The fanfic could be about Percy and Annabeth's kids participating in a friendly competition within the camp. It's a series of challenges that test their physical strength, strategic thinking, and teamwork. Through this competition, they learn more about their own abilities and the importance of working together, while also having some fun rivalries with other demigod kids.
One idea could be their first meeting at a summer camp for demigods. Maybe Percy is lost and Annabeth, being the smart one even as a kid, helps him find his way around. Another plot could be them teaming up for a camp quest. They might face a minor monster together and learn to rely on each other's strengths, like Percy's courage and Annabeth's intelligence.
A great plot idea is that the child has a special connection to the sea, like Percy, but also has Annabeth's wisdom. So they use this combination to solve a mystery that has been plaguing Camp Half - Blood for years. For example, the mystery of why some demigods' powers are fading. Another could be that the child gets sent back in time and has to interact with their parents when they were younger. This could create some really interesting situations and challenges for the child.
A possible plot could involve a magical tournament where Percy and Annabeth are on opposing teams. Their rivalry gets in the way at first, but as the tournament progresses and they see the real threats emerging, they start to cooperate in a more covert way to ensure the safety of everyone involved.
A plot could involve Percy and Annabeth getting lost in a parallel dimension where the rules of their world are flipped. Percy's punk style is seen as a sign of royalty, and Annabeth's girly appearance makes her seem like a powerful sorceress. They have to navigate this new world, make alliances, and find a way back home. Or perhaps there's a mystery at Camp Half - Blood where only their combined skills - Percy's punk - inspired out - of - the - box thinking and Annabeth's girly charm that can disarm some of the more traditional demigods - can solve it. Another plot could be that they are sent on a mission to a far - off land where the local culture is very different, and they have to adapt their punk and girly personas respectively to blend in and achieve their goals.
Maybe they are at Camp Half - Blood during a rare, quiet day. They've been training hard and decide to sneak away to a secluded spot by the lake to take a nap. During the nap, a minor god or spirit visits them in their dreams, warning them of an upcoming danger to the camp. This then sets the stage for a new adventure for them.
Another plot could revolve around the challenges of raising a demigod baby. Percy and Annabeth would have to protect the baby from various mythological threats. They might face monsters that are after the baby because of its potential power. Also, they would need to figure out how to educate the baby about their demigod heritage in a world that is both dangerous and full of wonder.
Another plot idea is that there's a rift in the House of Hades that is slowly corrupting the place and they have to find the source of it. Along the way, they face their own inner demons. Annabeth might struggle with her insecurities about being smart enough to solve the mystery, while Percy battles with his fear of not being strong enough to protect Annabeth. As they overcome these personal struggles, they also get closer to solving the problem of the rift.
A plot could be set in a post - apocalyptic world where Percy and Annabeth are on opposite sides at first due to some misunderstanding. As the story progresses, they realize they need to work together to face the real threats in this dark new world.
One plot idea could be that Percy is so caught up in his own heroic deeds and adventures that he completely misses all of Annabeth's subtle hints of her feelings for him. Meanwhile, Annabeth tries different ways to get his attention, like helping him with his studies in a very flirtatious manner, but Percy just thinks she's being a good friend. Another could be Percy getting into a situation where he has to protect Annabeth without realizing his true feelings for her are deeper than friendship, and throughout the fanfic, his obliviousness slowly starts to fade as he gets closer to her in the face of danger.
In a fanfiction about their bickering, a plot could be centered around a magical item. Let's say they find a new weapon or artifact. Percy wants to use it right away to test its power, but Annabeth is worried about the potential consequences and unknown abilities of the item. This leads to their bickering. Additionally, they could bicker about their relationships with other characters. For instance, Percy is friendly with a new demigod who Annabeth is a bit suspicious of, and this causes tension and arguments between them.
