Straight-laced Prof. Utonium attempts to create perfect little girls, but he accidentally includes "Chemical X." This results in the creation of Blossom, a take-charge red-head; Bubbles, a blonde sweety-pie; abd Buttercup, the ready-to-fight brunette. These flying, super-strong, karate-chopping girls have and use their occasional heat vision. The girls race into action to save their city of Townsville, not to mention the world, from all sorts of crimes and creatures.
