What would be an interesting plot for a Percy Jackson and Kickin It crossover fanfic?

One possible fanfic could start with Percy Jackson, on a break from his demigod adventures, stumbling upon the dojo from Kickin It. He's intrigued by the martial arts skills he sees. He decides to join in for a while, hiding his true identity. But soon, his demigod reflexes start to show and the kids at the dojo are both amazed and a bit suspicious. As he trains with them, he also starts to notice some strange magical auras around the place, which could be related to some minor godly influence.

The plot could involve a villain who has found a way to cross between the two worlds. This villain starts causing chaos in both the world of Percy Jackson, like turning demigods against each other, and in Eragon's world, by disrupting the dragon - rider bond. Percy and Eragon, being the main heroes, have to team up. They start by trying to understand each other's powers and the rules of their respective worlds. Along the way, they make new friends and allies from both worlds and face many challenges together until they finally defeat the villain and restore peace in both their worlds.

Well, it could be that the Voltron team somehow gets transported to the Percy Jackson universe. Maybe they end up at Camp Half - Blood and have to team up with the demigods to fight a common enemy, like a new type of monster that is a combination of a Galra and a Greek mythological beast. The Voltron lions could be seen as some sort of strange new magical creatures by the demigods.

The plot could involve Percy Jackson's world of Greek gods colliding with the Avengers' universe. Maybe the gods have some sort of issue that only the Avengers' powers can help with, or vice versa. For example, an ancient Greek monster has been unleashed in the modern world that the Avengers are struggling to defeat, and Percy and his friends come in with their knowledge of Greek mythology to assist. It could also be a situation where the Avengers are dealing with a threat that has its roots in Greek magic, and they need Percy's demigod powers to counter it.

One possible plot could be that Percy and his demigod friends are somehow transported to the Halo universe. They could team up with the Spartans to fight a common enemy, like a new kind of powerful monster that has emerged in the Halo world due to some strange rift between the two universes. Percy could use his water powers in unique ways, for example, to short - circuit some of the Covenant technology which might be vulnerable to water in this crossover scenario.

Perhaps there's a character crossover in a more unique way. A demigod in the Percy Jackson world has a distant relative who was cursed in the Diablo world. This demigod, through some magical accident, gets transported to the Diablo realm. Percy, worried about his friend, follows. In the Diablo world, they have to adapt to the darker and more brutal environment. Percy has to use his skills in a different way, like his water powers to cool down the hellish fires. They meet Diablo - like characters who may not be all bad, and together they try to break the curse and find a way back home.

A possible plot is that Voldemort discovers the existence of the demigods and tries to use their powers for his own evil purposes. He sends his Death Eaters to capture some demigods. Percy and his friends manage to escape and seek refuge at Hogwarts. At Hogwarts, they learn about magic in a whole new way while also teaching the wizards and witches about their own powers. The two groups then have to combine their skills, like the demigods' combat abilities and the wizards' spell - casting, to fight against Voldemort and his new - found allies from the world of Greek mythology.

One idea could be that the demigods from Percy Jackson's world end up in Forks for some reason. Maybe they are on a quest that leads them there. And they cross paths with the vampires and werewolves from Twilight. For example, Percy could use his water powers to fend off some danger that the Twilight characters are facing, like a wildfire started by a vampire's power going out of control. This would create an interesting dynamic as the two different mythologies collide.

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.

A cool plot might involve a character from the Percy Jackson series getting lost in the Kane world. For example, Percy could end up in the Kane world and not understand how their magic works. The Kane siblings would have to help him while also dealing with their own problems, like the threat of some dark magician. At the same time, Percy's friends from his world are trying to find a way to bring him back, leading to an interesting crossover of events and character interactions.
