Humans infected by disease. They live in the remains of the world, seeking people when they approach. Some Cranks are farther gone than others. Cranks get crazier the farther gone they are. Eventually the disease kills them, but that takes a pretty long time. Some Cranks that aren't crazy at all, yet they ARE Cranks by name and are infected. This character was inspired by The Maze Runner and the second book The Scorch Trials. Both of those books were written by James Dashner.
