Well, it could be about Percy and Jason having a sparring session. Maybe it shows their different fighting styles, like Percy's water - based powers and Jason's control over the wind and lightning. It might also explore their relationship as they compete, whether they start as rivals or friends.
In fanfic, Jason might learn about Percy's hidden talents or secrets. Fan writers sometimes come up with unique ideas like Percy having a special connection to a forgotten god or a new power. Also, he could learn about Percy's thoughts and feelings in various situations that the original books might not have covered as deeply.
Jason might be jealous of Percy's connection to the sea. Since Percy is a son of Poseidon, he has this unique and powerful bond with the ocean. In fanfic, this could make Jason, who might not have such a strong elemental connection, feel inadequate. So, his jealousy could be a big part of the story as he tries to find his own place and power.
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, it really depends on the context of the fanfic. If it's near water, Percy has a huge advantage as he can control water and heal himself with it. But Jason is no slouch either, he can control the winds and lightning. However, in many fan interpretations, Percy's combat experience and his ability to improvise might give him the edge.
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.
A fanfic could also put Percy and Jason in a modern - day setting. They could be students in a school together, trying to hide their demigod identities. But then some mythological threats start to emerge in the school, and they have to use their powers secretly to protect their classmates. This would be a fun twist on the traditional settings of the Percy Jackson series.
When writing a Jason Percy Bromance Fanfic, think about their differences and how they can complement each other. Percy is a son of Poseidon, so he has a connection to the sea, while Jason is a son of Jupiter and has powers related to the sky. You can use these differences to create interesting scenarios. For instance, they might need to use their powers in tandem to reach a hidden place. Also, don't forget to add emotional depth. Show their insecurities and how they support each other through tough times. This will make their bromance more believable and engaging for the readers.
