A great idea for a Maze Runner fanfic would be to focus on the creatures in the Maze. What if there was a way to communicate with them? You could write a story about a Glader who tries to make peace with the Grievers instead of fighting them. Another option is to write a fanfic that takes place after the events of the books or movies. How do the survivors build a new society? What challenges do they face? And how do their past experiences in the Maze shape their new world?
An OC who is a natural leader but has a very different leadership style from Alby. Instead of strict rules, they focus more on building a community based on trust and friendship. This could cause some initial conflict as the Gladers are used to Alby's way, but in the long run, it could lead to new solutions for escaping the 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.
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.
One idea could be that Naruto and the other ninjas are trapped in the Maze Runner world. Naruto uses his shadow clones to explore different parts of the maze. They could encounter new types of creatures that are a mix of Naruto's world and the Maze Runner world. For example, some sort of beast with both the characteristics of a Nine - Tailed Fox and a Griever.
Well, perhaps some of the Gladers accidentally get sent back in time to when the Creators were still planning the Maze. They could then try to sabotage the plans from the inside. They might steal the blueprints of the Maze, or change the types of creatures that are supposed to be put in the Maze. This would completely change the dynamic of the original story and create a whole new set of challenges and adventures for them.
Well, perhaps a crossover where the Volturi from Twilight are intrigued by the experiment of the Maze Runner world. They might see it as a new form of control over a large group of humans. Meanwhile, Thomas from the Maze Runner could have some sort of special connection with a Twilight character, like Bella, and they work together to break free from both the Maze and the Volturi's potential threat.
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.
One interesting 'Maze Runner' and 'Lemon' fanfiction could be one where the characters are in a new situation within the Maze but with a 'lemon' - themed twist, like finding lemon - scented plants that have some special power in the Maze. Another might involve the characters having a lemonade - making competition during a break in the Runner's activities as a form of relaxation.
One interesting plot idea could be a 'what if' scenario. What if Thomas and Newt got separated from the group early on in the maze? They would have to rely solely on each other for survival. Newt's knowledge of the Glade and Thomas's determination could create a really intense dynamic as they try to find their way back. They might face new and unknown threats in the maze that the others in the group haven't encountered yet.
One plot idea could be that Thomas and Teresa discover a hidden part of the maze that has a lemon tree. They realize the lemons have special properties that could help them escape. Another could be that in a memory wipe gone wrong, Teresa starts to remember a past life related to lemons and it holds the key to a mystery in the maze. Maybe they use lemons to create a signal that attracts the Creators' attention but in a way that they can bargain for their freedom.
