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.
A cool plot could be that a group of demigods discover a new game that is actually a portal to a lost realm of the gods. They enter the game to explore this realm, but once inside, they find that they have to complete a series of extremely difficult quests to get back out, all while being hunted by a powerful entity within the game.
Maybe there could be a plot where Percy enters a gaming tournament in the mortal world, but the games are all secretly designed by the gods to test the demigods' abilities. He has to face off against other demigods and some mythical creatures that are programmed into the games.
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 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.
One idea could be Percy having to face a new and powerful monster that is a combination of different mythological creatures. For example, a chimera with the head of a hydra. This would create a unique and challenging battle for him.
One idea could be Percy using his gaming skills to outwit monsters in the real world of the Percy Jackson universe. For example, he might use strategies from strategy games to plan attacks against a horde of mythical beasts. Another could be Percy getting trapped in a virtual world that has elements of both the gaming world and the Percy Jackson mythos, and he has to find his way out by solving puzzles based on Greek mythology.
Maybe in the fanfiction, Percy discovers a virtual reality game that is actually a portal to different parts of the mythological world. He has to complete quests within the game to save his friends in the real world. The game could have glitches that are caused by the interference of the gods, adding an extra layer of mystery.
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.
Perhaps there could be a plot where a powerful and dark gamer is trying to take over the world through the gaming platforms, and Percy, along with his demigod friends, has to enter the games to stop this evil plan. They could face challenges like corrupted game levels, glitched enemies that are super - powerful, and a race against time to prevent the dark gamer from achieving their goal.
One idea could be that Fem Percy, with her unique skills, has to prove herself to the Olympians. Maybe she goes on a quest to retrieve a powerful artifact that was stolen from Olympus and in the process, she has to face off against various mythological creatures. Along the way, she forms an unexpected bond with one of the Olympians, perhaps Hermes, who helps her navigate the tricky world of the gods.
A powerful demigod who has turned to the dark side and uses his gaming skills to hack into the gods' systems. He wants to rewrite the rules of the world and become a god himself.
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.
