new level of ferocity. He can channel the Kurama chakra into his weapons, if he uses any, to make them more effective. Moreover, he can use the chakra to create a sort of protective aura around him, which can deflect or absorb some weaker attacks. This all - around improvement in his fighting capabilities makes him a formidable force in the fanfiction world.
