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.
In fanfiction, if Percy Jackson was raised on the streets, he might be a lot more street - smart. He'd probably have to fend for himself from a young age, learning how to steal food or find shelter. His skills with a weapon might be more rough - and - tumble, developed from having to fight off bullies or thugs on the streets.
Well, one possible plot could be Percy having lost his memory. He's living on the streets, trying to figure out who he is. Maybe he has these strange dreams about a sword and a camp, but he can't quite make sense of them. As he survives on the streets, he starts to discover he has some strange abilities, like being able to control water from the puddles during rainstorms.
Percy copes by holding onto his hope. He knows that his life on the streets is just a temporary situation. He spends his days looking for clues about how to get back to his normal life. He also tries to stay positive by remembering the good times he had at Camp Half - Blood. He tells stories of his adventures to the other homeless people, which not only helps him but also gives them some entertainment and hope.
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.
The plot could be centered around Percy's identity crisis. Since he's raised by Apollo, he might struggle with whether he should follow Apollo's more flamboyant and carefree ways or stay true to his own nature. He could be exposed to Apollo's many lovers and children, which would make him question his place in this complex family. Additionally, his relationship with other demigods would change. He might be seen as an outcast by some who are loyal to Poseidon, while others might be jealous of his connection to Apollo. This would lead to various adventures where he has to prove himself not just as a son of Poseidon but as someone with a unique upbringing under Apollo.
If Percy Jackson was raised in the Underworld, his personality would likely be much darker. The environment of the Underworld is gloomy and full of death. He could be more brooding and less trusting. His fighting style might also change, incorporating more of the Underworld's magic and powers. He may even have a different weapon, something more associated with the Underworld like a bone - made sword or a whip made from the shadows of the dead.
One possible plot could be that Percy, being raised by Artemis, grows up with a deep connection to nature and the moon. He might be trained in archery and hunting from a young age. Since Artemis is a virgin goddess, Percy would have to deal with the unique situation of being part of her all - female group, perhaps facing some initial resistance from the hunters. He could also develop special powers related to the moon or gain an enhanced sense of stealth.
One possible plot could be that Percy discovers he has a special connection with dragons. Maybe he finds out that the dragons sense his demigod powers and take him in as one of their own. He then learns dragon - related skills like flying on their backs or using dragon fire in battles against his usual foes in the Percy Jackson universe.
