Who are the main characters in 'Percy Jackson Immortal Son of Hades Fanfiction'?

The main characters are Percy and Fem Hades. Percy is the protagonist from the original series, and in the fanfiction, his story continues with his interactions with Fem Hades. Fem Hades, on the other hand, is a unique take on the Hades character. She could have different personality traits compared to the male Hades in the original mythology. There might be other characters that are introduced as the story progresses, but these two are the foundation of most Percy Jackson and Fem Hades fanfiction.

Annabeth Chase might also be an ally. Her intelligence and strategic thinking could be valuable assets for the son of Hades. She could help him plan his moves, especially when dealing with the complex politics among the demigods and gods.

One interesting plot could be Percy having to navigate the Underworld politics due to his relation to Hades. Maybe he has to deal with rivalries among the different factions down there while also trying to keep his identity a secret from some of the more dangerous entities. Another plot might involve him using his unique powers, a combination of Poseidon and Hades' abilities, to defeat a new and powerful monster that is threatening both the mortal and the underworld realms.

The main antagonist could also be an ancient and powerful spirit from the underworld that was sealed away long ago. Percy's presence as the son of Hades accidentally awakens this spirit. The spirit then starts to spread darkness and despair throughout the world of the demigods, and Percy has to find a way to stop it before it's too late.

Another option could be some rogue demigods who are jealous of the son of Hades' powers. They might form a group and try to cause trouble for him and Percy Jackson. They could be working with some minor gods who have a grudge against Hades, creating a complex web of enemies.

One idea could be Percy having to mediate between Zeus and Hades during a major feud. Since he's the son of both in this fanfiction, he has a unique connection to them. He could use his powers and his knowledge of both of their domains to try and broker peace.

Percy Jackson is definitely a main character. He's the one at the center of the 'son of chaos' concept. Then there are his friends from Camp Half - Blood like Annabeth. She might be involved in trying to understand Percy's new situation or helping him in his new adventures. Grover could also be there, being Percy's loyal friend as always.

The main characters would be Percy Jackson, who has to deal with the implications of being the son of Cerberus. Then there's Cerberus, whose relationship with Percy is the central concept. Chiron, the centaur at Camp Half - Blood, would also be important as he's always been a guide for Percy. And don't forget about the other demigods at the camp. They would react to Percy's new identity in different ways, some with suspicion, some with curiosity, and their reactions would be part of the story.

Annabeth Chase would probably also be an important character. She has always been Percy's close friend and in this fanfiction, she might play a role in helping Percy understand and control his new powers related to the void. She could be the voice of reason when Percy is tempted by the darker aspects of his new identity.

Obviously, Percy Jackson is the main character. But there could also be Annabeth Chase, his long - time friend and love interest. Grover, his satyr friend, might also play an important role. And since it's related to the Fates, the three Fates themselves - Clotho, Lachesis, and Atropos - could make appearances, either as allies or antagonists depending on the story.
