Morgan's perceived immunity in Fear the Walking Dead is attributed to a unique phenomenon: his near-death scent. This specific bodily odor, which develops after he experiences several severe and life-threatening encounters, effectively tricks walkers into believing he is one of them.
This distinctive scent acts as a natural camouflage, allowing Morgan to move among the undead largely unnoticed. The showrunner explained that Morgan's smell became so potent and similar to that of a walker that it confused the reanimated corpses, causing them to disregard him as a living threat.
- Mechanism of the "Immunity":
- Physiological Response: After significant physical trauma and brushes with death, Morgan's body produces a unique scent.
- Walker Deception: Walkers, relying heavily on their sense of smell to differentiate between the living and the dead, are fooled by this particular odor.
- Stealth Advantage: This allows Morgan to blend in with hordes, reducing the risk of direct attacks and giving him an unusual tactical advantage in post-apocalyptic survival.
This isn't a true biological immunity to the virus or bites, but rather an olfactory illusion that protects him from being targeted by walkers. It's a unique survival adaptation resulting from his intense experiences.
