Well, it could be that the old heroes, like from Greek mythology, are brought back to life in modern times and meet Percy Jackson. They might initially be confused by the modern world Percy lives in. For example, they could be shocked by things like cars and cell phones. Then, they might team up with Percy to fight a new threat that endangers both the old and new worlds of heroes.
Perhaps in this fanfiction, the old heroes are in a sort of limbo or afterlife, and Percy accidentally stumbles upon them. They could be in a state of unrest because something in the modern world is disrupting the balance of their existence. Percy then has to figure out how to help them while also dealing with his own problems in the Camp Half - Blood world, like conflicts with other demigods or new monsters that are emerging.
The plot could involve the old heroes seeing Percy as a successor to their legacy. They might test him in various ways to see if he's worthy of their respect. Maybe they set up challenges for him related to their own heroic deeds from the past. And in the process, Percy learns a great deal about the history of heroism and gains new skills from these old heroes.
Hercules is a very likely old hero. He was super strong and had many great adventures. Percy could learn a lot from him about strength and courage.
The old heroes would probably be in awe of Percy's powers at first. After all, he has unique abilities that they may not have seen before. Percy, on the other hand, would be respectful but also curious about their tales. They might exchange stories of their adventures, with Percy listening intently to the old heroes' accounts of battles in ancient times.
In fanfiction, when Percy meets the old heroes, it could be a really cool adventure. Maybe they would share their tales of glory, and Percy would be inspired. He could also find out about some long - lost secrets of the demigod world that only the old heroes knew. This could help him in his future quests, like facing new and more powerful monsters. The old heroes might also test Percy to see if he's worthy of their knowledge and respect.
In a Percy Jackson meet old teachers fanfiction, there could be a lot of reminiscing. Percy might recall the tough lessons he learned from his old teachers at Camp Half - Blood. Maybe he meets Chiron again, and they talk about the old days of training demigods. It could also be a chance for Percy to see how much he has grown since those early days under their guidance.
He might meet some native Alaskan spirits. These spirits could be like the nature spirits he has encountered before but with their own unique Alaskan characteristics.
He could meet some Aboriginal heroes or spirits. They might have their own powers and knowledge that Percy can learn from.
Percy might encounter Baba Yaga. She is a well - known figure in Russian folklore. She could be an adversary, testing Percy's skills and his knowledge of the magical world. Or perhaps she could be a source of information if Percy manages to earn her respect. He could also meet the Rusalki, water nymphs from Russian mythology. Given Percy's connection to water, it would be interesting to see how he interacts with them.
One possible plot development could be Percy and his friends facing a new, even more powerful enemy. Maybe an ancient primordial being that was previously sealed away has been awakened. For example, a new Titan or a primordial chaos entity. Another development could be Percy exploring his new powers or abilities that he might have gained after the events of Heroes of Olympus. He could be training other demigods as well, passing on his knowledge and skills.
In an 'Avengers meet Percy Jackson' fanfiction, there could be a lot of interesting character interactions. For example, Tony Stark might be intrigued by Percy's ability to control water and try to figure out a scientific explanation for it. Natasha could see Percy as a young and powerful ally and train him in some hand - to - hand combat techniques from the Avengers' arsenal. And Percy could introduce the Avengers to the world of Greek gods and monsters, which would be a whole new concept for them.
Well, it could be a story where Jackson and Ethan meet by chance at a concert. They start chatting and find out they have a lot in common, like their love for a certain band. Then they become friends and start going to more concerts together.
