Professor Antonio Utonium is the scientist responsible for creating the Powerpuff Girls. He is very "square" and old-fashioned. He 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 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 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, and easily manipulated, but still retains his caring father figure image. His catchphrase is "I made it!". He is fiercely protective of the girls, sometimes to a fault. He is a very affectionate and supportive father whose pep talks often bring the girls around when they are discouraged. While he is sometimes portrayed as rather skittish, he can be firm with the girls when he needs to. He is a keen golfer. His most successful inventions are those that he makes by accident. 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. He is also unlucky in love, examples including his previous relationships with Sedusa and Ms. Keane. Sedusa betrayed him by trying to enter the family circle so that she can punish the Powerpuff Girls so that they won't be able to stop her crime sprees. Ms. Keane didn't like Professor Utonium's dislike for cats, which is because he had "a bad experience with one."
