Who could be Percy's secret wife in a fanfiction?

Annabeth Chase is a popular choice. Given their relationship in the original series, many fanfictions continue their story and have them get married.

It could be a mark that represents his family or a long - lost heritage. Perhaps it's a crest that has been passed down through generations in his family but he has to keep it secret for some reason, like it might draw unwanted attention from certain enemies or factions in the story.

Maybe Percy's secret talent in fanfiction could be that he has the ability to communicate with sea creatures on a much deeper level than shown in the original story. He can not only understand their simple messages but also have complex conversations with them, getting valuable information about hidden treasures or upcoming threats in the ocean.

Wanda could be an interesting candidate. They both have a deep connection within the Avengers. Wanda's powers could be linked to Natasha's in some fanfic scenarios. For example, Wanda could use her powers to shield Natasha and her relationship from the prying eyes of the world, while Natasha uses her skills to protect Wanda from physical threats.

It could be Annabeth's sister (if she had one). A new character who has all the intelligence of Annabeth but a different personality. Percy might be drawn to her because she challenges him in a different way. Maybe she's more into art and architecture rather than just battle strategies like Annabeth, and Percy finds this new perspective fascinating.

It could be Hades. He might not like the idea of Percy, a son of Poseidon, being friends with Apollo. Hades could see it as a threat to his own power or plans in the underworld.

It could be an old acquaintance that Percy had a brief relationship with. Maybe someone he met during one of his adventures and then lost touch with, but she later discovers she's pregnant and decides to keep the child a secret from Percy for various reasons.

The mother could also be a completely new character created specifically for this fanfiction. She might be from a different realm or have some special powers. And her relationship with Percy could be a complex one, filled with secrets and misunderstandings that led to the situation of having a secret daughter.

Maybe it's a fan who has been observing Percy from afar. This person could have created the fanfiction based on their own interpretations of Percy's personality, actions, and the things they've heard about him. They wanted to create a story that they felt was true to Percy in some way.

It could also be a story that delves into Percy's past. There might be some events from his childhood or early days that he has never shared. The fanfiction could be a creative exploration of those untold stories, including his relationships with his family or how certain experiences shaped him into the person he is now.
