Percy Jackson and Kane Crossover Fanfic: What are some interesting plot ideas?

Maybe there could be a new threat that can only be defeated by combining the magic of the Greek demigods and the Egyptian magicians. For example, a powerful monster that is immune to the weapons of one group but vulnerable to the powers of the other. Percy and his friends would have to team up with Carter, Sadie and their crew to take it down. They would need to learn about each other's worlds and powers along the way, which could lead to some interesting character interactions.

One idea could be that the magic from the Kane Chronicles and the demigod powers in Percy Jackson's world somehow merge. For example, a powerful Egyptian spell might accidentally be cast on Camp Half - Blood, causing chaos among the demigods. Another could be a quest where Percy and Carter Kane have to team up to stop a common enemy that is threatening both their worlds, like an ancient primordial being that wants to destroy all forms of magic and heroism. Or perhaps Annabeth and Sadie Kane need to work together to solve a mystery that involves both Greek and Egyptian mythology, using their respective knowledge and skills.

Maybe there's a prophecy in both worlds that foretells of a great danger that can only be averted by the combined forces of the two groups. The characters could start having shared dreams about this danger. Annabeth, with her strategic mind, could team up with Sadie Kane to decipher the ancient texts that hold the clues to what's going on. They'd have to overcome their differences in magic systems and beliefs to succeed.

One idea could be that the demigods from Percy Jackson's world accidentally stumble into the realm of the Kane Chronicles. Maybe Percy, Annabeth and some of their friends are on a quest near a portal that leads to the Egyptian magical world. Once there, they meet Carter and Sadie Kane. They soon realize that there's a common enemy that is affecting both their worlds, like an ancient evil that was sealed away long ago but is now starting to break free. They have to combine their powers, the Greek magic and the Egyptian magic, to fight it off. For example, Percy's control over water could be used in creative ways in the Egyptian deserts, and the Kane's magic could help the demigods in understanding some new types of magical threats.

Maybe there's a magical artifact that has significance in both Egyptian and Greek mythology. The characters like Percy and Carter Kane have to team up. Percy could use his water powers and Carter his magic to navigate through various challenges. They might start off distrusting each other because of their different mythological backgrounds but then realize they need to work together to stop the artifact from falling into the wrong hands.

A plot could involve a powerful artifact that has connections to both Greek and Egyptian mythology. This artifact is being hunted by various forces. Percy and Carter both get wind of it independently. When they meet, they initially fight over who should take possession of it. But then they discover that the only way to keep the artifact safe and prevent it from being misused is to work together. Along the way, they also learn about each other's cultures and mythologies, which helps them respect and trust one another more.

One idea could be that the wizarding world discovers the existence of demigods. Harry and his friends team up with Percy and his crew to fight a common enemy that threatens both their worlds, like an ancient, powerful dark force that feeds on magic and the power of the gods. For example, a new kind of dark wizard who has made a pact with a minor, evil god.

One plot idea could be that Percy Jackson discovers a magical artifact that somehow links his world to the Marvel Universe. Thor senses the power of this artifact and comes to investigate, leading to a meeting with Percy. Meanwhile, the Avengers also get wind of it and think it could be a threat. So, they all end up in a big showdown where they have to figure out if they're on the same side or not.

A crossover could also involve a prophecy that links the two worlds. For example, a prophecy states that only the combined powers of a wizard from Hogwarts and a demigod from Camp Half - Blood can defeat an ancient evil that is rising again. Harry and Percy are the ones chosen, and they have to learn about each other's strengths and weaknesses in order to fulfill the prophecy. They could travel between the two worlds, recruiting allies from both sides.

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.
