Named after Sir Isaac Newton, Newt is a tall, muscular boy with long blonde hair who operates as second in command in the Glade. Alby dies during the escape attempt by throwing himself onto a Griever.

He wishes to stay in the Glade and even tries to sabotage an escape plan by burning the maps drawn by the Runners. After being stung by a Griever, Alby undergoes the Changing and becomes convinced that they should not return to the outside world. Only a few Gladers, those who have been there the longest like Minho, ever see fit to question Alby's decisions.

The leader of the Gladers, Alby has authority over much of what goes on in the Glade. Soon after arriving in the Glade, Thomas makes both friends and enemies and proves a leader among the boys. Thomas proves to be brave, loyal, and clever, with isolated telepathic powers and a very limited memory of previous knowledge of the Maze. He only remembers his name and nothing else about his life. He arrives in the Glade with no knowledge of who he is or was.
