Plague Marines are the festering, disease-ridden warriors of the Death Guard, servants of Nurgle, the Chaos God of decay and pestilence. Once noble Space Marines, these warriors were forever changed during the Horus Heresy when their Primarch, Mortarion, and the Legion embraced the corrupting influence of Nurgle. Their bodies have become bloated, swollen with rot, yet their resilience is unparalleled. Encased in power armor that has fused with their diseased flesh, Plague Marines are walking symbols of entropy, carrying with them the horrific gifts of Nurgle: disease, rot, and endless decay. Each wound they sustain only serves to spread Nurgle’s blessings further, as their bodies become walking vectors of infection.
On the battlefield, Plague Marines are relentless, marching slowly but unstoppably into enemy lines. Armed with bolters, plague knives, and foul, corrupted weapons like the Plague Spewer or Blight Grenades, they spread pestilence with every strike. Their resilience, boosted by Nurgle’s blessings, makes them nearly impossible to kill, shrugging off injuries that would fell ordinary warriors. Their tactics center around overwhelming their foes with unrelenting assaults and choking the battlefield in filth and disease. As they fight, they cackle in twisted joy, reveling in the endless cycle of death and rebirth that Nurgle represents. Wherever they go, life withers, metal rusts, and the very air becomes thick with the stench of rot and decay.
