The characters would have to adapt to the different time period. For example, Percy would probably have to wear the clothing of the 1700s, which would be quite different from his modern attire. His way of speaking might also change slightly to fit in better.
In a 1700 - set Percy Jackson fanfic, the characters would be influenced by the social norms of that time. Female characters, for instance, might have less freedom compared to modern - day. They could still be powerful demigods, but they'd have to navigate the more restrictive gender roles of the 1700s. And the villains would also be shaped by the values and power structures of that era. They might be more concerned with things like colonial power or the control of trade routes, which could be tied to their evil plans.
Annabeth would be devastated. She and Percy have a deep connection. She might go into a state of shock at first, then be filled with a fierce determination to find out who was responsible and make them pay. She would probably also be racked with guilt, thinking she could have done something to prevent it.
Their worlds could collide when a mythological creature shows up in a Shield - protected area. This would force Shield agents to deal with something beyond their normal scope, and Percy would be called in to handle it because of his knowledge of the mythological world.
The characters in Percy Jackson dark fanfic can be much more morally gray. For example, Annabeth could be more ruthless in achieving her goals. Percy might be more jaded and less idealistic, having seen too much of the dark side of the demigod world. Grover could also be a darker character, perhaps being more tempted by the power of the wild in a negative way.
Grover would be panicked. He's Percy's friend and he cares a great deal about him. He might start running around trying to find help, like looking for a healer or someone with magical healing abilities. He'd probably be muttering to himself about how he should have protected Percy better.
Their powers might also combine in more complex ways. Harry's Patronus, which is a manifestation of positive energy, could interact with Percy's ability to sense and manipulate emotions related to the sea. When they are in a tough situation near a large body of water, Harry's Patronus could give Percy the extra boost of positive energy he needs to control the sea in a more powerful way, like creating huge tidal waves against their foes.
Percy's water - bending abilities are not just about combat. He can also use them to communicate with sea creatures, which could provide valuable information. His humorous and somewhat rebellious nature would add a light - hearted touch to the group. Orion, on the other hand, is very serious about his hunting. His power in archery and tracking is top - notch. His rather aloof personality might seem cold at first, but as the story progresses, he could warm up to Percy and Theseus. Theseus, as a strong and brave hero, is used to being in charge. His ability to fight hand - to - hand is crucial. In group situations, Percy's powers could be used for distractions, Orion's for long - range attacks, and Theseus' for close - quarters combat. And personality - wise, they would have to learn to adjust to each other's quirks in order to function as a team.
Annabeth would be completely devastated. She would probably go into a state of shock at first, then be filled with anger and determination to find a way to bring him back, if possible. She might even go on a solo quest to try and reverse his sacrifice.
Percy would likely develop a deeper sense of compassion and understanding. He's used to dealing with powerful beings, but a disabled Artemis would show him a different side of the gods. Artemis, on the other hand, would have to learn to rely on others, which is a big change for her. She might become more humble and see the value in teamwork. For example, Percy could teach her some of his survival skills, and she could in turn share her knowledge of the hunt.
The Voltron characters, being used to a more high - tech and space - faring environment, would be initially shocked by the magic in the Percy Jackson world. Keith might be a bit standoffish at first, but Percy's leadership skills could earn his respect. Lance would probably be fascinated by all the different mythological creatures and would try to flirt with some of the female demigods. Hunk would bond with the demigods over food, as there could be some interesting magical foods in the Percy Jackson world that he would love to try.
They could interact in a way where Percy challenges Persephone's traditional views. For example, Persephone might be used to the strict rules of the Underworld and her role as Hades' wife. Percy, with his more modern and free - thinking ways, could make her question some of those things. This could lead to some interesting conversations and a shift in their relationship.
