Professor Utonium

Professor Utonium''' is the scientist responsible for creating The Powerpuff Girls thus becoming their father and legal guardian. He is fairly close to his original 1998 series counterpart, but with some rather noteworthy differences.'''

Brainy Professor Utonium accidentally created The Powerpuff Girls when he added Chemical X to sugar, spice and everything nice. He is a gentle and doting father figure to them.

Professor Utonium is very proud of his three little superheroes, but he worries about them a lot. Sometimes, he has to give the girls his Patented Trust Talks, teaching them life lessons about choosing friends wisely, obeying rules and not giving in to peer pressure. What a guy!

Personality
In the place of naiveté of the original, the Professor is very goal-oriented to the point of being negligent and even shallow at points. This can clearly be seen with the backstory of Blisstina, where his reason for creating a girl was purely for the sake of competing with a female colleague, his parental instinct only manifesting after Bliss's creation. It can also be seen with Donnie, where, rather than rationally study the problem to see if he could find a solution, the Professor simply has Donnie sign a waver that voided him from being responsible for any potential misfortune brought upon Donnie.
