Cradle Industries, sometimes called Cradle Technologies, was founded by inventor and self-made billionaire Ray Cradle, secretly the original Green Knight, shortly before he began his career as a costumed adventurer. His various patents-- in fields as diverse as communications, applied sciences, toys, and military hardware-- were the heart and soul of the company, which provided employment, both skilled and unskilled, to thousands of Jolt City residents.

Though its fortunes began to fall after Ray Cradle's death-- which some blame on the lackluster stewardship and reclusive personal life of his son, Anders Cradle-- Cradle Industries is still Jolt City's largest employer, land-owner, and tax-payer (with Proctor Products a steadily-rising second), making the city extremely dependent upon the company's well-being.
