Percy could develop a more primal side. The monster's influence might make him more in tune with his instincts. For example, he could be better at hunting or sensing danger. However, he may also struggle with his humanity, constantly having to balance the monster - like traits he's picked up with his own human values.
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.
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 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. Since he's born with this connection to monsters, he might be more aware of the dangers around him from a young age. He'd be less likely to rush into things like the normal Percy does. For instance, when he first hears about Camp Half - Blood, instead of just going along with Grover, he might be more hesitant and ask a lot more questions because he knows the potential threats monsters pose.
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.
Percy would likely be more in tune with the concept of home and family. Since Hestia represents the hearth, Percy might be more nurturing and protective. He could develop a stronger sense of responsibility for the well - being of his friends as if they were his family.
Percy would likely be more brooding. Since Iapetus was often seen as a rather serious figure in mythology, Percy might inherit some of that solemnity. He could be more withdrawn, thinking deeply about his new identity.
Percy would likely become more devious. Growing up with Loki as an adoptive father, he'd be exposed to Loki's tricks and lies. So instead of his straightforward, if sometimes impulsive, nature in the original Percy Jackson stories, he might think more about the different angles of a situation before acting.
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.
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.
