The Sigma Armor was a set of power-enhancing armor created for the members of the Deadly Six by Dr. Eggman and Dr. Wily on the orders of Sigma-1. While it grants the Deadly Six greater strength, it was also equipped with technology that renders the wearers subservient to Sigma. (SU: #76, #77; WUB: MM, StH; MM: #50; SB: #9 StH: #274)
