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.
Percy is the main character returning from Tartarus, so he's a given. Annabeth would be there as she's his love interest and has always been by his side. Chiron, the centaur mentor at Camp Half - Blood, would probably play a role in helping Percy adjust back. Also, Nico di Angelo might be involved since he has his own connections to the underworld and could understand Percy's experiences to some extent.
Well, Percy is the star of the fanfiction. Then there's Annabeth, who will be worried sick about him. Tyson, Percy's cyclops half - brother, could be there to welcome him back and offer his unique brand of support. And the gods might be keeping an eye on Percy too, especially Poseidon since he's Percy's father. They would be curious about what Percy has become after his time in Tartarus.
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.
Obviously, Percy would be the main character. He's the one stuck in Tartarus, so the story would revolve around him. Maybe Annabeth could also be an important character, even if she's not physically in Tartarus with him. Her thoughts and attempts to rescue Percy from afar could be part of the story.
Obviously, Percy would be the main character. Since he is the one sent to Tartarus. Annabeth might also play an important role, even if she's not in Tartarus with him at first. She could be on the surface world trying to figure out a way to get to him or send help. Grover could be another likely character. His connection to nature might come in handy in some way, like if there are strange nature - based elements in Tartarus that only he can understand or control.
The main character is Percy, no doubt. However, in this type of fanfiction, we could also expect to see characters like Thalia Grace. She has her own connection to Percy and could offer a different perspective on his situation. The centaur Chiron might also be a main character as he is often a guiding figure for the demigods. And there could be new characters introduced, perhaps other dark - themed characters who are either drawn to Percy or are trying to oppose him because of his changed state.
Annabeth could be one of the characters. She might come to Tartarus to rescue Percy or be accidentally dragged in while trying to find him. Grover could also show up, using his nature - related powers to navigate the strange and dark environment of Tartarus. Another potential character could be Nico. Given his connection to the Underworld, he may be able to sense Percy's presence in Tartarus and come to his aid.
Well, it could involve Percy coming back with new powers. Maybe he's more in tune with the underworld's magic. He might have made some sort of deal in Tartarus and now has to deal with the consequences in the mortal world.
Some of the more powerful and vengeful spirits in Tartarus could be the main antagonists. These spirits could possess demigods or mortals close to Percy to get to him. They might be angry that he escaped their domain and want to drag him back. Additionally, there could be a group of rogue demigods who believe that Percy has been corrupted by Tartarus and they see it as their duty to stop him, even if it means becoming his enemies.
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.
Annabeth would be a likely character to appear. Since she and Percy are so close, she might try to find a way to rescue him from Tartarus. Another character could be Nico. He has experience with the Underworld and might be able to offer some help or advice. Grover could also show up, using his nature - related powers to try and sense Percy in Tartarus.
Obviously, Bardock himself. And of course, Goku would likely be in it since he's Bardock's son. Vegeta might also show up, as he is an important Saiyan character. There could also be other Saiyans like Nappa or Raditz, especially if the story is about Bardock trying to reform or reunite the Saiyan race.
