Obviously Percy himself. And likely his friends like Annabeth. She would probably play a role in either helping him adjust or trying to find a way to reverse the situation if Percy doesn't want to be a god.
The gods would be prominent characters. Zeus might be involved, either as the one forcing Percy into godhood or as an obstacle in Percy's path. Poseidon, being Percy's father, would also likely be part of the story. He could be trying to protect Percy or having his own plans regarding Percy's new status. Other minor gods might also show up, either to support or oppose Percy.
There could be new characters created specifically for this fanfiction. Maybe some sort of mentor figure who has been through a similar situation in the past and can guide Percy. Or an antagonist who wants to use Percy's new godhood for their own evil purposes, like a rogue demigod who wants to steal Percy's powers.
There could be other demigods as well. Nico, for example, might play a role. Given his own experiences with the underworld and his complex relationship with Percy, he could offer different perspectives. Thalia, with her strength and leadership, could also be involved. She might be a bit skeptical of Percy's new role at first but would eventually come around to support him. And of course, the gods themselves could be supporting characters in different ways, some helping Percy adjust, others causing trouble for him.
Obviously, Percy Jackson himself would be the main character. Khione, as the one who bestows the blessing, would also be there. Annabeth Chase might be in it too. She could be either helping Percy understand his new powers or being a bit skeptical about the whole blessing thing. Grover could also show up, perhaps being a bit scared of Percy's new ice - related abilities at first but then getting used to them.
Obviously Percy himself. Annabeth would likely be there as she has a close relationship with Percy. Grover might also show up, being Percy's long - time friend. And some of the other demigods from Camp Half - Blood, like Jason or Piper, could be in the story too.
Obviously, Percy himself is the central character. Annabeth would likely be there too, as she's an important part of Percy's story in the original series. Grover, his satyr friend, could also make an appearance. And of course, there might be appearances from some of the gods or goddesses, like Poseidon since he's Percy's father. Maybe even some new demigod characters created specifically for the fanfiction.
Well, there could be new characters created specifically for this fanfiction. For instance, Chaos might have his own loyal servants or minions who interact with Percy. There could also be other heroes or demigods from different pantheons. They might come to Percy for help or to challenge him. And of course, Percy's mother, Sally. She might be worried about her son and try to reach out to him, even though he is now in the realm of Chaos. Her presence could add an emotional aspect to the story as Percy has to balance his new life with his love for his mother.
The Hunters of Artemis are very likely to show up. They are Artemis's loyal followers and would surely be involved in the search for their mistress. Annabeth could also be there. She's Percy's friend and has great wisdom, which could be useful in devising a plan to save Artemis. Grover might be another character. His ability to sense things could help in tracking Artemis or finding clues about her whereabouts.
Percy is the main character so he'll be there. Annabeth will probably be by his side as she often is in his adventures. Leo Valdez could also be a character in this fanfiction. His mechanical skills might come in handy if there are any traps or devices related to the Host of Apophis. Piper McLean could be involved too, using her charm - speak to influence certain situations. And Thalia Grace, the daughter of Zeus, could make an appearance. Her leadership skills and her ability to call lightning could be important in the fight against the Host of Apophis.
Obviously, Percy Jackson himself. Then there would probably be Annabeth, his girlfriend. She could be either supporting him in his new role or be a bit skeptical at first. Grover might also show up, providing some comical relief and maybe some sage advice from his nature - centric perspective. Other gods like Aphrodite would surely be there, either causing trouble or trying to manipulate Percy for her own purposes.
Percy, for sure. He's the center of the Percy Jackson world. Then there's Tyson, Percy's cyclops half - brother. He could be working in the kitchen of the coffee shop, making giant - sized coffee treats. Clarisse might show up, causing a bit of a ruckus as she demands her coffee strong and fast. And Chiron could make an appearance in human form, sitting at a table and giving Percy some sage advice over a cup of cappuccino. The gods could also make cameo appearances. For example, Dionysus might visit the coffee shop to complain about the quality of the coffee, thinking it should be more like his wine.
Well, Percy himself is of course the main character. Annabeth would also be very likely to be there. Their relationship is a big part of the Percy Jackson series, and in a Tartarus - related fanfiction, she could be either with Percy from the start or trying to find a way to rescue him. Grover might also show up. His loyalty to Percy and his skills as a satyr could be useful in the dangerous environment of Tartarus.
