The Cranks

Lore & Background

The Cranks represent the tragic endpoint of the Flare virus infection within the post-apocalyptic world known as the Scorch. When a human contracts the pathogen, they progress through stages of fever and confusion before reaching Stage 3, where humanity is lost entirely. At this point, the infected become feral predators known as Cranks, possessing heightened aggression but no higher reasoning or memory. They are often found wandering in packs across the wasteland, wearing tattered remnants of clothing from their lives before the collapse. Their skin may appear decayed, and they exhibit a terrifying resilience to injury that makes them difficult to stop with conventional force. While WCKD claims to be working on a cure for the virus, many survivors believe the organization is responsible for spreading the infection in the first place.

Reader's Guide

The Cranks operate without a traditional hierarchy, functioning instead as a chaotic swarm driven by primal instinct. There is no leader or command structure among them; they simply exist to hunt and consume survivors of the Flare pandemic. Their stated goal does not exist in human terms, but their biological imperative is survival through predation. WCKD originally sought to study the virus to find a cure, inadvertently creating these monsters when subjects progressed beyond Stage 2 infection. While WCKD personnel sometimes wear protective gear to handle them, they view Cranks as failed experiments rather than people. The organization uses containment zones and fire to manage outbreaks in the Scorch. Resistance against the Cranks is purely reactive among survivors like Thomas and his group. They avoid open conflict whenever possible, relying on stealth and barricades during sandstorms or nightfall. There are no key leadership figures within the infected ranks, though WCKD agents occasionally hunt them for data. The only true control comes from immunity, which allows certain individuals to survive exposure without turning into a Crank themselves.
