There are also fanfictions where his brother is an antagonist. He could be a demigod who was jealous of Percy's fame and success. This would create a lot of conflict in the story, with battles not only against monsters but also against his own brother who might team up with the enemies of Percy.
Well, sometimes in fanfiction, his brother might be a mortal who discovers his demigod heritage later. This could add an interesting twist to the story as he has to adapt to the world of gods and monsters. Or it could be a long - lost half - brother from a different camp, like a son of Poseidon from another part of the world who was hidden away for some reason.
Some minor gods related to the earth like Demeter could be allies. She has her own powers over the earth and could teach Percy some of her techniques. Also, the nymphs, such as the water nymphs and the tree nymphs, could be allies. The water nymphs could help with the water sources within the earth (like underground rivers) and the tree nymphs could help Percy take care of the forests. And let's not forget the pegasi. They could be used for transportation when Percy needs to quickly travel across his earthly domain.
Annabeth could definitely be one of his main allies. Her intelligence and strategic planning would be invaluable in a fight against Olympus. Also, Grover might be there, using his skills as a satyr to gather information and support from other nature - related beings. Some of the less - well - known demigods from Camp Half - Blood could also join in, seeing Percy as a chance for a new order.
Annabeth could definitely be one of his allies. She's smart and resourceful, and her knowledge of architecture and strategy would be useful no matter where in the universe they are. She could help Percy figure out the layout of strange alien cities or fortresses.
His friends from Camp Half - Blood would be his allies for sure. Annabeth, with her strategic mind, would be invaluable. Grover, the satyr, could help Percy communicate with nature spirits which could be useful. But also, some of the minor gods who feel left out by the major Olympians might side with Percy. For example, Hecate could use her magic to assist Percy, seeing him as a chance for a new order in the Olympian world. There's also Tyson, Percy's cyclops half - brother, who would be a strong and loyal ally.
Grover could also be an ally. His connection to nature might give Percy some unique advantages in Tartarus. Additionally, some of the less hostile creatures in Tartarus, like the friendly Cyclopes, could side with Percy. They might see him as a more just ruler compared to the chaos that usually reigns in Tartarus. Also, Chiron, with his vast knowledge and experience, could offer guidance from afar, which could be considered a form of alliance.
Perhaps there could be a team of demigods from another camp. They see Percy as a threat on the soccer field and want to prove that their camp is better. They might use their own unique powers during the game in an attempt to outplay Percy. For example, a demigod from a fire - based camp could heat up the soccer ball to make it difficult for Percy to handle.
She might be a character created to add a new twist to the story. For example, she could be a demigod with a very rare power that no one has seen before. Ariana could be a key to solving a big mystery in the fanfiction world. She could also be an antagonist at first, but then later become an ally to Percy after some character development.
He might meet some native Alaskan spirits. These spirits could be like the nature spirits he has encountered before but with their own unique Alaskan characteristics.
Well, in the 'Percy Jackson hunted by Shield' fanfiction, Percy's main source of help would be his demigod comrades. Annabeth Chase, with her brilliant mind and knowledge of architecture and strategy, could help Percy plan his escapes and defenses. Grover Underwood, being a satyr, has a connection with nature that could be used to create barriers or mislead Shield's agents. Additionally, Chiron, the centaur trainer at Camp Half - Blood, might have some ancient knowledge or magic that could be used to protect Percy or make him less detectable to Shield. There could also be other demigods with unique powers that could come to Percy's aid, for example, those with the power of invisibility or mind - control who could use their abilities to disrupt Shield's operations.
He could meet some Aboriginal heroes or spirits. They might have their own powers and knowledge that Percy can learn from.
