When Naruto gets Madara's power in fanfiction, his character undergoes a significant transformation. He becomes more reserved in some ways. He realizes the weight of the power he now holds, which is different from his own natural abilities. He also becomes more strategic. Naruto was always a bit impulsive, but with Madara's power, he has to be more careful. He starts to think like Madara in terms of long - term planning for battles and for the safety of the ninja world. His relationships change too. Some characters might be a bit intimidated by him now, while others would look to him for leadership even more than before.
His confidence would skyrocket. Naruto has always been confident, but with Madara's power, he'd have a new level of self - assurance. He'd know he could handle almost any threat. His sense of responsibility would also grow. Since he has such great power now, he'd feel an even greater obligation to protect his village and friends.
Some of his friends might be a bit more cautious around him. For example, Sasuke might be more on guard, as he has a history with the Uchiha and Madara's power is something he'd be very aware of. But Naruto would still try to keep their friendship intact.
He becomes more aggressive. Usually, Vegeta is already a rather aggressive character, but when jealous, he can be over - the - top. He might start unnecessary fights or challenges, just to assert his dominance. For example, if he's jealous of someone getting close to Bulma, he might challenge them to a fight without any real provocation.
Naruto's character would become more complex. He'd have to deal with the power and the history associated with Madara's eyes. This might make him more cautious as he realizes the potential danger of the power he now holds.
His power level would skyrocket. He could get access to Kami's knowledge and abilities, which would make him extremely powerful in the ninja world.
It also depends on how well Naruto can control Kyoka Suigetsu. If he can master it completely, his power level could skyrocket. However, if he struggles with it, it might not be as much of an increase. There could be a learning curve where he initially has trouble using it effectively, and during that time, his power level might not show a huge jump. But as he gets more experience with the sword, his power would grow steadily, making him a force to be reckoned with not just in physical combat but also in the mental battle of illusions.
He becomes more aggressive. His friendly nature is gone and he's quick to lash out.
Naruto's character would change in several ways. Firstly, he would become more strategic. As a lord, he has to plan for the long - term development of his land, which requires thinking ahead. His impulsiveness would be curbed as he has to deal with the complex web of politics. He would also grow in terms of wisdom. He would learn from his experiences and the advice of his advisors. His charisma would be used in a different way. Instead of just inspiring his ninja comrades, he would need to inspire all his people. His sense of justice would expand from individual cases to the overall fairness of his domain, and he would strive to make his territory a model of a just society.
He becomes more serious. Gone is the Naruto who is always cracking jokes.
If Naruto gets Madara's power in fanfiction, he would become extremely powerful. His already impressive combat skills would be enhanced to a whole new level. He could use Madara's Sharingan abilities, which would give him an edge in predicting his opponents' moves. Also, Naruto might be able to access Madara's unique jutsu, like the Susanoo. This would make him a nearly unbeatable force in the Naruto universe of the fanfiction, and it could potentially change the entire power dynamic among the characters.
His loyalty shifts. Normally, Naruto is extremely loyal to his friends and village. But when brainwashed, he might turn against them. For example, he could start working for the enemy, believing that what they are doing is right.
