If Percy was born a Roman in fanfiction, his allies would change a great deal. He'd be part of the Roman demigod community, so he'd be friends with those who follow the Roman way. For instance, Frank Zhang could be a closer ally. Frank has his own unique powers and a strong sense of loyalty to the Roman camp. Percy would also have to deal with different internal politics within the Roman camp as an ally. Regarding enemies, the Titans and Giants might view him as a more significant threat. Since the Romans were seen as a powerful military force in the mythology world, they might target Percy more aggressively to try and disrupt the Roman order and power structure.
In a 'Percy Jackson Born a Roman' fanfiction, when it comes to allies, Percy would find himself among the Roman demigods. His relationships with them would be based on Roman values such as honor and duty. For example, Hazel Levesque could be a key ally. She has her own connection to the Underworld which could be useful in their adventures together. And in terms of enemies, the nature of his opposition would shift. The Roman view of monsters was often more about military conquest. So, some monsters that were perhaps more of a nuisance in the Greek - centered stories could be full - blown enemies in the Roman context. Also, other groups like the Amazons or certain tribes of centaurs might have different relationships with him as a Roman compared to if he were a Greek demigod.
Well, if Percy Jackson was born a Roman in fanfiction, his whole upbringing would be different. He'd be trained in the Roman way of fighting and thinking. Maybe he'd be more disciplined from the start, as the Roman camp is big on that. He'd also have different relationships with the gods. Instead of the more laid - back Greek god interactions, he'd have to deal with the more formal Roman ones.
If Percy Jackson was born a Roman in fanfiction, a lot would change. For one, his training and upbringing would be different. He'd be in the Roman camp from the start, so he'd be trained in the Roman style of combat and leadership. His relationships would also be different. Instead of his close bond with Annabeth from Camp Half - Blood, he'd form different friendships within the Roman camp. Maybe he'd be closer to Hazel or Frank. His view of the gods might also be more in line with the Roman view, which is more about duty and honor to the state as well as the gods.
His relationship with Annabeth would be really different. In the Roman context, they might be more like rivals at first. The Greeks and Romans have their own ways, and Annabeth, being Greek - minded, would clash with Percy if he was Roman - born. But later, they could learn from each other.
His mother, Sally, would surely be one of his allies. She has always been there for him. Also, Grover could be his ally as they have a long - standing friendship. Grover might see Percy as an even greater protector of the nature spirits now that he's a god.
She would likely be more influenced by Roman values. While Percy is impulsive and often acts on his gut feelings, she might be more disciplined, following the Roman way of strict military - like order. For example, in battle, Percy might charge in headfirst, while she would plan out her moves carefully, taking into account the formations and strategies taught in the Roman camp.
His powers could be more nature - based. For example, instead of just controlling water, he might be able to control all forms of liquid in nature, like sap or blood. His connection to the wild could also make him more attuned to the emotions of animals, allowing him to communicate with them more effectively.
Well, in a fanfiction where Percy is born in Greece, his powers would likely have a more 'Greek - flavoured' aspect. Since he's in the homeland of the Greek gods, his connection to water could be intertwined with the Greek concept of the four elements. So, his water powers might interact more with the other elements in a way that is more in line with Greek elemental theory. He might also be able to draw on the power of Greek water deities more directly, which could enhance his abilities and give him new ways to use his powers in battles and other situations.
His relationship with Annabeth would be very different. Instead of their usual dynamic on land, they'd have to figure out how to interact in the water. Annabeth might have to learn to trust Percy in his new form, and Percy would have to deal with any insecurities about his merman self. Their relationship could become more strained as they adjust, or it could grow stronger as they face new challenges together.
Percy's character would be much more of a warrior. In Sparta, they were bred for war. Percy would have a different mindset. He'd be more aggressive in combat and less hesitant to use force. His sense of honor would be deeply ingrained in the Spartan way. He'd also be more used to a hierarchical society, so his interactions with others might be more formal. For example, he'd show more respect to his superiors based on their rank. His relationship with the gods would also be different. He'd have to hide his connection to Poseidon more carefully as the Spartans had their own pantheon of gods they revered, and any deviation from that could be seen as heresy.
His powers could also be more regulated. The Roman military has a strict code of conduct, so Percy may not be able to use his powers as freely as he did as a Greek demigod. He might have to get permission from his superiors before using his powers in combat or for other tasks. This could lead to some interesting situations where he has to hold back or find alternative ways to solve problems.
