Ogryns

The Ogryn (Homo sapiens gigantus) are a huge and physically powerful Abhuman mutant subspecies of Humanity, often employed by the Imperium of Man as shock troopers in the Astra Militarum‘s Militarum Auxilla. Ogryns possess many traits prized by the Imperium; they are brutally strong and completely loyal, although extremely limited intellectually, which restricts their battlefield role to simple and direct assaults. They hail from a series of cold and barren planets across the galaxy that possess high gravity, such as Anark Zeta, which is why they appear larger, heavier and bulkier compared to baseline Humans.
