The spirits of the maze itself could turn against Percy. They could be angry at all the demigods who have been trespassing for years and decide to stop Percy from getting through by any means necessary.
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.
One common theme is the characters from the two series teaming up. For example, Percy and Thomas might join forces to face a common enemy. Another theme is the exploration of different worlds. Since Percy's world is full of Greek mythology and the Maze Runner world is post - apocalyptic, fanfics often play with the idea of how these different settings interact. Survival is also a big theme, as both series have elements of characters fighting for their lives.

One idea could be Percy discovers a hidden section of the maze that leads to an ancient Greek library filled with forgotten knowledge. This knowledge could help him in his future quests.
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.
Yes, there are likely many fanfictions out there that focus on their adventures in the maze without any inappropriate content. Fanfiction writers often explore the relationships, character growth, and the challenges they face in a more family - friendly way.
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.
Percy and Thomas are often popular to pair. Percy's heroic and sometimes reckless nature combined with Thomas's leadership and determination can create an interesting dynamic. They can learn from each other's strengths and weaknesses.
There is a fanfic called 'The Maze Trials of Percy and Rachel'. In this story, it really explores the different trials they face in the maze. It's interesting because it not only has the action of fighting monsters but also shows their character development. Also, 'Rachel Dare's Maze Encounter' is a great one. It shows Rachel's courage as she faces the unknown in the maze along with Percy, and how their bond grows stronger.
