Sally Jackson, Percy's mother, is also an important character. Her love for Percy and her strength can be a central part of the story. She could be the one who gives Percy the emotional support he needs when he's confused or scared about the strange things happening around him. In a fanfiction, she could also have some secrets of her own related to the mythological world that Percy discovers as he grows up.
Luke could be an interesting addition. Even as a kid, he could be shown as having a bit of an edge, someone who Percy looks up to but who also has some underlying motives that are not so clear at first. This can add an element of mystery and foreshadowing to the fanfiction. For example, Luke could be the one who tells Percy about some of the more dangerous aspects of the mythological world in a way that seems exciting but also a bit off - putting.
Well, obviously Percy and Phoebe are the main ones. But other great characters to include could be Annabeth. She could be jealous of Phoebe at first, creating some interesting drama. Grover would also be a good addition. His ability to sense danger and his friendship with Percy could play an important role in the story.
Well, obviously her father Percy Jackson should be included. His experience and wisdom could be a great help to his daughter. Annabeth Chase could also be a great addition. She could be like a mentor to the daughter, teaching her things about strategy and knowledge.
Definitely Chaos. As the origin of all things, it would add a whole new level of mystery and power to the story. Also, Nyx, the goddess of the night, could be really interesting. Her dark and powerful nature would contrast well with Percy's more heroic and light - hearted side.
Percy himself is obviously a must - include. His journey of leveling up is the core of the story. Annabeth is also great as she can be a support and also have her own leveling - up arc related to her wisdom and battle strategies. Grover could be there too, as he often provides comic relief but can also level up his own nature - related powers.
Leo Valdez would also be an excellent character to include. His mechanical skills and sense of humor could lighten the mood during tense situations. He could also create some cool gadgets to help the group in their adventures, like a device to detect mythical energy or something similar.
Paul Blofis should be in it. Since he's Sally's husband, his presence would add an interesting layer to the family dynamic in the fanfic. He could be involved in some humorous situations when it comes to understanding Percy's demigod world.
Definitely Percy himself. He is the main character of the original series, and his actions and decisions drive the story forward. Annabeth is also a great choice. Her intelligence and strategic thinking often complement Percy's more impulsive nature. Grover can bring some humor to the story with his satyr antics.
Definitely Annabeth from the Percy Jackson series. She can bring her strategic mind and knowledge of Greek mythology to the mix. And for the Magnus Chase side, Samirah. She has her own set of skills and beliefs from the Norse side that can add a lot of depth.
Annabeth is a great choice. Her intelligence and strategic thinking could add a lot to the story. For example, when Percy and Grover are in a tight spot, she could come up with a clever plan to get them out. Another good character is Tyson. His strength and loyalty would be useful in battles and dangerous situations.
Jason is another good choice. He has a history with both Percy and Reyna. His leadership skills and his connection to the Roman side of the demigod world could bring in new plotlines. For example, he could help Percy and Reyna understand some of the more complex Roman demigod politics that they need to navigate.
