Professor Utonium is the father and creator of the Powerpuff Girls. Known for his gentle ways and being much caring for his children. He is also an inventor and a scientist and has a huge merit of inventions in
his backpack. His interactions with the girls often include what one would think of as common events in a household with 3 children, such as telling them to eat their broccoli. His first appearance (although his appearance was different) was in the short Whoopass Stew.
The Ultimate Story[]
He was barely seen during the series, though he has been mentioned he's not only the father of the Powerpuff Girls, but also a very close friend with Professor Oak, as well as an Acolyte of the Mystics and related to the Great Wizard. However, he was seen as he was vacationing at Isle Delfino with his daughters, the Starfox Team, Misty, the W.O.O.H.P Spies, and Princess Peach.
