Professor Jonathan Utonium is the father and creator of the Powerpuff Girls. He appears in the later chapter of the comic. He originated from the Cartoon Network series The Powerpuff Girls.


Professor Utonium first brought the girls to their new school in Megaville. After that he wasn't seen until after the battle between Dexter and Mandark when they went home to rest.

When Buttercup came home with a letter from Jack for her father saying that he had to speak with him because Buttercup was gone wild at the School Dojo with Kendo class. The professor and Jack decided that Courage had to stay with Buttercup to take notes of what she was doing. Later when he came home he said to Buttercup that she must do something besides materials arts. He first suggested science, but that didn't work out so they went with cooking which worked out great.

Before the science fair Nora Wakeman and Jenny visited, despite her grounding he said to Buttercup that she could go to the science fair and sell special snacks along with Jack.

He was one of the many scientist that was attending the science fair where he was one of the bystanders who witnessed the infiltration of the Cluster. He quickly escaped along with Nora underneath the building where he and the other scientists were trying to open the door to the safe room. The power shut down and needed muscle to open the door, luckily Bubbles was there to provide, the Professor showed Bubbles The Central Megaville Skyway Hangar's past weaponry including Dynamo. He told Bubbles to let the people in the safe room past the equipment. The Professor was seen activating Dynamo to help Bubbles close the door. When the Cluster monster started to infect Dynamo with a virus he then had to shut her down for a cold reboot. After noticing that the bomb went off he checks with Dexter about if there's a possible way to escape from the explosion, but he said there isn't. Having thought that he and everybody are never again going to see the light of day, Otto appears before him and is trying to tell him that the explosion is probably just a stop-gap. Otto also tries to tell Utonium that he and the other scientists must break it, but Utonium doesn't fully understand what Otto meant. The bomb went off and he was engulfed alongside the others in the explosion.

Following the explosion, Utonium sees everyone is still alive and boards Dynamo to get back to the stage of the science fair. There he reunites with his girls and encounters the Rowdyruff Boys again. Boomer goes around kissing every girl to everyone's surprise. Weasel announced he will enroll as a teacher in Megaville Elementary so he and the other scientists can make use of Dexter's facilities inside of the school to figure out what happened.

A few days later Utonium picks his girls up from Dexter's house while he was at work. The following day he and the girls head to the school for a meeting with all the scientists in order to figure out what the bomb did. The girls were there because of their superhero input. Through discussion they eventually figured out that Earth's space and time is slowing down and that the planet is being isolated from the rest of the galaxy. After Admiral DeGill contacts them, he requests the girls and Jenny to come to the Justice League International Watchtower. Utonium stays behind with the other scientists to continue finding a solution.


Professor Utonium wears a white lab coat, with pens in its pocket, and wears a shirt and tie, and his head is impossibly rectangular with carefully parted black hair and thick eyebrows. The Professor's voice is deep and thoughtful, exactly the sort you might expect form am eminent scientist and/or a father figure in a 1950s TV show.

Powers and Abilities

He is a keen golfer. His most successful inventions are those that he makes by accident - such as the Powerpuff Girls themselves, or the containment device seen in "Bubble Boy" (he says of it: "Once again, I have no idea what I did!"). Most inventions he creates on purpose usually don't work or have some great flaw. This extends to his cooking skills as well, the chilli he made for the Townsville cookoff one year resulted in a hazmat team bordering off the house.


Professor Utonium (voiced by Tom Kane) is a brilliant scientist who works in his home in the suburbs of Townsville. A stereotypical scientist, his general attire is a white lab coat and black pants with pens tucked into the lab coat's breast pocket. The Professor once housed a chimpanzee named Jojo (later to become the girls' arch-enemy, Mojo Jojo) as a lab assistant who proved to be reckless and destructive. Jojo pushed the Professor while he was stirring his Perfect Girl concoction, causing him to accidentally break through a glass 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 (inventing things such as a giant bipedal Powerpuff robot called the DyNaMo and a super suit that allowed him to fight crime with the girls). Aside from his role as a scientist, he acts as parent in The Powerpuff Girls' lives (doing things a father would normally perform, like preparing their school lunches or cheering up his "daughters" when they've been hurt). Although the girls address him as "Professor", when discussing the Prof with others, they refer to him as "our dad". The Professor can be odd, silly, clumsy, easily manipulated and over-protective at times, but still retains his caring father figure image. His catchphrase is "I made It!" which is seen in such episodes and specials "Uh Oh Dynamo" and "Powerpuff Girls Rule". In the initial seasons The Professor was seen with a tobacco pipe which was later dropped. In the episode "Town and Out", he pretended to like Citysville, and admitted he hated it when the girls told him that they did.


  • Officially, Utonium's first name is Antonio.
  • Professor Utonium has the same cup as Dr. X with the text World's Best Dad of All Time.
  • In Griddles stories his first name is Adric.
