Teresa could also be a likely one. She has a special connection to the whole situation, being part of the experiment in a different way. She might time travel to understand more about her own role and to try to make amends for some of the things she did under the control of WICKED. She could go back to change how she interacted with Thomas and the others in the early days, hoping to create a better outcome for everyone.
Newt might be an unexpected but interesting choice. He is a very empathetic character. He might time travel to a point before he got infected. He could try to prevent the spread of the Flare in the Glade. He would do this not just for himself but for his friends, as he has seen the horror that the Flare can bring. His selfless nature would make him use time travel to protect those he cares about.
Midoriya would be a likely candidate. He's always looking for ways to improve and become a better hero. Time travel could give him the chance to learn from past heroes directly, like All Might in his prime. He could also go back to understand more about One for All's past users and how to master the quirk faster.
Eleven could be a likely candidate. Given her powerful psychic abilities, she might accidentally or purposefully time travel. Her powers have always been a bit unpredictable, and time travel could be an extension of that. She has a strong connection to the Upside Down, so she might be sent back in time to learn more about its origin or how to stop it.
His character would develop a sense of fatalism. If he travels through time and realizes that some events are inevitable no matter what he does, he might become a bit more resigned. However, at the same time, he could also become more determined to fight against the things that he can change. For instance, if he sees that the Maze is always going to be a difficult place, he might focus more on getting the Gladers out rather than trying to change the Maze itself. He'd be constantly weighing what he can and can't change, which would shape his character in complex ways.
Sasuke could be a fascinating character to focus on. His brooding and powerful nature would create an interesting contrast in the Maze Runner world. He could use his sharingan to gain an edge in the maze, seeing things that others can't. And his complex personality, with his thirst for power and his loyalty to Naruto (in some ways), would add depth to the story. He might initially be at odds with the Gladers but then come to respect them as he realizes their own forms of strength.
Annabeth Chase would be an exciting character to center on. Her intelligence and strategic thinking would be a great asset in the maze. She could quickly analyze the layout of the maze and come up with plans. She might also be the one to bridge the gap between the two groups, as she's good at understanding different people and situations. Her knowledge of architecture and mazes from her own world could be applied to solving the mysteries of the Maze Runner's maze. And her relationship with Percy would add an extra layer of drama, especially when dealing with the new and dangerous situations in the crossover world.
The Gladers might be interested in reading The Maze Runner fanfiction because it offers a new form of engagement with their world. In the maze, their lives are full of danger and mystery. Reading fanfiction could be like exploring side alleys of their own story. They could find comfort in seeing their own struggles and triumphs retold in different ways. It might also be a way for them to feel less alone, as if there are others out there who understand their complex situation, even if those others are just fictional creators of the fanfiction.
Thomas is definitely a popular character to focus on. He's the main protagonist, so there are a lot of ways to develop his character further. His leadership skills, his relationship with Teresa, and his determination to escape the maze are all aspects that can be explored. Newt is also very popular. His kind - hearted nature and his role as a sort of second - in - command in the Glade make him an interesting character to write about. And of course, Teresa, as she has a complex relationship with Thomas and her own secrets related to the maze.
I think Fundy would be likely to time travel. He has a complex relationship with his family and the SMP. Time travel could be a means for him to understand his father better or change the way his family relationships developed. GeorgeNotFound could also be a candidate. He's often in the background but has a strong connection to Dream. Time travel might be his way of getting more involved in the SMP's events and helping Dream in a different way. Lastly, Niki could be a time traveler. She has been through a lot of changes on the SMP, and time travel could be her opportunity to go back and make the SMP a more inclusive and friendly place from the start, especially for those who have been marginalized.
I think Yamato could be a good choice too. His ability to control wood style could be really useful in the past. Maybe he could time - travel to help with the growth of the first trees in the ninja world or something like that. And his calm and collected nature would help him adapt to the new situation in the past.
I think Izuku Midoriya would be really interesting. He's the main character and has so much knowledge about the heroes and villains. If he time - travels, he could use his understanding of quirks and combat strategies to change the past or future in significant ways. For example, he could go back and give advice to All Might when he was younger, which might change how All Might deals with villains later on.
