Sara Bellum is the mayor’s secretary in the original series The Powerpuff Girls.
She works in Townsville City Hall and is frequently shown managing the Mayor’s affairs. Although the Mayor holds the official title, Sara is often portrayed as the more organized and capable person in the office.
Sara Bellum is recognizable for her red hair, professional clothing, and the fact that her face is usually hidden from the audience. The series treats that visual choice as a recurring joke rather than making her identity a mystery.
Her name is sometimes confused with the Mayor’s title or with Ms. Keane, the girls’ teacher. Ms. Keane belongs to the school setting, while Sara Bellum is connected to City Hall and the Mayor.
