There's Percy Jackson. He's a key character, being a demigod son of Poseidon. And Annabeth Chase, daughter of Athena.
The main characters include Percy Jackson, who is a very important demigod as he is the son of Poseidon. He has water - related powers and is quite brave. Then there's Annabeth Chase, the daughter of Athena. She is smart and strategic. Grover is also a main character, he is a satyr and Percy's best friend. He helps Percy a lot in his adventures. There are also other demigods who play important roles at different times in the story.
It's about a camp for demigods. Demigods are the children of gods and mortals. In this camp, they train, face challenges, and go on adventures. It has cool characters and exciting storylines.
Often, Percy Jackson is a main character. Since he's such a central figure in the Camp Half - Blood universe, in fanfictions about flash - related hurt, he might be the one directly affected by the flash, like getting zapped by some strange magic during a battle. Then he has to deal with the consequences, like weakened powers or physical pain.
Obviously, the new girl would be a main character. She could be someone with an unknown parentage at first, like many demigods. Another main character could be the camp director, who would be guiding her and trying to keep her safe. There might also be a friendly camper, like a son or daughter of Hermes, who takes the new girl under their wing and shows her around the camp.
Annabeth Chase could also be a main character. She could be using her intelligence to figure out the secrets behind a strange lemon - based phenomenon at the camp. For example, she might be trying to understand why the lemon trees are suddenly producing golden lemons with magical properties.
Typically, there's the mortal who is visiting the camp. This could be an ordinary person like a school student or a young adult just starting out in life. Then there are the demigods at Camp Half - Blood, such as Percy Jackson - like characters who are already well - known in the original series. They play a crucial role in interacting with the mortal and showing them around the camp.
I don't have enough information to determine the main characters. They could be campers, counselors, or some unique characters related to the specific type of camp in the novel.
Percy Jackson is a must - include. He's the hero of the original series and has a lot of adventures and relationships that can be further explored in fanfiction.
In Camp Half - Blood fanfiction, Nico di Angelo is a very popular character. His dark and brooding nature, along with his powers over the dead, draw a lot of readers. At Camp Jupiter, Reyna is often a central figure. She's strong, independent, and has a lot of leadership qualities, which make her a great character in fanfiction stories.
I think Tyson would be an excellent character to include. He's Percy's half - brother and his strength as a Cyclops could be very useful in various situations. His innocence and loyalty also make him a lovable character. Additionally, Clarisse could be paired with them. She has a tough exterior but deep down she's a strong and capable demigod. Her rivalry - turned - friendship with Percy could add some spice to the fanfiction. And of course, Chiron, the centaur, could be involved. His wisdom and guidance are always valuable and could play a crucial role in their adventures.
Since I haven't had the chance to read 'In the Blood', I can't say who the main characters are. However, in most graphic novels, the main characters are usually the ones driving the plot forward. They could be ordinary people who find themselves in extraordinary situations, or they could be heroes or anti - heroes with unique abilities or characteristics related to the 'in the blood' concept.
