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.
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.
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.
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.
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.
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.
Yes, there might be such fanfictions out there. You can try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net. However, the idea of Zoe cheating on Percy might be a bit unorthodox as their relationship in the original context might not typically lead to such a plot.
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.
There's also 'Percy and Artemis: Childhood Memories' which focuses on the unique dynamic between them. It shows how Percy's carefree nature contrasted with Artemis' more reserved self during their childhood. The author does a great job of building their relationship gradually throughout the story.
Well, at first, they could be at odds with each other. Zoe might see Percy as too impulsive, while Percy might think Zoe is too reserved. But as they get to know each other better, they find common ground. For instance, they both care deeply about their friends and their world. This understanding could lead to Percy falling in love with Zoe. He might start to do little things for her, like bringing her a flower he found during their travels or protecting her in battles without her asking.
