Another concept is the exploration of different character backstories. Fanfiction often delves deeper into a character's past that wasn't fully explored in the original books. For instance, we could see more about Nico di Angelo's time in the Underworld before he joined Percy and the others, and how that shaped his personality and powers.
One idea could be exploring Percy's life if he had a different godly parent. For example, if he was a son of Hades, how would his powers and his relationship with the other demigods change? Another idea is to write about a time - travel adventure for Percy and his friends, where they go back to the era of the first Olympians.
Another plot could be that the bullying is actually part of a scheme by a minor god who is jealous of Percy. So Percy has to figure out the real reason behind the bullying while also trying to keep his demigod identity a secret from the mortal world. He might start to notice strange things happening around the bullies, like they seem to have unnatural strength at times, which leads him on a quest to uncover the truth.
Well, time - travel is a cool concept in percy jackson fanfiction. Imagine Percy going back in time to change some crucial events in the history of the demigods. Also, there are fanfictions that focus on Percy having new powers or abilities. This could be because of some new magical artifact or a special training he undergoes. And of course, the idea of Percy having to adapt to a completely different camp, like a Roman - Greek hybrid camp, is really engaging.
One idea could be Percy and his friends getting trapped in a virtual version of the Underworld created by a new villain who is a master gamer. They have to use their real - world skills and in - game cheats to escape.
One idea could be Percy having to face a new, unknown threat that even the Olympians are afraid of. Maybe it's a primordial force that was locked away long ago and is now breaking free. Another plot could be Percy getting stranded in a different realm, like the Underworld, and having to find his way back while dealing with the local challenges and creatures there. Or perhaps Percy has to team up with some of his old enemies to fight a common, greater foe that endangers both the demigods and the Olympians.
One interesting concept could be a darker version of Percy's powers. For example, instead of just controlling water, he might be able to use it in more menacing ways, like creating water blades that can cut through almost anything. Another concept could be a darker side to his relationships. Maybe his friendship with Grover takes a turn, and there's more conflict and distrust. Also, a darker Percy might have a different view on the gods, perhaps feeling more resentful towards them for all the hardships he has faced, instead of just being the hero who blindly follows their orders.
One interesting concept could be the modernization of the Percy Jackson world in a gaming context. For example, how the demigod powers are translated into gaming abilities like special moves or skills. Another could be the creation of new quests within the game that are inspired by the original books, such as finding lost artifacts from Greek mythology in a virtual world.
A cool concept might be a modern - day mortal who somehow drops into the world of Percy Jackson. Maybe they have some hidden knowledge or ability that helps them survive and make an impact. They could introduce new technology or ideas from the real world that the demigods have never thought about, like advanced medical knowledge or new forms of communication.
One interesting concept could be alternative character backstories. For example, in some fanfictions, a character might have a different origin story that ties into the Greek mythology in a new and unexpected way. Maybe a minor god has a much larger role in the fan - created story.
One interesting concept could be the combination of different demigod powers. For example, a character might combine the water - controlling powers of a Poseidon - related demigod with the wind - controlling powers of a Zeus - related one. This can lead to really cool and unique abilities that are not seen in the original series.
