They would be very loyal to each other. Since they are childhood friends, they have a long - established bond. For example, they would always defend each other in any situation. If someone said something bad about Zoe, Percy would be the first to stand up for her, and vice versa.
They would have a deep understanding of each other. They know each other's likes and dislikes from a very young age. Maybe Percy loves to climb trees and Zoe knows that, so she always makes sure there's a good tree for him to climb when they go to the park. And Zoe has a passion for painting, and Percy would always bring her new art supplies when he could. Their friendship is based on this mutual knowledge and acceptance.
One possible plotline could be that they grew up in a small town. As children, they might have shared a secret hiding place, like an old treehouse. They could have gone on little adventures in the nearby woods, facing small challenges together, like getting lost and finding their way back. And as they grow older, they start to realize that their friendship is something really special and precious.
In Percy x Zoe fanfiction, often there is a strong focus on their relationship dynamic. It could be a slow - burn relationship, with lots of tension and anticipation. For example, they might start as comrades and gradually develop deeper feelings.
Their different personalities make it appealing. Percy is more impulsive and action - oriented, while Annabeth is intelligent and strategic. In fanfiction, seeing how these two contrasting personalities interact as children is interesting. For example, Percy might rush into a situation and Annabeth has to use her wits to get them out of it.
Percy could be a brave and adventurous character, perhaps with some special abilities like being able to control water or having enhanced strength. Zoe might be a smart and resourceful female character, maybe with skills in tracking or archery. They could be from a fictional world full of magic and mythical creatures.
In a fanfiction, their friendship could start with a simple act of kindness. Percy could save Reyna from a minor accident. Reyna, being grateful, starts to see Percy in a different light. They begin to have small conversations, getting to know each other's likes and dislikes. Over time, they realize they have more in common than they thought. They support each other in their personal goals, like Percy helping Reyna with a project for the Roman camp and Reyna helping Percy with his relationships at Camp Half - Blood. This mutual support cements their friendship.
Their friends would probably be very surprised at first. Annabeth, for instance, might be a bit skeptical at first but would soon come around to offer help and support. Grover would be excited and might offer to be the baby's protector, using his nature - related skills.
They could interact in a very competitive way too. Maybe they compete in different tasks or challenges within the story. For instance, if there's a race to find a magical item, they both want to be the one to succeed first, but still have a deep underlying sibling bond. Percy might tease Zoe sometimes in a brotherly way, and Zoe would roll her eyes at his antics but secretly be fond of him. Their interactions would be a mix of typical sibling banter and deep emotional support for each other.
In many fanfictions, their childhood friendship is the foundation. It makes Hinata understand Naruto on a deeper level. For example, she knows his dreams and his pain from when they were young. This understanding helps her support him better as they grow older and their relationship develops.
A good fanfiction in this genre is 'Our Childhood'. It starts with their very first encounter and then progresses through their childhood years at Camp Half - Blood. It beautifully portrays how their friendship evolved over time. 'Percy and Annabeth: Childhood Tales' is another one. It has some really cute moments, like when they shared secrets as kids. It also shows how they learned to rely on each other in the face of danger even as children. And 'Kid - Time Friendship' is a fanfiction that highlights their unique bond that was formed during their childhood days.
A third theme could be the shared adventures they have as children. Whether it's facing mythical beasts or exploring unknown lands, their childhood adventures together help to strengthen their bond. This theme allows for a lot of creativity in terms of the settings and challenges that the authors can come up with.
