In a Percy Jackson fanfic with a sick Octavian, one possibility is that the sickness is some sort of magical or divine affliction. This could tie into the overall mythology of the series. For example, it could be a curse from an angry god because of something Octavian did. His struggle with the sickness could then be a journey of self - discovery and redemption. He might start to see the error of his ways, especially if he has to face his mortality. And this could have a ripple effect on the relationships between the demigods of the Greek and Roman camps.
Perhaps Octavian's sickness is a way for the author to explore themes of forgiveness and acceptance. He could be a really unlikable character at first, but as he gets sick, he starts to change. The other characters see this change and start to question their own prejudices against him. His sickness could be a catalyst for him to make amends with those he has wronged in the past. And the story could end with him either fully recovered and a changed person, or with his death being a turning point for the other characters to become better.
Well, it could be that the sick person has a unique power that is making them ill. Percy and Will have to figure out how to control or suppress this power while also treating the illness. Maybe the power is related to a prophecy that they need to fulfill. So, not only are they trying to save the person's life, but also trying to understand the bigger picture of what this all means for the world of demigods.
If Percy Jackson were to join the Avengers, it would be chaos at first. Percy is used to operating on his own or with a small group of demigods. The Avengers are a big, organized team. However, his powers would be a great asset. He could use his water manipulation to put out fires caused by the Hulk's rampages or to flood areas to stop advancing enemies. His loyalty and courage are also top - notch, which the Avengers would come to respect. His connection to Poseidon might also bring in some new elements to the story. Maybe Poseidon could offer some assistance or advice in certain situations. And Percy's experiences with different gods and monsters would give the Avengers new perspectives on the threats they face.
Well, for starters, there could be a lot of reminiscing. Demigods would talk about their old teachers and the lessons they learned. Maybe there'd be some friendly competitions like a mini - quest challenge just for fun. Percy could show off some new water - bending tricks he learned. And of course, there'd be lots of hugs and catching up on relationships, like whether so - and - so is still dating that other demigod.
Well, it might start with Percy and the Kanes being suspicious of each other at first. But as they get to know about the threats looming over both their worlds, they start to work together. Percy could teach the Kanes about Greek mythology and his experiences with the gods, while the Kanes could share their knowledge of Egyptian magic. They could also explore each other's territories, like Percy showing them Camp Half - Blood and the Kanes taking him to the House of Life.
In a 'Percy Jackson leaves earth' fanfic, he might end up in a whole new realm of gods and monsters. Maybe he discovers a parallel universe where the rules of the Greek gods are different. He could encounter new versions of his friends or enemies and have to learn new powers to survive.
In such a fanfic, Percy might receive Triton as a sort of gift or ally. Maybe Triton would help Percy in his underwater adventures, like guiding him through the darkest parts of the ocean where no normal demigod could go. They could also team up to fight against some powerful sea monsters that are threatening the underwater world or the surface world connected to it.
He could be worshipped. If Percy is mistaken for a god, the mortals around him might start worshipping him. They would offer sacrifices and build temples in his honor. This would put Percy in a difficult position as he doesn't want to deceive people but also doesn't want to anger the real gods.
In a Percy Jackson family vacation fanfic, there could be a lot of adventure. For instance, they could be traveling through a forest and stumble upon an ancient, lost temple. Inside, there are puzzles and traps that they have to overcome together as a family. Percy would use his skills, his mom could offer her wisdom, and Poseidon might show up to help at a crucial moment. And of course, there would be some humorous moments, like when they try to cook normal food but end up with some sort of magic - infused meal because of a spell gone wrong.
In the fanfic, there could be a big revelation later on that it was all a misunderstanding. Maybe some sort of mind - control magic was involved. But until then, Percy would have to face many challenges alone. He might even start to question his own worth and abilities. For example, he could be hesitant to use his powers, thinking that if his friends could betray him, maybe his powers are part of what made them turn away. It would be a very emotional and angsty journey for Percy as he tries to figure out what went wrong and how to fix it.
