During the non-events of Robotnik Reigns Supreme, Oscar the Pig was granted his own personal Death Squad to hunt down and eliminate any undesirable elements in Robotnik's dominion. Death Squad Troopers looked distinctly different from standard Troopers, with no faces (except for two red optic slits) and being covered head to toe with jet black armour. They were armed with plasma rifles and riot staffs.
When Oscar and his Death Squad encountered Sonic the Hedgehog, they had no records of his existence and attempted to capture him. Though they looked more intimidating than normal Troopers, the Death Squad robots were just as inept at fighting Sonic, who destroyed them all in a second.
