If Percy were raised by Shinto, his character would change in multiple ways. Shinto places great importance on purification and cleanliness. Percy might develop a habit of purifying himself and his surroundings more often. This could also extend to his mental state, making him more focused and less likely to be influenced by negative emotions. His view of power would also shift. Instead of seeing power as something to be used for personal gain or to prove himself, he would see it as a tool to maintain the harmony of the world, as per Shinto beliefs. His growth as a character would involve learning to balance his Greek demigod nature with his Shinto - influenced values, which would be a complex and interesting journey.
His character would become more confident in his artistic abilities. Apollo is the god of many arts, so Percy would likely be exposed to music, poetry, and painting. He might be more flamboyant in his actions and speech, as Apollo has a certain charm. For example, he could start using more flowery language when talking to his friends or enemies.
Percy's character would likely become more in tune with nature. He'd be more reserved perhaps, as he grows up in an all - female group. His sense of honor might be more shaped by Artemis' values, such as protecting the weak and the natural world.
He would likely be more cautious and distrustful. Since he's being raised by a monster, he may not have the same sense of heroism and justice that the normal Percy has. He might see the world as a more dangerous place where only the strong survive.
His character might become more confident, as being raised by Zeus would give him a sense of specialness. He could also be more authoritative.
Percy would likely become more confident in his abilities. Apollo's influence would make him more outgoing and perhaps a bit more self - assured. He'd also probably have a greater appreciation for beauty and the finer things in life.
His character would become more bold and impulsive perhaps. Since Percy Jackson often acts on his instincts, Harry might pick up this trait. He would also be more used to teamwork in a more physical sense, as the demigods in Percy's world often fight side by side.
Percy would likely be more ruthless. Gaea's influence might make him less hesitant to use force or manipulation to get what he wants. For instance, he might not be as concerned about the well - being of mortals as he was in the original story.
His character would likely be more cynical. Growing up among monsters, he'd see the cruel side of the world early on. He might be more distrustful of others, even those who seem friendly at first. For example, when he finally meets other demigods, he'd be hesitant to trust them right away.
His powers might develop in a more self - taught way. Without the guidance of Camp Half - Blood, he'd have to figure out his water - based powers on his own. Maybe he discovers he can control water from puddles in the street to defend himself from attackers.
His personality would likely be a blend of his natural Percy - ness and the influence of Atlantis. He could be more inquisitive about the history and magic of Atlantis. Since it's such a mysterious place, he'd constantly be seeking knowledge. At the same time, he might be a bit more detached from the surface world, having grown up in an underwater realm. His sense of humor might also change, adapting to the Atlantean way of life which could be more formal or refined in some ways.
