Usually beside Mayor, Ms. Bellum is his deputy and the "brains" of his operations. She has red hair, wears a red dress, red shoes, and her face is almost never shown throughout the series.
She is The Mayor's very competent assistant, a statuesque redhead. Ms. Bellum is a very beautiful, sexy, tall, shapely lady with a great deal of curly red/ginger hair and a red dress with red pumps and speaks with a throaty, alluring and quite unruffled voice.
She handles things the Mayor can't, which is practically everything. Her face is never shown onscreen, except for one instance in a form of a dog in Monkey See, Doggie Do, although The Powerpuff Girls Rule! briefly revealed part of it.
Whenever she appears, an object will either block her face or the camera will cut off everything above her neck.
Whenever she is the center of attention (as when Blossom's mind was switched to her body or when she fought Sedusa), her hair often covers her face. Other onscreen characters often claim that she is very pretty, with the exception of the abrasive Talking Dog.
In the bleak future of the episode Speed Demon, she expresses an obsessive attachment to the Mayor, possibly proving that she is in love with him, despite the fact he's married and then Professor of the episode The City of Clipsville.
She attended elementary school with the Professor and Ms. Keane and attended high school with Sedusa and Femme Fatale prior to the creation of the Powerpuff Girls
In Demashita! Powerpuff Girls Z, Ms. Bellum possesses blonde hair, a dark red dress (which is occasionally colored white), she has 2 gold bangles (one on each hand) and black high heel shoes.
Usually, Ms. Bellum covers her face with a tablet computer, which has lipstick imprinted on it. While the Mayor is different from his original counterpart and is more competent, Ms. Bellum in the anime still does most of the mayor's work for him in a manner similar to the original Ms. Bellum, and still appears to be the brains of the operation.
Also, Fuzzy Lumpkins is in love with her, and primary she is conquisted, however, she does not reciprocate his feelings, but later she hates Fuzzy. She is voiced by Youko Kawanami in the Japanese show and is voiced by Nicole Oliver in the English dub.
- Ms. Bellum's name and character could have came from the word "cerebellum," which is the part of the brain that controls motor control such as attention, language, and emotion. This theory could be true due to her being the "Logical" thinker in most situations and that she is the one who tells the mayor what he should do since he "lacks" said motor skills.
