The shadow stormtroopers, also known as Blackhole stormtroopers due to their association with Agent Blackhole, were specialized Imperial stormtroopers.

Their most distinguishing feature was their all-black armor—a stark contrast to the typical white armor common to other stormtroopers. This unique black armor provided some stealth benefits, which resulted from the stygian-triprismatic polymer material used in the production of the armor. Lord Blackhole also incorporated meltmassif into his shadow stormtroopers for use when he would disable them. Shadow stormtroopers also carried cloaking devices that rendered them invisible, or at the very least enter a state close to such, for a short period of time by warping the light around them.
