The main characters are usually Percy Jackson himself, as he is the central figure in the series. Annabeth Chase is also often involved, given her close relationship with Percy. Grover Underwood is another character that commonly shows up in these fanfictions, as he is Percy's best friend.
Obviously, Percy Jackson himself is likely to be one of the main characters. He's the protagonist in the Percy Jackson series, so he would be central to this fanfic too. Annabeth Chase would also probably be involved as she is Percy's close friend and often by his side in adventures. Grover, Percy's satyr friend, might also be there as he's always been part of Percy's journey.
Percy Jackson himself is often involved. His adventurous spirit makes for great truth or dare situations. Annabeth Chase is also a popular character in these fanfictions. Her intelligence can lead to some really interesting truth revelations or daring dares. Another one is Grover, who with his unique abilities and personality, can bring a lot of humor to the truth or dare scenarios.
Typically, you'll see Percy Jackson, Annabeth Chase, Jason Grace, Piper McLean, Leo Valdez, and Hazel Levesque among others. These are the main characters from the 'Heroes of Olympus' series, and in the truth or dare fanfictions, they are the ones who usually play the game and have all the interesting interactions.
The gods themselves, like Zeus, Poseidon, and Athena are also main characters. Their different personalities and powers play a big role in the fanfiction. For example, Zeus's authoritative nature might create conflicts, while Poseidon's relationship with Percy as his father adds an extra layer of complexity.
Grover could be another main character. His reactions to the crazy dares and truths would add a lot of humor and charm to the fanfiction. He might be the one to try and keep the game somewhat civilized, but fails miserably.
Annabeth is often one of the main characters in these girl talk scenarios. She's smart and has a lot of experiences to share. Another one is Piper. She has her own charm and insights, especially when it comes to matters of the heart. And of course, Hazel, with her unique background and powers, can also be part of these girl - talk sessions.
Well, I think Tyson, Percy's cyclops half - brother, would be a great addition. His simple - minded but strong nature could lead to some really funny dares and unexpected truth answers. Also, Clarisse could be included. She's tough and no - nonsense, so her participation would surely spice things up. When it comes to the game, she might give really challenging dares or be brutally honest with her truth answers. And of course, Chiron, as the wise centaur, could also join in. His age - old wisdom would make his truths very interesting and his dares would be both challenging and educational in a way.
Well, obviously Percy Jackson himself is often a main character. He's the hero of the original series, so in fanfiction related to Demeter, he usually plays a big role. Demeter is another main character, as the fanfiction is centered around her in some way. Sometimes her demigod children also make an appearance. For example, her daughter who might have some special powers related to plants or nature.
In some more creative fanfictions, new characters might be introduced. For example, a powerful demigod who was born in Tartarus and has unique abilities. These new characters can add a fresh twist to the story, interacting with Percy and the others in unexpected ways, and often bringing new plotlines related to the mysteries of Tartarus.
Percy is, of course, the main focus. However, in many of these fanfictions, Luke Castellan can also be a major character. Since Luke had his own issues with the gods and turned to the dark side in the original series, he could either be an influence on Percy's dark turn or an ally in his new dark journey. Nico di Angelo is another character who could be involved. Given his connection to the Underworld and his own complex relationship with Percy, he might try to understand what's going on with Percy or try to fight against him if he thinks Percy has gone too far.
