Well, the two main characters are Percy and Zoe. Percy, the son of Poseidon in the Percy Jackson universe, is known for his courage and loyalty. Zoe, who has been disowned by Poseidon, is now in a difficult situation. Their interactions, with Percy being the savior and Zoe the one being saved, will drive the plot of this fanfiction.
In this fanfiction, the plot could start with Zoe being cast out by Poseidon. Percy, being the hero he is, steps in. He first has to find Zoe as she might be in hiding or on the run. Then, he would have to fight off any pursuers. Along the way, they might develop a deeper bond as Percy helps Zoe come to terms with her new situation. Maybe they even team up to prove to Poseidon that Zoe is worthy.
Percy, of course, is central to the story as he is the savior. He has his history of heroic deeds and his relationship with other characters in the original series which might play a part in this fanfiction. Zoe is the damsel in distress here, and her backstory could be explored further in the fanfiction. Atlas, as the big bad, is there to create the tension and the need for Percy to act. He is a powerful and ancient figure, which adds to the stakes of the situation.
If Percy saves Zoe, it would likely have a significant impact. Maybe it unlocks hidden powers for Percy or makes Zoe more dependent on him. There are so many possibilities for how this could unfold.
Well, clearly Percy and Poseidon are the main characters. Percy, as a baby, is full of potential and mystery. And Poseidon, being his father, has a big role to play in protecting and guiding Percy.
Obviously, Zoe and Percy are the main characters. Zoe is the one with the crush, and Percy is the object of her affection.
Well, since it's a Percy - centered fanfiction, Percy is surely one of the main characters. There might also be his friends like Annabeth, who is often by his side in the original stories, helping him out with her wisdom. Grover could also be there, as his loyal satyr friend. And depending on the plot of the fanfiction, there could be new characters introduced as well, or some of the gods from Greek mythology might play important roles too.
Annabeth is often a popular character. She could be in a story where she has to help Percy deal with his relationship with Poseidon. Maybe she gives him advice on how to handle Poseidon's overbearing nature or how to make the best use of the gifts Poseidon gives him.
Obviously, Percy and Poseidon will be main characters. Percy, as the son of Poseidon, is the one on the receiving end of the punishment. Poseidon, being the god of the sea, is the one dishing out the punishment. There might also be other characters like Annabeth, Percy's girlfriend. She could play a role in trying to help Percy understand why he is being punished and how to get out of the situation.
In addition to them, other characters from the Percy Jackson series might also make appearances. For example, Grover could be involved as Percy's friend. However, the core of the fanfiction usually revolves around Sally, Poseidon and Percy. Their relationships, like Sally's love for Percy and Poseidon's fatherly connection (or lack thereof in some interpretations), are what drive the story. These characters are often developed further in fanfiction, showing different sides of them compared to the original books.
Obviously, Percy and Poseidon are the main characters. Percy, the young demigod with his courage and powers, and Poseidon, the powerful god of the sea.
