Abner Krill, also known as Polka Dot Man or Mister Polka-Dot was a bizarre DC villain who faced off against Batman and Robin.
Abner Krill decided, for reasons unknown, to launch a crime wave based on spots and dots in Gotham City, where he inevitably came into conflict with Batman and Robin, the city's masked protectors. As the fearsome Mister Polka-Dot, he wore a bizarre costume covered in spots, the point of which soon became apparent - once removed from the costume, the spots could be used for a variety of purposes, creating deadly weapons and a bizarre escape vehicle. Perhaps surprisingly, he succeeded in capturing Robin, but Batman was nonetheless able to save his crime fighting partner and bring Krill's crime spree to an end. He returned some years later, undaunted, yet also lacking his gimmicks, with the spots on his costume merely decorative. Using a baseball bat, he assaulted Officer Foley of the Gotham City Police Department, causing him very minor injuries. He was then beaten badly by Harvey Bullock, who was sick of costumed villains in the city. The assault put the Polka Dot Man (as he now styled himself) in traction, and he filed a brutality suit against the police department which resulted in Bullock being forced to see a psychiatrist for some time.
He later worked with General Immortus and Professor Milo, sporting a new costume and calling himself Mr. Polka Dot again. He like many other unpowered villains were given powers by Milo and Immortus and did jobs for them. However they were all killed by Human Flame.
Powers and Abilities
Whether he created the suit or stole the technology is unknown, but Abner Krill possessed advanced technology in the form of his costume's dots. 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 spree, most notably a flying saucer which he used as a getaway vehicle. The spots were controlled through the costume's belt.
Batman the Brave and the Bold
Polka-Dot Man made cameos in the episodes Legends of the Dark Mite, A Bat Divided, and Joker the Vile and the Villainess.
