Another possibility is that it could be a god in disguise. Given the complex relationships between demigods and gods in the Percy Jackson universe, a god could have fallen in love with Annabeth and fathered her child. This would bring all sorts of divine drama and complications to the fanfic.
It could also be another demigod. Maybe someone she met during a new adventure or quest. This would add an interesting twist to the story as they'd have to figure out their relationship while also dealing with the pregnancy.
It could also be a new character introduced in the fanfiction. Maybe a powerful demigod from another camp who Annabeth meets during a diplomatic mission. This would create a whole new set of drama and conflict, as Annabeth would have to deal with her feelings for Percy and this new person, as well as the implications of having a child with someone other than Percy.
The most obvious choice would be Percy Jackson. Given their long - standing relationship in the original series, it makes sense that he would be the father. Their relationship has been through so much, and having a child together would be a new chapter in their story.
Most likely, Percy could be the father. They have a strong relationship in the original series, so it would be a natural choice. Their chemistry and shared adventures could be the basis for a story where they start a family together.
One possible plot could be that Annabeth and her partner (maybe Percy) discover she's pregnant unexpectedly. They then have to deal with the shock while also facing the challenges in their world, like potential threats from monsters who might see a pregnant demigod as an easy target. They would also need to prepare for the baby's arrival, which includes finding a safe place to raise the child in a world full of danger.
It could also be someone new, a character created specifically for the fanfiction. Maybe a powerful new demigod who catches Annabeth's eye, and their relationship leads to the pregnancy.
One possible plot could be that Annabeth has to balance her pregnancy with her heroic duties. Maybe she's still involved in some sort of quest but has to be more cautious. Her friends, like Percy, would be very protective and help her out.
It might be an old enemy who somehow managed to get her in this situation as part of a devious plan. This would add a lot of drama and conflict to the story.
One possible plot could be that Annabeth and Percy Jackson are finally in a stable part of their lives. They are married and settled. Then Annabeth discovers she is pregnant. The story could follow their journey of preparing for the baby, with Percy being overly protective and Annabeth trying to balance her normal activities with the new changes in her body. They might face challenges like dealing with the reactions of their demigod friends, some being excited and others worried about how a baby would fit into their dangerous world.
