His character could become more complex. The use of a gun might bring out a new side of him that is more calculating. He has to think about ammunition, range, and accuracy, which is different from his usual melee - based combat. This could make him seem more like a strategist, while still maintaining his core heroic values. For example, he might start to analyze situations more carefully before jumping into action, as he knows the power and limitations of the gun he's using.
His relationship with his friends might change. Some of his friends who are more used to the 'old Percy' might be a bit shocked or even worried about his new weapon choice. On the other hand, he might attract new allies who are more into modern - day combat methods. Overall, his character would have to adapt to the new implications and responsibilities that come with using a gun.
Well, perhaps in the fanfic, Percy is in a post - apocalyptic world where he has to use a gun to defend against mutated creatures. He might be reluctant at first, as he's used to more traditional weapons, but he quickly realizes the efficiency of the gun in this new, dangerous environment.
He could develop a sense of self - doubt. Maybe the process of using Chibaku Tensei makes him question if he's becoming too powerful and if he's still the same Naruto. He might worry that his friends will start to see him differently, as someone who wields such a terrifying ability. This could lead to some internal struggles within his character as he tries to balance his new power with his old self.
His sense of justice could be tested. Using a gun might seem like an easier way to defeat enemies, but Naruto has always believed in fair fights. With a gun, he'd need to reevaluate his beliefs. He could either become more of a vigilante or strive to find a balance between the power of the gun and his ninja values.
His fighting style would definitely change. He'd become more reliant on the weapon, which might make him seem more like a swordsman in addition to being a ninja. His confidence might also increase as he masters new techniques with Myrtenaster.
His character would definitely become more complex. The abuse from Gabe would shatter his innocence. He might start to see the world in a more cynical way. However, through his own strength and the support of others, he could gradually regain his hope. He could develop a sense of empathy for others who have been through similar situations. Percy would grow from a victim to a survivor, with new - found wisdom and a fierce determination to create a better life for himself.
Percy's power set would be different. Instead of just relying on his demigod powers, he would have access to Uchiha abilities. This would make him more complex in combat. He could be more strategic, using the Sharingan to analyze his opponents' moves before striking. Also, his relationships with other characters might change. Some might be afraid of his new powers, while others might try to use him for their own gain.
His character would become more versatile. With the take over magic, he would have to learn to be more strategic. Instead of just relying on his normal jutsu, he'd be thinking about which powers to take over in different situations. This would make him a more calculating and less impulsive fighter.
Her character would be different in several ways. Physically, she'd face different challenges. For example, if there are tasks that require a certain level of physical strength that were easier for male Percy, female Percy might have to find alternative ways to overcome them. Emotionally, she could be more empathetic. Since society often expects girls to be more nurturing, she might show more concern for the well - being of others. This could also change her leadership style. Instead of a more authoritative leadership, she might lead by example and through building consensus. And her sense of identity would be more complex. She'd have to balance being a girl with being a demigod, which could lead to some interesting internal conflicts.
Percy's character would be much more of a warrior. In Sparta, they were bred for war. Percy would have a different mindset. He'd be more aggressive in combat and less hesitant to use force. His sense of honor would be deeply ingrained in the Spartan way. He'd also be more used to a hierarchical society, so his interactions with others might be more formal. For example, he'd show more respect to his superiors based on their rank. His relationship with the gods would also be different. He'd have to hide his connection to Poseidon more carefully as the Spartans had their own pantheon of gods they revered, and any deviation from that could be seen as heresy.
