Thomas, from “The Maze Runner,” is a somewhat naive, but intelligent and curious individual. To be fair, most anyone would be naive in his situation—stripped of his memories and placed into a mysterious glade in the center of a maze with other adolescent boys.
Thomas, however, is defined by his courage and his upright nature, as well as his intellect and curiosity. He is always willing to stick up for other boys in the group, and he willingly goes into the maze to help find and save another boy from the vicious creatures that reside there.
He is also a willing and capable leader, around whom the other boys rally and to whom they look to for guidance. His courage and care for the others make him a very good leader.
