Plague Marines are the fearsome and resilient warriors of the Death Guard, a Chaos Space Marine Legion dedicated to Nurgle, the Chaos God of decay, disease, and entropy. Once loyal Astartes, they were corrupted by the foul blessings of Nurgle, transforming them into grotesque and near-immortal warriors. Encased in corroded power armor that oozes with noxious filth, Plague Marines are walking vectors of contagion, spreading disease and rot wherever they tread.
On the battlefield, they are infamous for their resilience, shrugging off wounds that would fell lesser beings due to their bloated and corrupted physiology. Their weapons, often rusted and encrusted with pestilence, are carriers of deadly toxins and pathogens, ensuring that even a glancing blow can prove lethal to their foes. Plague Marines embody the horrific paradox of Nurgle’s “gifts,” thriving on the slow decay and despair they bring, turning every engagement into a nightmarish quagmire of sickness and death.
