Villains and Monsters

Main article: List of villains and monsters in Demashita! Powerpuff Girls Z

Most of the villains of Demashita! Powerpuff Girls Z were normal, everyday humans/animals/organisms/objects, until the explosion of the chemical Z ray and the effect of the black lights (or Him's black particles,) transformed them into "Monsters." The black light is drawn to people, animals, organisms or inanimate objects that were dominated by negative emotions and not only affects the appearance of its victims and grants them powers, but it magnifies their desires and removes their moral inhibitions. In the more recent episodes, Him (Kare) can also inflict darkness in the same way as the black lights with a black demon powder, creating monsters in the process. Whenever these villains cause trouble, the Powerpuff Girls Z must apprehend them and, for the most part, turn them over to Professor to be restored to their normal form with the Chemical Z Ray. At other times, when the trouble surrounding the darkness is vanquished, the black spores will not usually go away on their own. In Episode 20, Mojo creates the Rowdyruff Boys, similar to the ones in the original show, but older.
