But look at me--I went toe-to-toe with the Batman. That's who I am.
~ Mister Polka Dot.
Abner Krill, also known as Polka Dot Man or Mister Polka-Dot is a bizarre supervillain in the DC Comics universe and is an enemy of Batman, Robin, Nightwing, and Batgirl.
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 later battled Nightwing and Batgirl but was defeated.
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 became a member of a group of second-rate villains that worked for General Immortus. Immortus, with the help of Professor Milo, upgraded the villains powers and gadgets. The group was undone when they were betrayed by Human Flame. Most were killed in the brutal battle, including Mister Polka-Dot. His head was squished after a manhole cover landed on him during the battle against Human Flame and Seductress.
