The Crystal Queen was a crime boss with dreams of world conquest. She stole the legendary Blue Crystal which could be commanded to emit a deadly ray, which turned a person's skin blue as they died or could demolish inannimate objects with explosive force. She was defeated by Invisible Hood who was immune to the ray, thanks to his invisibility. The Crystal Queen was brazen and had a good amount of resources, including a fortress and speedboats. She usually carried a handgun.
