Zero the Silent

Origin
Zero the Silent, the human fly, was a British masked mystery man. He was a disgraced Scotland Yard detective who invented a highly advanced costume intending to become a cat burglar as vengeance but changed his mind when policeman after policeman were being killed by the Rattlers, a gang from Chicago terrorizing London.

The costume was black rubber with "suction discs" on the hands and knees, allowing him to crawl along walls and ceilings. Attached to his wrist was a rubber throwing ball with a lead core on an elastic cord; Zero bowled googlies at his opponents, with the elastic bringing the ball back to him.

Trivia

 * His skin-tight get-up predated that of the Phantom and Superman's and it's suggested that the author intended his mask to cover his entire face but soon changed it to a cowl to fit the illustrations.
 * He had a fox terrier named Mickey who did not sit on the side-lines.
