Professor Utonium

"You have my thanks."

Professor Antonio Utonium is the scientist responsible for creating the Powerpuff Girls. He is very "square" and old-fashioned. He stands 6' 1" and weighs 137 lbs. He is fiercely protective of the girls. 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 (particularly when they get into physical fights).
