Minho

"It's kind of hard to ask a dead guy what he did wrong."

— Minho

In The Maze Runner, when Minho first appears, he is found by Thomas laying on the ground from exhaustion as he'd just gotten back to the Homestead from the Maze. Thomas calls for Alby and is directed by Minho to get him water. Alby telling Thomas that Minho is the only one who can boss around him like that. After Alby brings the water, Minho explains that he found a dead griever. The next day, Alby and Minho go into the Maze to find the dead griever, but, when Alby touches the griever, it springs to life and stings him. Minho has to carry Alby back to the other Gladers for help, but after the doors start closing everyone knows it is too late for them. Thomas jumps to the rescue a second before the doors close. Minho runs in panic, but Thomas, being the new guy, thinks there is hope. He climbs the wall and drags Alby with him. After a griever starts following them, Thomas flees, leaving Alby behind, then Thomas somehow fools the grievers which Minho sees. Minho grabs Thomas and together they trick the grievers over the Cliff. Then, the Gladers wake up to find that the three are still alive and have a Gathering to decide what is to be done with Thomas. Minho shows up at the Gathering, which confirms that he is the Keeper of Runners. Thomas is first elected as Keeper of the Runner by Minho, but becomes just a runner. Minho teaches him everything he needs to know. Later, he supports Thomas's plan to escape from the Maze by going through the griever hole.
