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.
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.
Naruto's character could change in several ways. Firstly, he might become more secretive as he tries to figure out what the gun is without causing panic. He's always been an open book, but this strange discovery might make him hold back some information. Secondly, he could become a bit more of a loner as he delves into understanding the gun on his own. He might feel that his friends won't understand this new aspect of his world. Also, his sense of right and wrong could be challenged. The gun's lethality is different from his normal weapons, and he'd have to decide how and when it's appropriate to use it, if at all, which would be a big shift in his character.
Naruto might become more cautious. Guns are very different from ninja tools, and one wrong move could be fatal. So he'd have to think twice before acting impulsively, which is a big change from his usual head - first approach.
Well, if Harry Potter used a gun, it could potentially make the story more dangerous in a different way. Guns can be very lethal and quick, unlike some spells which can be deflected or countered with magic. This would change the pacing of the story. Instead of long, drawn - out magical battles, there could be sudden and decisive shootings. However, it would also be a bit out of place in the magical world of Hogwarts. The charm and allure of the school with its secret passages and magical creatures would be somewhat marred by the presence of a Muggle weapon like a gun. It would be like introducing a modern - day object into a medieval - like magical setting.
He'd probably be more aware of his appearance. Instead of just being a scruffy, normal - looking demigod, he might take more care in how he presents himself. He could also be more charming without really trying, which might get him into trouble sometimes as people might misinterpret his intentions.
It might make her seem more resourceful. Instead of relying solely on magic, she's now using a muggle weapon. This shows that she's open to different ways of solving problems.
Percy would probably become more in tune with emotions. He would be able to sense the feelings of those around him more acutely. This could make him more empathetic but also more vulnerable. His relationships would change significantly. For example, his relationship with his mother, Sally, might take on a new dimension as he discovers more about his divine heritage related to love. And his relationship with Annabeth would be tested as he has to balance his newfound charm and emotional awareness with their existing bond.
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 likely become more hardened. The military life is tough and Percy would have to face a lot of difficult situations. He might become less trusting at first as he'd be in a new environment full of strangers. But over time, he could learn to rely on his new comrades. Also, his sense of responsibility would expand from just protecting his friends and family to protecting his entire unit and his country in the context of the fanfiction.
Percy could become more self - reliant. In Tartarus, he can't always count on his friends or his powers in the same way as on the surface. So he'll have to dig deep within himself to find new strengths. He may also become more strategic in his thinking, as one wrong move in Tartarus could mean death.
