Well, Naruto might become more secretive. In his normal life, he shares everything with his friends. But in this fanfiction scenario, the things he experiences with Slenderman might be so strange and hard to explain that he keeps them to himself. His sense of humor could also fade a bit as he's constantly in a state of unease. However, his core of loyalty would still remain, but it might be tested as he tries to figure out how to deal with Slenderman without putting his friends in danger.
His personality might change in a way that he becomes more cautious. Naruto is used to facing his enemies head - on, but Slenderman's nature of being elusive and unpredictable might make Naruto think twice before acting. He could also develop a sense of paranoia, always looking over his shoulder for signs of Slenderman. This would be a big shift from his normal, confident self. He might start to question his own abilities and whether he can really protect his friends in this new and dangerous situation.
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 He could be more withdrawn as he grapples with the strange and often terrifying aspects of Slenderman's world.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 patient. As a dad, he has to deal with his kids' tantrums and mistakes, so patience is key.
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.
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.
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.
In this fanfiction scenario, Naruto's transformation into a Joker fan could lead to some significant changes. Naruto has always been about friendship and protecting his village. But as a Joker fan, he might start to see the flaws in that system. His new - found admiration for the Joker could make him view the power structures in the ninja world as something to be toyed with. He could use the Joker's unpredictability to his advantage in battles, confusing his opponents. However, this would also put him at odds with his friends and the village elders who uphold the traditional values.
Naruto might become more withdrawn like Gaara was initially. Gaara was isolated due to his power and the fear others had of him. So Naruto could start to keep to himself more, losing some of his boisterous and friendly nature.
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.
In this fanfiction, Naruto could turn ruthless in terms of his relationships too. He might cut off ties with those he used to consider friends if he feels they are holding him back. His once warm and friendly attitude towards others could be replaced with a more calculating and self - centered one. He may start using people to achieve his goals rather than working together as he did before.
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.
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.
