Well, he might have a whole different set of skills. Maybe he'd be an expert at underwater magic that's unique to Atlantis. He could have friends among the Atlantean creatures and be more in tune with the ocean's secrets there than in the regular Percy Jackson stories.
If Percy Jackson were raised in Atlantis in fanfiction, it would change a great deal. His view of the world would be shaped by the Atlantean culture. He'd probably grow up with a different set of values. For example, Atlantis might have a more hierarchical society, and Percy would have to navigate that. Also, his powers could be enhanced or different. Instead of just controlling water, he could potentially control the very essence of Atlantis, like its magical structures or ancient artifacts. He'd likely be trained in Atlantean combat styles which could be very different from what he learned on the surface. And his relationships with the gods might be more complex, as the Atlanteans may have their own take on the deities.
In fanfiction where Percy Jackson is raised in Atlantis, he would be exposed to a whole new level of underwater technology and magic. Atlantis is often depicted as a highly advanced civilization in mythology. Percy could be using advanced Atlantean weapons and tools. His connection to Poseidon might be stronger or more nuanced. Since Atlantis was said to be Poseidon's domain, Percy might be seen as a sort of prince or special figure there. He would also face different challenges. Instead of dealing with the typical Greek - monster - on - land problems, he'd be facing threats that are specific to Atlantis, like ancient curses or power struggles within the Atlantean city - states.
The 'Percy Jackson Raised by Zeus' fanfiction would be full of interesting twists. Percy's view of the world would be quite different. Instead of the usual Camp Half - Blood experience at first, he might be in a more isolated place under Zeus's watch. His skills would be honed in a different environment. Maybe he'd be taught by Zeus himself how to control the weather in extreme ways. His interactions with his friends like Annabeth and Grover would be changed too. They might initially be in awe or even a bit scared of him because of his connection to Zeus. And the overall plot could involve Percy having to prove himself not just as a son of Poseidon but also as someone worthy of Zeus's attention.
His personality would likely be a blend of his natural Percy - ness and the influence of Atlantis. He could be more inquisitive about the history and magic of Atlantis. Since it's such a mysterious place, he'd constantly be seeking knowledge. At the same time, he might be a bit more detached from the surface world, having grown up in an underwater realm. His sense of humor might also change, adapting to the Atlantean way of life which could be more formal or refined in some ways.
In this fanfiction, Percy would have a very different upbringing. Instead of growing up in a somewhat normal, if a bit chaotic, world as a demigod, he'd be in a world full of secrecy and danger. The assassin group raising him could be using him for their own purposes, perhaps thinking his demigod powers could be harnessed for their assassinations. Percy would have to struggle with his identity, being part demigod and part assassin - in - training. He might question the motives of those who raised him and eventually break away to find his own path, using both his demigod heritage and assassin skills to fight for what he believes in.
He might be a much darker and more edgy character. In a Creepypasta - influenced upbringing, he could be constantly on edge, seeing threats everywhere. His view of the mythological world might be distorted, perhaps seeing the gods as more malevolent entities.
His training would likely be intense. He'd probably learn stealth techniques like how to move silently and blend into the shadows. Swordsmanship would be a key part of it too, as he already has some skills with a sword. And he'd be trained in hand - to - hand combat, learning different fighting styles. Maybe he'd also study poisons and antidotes, just in case he ever needed to use or counter them during his assassin - like missions.
His abilities would be a unique blend. Since Percy has a connection to water, in Skyrim's environment, he could potentially use frozen water as a weapon, like creating ice spears. He might also gain an understanding of Skyrim's magic, perhaps even integrating it with his own powers. For example, he could use shouts that are related to water or the sea. And his ability to communicate with sea creatures might translate to some sort of connection with the strange creatures in Skyrim's waters.
His training would likely be intense. The Avengers could teach him combat skills like Captain America's hand - to - hand combat. Thor might show him how to handle a weapon like Mjolnir (even if he couldn't lift it fully). And Iron Man could introduce him to high - tech gadgets for battle. Also, Natasha could train him in espionage and stealth techniques.
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.
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.
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.
