What could be an interesting plot for a Percy Jackson and NCIS crossover fanfiction?

One possible plot could be that the Greek gods, noticing the powerful threats the Avengers face, send Percy Jackson and his friends to help. Percy could use his water powers to assist in putting out fires during a battle like the one in New York. Meanwhile, Thor could be intrigued by Percy's connection to Poseidon and they could exchange stories about their godly fathers.

A great plot could involve a prophecy in both the Naruto and Percy Jackson worlds. The prophecy states that only by combining the powers of the ninja and the demigod can a great evil be defeated. Naruto and Percy are chosen to fulfill this prophecy. Along the way, they face challenges like trying to understand each other's cultures. Naruto has to get used to the Greek pantheon, and Percy has to learn about chakra. They also have to deal with their own insecurities. For Naruto, it could be his fear of not being strong enough without the Nine - Tails' power, and for Percy, it could be his fear of losing his friends in the battle.

One possible plot could be that the Volturi from Twilight discover the existence of demigods from the Percy Jackson world. They see the demigods as a threat to their vampire supremacy. Percy and his friends have to team up with some of the more friendly vampires, like the Cullens, to fend off the Volturi. This would bring together the magic and powers of both universes in an epic battle.

One idea could be that the demigods from Percy Jackson end up in Riverdale due to some sort of magical mishap. Percy could be confused by the strange mortal world of Riverdale, with its own set of secrets and drama. Meanwhile, the Riverdale gang could be in awe of the demigods' powers. For example, Archie might be inspired by Percy's heroism and try to be more like him in facing the town's problems.

Well, it could start with a magical accident. In the Percy Jackson universe, a spell gone wrong sends Percy, Annabeth, and Grover into the land of Alagaësia from Eragon. There, they discover that the demigod powers Percy has are seen as a strange and new form of magic. Eragon is initially suspicious of them but realizes they can help in his fight against Galbatorix. They combine their skills, Percy's water - controlling powers and sword - fighting skills, along with Annabeth's strategic mind and Grover's nature - sensing abilities, with Eragon's dragon - riding and magic - wielding skills to take on the dark forces.

Well, perhaps there's a villain in the Percy Jackson universe who discovers that the iCarly web show has a huge following and decides to use it as a way to spread chaos. The demigods have to team up with the iCarly crew to stop this. The iCarly gang has to learn about the world of Greek mythology really fast and help the demigods navigate the modern world of technology and media to defeat the villain.

A plot might involve the Maze Runner characters being transported to Camp Half - Blood. Thomas and his friends would be shocked to find out about the existence of demigods, Greek gods, and the magical world. The Maze Runner group could learn combat skills from the demigods, like sword fighting. Meanwhile, the demigods would be intrigued by the technology and the complex maze - like problems the Maze Runner characters had to face. They could all work together when an ancient evil from the Percy Jackson world, sensing the new arrivals, decides to target the combined group, believing they could be a threat to its plans.

One interesting plot could be that the magical worlds of Hogwarts and Camp Half - Blood somehow merge. Harry Potter and his friends find themselves in the world of Percy Jackson, facing off against mythological creatures they've never seen before. Maybe they have to work together to stop a common enemy that threatens both their worlds, like an ancient dark magic that is starting to corrupt the gods and the wizards alike.

One possible plot could be that the demigods from Percy Jackson's world are somehow transported to the Glade in the Maze Runner. Percy, Annabeth, and Grover could use their unique skills. Percy's water - controlling abilities could help with finding water sources in the Glade or even fighting the Grievers in a new way. Annabeth's strategic mind would be useful in trying to figure out the maze, and Grover could sense any nature - related secrets in the strange new environment.

Well, perhaps the H2O girls are being chased by some sea monsters that are normally under Percy's jurisdiction. Percy and his demigod friends come to their rescue. In the process, the H2O girls learn about the world of Greek mythology and demigods. They could then join forces to fight off other threats that come their way, like an evil sea god who wants to take over both their worlds.
