Naruto's personality would become more brooding. He would be less impulsive and more calculating, like Batman. He might not be as openly friendly as he was before, keeping his thoughts and plans more to himself.
In a fanfic where Naruto becomes Batman, his personality would undergo a significant shift. He would become more introverted in a sense. His usual exuberance would be toned down. He would be more focused on justice in a more 'dark knight' way. His sense of humor might also change. Instead of his goofy, light - hearted jokes, he might use dry, sarcastic remarks more often. He would be constantly vigilant, and his once carefree attitude would be replaced with a more serious, determined one. This is because Batman's character is defined by his tragic past and his unwavering commitment to justice, and Naruto would have to adapt to these aspects if he were to become like Batman.
His personality would become more reserved. As an assassin, he couldn't be as open and friendly as he used to be. He'd have to keep his emotions in check to avoid being detected.
Naruto's personality would likely become more patient. As a medic nin, he would need to be calm and focused during treatments. His impulsiveness would probably decrease as he realizes that any hasty move could harm a patient. He might also become more empathetic, understanding the pain and suffering of others on a deeper level.
Naruto's normally sunny and optimistic personality would likely become darker. He might be more brooding and less quick to trust. His sense of humor would probably take on a more sardonic edge as the power of Jack of Blades seeps into him.
His positive and determined personality would turn into a cynical and cruel one. He might lose his sense of justice and become self - centered.
Well, Naruto's personality would have an interesting transformation. He would likely become more of a risk - taker. The pirate world is full of uncertainties and dangers, and Naruto would embrace this. He might become more laid - back in some ways, enjoying the simple pleasures of life at sea like drinking grog (if they have something similar in this fanfiction world) and singing sea shanties. But at the same time, his competitive nature would still be there. He'd want to prove himself as a great pirate, perhaps competing with other well - known pirates. His naivete might also change a bit. While he was often naive in the ninja world, the harshness of the pirate life would make him more street - smart, yet still retain his positive outlook on life.
Naruto's personality would change in several ways. He would become more aggressive, which is a big part of Wolverine's character. He might be quicker to anger and less patient. However, he would also have a sense of loyalty like Wolverine. His old self - sacrificing nature would still be there but it would be expressed in a more Wolverine - like way, being more protective and ready to fight for those he cares about without hesitation.
His personality might become more aggressive. The demon nature could bring out his primal instincts, making him less patient and more prone to anger.
He might become more brooding. The new powers and the vampiric nature could make him a bit more withdrawn as he tries to understand and control his abilities. But his core of kindness would still be there.
His confidence would likely soar. Naruto has always been confident, but as the Sorcerer Supreme, he'd have an even greater sense of self - assurance. He'd know he has the power to protect and make a difference on a much larger scale. He might also become more reserved in some ways, as he'd have to deal with more serious magical matters and might not be as quick to jump into action without thinking first.
Naruto's personality could become more complex. He was always an optimist as a ninja, but as a shinigami, he might see the darker side of things more often. However, his core values of friendship and protecting others would remain. He might be a bit more reserved in expressing his emotions as the shinigami world may have different social norms. But overall, he'd still be the same Naruto at heart, just with a different perspective on life and death.
