His sense of justice could be warped. Naruto has always fought for what he believes is right, but as a Darkseid fan, he might start to think that power is the ultimate arbiter of right and wrong. This could lead him to make decisions that are more self - serving rather than for the good of the village. For example, he might pursue power at all costs, even if it means sacrificing the safety of his friends in the short term to gain more strength in the long run. He would become more calculating and less impulsive in his actions, which is a big change from his usual head - first style of dealing with problems.
Naruto's confidence could turn into arrogance. He has always been confident in his abilities, but as a fan of Darkseid, he may overestimate his own power and importance. He could start to look down on those he once considered equals or friends, believing that he is on a higher path because he is exploring Darkseid's ways. His relationships would likely suffer as a result, and he would find himself more isolated as he distances himself from the people who care about him, all in the pursuit of emulating the dark and powerful Darkseid.
Batman's personality would be radically different. He would be more power - hungry. Growing up with Darkseid, he would see power as the ultimate goal. He'd be less empathetic and more about achieving dominance, not justice.
Naruto's view on leadership could shift. Byakuya is a respected figure in his own world. Naruto, as a fan, could start to adopt some of Byakuya's leadership traits, such as being more decisive and less likely to second - guess his decisions. He would also become more aware of the importance of setting a good example for those around him, just like Byakuya does in his own group.
Naruto would probably become more serious. Future Trunks has a very serious and determined personality due to the hardships he has faced. Naruto, being a fan, might adopt some of that. He could be more focused on long - term goals and less impulsive in his actions.
Naruto would probably have a more complex view of power. In the original, he was all about becoming stronger to protect his friends. But as a Darkseid clone, he might question the nature of power. Darkseid uses power for domination, and Naruto would have to struggle not to be influenced by that aspect while still using his new - found powers for good.
If Naruto were on Team 8 in fanfiction, his personality could develop in several ways. He may become more empathetic as he gets to know his new teammates better. Hinata's shyness might make him more sensitive to others' feelings, and he would try to encourage her more. Also, being around Shino's quiet and methodical nature could make him more reflective. He might start thinking more about the consequences of his actions before acting, which is a big change from his usual impulsive self. He could also become more competitive in a different way, trying to prove himself not just in combat but also in the more specialized skills that Team 8 values, like tracking and espionage.
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 become more calculating. While he's always been headstrong, as a mafia boss, he'd have to think several steps ahead. He couldn't just rush into things like he did in his ninja days. He'd still be loyal, but that loyalty would be more towards his mafia family. His cheerful and sometimes naive side would probably fade a bit as he'd be dealing with more underhanded and dangerous people. He'd need to be more secretive and not show all his cards at once.
His personality would likely be more subdued. Ebisu is a rather proper and disciplined character, so Naruto would probably be less rambunctious.
He might become more wild and instinctive. Tailed beasts are known for their raw power and basic instincts. So Naruto could be more impulsive, acting on his first thoughts rather than thinking things through. For example, in a fight, he might not hold back as much as he usually does as a normal ninja.
He would probably become more diplomatic. Naruto is already good at making friends, but as a Daimyo, he would need to be more tactful in his interactions with other leaders. He would have to hold his tongue more and think before speaking to avoid international incidents.
