As Gaunt, Stromm wore an armored life-support suit that arrested his body's decay, maintained his body's functions, and allowed him to walk; the suit also granted him superhuman strength (lifting 10 tons) and included a knockout gas dispenser. Stromm has employed many robots throughout his criminal career, including: An amorphous, super-strong robot with the ability to climb walls; a humanoid robot equipped with a destruction beam; the Robot-Master, a robotic duplicate of himself, equipped with his own brain engrams, as well as super-strength and destructive eyebeams; hovering, sharp-clawed robots; Willis, Daisy and Gary, three robotic children with malleable limbs, super-strength and heat Vision, respectively; and a variety of humanoid and non-humanoid robots equipped with energy weapons employed to defend Stromm's Vermont mansion. The android Robot-Master developed several unique robots of its own design, including tiny brain-borers; a bug-eyed "hovering holocaust" with a super-strong grip and a powerful blaster; a multi-tentacled sphere; and a conical, rocket-powered "sinister slinky."
