Tom Kenny played both the narrator and the Mayor in the original The Powerpuff Girls series.
Kenny’s narration helps establish the show’s storybook-like presentation, while his performance as the Mayor supplies one of the series’ most energetic comic voices. The two roles are distinct: the narrator speaks from outside the story, whereas the Mayor is a character living in Townsville.
This double casting is easy to overlook because the voices sound very different. The Mayor is high-pitched, excitable, and often anxious, while the narrator is more measured and descriptive.
Tom Kenny’s other major animation work includes SpongeBob SquarePants, but that role is unrelated to his work on The Powerpuff Girls. Tom Kane, another actor associated with the franchise, voiced Professor Utonium and HIM instead.
