Definitely Sally Jackson. In the original Percy Jackson series, she's shown as a very strong single mother. Fanfiction writers could explore more of her past, like how she dealt with being a single mother before Percy even knew he was a demigod. Percy himself could also be a likely candidate in some fanfiction. Imagine if something happened to Annabeth and he was left to raise their child alone. He'd have to rely on all his demigod skills and the lessons he learned from his own mother. Then there's Chiron. He could be a single father - figure in a sense. Maybe he takes in a young demigod whose parents are lost and has to raise them as his own, which would be an interesting take in fanfiction.
Sally Jackson is a very likely character. She has already been through a lot as a single mother in the original story, so it's easy to imagine more in - depth fanfiction about her single - parent experiences. Another one could be Poseidon. Although he's a god, in some alternate fanfiction scenarios, he could be a single father to Percy, perhaps exploring what it would be like if he had to be more involved in Percy's upbringing on a daily basis. And of course, Annabeth. Given her strong - willed and intelligent nature, she could be a single mother in fanfiction, facing the challenges of raising a demigod child on her own.
One interesting storyline could be a single parent Percy Jackson trying to balance his demigod duties with raising his own demigod child. He'd have to deal with monsters while also making sure his kid gets to school on time. Another could be a single - parent character from the Percy Jackson world, like Sally Jackson, dealing with the loss of Percy in some alternate universe and how she copes with it. There could also be a story about a new single - parent demigod who shows up at Camp Half - Blood and has to adjust to the camp life while also taking care of their child.
Draco Malfoy would be a likely character. Given his Slytherin status, he would likely have a complex relationship with Percy. He might start off as hostile, seeing Percy as an outsider, but then they could end up having to work together for some reason.
One character that could betray Percy is Thalia. She has her own issues with the gods and her place in the world. Maybe she gets jealous of Percy's growing popularity and power among the demigods. So, she decides to side with an enemy to take Percy down a notch. Additionally, some minor characters that Percy has helped in the past could be the ones to betray him. They might feel indebted to him but also resentful at the same time. An enemy could manipulate their feelings and turn them into traitors against Percy.
Ares could be a likely character. He's always been somewhat of a wild card in the Percy Jackson series. He might betray Percy for his own amusement or to gain more influence in Olympus. Another could be Zeus. He's often paranoid about his power and might see Percy as a threat and betray him to protect his throne.
His mother, Sally Jackson, could play an important role as an ally. She has a strong will and has always been there for Percy. Also, Tyson, his cyclops half - brother, could be a powerful ally with his strength and loyalty. And don't forget about the Nymphs. Some of the water nymphs might help Percy since he has a connection to water.
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.
Well, Clarisse might be paired with a more aggressive Doom character. She's a fierce warrior in the Percy Jackson series. They could form a powerful duo, fighting side by side against the common enemies. Also, Tyson could be paired with a strong, hulking character from Doom. Tyson is a Cyclops with great strength, and finding a counterpart in Doom that shares that physical power would create an interesting dynamic in the fanfiction.
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.
Well, Percy is a given. He's the hero of the series. His journey after the war, whether it's about finding peace or facing new challenges, would be a major focus. Then there's Annabeth. She's not only Percy's love interest but also a strong and intelligent demigod. Her role in rebuilding and strategizing post - war would be important. Another character who might be in focus is Thalia. She has a leadership quality and a connection to the Hunters of Artemis. After the war, she could be involved in protecting the demigod world in a different way. And Jason, if he's alive, his experiences in different camps and his relationship with Piper could also be explored in the context of post - war changes.
