In addition to Percy and Annabeth, there could be the kids they are babysitting. These kids could be new characters created for the fanfic, or perhaps they could be the children of other known demigods. There's also a chance that some minor gods or goddesses could show up, either to cause trouble or to help out. For instance, Hermes could pop in to play a little trick on Percy and Annabeth, or Aphrodite could come to give some relationship advice to the two.
Obviously, Percy and Annabeth are the main characters. But we could also see some of their demigod friends like Grover. Grover might stop by to check on them and end up getting involved in the babysitting chaos. Maybe Chiron could also make an appearance, giving Percy and Annabeth some advice on how to handle the kids.
In this fanfic, Percy and Annabeth could face some challenges. For example, the babysitting job might be a part of a quest. The kids could be in danger from some mythical creatures. Percy and Annabeth would then have to protect them while also taking care of their basic needs. They might also teach the kids about Greek mythology and their own powers, which could be really interesting.
Obviously Percy himself. Also, Annabeth would probably be there as his girlfriend. Grover, his satyr friend, might also make an appearance. And the gods, like Poseidon, Percy's father, would surely play a role, either guiding Percy or testing him on his path to godhood.
Obviously, Percy himself would be the main character. Annabeth would most likely be there too, as she is an important part of Percy's life. Grover would also be a likely character, being Percy's best friend.
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.
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.
The main characters are most likely Annabeth and Percy. Since Annabeth is the one who is pregnant, she would be a central figure. And Percy, being her partner, would play a crucial role in protecting her and the unborn child in Tartarus.
