What are some interesting plot ideas for a Magnus Chase x Percy Jackson fanfic?

A really cool plot could be that there's a prophecy that involves both of them. The prophecy says that only by combining their unique abilities - Percy's control over water and Magnus's connection to the Norse gods - can they save both the Greek and Norse mythologies from being wiped out by a new, unknown force. They have to go on a journey, meet various characters from both mythologies, and overcome many challenges along the way.

One idea could be a crossover where Percy and Magnus have to team up to defeat a common enemy that threatens both their worlds. Maybe a primordial being that can disrupt the balance of both the Greek and Norse mythologies.

Another idea is a setting where the two worlds are merging. Percy and Magnus find themselves in a strange new place that has elements of both Camp Half - Blood and the Hotel Valhalla. They have to figure out how to survive in this new world while also dealing with the chaos that the merging is causing. The characters from both series could interact in interesting ways, like Annabeth and Samirah comparing their knowledge of architecture and magic respectively.

One great fanfic is 'The Adventures Beyond Borders'. It combines the worlds of Magnus Chase and Percy Jackson in a really cool way. The characters interact in a believable manner, and the plot is full of action and adventure. It has some really exciting fight scenes and also delves into the relationships between the different characters from both series.

One interesting crossover could be the characters from both series teaming up to fight a common enemy. For example, Magnus and Percy joining forces against a powerful ancient monster that threatens both the Norse and Greek worlds. This would be exciting as they both have different powers and abilities that could complement each other.

One interesting crossover could be a quest where Magnus and Percy have to team up. They could combine their different powers, like Percy's water - based abilities and Magnus's connection to Norse mythology. For example, they might face a sea monster that has a connection to both Greek and Norse realms. Another could be a story where they end up in each other's worlds and have to adapt. Percy in the Norse world would be really fun to read as he tries to figure out the different rules and gods there, and vice versa for Magnus in the Greek world.

Loki could be a great villain. He's known for his trickery in Norse mythology. He could manipulate events to set Magnus and Percy against each other. Maybe he wants to cause chaos between the Norse and Greek worlds for his own amusement or to gain more power.

A good fanfic should have a well - developed plot. For example, it could involve a new threat that requires both Magnus Chase and Percy Jackson to team up. It should also stay true to the original characters' personalities. Percy is brave and impulsive, while Magnus is more of a reluctant hero, and these traits should be maintained.

One interesting plot twist could be that they find out they are related in some way through the complex web of mythology. Maybe there's a long - lost ancestor who was part of both Greek and Norse worlds. Another could be that they are forced to swap powers. Percy has to deal with Magnus's Norse magic and Magnus has to handle Percy's water powers. It would be really cool to see how they adapt.

One idea could be a quest where Magnus and Percy have to team up to retrieve a powerful artifact that is causing chaos in both their worlds. Maybe it's an ancient Norse and Greek combined relic that only their combined skills can handle.
