Perhaps they argue over a girl. They are both heroes and might have feelings for the same person. Jealousy and competition could spark an argument between them. Also, their loyalty to different camps, Camp Half - Blood and Camp Jupiter, could be a source of conflict. They might have different ideas on how to handle the relationship between the two camps, which would lead to arguments.
At first, it might show the tension between them due to Jason's jealousy. Jason could be distant or snippy with Percy. But as the story progresses, they might start to communicate. Maybe Percy notices Jason's jealousy and tries to reach out, which begins to thaw the ice between them.
Well, Percy has his water powers which are extremely versatile. He can control water in all forms, use it for defense and offense. For example, he can create huge waves to overpower enemies. Also, his connection to the sea is very deep and it gives him a constant source of power, which might make him stronger than Jason who mainly has wind and flight - related powers.
In some fanfictions, Jason might be jealous of Percy because Percy has a closer connection to certain characters. For example, if Percy has a special bond with Annabeth that Jason wishes he could have. Maybe Percy is more well - known among the demigods, and Jason, coming from a different camp, feels left out or envious of Percy's status.
In a 'Jason has a crush on Percy' fanfiction, the relationship might develop in a rather complex way. Jason's crush could make him act a bit strange around Percy at first. Percy might notice this and start to wonder what's going on. Meanwhile, there could be other characters who suspect Jason's feelings. This external pressure could either push Jason to confess sooner or make him more hesitant. If Percy has some feelings in return, they might start with small gestures like a lingering touch or a special look. But if Percy doesn't, he might try to gently let Jason down while still maintaining their friendship. As the story unfolds, new events and challenges could further shape how their relationship evolves, whether it becomes a romantic one or remains a strong friendship.
It might be a test of strength. They could both be trying to prove themselves, either to their friends or to some higher power in the fanfiction world. They want to see who is truly the stronger hero.
Maybe they end up in a draw. They both are strong in their own ways. Jason has his lightning powers and leadership skills. They might fight to a point where neither can gain an upper hand and decide to call it a tie.
Jason might be shocked at first. He could feel a sense of respect for Percy, knowing that those scars are the marks of his many battles and hardships. Maybe he would be more curious about Percy's past adventures that led to those scars.
At first, it might be rocky. Percy is more of a laid - back hero, Nico is the quiet and often misunderstood one, and Jason is the dutiful leader type. But as they spend more time together, they start to see the good in each other. Percy might teach them how to have fun and not take everything so seriously. Nico could show them the power of the underworld and its secrets. And Jason would bring a sense of discipline and strategy to their group.
However, Jason has his own set of powerful abilities. His control over lightning gives him a great offensive power, and his ability to fly can give him an advantage in both battle and mobility. In some fanfictions where the setting is more favorable to his powers, he could be considered the most powerful. For example, in a high - altitude battle or in a place where there are a lot of electrical sources he can draw power from.
