Another plot idea is that their baby gets lost in a magical realm. Percy and Annabeth then embark on a quest to find their baby. Along the way, they meet new characters and face various trials. This would test their relationship as a couple and their capabilities as parents.
One possible plot could be the challenges they face as new parents. Maybe they have to protect their baby from an old enemy who resurfaces. For example, a monster from Percy's past might target their child because of Percy's status. So they have to use their skills and the help of their friends to keep the baby safe.
Perhaps the story could be about how Percy and Annabeth adjust to parenthood. Annabeth might be overly cautious because she's used to planning and strategizing, while Percy is more laid - back. Their different parenting styles could lead to some humorous and also some tense moments. The baby could also start showing signs of being a hero from a very young age, like having an uncanny ability to find lost things, which is a sign of the baby's connection to the demigod world.
One possible plot could be Percy and Annabeth adjusting to life as new parents. They might face challenges like protecting their baby from mythological threats. For example, they have to keep the baby safe from monsters who might target the child because of its parents' heroic status.
Well, their son could inherit Percy's water - controlling abilities and Annabeth's wisdom. Maybe he'd be a hero in his own right, facing new threats in the world of the fanfiction. He could grow up trained by his parents and their friends, learning combat and strategy.
It could be a beach day scenario. Maybe they are having a day off from their adventures and just relaxing on the beach in their bikinis and swim trunks, enjoying the sun and having some light - hearted conversations.
One possibility could be that they are in a school setting where they have to wear uniforms. Percy might constantly be getting in trouble for not following the uniform code properly, like having his tie askew or his shirt untucked. Annabeth, being more organized, tries to help him out. This could lead to some comical moments as well as deeper conversations about fitting in and following rules.
One possible plot could be their daily adventures in a new city. They might face challenges like dealing with strange neighbors or finding new jobs. Maybe they also have to hide their demigod powers from the normal humans around them.
One possibility could be that they are banished due to a false accusation. Maybe someone in the camp frames them for a serious crime they didn't commit, like stealing a powerful magical artifact. So, they are forced to leave and then have to prove their innocence while on the run from those who banished them.
Well, perhaps Percy takes Annabeth on a quest to a special location, like an ancient Greek ruin they've always wanted to explore. During this adventure, he finds the perfect moment when they're alone and surrounded by the beauty of the place to pop the question.
One possible plot could be that Percy and Annabeth are on a quest in Paris. They might be searching for a lost Greek artifact that has somehow ended up in the city. Along the way, they explore the famous landmarks like the Eiffel Tower and Louvre Museum, all while facing various monsters in disguise among the tourists.
The fanfiction could also focus on the relationship between Annabeth and Percy during this time. They might have disagreements on how to handle the situation. For instance, Percy might want to keep Annabeth safe at all costs and not let her go on any dangerous missions, while Annabeth feels that she needs to be involved to protect their child. This could lead to some tension between them, but in the end, they would work through it and become even closer as they anticipate the birth of their baby.
