Fan CastingPowerpuff Girls Z (Disney Channel dub)

Professor Utonium, his son, Ken Kitazawa, and his toy dog, Peach, are busy working on Chemical X, a powerful chemical substance in Tokyo City (New Townsville in the English dub), when Peach accidentally drops a daifuku into a vat of Chemical X, which magically transforms it into Chemical Z. Countries around the world suddenly experience weather calamity, and Ken uses a light beam ray attached to the vat of Chemical Z to blast Chemical Z on an iceberg in the Tokyo City bay, causing black-and-white rays of light to appear in the skies above it. Three ordinary 13-year-old girls, Momoko Akatsutsumi, Miyako Gōtokuji, and Kaoru Matsubara, are engulfed in white light, which transforms them into Hyper Blossom, Rolling Bubbles, and Powered Buttercup, the Powerpuff Girls Z. Peach is also engulfed in white light, transforming into a toy dog who can talk and call the girls to transform. Numerous rays of black light engulf people, animals, and objects to transform them into evil monsters who want to take over Tokyo City, such as Mojo Jojo, Fuzzy Lumpkins, Princess Himeko, Sedusa, the Gangreen Gang and the Amoeba Boys.
