The main characteristics of these 'onyx troopers' included inbuilt shields that were even stronger than that of old droidekas, heavy plasma weaporny, missile launchers, seismic generators, density projectors, and shrapnel launchers. They were also larger and more streamlined than their dark trooper predecessors. The final versions of these exosuits were to be moderately expensive, as this equipment was deliberately made low-quality. Only one proper version of the onyx trooper exosuit was ever made, and it was never used in combat.
