Another plot idea is that Percy is tricked into believing that a god is evil and needs to be slain. As he embarks on this journey, he gradually uncovers the truth that there is a greater, more sinister force manipulating him. He then has to decide whether to continue with his original plan or find a way to expose the real villain while also making amends with the god he thought was bad.
Maybe in the fanfic, Percy teams up with some unexpected allies, like a group of minor gods who also feel threatened by the more powerful gods' actions. Together, they form a plan to slay a corrupt major god, which involves traveling to different realms and facing various mythical creatures along the way. The story could explore themes of friendship and betrayal as they work towards their goal.
One idea could be Percy discovers a new power related to the elements and has to learn to control it quickly to save his friends from a powerful enemy. For example, if he gains the ability to manipulate fire, he might accidentally set things on fire at first.
A cool plot could be that the God of Death has gone rogue and is starting to take souls before their time. Percy, with his friends, has to find a way to stop the god. They would have to search for ancient artifacts that can control or at least influence the God of Death's actions. They'd face many challenges, like traps in the Underworld and battles with deathly minions.
In a fanfic, perhaps Percy and his friends accidentally stumble upon Medusa's lair while on a quest. But instead of immediately attacking, Medusa offers them a deal. She says she will give them a valuable clue to complete their quest if they help her get revenge on one of the minor gods who wronged her in the past. Percy and his friends then have to decide whether to trust Medusa or not.
Yes, in certain Percy Jackson fanfiction. Writers like to explore different aspects of his character and powers. Since Percy has such a strong connection to the demigod world and has faced numerous challenges involving gods, it's not a huge stretch in fanfiction for him to be portrayed as a God Slayer. This can add a whole new layer of drama and adventure to the story.
One idea could be that Percy has to hide his Titan heritage from the other demigods at Camp Half - Blood. He discovers new powers related to his Titan side that are different from his godly powers. For example, he might have the ability to control certain aspects of nature in a more primal way compared to his Poseidon - related powers.
One idea could be Percy discovers he has a new ability related to his gills that allows him to communicate with underwater creatures in a more profound way. Maybe he can understand their ancient languages and has to use this new skill to solve an underwater mystery that threatens both the sea world and the surface world.
A great plot for a 'Percy Jackson at School' fanfic would be Percy competing in a school - wide competition that is secretly a test by the gods. The tasks in the competition could be related to the skills he has learned in his demigod adventures, like sword - fighting or outsmarting a maze - like obstacle. Also, he could befriend a mortal student who starts to suspect there is something different about Percy and his friends, and Percy has to decide whether to reveal the truth or keep the mortal in the dark.
Perhaps being reborn as a child of Poseidon but with a twist. Instead of having the typical water - based powers, you have the power to communicate with sea creatures in a way that no one else can, like understanding their emotions and memories. Or being reborn as a demigod who has lost their memory but slowly regains it as they go on quests and face challenges, and each recovered memory reveals a crucial part of their past and a new power or ability.
Well, perhaps the succubus is sent by an enemy of the gods to disrupt Percy's relationships with his friends. She starts causing jealousy and strife among them by using her alluring powers. Or maybe she's tied to an ancient prophecy that Percy is involved in, and he has to either defeat her or convert her to the side of good to fulfill the prophecy.
One idea could be that Percy adopts a young demigod who has a very rare and powerful ability. Percy has to teach this new demigod how to control their powers while also protecting them from monsters who are after the new kid because of their potential. Another could be that the adopted demigod is from a different pantheon entirely, which causes some interesting cultural clashes and misunderstandings within the Camp Half - Blood environment.
