Professor Utonium (voiced by Tom Kane) is a scientist who works in his home in the suburbs of the City of Townsville, and the Powerpuff Girls’ creator and father. A stereotypical scientist, his general attire is a white lab coat and black pants. The Professor once housed a chimpanzee named Jojo (later to become Mojo Jojo) as a lab assistant who proved to be reckless and destructive. While the Professor was stirring his perfect girl concoction, Jojo shoved him, causing him to accidentally break a flask containing the mysterious “Chemical X” which spilled into the formula, thus creating the Powerpuff Girls. The Professor is a genius in many fields of science, having shown knowledge in fields such as physics, chemistry, and biology as well as being a skilled inventor. Aside from his role as a scientist, he acts as a parent to the Powerpuff Girls. Although he apparently did not legally “adopt” the girls, everyone who addresses him calls him “their father” and they as “his daughters”. The Professor can be strict, easily manipulated and overprotective at times, but still retains his caring fatherly image. In the episode “Keen for Keane”, the girls set up Professor Utonium and their kindergarten teacher Ms. Keane on a date for Valentine’s Day, resulting in the two temporarily becoming an item.
