His sense of loyalty might shift. In the Naruto world, he's loyal to his village and friends. But as Caius Ballad, he might have different allegiances. He could become more calculating in his loyalty, choosing sides based on power and long - term goals. His naivete, which was kind of cute in the Naruto series, might disappear as he takes on Caius Ballad's more jaded view of the world. He'd have to be more cut - throat in the new world he's in.
Naruto's always been this energetic and positive guy. But if he becomes Caius Ballad, he might become more brooding. Caius Ballad has a different kind of vibe, more serious and intense. Naruto's cheerfulness might be toned down a bit, and he could become more focused on achieving specific goals rather than just his general idea of becoming Hokage.
If Naruto becomes involved with Slenderman in a fanfiction, his usually cheerful and determined personality might become darker. He could be more withdrawn as he grapples with the strange and often terrifying aspects of Slenderman's world.
He might become more cautious. As a bounty hunter, one wrong move could cost him his life. So, he would be less reckless than he was as a ninja in some battles. But his core of being kind and believing in second chances would still be there.
Naruto might become a bit more reserved. Since Ulquiorra is a rather cold and stoic character, Naruto could start to hold back his more exuberant emotions. He might also become more analytical, like Ulquiorra, when it comes to combat situations. Instead of charging in head - first all the time, he'd think more about the best approach.
If Naruto becomes like Kenpachi, his personality would become more rough and wild. He would be more direct in combat and less likely to hold back. He might also lose some of his optimistic charm in the process, becoming more of a battle - hungry brute.
Perhaps Naruto's chakra system somehow gets linked to Caius Ballad's power source. This would cause a transformation in Naruto's abilities. He might gain new powers related to Caius Ballad's, like the ability to control certain elements in a different way. And his relationships with the characters in Caius Ballad's world would be interesting to explore. He could make new friends or enemies, and his presence might even change the power dynamics in that world.
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.
His personality might become more cautious. Since he has a greater responsibility as a guardian, he can't be as reckless as he was sometimes in the original Naruto series.
His personality might become more withdrawn. As a lich, Naruto could be feared by others, and this might make him more hesitant to interact with people. He was always so outgoing before, but now he might keep to himself more.
Naruto may also become more solitary. Sparda often fought alone, and Naruto, influenced by this, might start to distance himself from his friends at first. However, he would still have that underlying loyalty and would eventually find a way to balance his new - found independence with his relationships.
His confidence would skyrocket. Gilgamesh is extremely self - assured, and Naruto, if influenced by him, would become even more so. He'd be more outspoken about his own abilities and less likely to doubt himself in tough situations.
