What are some interesting ideas in Percy Jackson crossover lemon fanfiction?

One idea could be a crossover with the Harry Potter universe. Percy could visit Hogwarts and have to deal with both magical and mythological threats. Maybe he'd team up with Harry to defeat a common enemy that combines dark magic and ancient Greek monsters.

One idea could be that Percy ends up in the Underground world of Undertale. He might use his water powers in unique ways against the monsters there. For example, he could create water shields to block attacks from the more aggressive monsters like Undertale's Flowey. Another idea is that Sans could somehow end up in the Camp Half - Blood from Percy Jackson. Sans' laid - back attitude would be a contrast to the usually intense and heroic demigods at the camp.

One idea could be that Percy and his friends get transported into an anime world like Naruto's. Percy could use his water powers in the deserts of Suna and have epic battles against the sand ninjas. They might also learn new skills from the Naruto characters, like chakra control, and in return, teach them about Greek mythology.

A crossover with Harry Potter could be cool too. Percy could visit Hogwarts and participate in a Triwizard Tournament - like event. He'd be the outsider with his unique demigod powers, and there could be a lot of fun interactions between him and the Hogwarts students, like Hermione being intrigued by his abilities.

One idea could be that Percy and his friends from Camp Half - Blood are somehow transported into the Doom universe. Maybe they have to fight the demons there using their demigod powers and the weapons they find in the Doom world. For example, Percy could use his water powers to fight the fire - based demons.

One idea could be a crossover where Percy Jackson accidentally stumbles into the world of 'Rough Lemon'. Maybe he has to use his demigod powers to solve the unique problems there. For example, he could use his water - controlling abilities to deal with a drought that is plaguing the 'Rough Lemon' land.

One idea could be Percy using his water powers in a unique way against Medusa. For example, he could create a water shield that reflects Medusa's petrifying gaze back at her in a fanfiction. Another could be a scenario where Medusa, instead of being an enemy, teams up with Percy to face a greater threat.

A plot could be that Sally Jackson plants a lemon tree in her garden that turns out to be a gift from a minor goddess. The lemons from this tree have the power to give those who eat them the ability to see through illusions for a short time. Percy uses these lemons to his advantage when he is on a mission to retrieve a powerful artifact that is guarded by a monster that uses illusions to protect it.

One idea could be that Artemis takes Percy on a special quest that involves protecting a sacred grove that is being threatened by an ancient evil. This would test Percy's skills in a new environment and also show how he interacts with Artemis' more nature - centered values.

Another interesting plot could involve a prophecy that links the Dragonborn and Percy. They both have destinies to fulfill, and their paths cross when they realize that they need to combine their powers. For example, the Dragonborn's combat skills and the ability to absorb dragon souls, along with Percy's control over water and his demigod powers, could be used to defeat a dark force that threatens both their worlds. It could also explore how the different magic systems interact, like the magic of Skyrim and the magic in the Percy Jackson universe.
