Gally is an antagonist because he believes that Thomas is an enemy of the Glade, had proposed him as a traitor of the Gladers, and attempted to kill Thomas, accidently killing Chuck in the process. As a Keeper, one of the leaders of the Glade, and Thomas’s enemy, Gally is a major character in The Maze Runner. Gally never liked Thomas from the beginning of the book and had been very negative towards all other Gladers, with little change to grow to hate Thomas. This would make him a closer to a static character.
