When he created his costume, Abner Krill possessed advanced technology in the form of the costume's polka dots, which were controlled through the costume's belt. When attached to his costume, they were inert, but once removed, they would enlarge in size and become various different devices which could aid in his crime sprees, most notably a flying saucer which he used as a getaway vehicle.
Gimmicked dots used by the Polka-Dot Man included:
Flying Buzzsaw Dot, a red polka dot designed as a projectile. The dot had a rotating interior mechanism upon which a circular saw blade was mounted.
Flying Saucer Dot, a yellow polka dot which expanded rapidly into a flat, man-sized glider. It was steered by a series of buttons or switches on the Polka-Dot Man's belt.
Sun Dot, a gold polka dot designed as a projectile. It was gimmicked to resemble a model of the sun and emitted a blinding, disorienting light similar to a flare.
Bubble Dot, a white polka dot which expanded into a translucent capsule capable of flight. Like the Flying Saucer Dot, it was steered by a belt apparatus.
Fist Dots were red, yellow, and orange polka dots designed as projectiles. They were thrown at once and gimmicked to resemble human fists. When bounced off opponents at close range and in concert, these dots could produce concussive effects.
Hole Dot, a black polka dot simply referred to as a "hole" by the Polka-Dot Man. It opened up what appeared to be a teleportation transport system and was presumably developed with assistance from General Immortus.
^so I guess he's like Green Lantern, but polka dots? lol
