Designed to operate in the most lethal and hazardous theatres of war, the Thallaxii have undergone extensive cybernetic augmentation, allowing them to wield extremely potent weaponry with inhuman accuracy. Created exclusively by the Ordo Reductor for the other militant arms of the Mechanicum, what little organic material remains of the Thallaxii is protected and enhanced by the Lorica Thallax. This encases their major organs, nervous system and cerebrum, their skeleton and limbs being entirely replaced with armoured mechanical systems powered by an internal reactor core. Their primary weapon is the lightning gun, which is just as effective at killing the living as it is at overloading vehicles and weapons.
When engaging with more heavily armoured targets such as vehicles or fortifications, the Thallaxii will be rearmed with the devastating multi-melta, the furious blast of heat it produces turning an enemy’s sanctuary into little more than bubbling slag.
The Lorica encloses the major organs, nervous system and cerebrum, but entirely replaces the skeletal structure and limbs with armoured bionics powered by an internal reactor-core. Surgical excision of the subject’s pain sensors, emotions, and normal human sensory apparatus and the agony caused by the Lorica’s implantation, leaves the Thallax a cold, calculating killing machine (albeit one that retains a degree of independent thought).
