His other friends from Camp Half - Blood would have mixed reactions. Some would be proud of him for wanting to serve and protect in a different way. Others might think he's crazy for leaving the world of demigods and getting involved in mortal military affairs. They know he has a duty to the demigod community, and joining the military could put that in jeopardy. But overall, they would support him because they know Percy always follows his heart and they trust his judgment.
Well, his friends' reactions would be quite diverse. Annabeth might see it as an interesting new development. She could be a bit protective, making sure that Percy, as a girl, isn't taken advantage of. Grover would likely be his goofy self, but also offer his support. He might make some silly jokes at first to lighten the mood. Other friends at Camp Half - Blood would also have different reactions. Some might be curious, some might be a bit hesitant, but overall, they'd probably accept Percy in this new form because they know it's still Percy deep down, with the same brave heart.
Annabeth would probably be a mix of amused and exasperated. She might tease him a bit at first but then help him out if he's in an uncomfortable situation because of the dress. Grover would be really shocked at first but then try to be supportive. He might say something like 'Well, Percy, you look... different, but it's okay!'. As for Tyson, he would just be happy to see Percy and not really care about the dress all that much.
Well, Sasuke might initially be angry. He and Naruto have a deep bond, and Naruto leaving Konoha for another village could seem like a break in that connection. Sakura would be heartbroken. She's always cared about Naruto, and seeing him go would be difficult for her. As for the others, like Kiba and Choji, they might feel like they've lost an important part of their team. They would wonder if there was something they could have done to keep Naruto in Konoha. However, over time, they might come to accept his decision if they see that he's happy in the new village.
His friends would likely have a mix of reactions. Some, like Pikachu, would be right by his side and excited for the new adventure. Others, like his human friends, might be a bit sad at first because he'd be spending more time with the Elite Four duties. But overall, they'd be proud of him. They know how hard he's worked to get to this point in his Pokémon training journey. And they'd also be looking forward to seeing how he'd change the Elite Four with his unique style.
His friends would probably be shocked at first. They might be afraid of him because of the common perception of demons as evil. But some of his closer friends could try to find a way to help him, believing that Percy is still in there somewhere.
If Percy joins the Volturi in fanfiction, his personality could change in multiple ways. At first, he might be very resistant to their ways. But as time passes, he could become more like them in some aspects. He would be surrounded by vampires who are mainly concerned with power and control. This could make him more power - hungry. But also, Percy has a strong sense of justice. So, he might try to use the Volturi's power structure to enforce his own sense of right and wrong. This could lead to him being more authoritarian in his approach. He might also become more isolated as he can't fully trust the other Volturi members, which could make him more withdrawn and less likely to show his true emotions.
His character could become more in tune with nature. The Hunt has a strong connection to nature, and Percy would likely pick up on that. He might also become more self - reliant as the Hunt often operates independently. His loyalty would be tested as he has to balance his old ties with Camp Half - Blood and his new life in the Hunt.
He might become more aloof. Since Chaos is such a vast and unpredictable concept, Percy may start to distance himself from his old, more emotional self. He could become more calculating as he has to deal with the new and often dangerous situations in the chaos realm.
His relationship with Annabeth would become more complicated. Long - distance and the difference between the two camps could put a strain on their relationship. Among the Romans, he might develop a close friendship with some of the more battle - hungry demigods who admire his skills. He could also have a rocky start with the Roman leaders who may be cautious about his motives.
Percy's view of the mortal world would expand. Being in the army, he'd see a different side of mortals - their teamwork, their sense of duty. He might also learn new skills like military strategy that could enhance his demigod fighting abilities. His loyalty might be tested as he has to balance his loyalty to his demigod friends and his new military comrades. And his sense of self - worth could change as he discovers new ways to contribute in a military setting.
