Helbrutes

A Helbrute is a variant of the Chaos Dreadnought that is a twisted mockery of the Space Marine Dreadnought he used to be, combining the firepower of a small main battle tank with the mind of a frenzied psychopath. Each Helbrute holds a living Heretic Astartes within its plated metal chest — a Chaos Space Marine driven over the edge of madness by the never-ending cycle of battle that defines the Long War. A Helbrute is piloted by a warrior who, like his Loyalist Dreadnought counterparts, has suffered extreme bodily damage in combat.
