Make the OC from a different culture or time period. Let's say the OC is from an ancient civilization that has long - lost knowledge. Percy has to learn about this culture to understand the OC better, and their relationship grows as he does. Their love is also a journey of discovery about different worlds and ideas. They might face challenges like cultural differences and misunderstandings, but that makes their relationship more interesting.
The OC could have a really unusual power. For example, the ability to communicate with animals in a very special way that no one else can. Percy is intrigued by this and it sets their relationship apart. They bond over using this power to solve problems or get out of tricky situations.
Give the OC a strong personality trait that clashes with Percy's at first. For instance, the OC could be extremely cautious while Percy is more impulsive. They start off butting heads but then learn from each other. As they grow, their relationship becomes unique because they've changed each other for the better. Their love story is about two very different people finding common ground and falling in love in the process.
In a 'Percy Jackson and a OC love fanfiction', you could also use the element of sacrifice. Let's say the OC is in danger of being captured by a powerful enemy. Percy risks everything to save her. This act of selflessness makes the OC see Percy in a new light. On the other hand, the OC could also sacrifice something for Percy, like giving up a chance to go back to her old life in order to stay with him at Camp Half - Blood. These sacrifices deepen their connection and lead to a stronger, more loving relationship.
Well, it could start with mutual respect. For example, Percy respects Artemis's power and her role as a goddess. Artemis, in turn, could come to respect Percy's courage and his ability to survive against all odds. They could then start to work together on small tasks, like protecting a particular area from monsters. As they spend more time together, they might start to trust each other more, and their relationship could grow deeper.
A slow - burning friendship could be developed through shared experiences. Maybe they are both trapped in a strange magical realm for a while. During that time, they have to rely on each other to survive. Hera could use her powers in ways Percy has never seen before to protect them, and Percy could use his quick thinking and demigod abilities to find food and shelter. This shared struggle would bring them closer together.
In fanfiction, their relationship might develop through a shared goal. Say there's a powerful magic item that both Percy and Medusa want. They have to work together to get it. Along the way, Percy learns about Medusa's past and the reasons she became what she is. Medusa, in turn, sees Percy's courage and determination, and they start to respect each other. This mutual respect could then turn into an unlikely friendship or at least a begrudging alliance.
The relationship could start with hostility. Percy is aware of Circe's reputation for turning men into animals. But then, as they are forced to work together to overcome a mutual obstacle, like a powerful monster attacking Circe's island, they begin to see each other in a new light. Percy realizes Circe has her own reasons for her actions in the past, and Circe sees Percy's courage and loyalty.
The relationship could start with Percy being curious about Kronos. He could research the Titan in the hopes of finding a weakness. This initial interest could lead to some strange interactions, like Kronos communicating with Percy through visions. As Percy delves deeper, he might start to understand Kronos's motives, which could create a complex dynamic.
One way to develop their relationship is by having them go on a long - term quest together. On this quest, they are isolated from the rest of the camp and have to rely solely on each other. At first, they might argue a lot because of their different personalities. Percy is more laid - back and impulsive, while Thalia is more serious and cautious. But as they face various challenges, like fighting off hordes of monsters or solving ancient riddles, they start to adapt to each other's ways. Thalia might learn to be a bit more spontaneous from Percy, and Percy could become more cautious because of Thalia. This mutual growth and adaptation would strengthen their relationship.
It can be developed through communication. For example, Percy could write letters to Calypso (even if she's on her island). These letters could express his true feelings for her, and Calypso could respond in some magical way. This exchange of thoughts and emotions would deepen their relationship.
By having them share common goals. For example, protecting the sea and its creatures. This would force them to interact and gradually understand each other better.
The relationship can start with mutual distrust. Percy has seen Hera's manipulative side before, and Hera might not fully trust Percy at first. But then, they could be forced to work together on a task. For example, saving a group of demigods from a powerful enemy. As they face challenges side by side, they begin to respect each other's abilities. Percy realizes that Hera has her reasons for her actions, and Hera sees Percy's courage and loyalty.
