If Percy was raised by Artemis, his personality would have a significant shift. He would be more introverted, having grown up in the company of Artemis and her hunters, who are often away from the hustle and bustle of the more populated demigod areas. He would have a strong sense of loyalty to Artemis and her cause. His sense of justice would be more intertwined with nature's balance. For example, he might be more enraged by acts of deforestation or pollution than the average demigod. He would also be more of a loner, but when he does form relationships, they would be deep and based on mutual respect for nature and the divine.
He'd likely be more reserved. Artemis values solitude and purity, so Percy might be less of a joker. He'd be more serious about his duties and tasks.
Percy's personality would be more in tune with nature. Since Artemis has a strong connection to nature, Percy would grow up respecting and understanding it more deeply. He would probably be more solitary as well, as the hunters often keep to themselves. He might not be as quick to trust others as he used to be, having been brought up in a more exclusive group. Also, he would have a greater sense of loyalty towards Artemis and the hunt, which could make him seem a bit cold to outsiders.
If Harry was raised by Poppy, his personality would be very different. Poppy is all about taking care of others and healing. Harry would have a calmer demeanor. He would be more in tune with his emotions and those of others. He wouldn't be as quick to anger or rush into dangerous situations. Instead, he'd approach problems with a more nurturing and solution - based mindset, much like Poppy does when she treats patients at Hogwarts.
Naruto's personality would likely become more stoic. Zoro is often calm and collected in the face of danger. Growing up with Zoro, Naruto would learn to control his emotions better. He might not be as quick to jump into things without thinking, as he would have been influenced by Zoro's more measured approach. Also, he might be more confident in a quieter way, not relying as much on shouting about his goals but rather showing through his actions like Zoro does.
He'd probably be more carefree. The toads have a different lifestyle compared to humans in Konoha. So Naruto might not be as eager to prove himself to the villagers right away. He'd be more in tune with nature like the toads.
Naruto's personality could be a blend of his original upbeat and determined self with Gaster's more enigmatic and calculating nature. He might be more secretive about his plans and abilities. For example, instead of shouting about his goals all the time like in the original Naruto, he would keep them to himself and work quietly towards them. He could also be more curious about the unknown and scientific aspects of things, which is something he would pick up from Gaster.
He might be more confident. The Uzumaki clan had a strong reputation, and growing up with that knowledge could give Naruto a sense of pride and assurance from the start. He wouldn't have to struggle as much with feelings of being an outcast like in the original story.
If raised by Kushina, Naruto would have a more nurturing personality. Since Kushina is a loving mother figure, Naruto would grow up seeing and learning from her kindness. He'd be less likely to seek attention through pranks as he'd already have the love and attention he needed at home. His self - esteem would be higher, and he might be more diplomatic in his interactions with others, having learned from Kushina's way of handling things.
He'd probably be more confident. Supergirl is a strong and confident character, and she'd likely instill those traits in Harry. He might not be as shy or reserved as he was in the original stories.
He'd probably be more solemn. The Shinigami is a being associated with death, so Naruto would be exposed to serious concepts early on.
His personality would likely be more disciplined. The Hokage's influence would instill a sense of order in Naruto. He'd be less likely to pull pranks just for attention.
