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.
Nico di Angelo is another character that shows up a lot. He could be in a story where he has some sort of secret knowledge about Poseidon that he shares with Percy. Nico's dark powers and his own complex relationship with the gods could add a new layer of depth to the fanfiction.
Annabeth would definitely be involved. As Percy's girlfriend, she is often by his side during his adventures. She could be the one who witnesses Poseidon's pride towards Percy and helps Percy understand the significance of it. Grover, Percy's best friend, is also likely to be there. He might provide some comical relief during the serious moments when Poseidon is showing his pride. Also, other demigods from Camp Half - Blood like Jason, Piper, and Leo could be involved. They could be in awe of Percy's new - found status with Poseidon and might interact with him differently because of it.
Annabeth could be there. Since she is Percy's friend, she might come in to help Percy when he's in trouble during his growth with Poseidon. Also, other demigods from the camp could show up. They might be curious about Percy's special relationship with Poseidon and how it's affecting his growth.
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.
A common theme is the exploration of Percy's heritage. Since Poseidon is his father, many fanfics dig deeper into what that means for Percy, like how he can access more of his godly powers. For example, some fanfics have Percy learning to control the tides in ways he hadn't before.
In fanfictions, Poseidon often interacts with baby Percy in a very gentle and protective way. He might use his powers to create a safe environment for Percy, like a special underwater grotto where Percy can be hidden from danger. Sometimes, he sends sea creatures to watch over Percy, like dolphins or friendly sea nymphs.
Many fanfictions center around Poseidon's role in prophecies. In the Percy Jackson world, prophecies are a big deal. So, in these stories, Poseidon could be trying to manipulate or fulfill prophecies that involve Percy. He might be working with or against other gods to ensure a certain outcome. There are also plots where Poseidon discovers new secrets about Percy's destiny and has to take action to either protect or guide him in a way that wasn't in the original narrative.
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.
I'm not sure if there are any extremely popular ones in the mainstream sense. Since mpreg fanfiction is a very specific and often a bit of a niche area. However, within the Percy Jackson fanfiction community, there might be some well - known ones among those who are interested in this particular genre. You would probably need to search in dedicated fanfiction websites and forums to find out.
