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.
His character might become more confident, as being raised by Zeus would give him a sense of specialness. He could also be more authoritative.
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.
Her power development could be different in that she might be more attuned to the hidden and mysterious parts of the sea. Percy is great at using the sea for obvious things like creating waves for attacks or traveling. But she could be able to unlock secrets of the deep sea, like finding lost treasures or ancient magic that has been dormant for ages. She might also have a different way of controlling water currents. Instead of Percy's more brute - force approach, she could be more delicate and precise, like using water currents to weave a protective barrier or to guide small sea - creatures to safety. This would set her apart from Percy and give her a unique power set in the fanfic world.
