As sturdy abhumans that can rival the strength and hardiness of space marines, it wasn't a surprise for the likes of [[Nurgle]] to take special notice. Originally created from the experiments on captive and rebel Ogryns from [[Vraks]] by a Nurgle warband known as [[The Tainted]]; Plague Ogryns are some of the newer and terrifying servants of Nurgle. Unlike the Berserker, Plague Ogyrns have been mutated to the point on non-recognition, resembling a miniature Great Unclean One or an ogryn-sized Nurgling more than the ogreish brutes they were based on.
As you can expect, these mutations have turned these stocky abhumans into near-invincible disease vectors, their huge bulk and natural hardiness allows them to host countless numbers of plagues and diseases to fester within their bodies. Due to this, getting so much as scraped by these things is a guaranteed one-way-ticket to a most painful end best not described.
After Vraks, its speculated by the Ordo Malleus that The Tainted have been further refining their creation of Plague Ogryns to be even more potent than they already are. Additionally, as the newest hip thing and having a live demo in Vraks: Nurgle warbands have been seeking out The Tainted for an opportunity to obtain these creatures, of course in exchange for slaves who have the unenviable role of being test subjects for The Tainted's experients.
