In a baby - Percy fanfiction, his character development would likely be more influenced by the adults around him. His mother would play an even more crucial role in shaping his values. She might tell him stories of the gods that are more like fairytales at first, which later turn out to be real. And as he starts to interact with other demigods his age, he would have to unlearn some of the more 'childish' understandings he had, leading to a more complex character growth.
As a baby, Percy's character development would start from a very innocent and instinct - driven state. Instead of the typical teenage bravado, his early development could focus on his natural abilities emerging in a more uncontrolled way. For example, he might accidentally zap things with his water powers when he's excited or scared.
His character could be developed differently in that his relationships would be formed at a much earlier age. Maybe he forms a strong bond with a particular satyr who finds him as a baby. This satyr becomes like a big brother to him, teaching him about the demigod world in a more child - friendly way. And as he grows, this relationship shapes his view of the world and his place in it.
In these fanfictions, Percy's character is often more edgy. He has to be more calculating and less impulsive compared to his original self. Since he's dealing with the assassin - like role, he can't just rush into things. For example, he might take more time to plan his attacks against enemies.
Their relationship could be developed by having Percy's father teach him new and advanced powers related to the sea. This would create a more mentor - student dynamic.
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.
Canon Percy is a son of Poseidon. If he were the son of Artemis and Orion, his character would be more reserved in terms of relationships. Since Artemis is associated with chastity, Percy might be more cautious about romantic involvements. Also, his combat style would be different. Instead of relying on water powers, he'd focus more on archery and hunting skills.
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 could start to form new relationships within the Faunus community. These relationships could teach him different values and ways of life. Maybe he'd meet a Faunus mentor who would help him understand and control his new Faunus powers, if he has them. This would be a big part of his development, as he'd be learning from a completely different perspective than he's used to at Camp Half - Blood.
Well, in some fanfictions where Naruto is a fox, his character can be more in tune with his animal instincts. He might be more cunning and quick - thinking, using his fox - like abilities to his advantage in battles. For example, he could use his enhanced senses to detect hidden enemies or traps more easily.
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.
