In a Maze Runner - Harry Potter fanfiction crossover, the creatures from the Maze could have some connection to the magical creatures in Harry Potter. For instance, the Grievers could be magically enhanced versions of some dark magical creatures. The characters from both universes would have to work together to either defeat or control these dangerous entities. The Gladers' knowledge of the Maze and the Hogwarts students' knowledge of magic would be crucial in this situation.
One interesting crossover could be the characters from Maze Runner finding themselves in the wizarding world of Harry Potter. They might be amazed by the magic and spells, while the Hogwarts students could be intrigued by the Gladers' survival skills. For example, Thomas could befriend Harry and they could team up to solve a mystery that involves both the Maze and the Dark Arts.
A crossover could involve the Maze Runner's concept of a post - apocalyptic world with the magical elements of Harry Potter. Maybe the Maze was created by a dark wizard in an attempt to control a group of people. The Gladers could use some of the magical items from the wizarding world to escape the Maze. Like, using a Portkey to get out of a particularly difficult section of the Maze.
One interesting crossover could be the magical elements of Harry Potter in the post - apocalyptic setting of Maze Runner. For example, using spells to solve the maze puzzles. Another could be the characters from both universes teaming up. Like Harry and his friends joining forces with Thomas and the Gladers to fight a common enemy, perhaps a new dark wizard who has also influenced the Maze Runner world.
One interesting crossover could be the characters from 'Percy Jackson' using their powers to navigate the maze in 'The Maze Runner'. For example, Percy could use his water - controlling abilities to create paths or solve water - related puzzles in the maze. Another could be the Gladers from 'The Maze Runner' learning about the Greek mythology in 'Percy Jackson'. They might be amazed at the existence of gods and demigods.
A really cool crossover concept is when the Maze itself appears in the Percy Jackson universe. The demigods have to figure out how to navigate it while also dealing with the Grievers. Meanwhile, the Gladers are trying to adapt to the presence of gods and monsters that they've never encountered before.
In some fanfics, a plot twist could be that Voldemort teams up with the Creators from Maze Runner. This completely changes the power dynamics as the combined evil forces pose a huge threat to the protagonists. It makes for a very intense read as the heroes have to find new ways to fight back.
Another idea is that the Death Eaters in Harry Potter create a new kind of maze similar to the one in the Maze Runner as a form of torture or experiment. Harry and his friends then team up with the Gladers to escape this new, magical maze.
One idea could be exploring the backstories of the characters more in - depth. For example, what was Thomas' life like before he entered the maze? Another idea is to create an alternate ending where the Gladers find a different way to escape the maze and deal with the outside world. You could also write a fanfiction about a new group of people who enter the maze after the events of the original story and how they interact with the remaining elements of the maze and any surviving Gladers.
One great Harry Potter Maze Runner fanfiction is 'The Crossover Quest'. It combines the magical world of Harry Potter with the post - apocalyptic setting of Maze Runner in a really interesting way. The characters from both universes interact in unexpected ways, like Hermione using her intelligence to solve the maze puzzles.
The idea of a group working together against a common enemy, which is prominent in Maze Runner, can be added to Harry Potter fanfiction. The Hogwarts houses could form an alliance similar to the Gladers. They could fight against a new dark force that is trying to take over the wizarding world. Each house could bring their unique skills, just as the Gladers had different roles in the Maze.
One idea could be exploring the backstory of the girl character before she entered the Maze. Maybe she had a special talent or a hidden past that no one in the Glade knew about. For example, she could have been a trained fighter in a secret society outside the Maze world.
A cool plot for the maze runner fanfiction could be that there is a traitor among the Gladers who is secretly working for the people who put them in the maze. This traitor could be slowly sabotaging their efforts to escape. Or perhaps the maze starts to change in really strange and unpredictable ways, like the walls start moving at random times instead of just at night. The Gladers then have to figure out a new strategy to deal with this. And what if there were other groups of kids in different mazes and they somehow find a way to communicate and team up to escape all the mazes together.
