Horus Heresy - Mechanicum: Ursarax Cohort

Similar in design to Thallax, the Ursarax are not full-blown automata so much as a jumble of a living soldier’s important internal bits encased in a hard shell and strapped to a jetpack. These close combat specialists generally pack a pair of wicked lightning claws, though some are armed with power fists. They move at blazing speeds thanks to their Utan jump boosters.
