A gigantic kaleidoscope in the CENTRAL CITY Museum turns into a fearful weapon at the hands of the colorful RAINBOW RAIDER. He uses the device to hypnotize the entire city, which is just his first step to controlling the whole world. The FLASH's super-speed is tested to the utmost. He must try racing at the speed of light to outrun the kaleidoscope's bewildering force. If he doesn't succeed, CENTRAL CITY could collapse into a newly created black hole!
