Professor Utonium is the deuteragonist of the reboot series. He 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!


His personality in the 2016 series is a far cry from his original 1998 variant. While possessing the original's intelligence and love for his family, the 2016 Professor is far less intelligent and consistent in his depiction.

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.

He's frequently shown to be poor at parenting, often ignoring or blowing off the girls at points, and on some occasions being completely oblivious to issues that should otherwise be obvious.


Appearance-wise, the Professor is borderline identical to his original counterpart, the biggest physical difference being that nearly all of the sharp edges on the original have been rounded. Additionally, some more subtle alterations are his head shape, which is more consistent and slightly shorter than the original, his eyes, which are noticeably less expressive, ordinarily retaining their relaxed shape regardless of the Professor's emotional state, and his overall posture, which defies the original's heavily geometric shape.

Additionally, in flashbacks taking place before he created the PowerPuff Girls, he is seen with a slightly more stylish haircut, with a fringe at the front and a mullet-like tail in the back. Likewise, his hair in modern day is no longer strictly black, and has two grey streaks visible on his sideburns as well as the back of his head.

Like his original counterpart, he is also occasionally seen outside of his usual lab coat, most notable, he appears in nothing but swim trunks while in a manic episode in the episode "Painbow". Outside of his lab coat he appears even less geometric and more anatomically sound.

Ah, another stunning meal perfected by.. (he is interrupted by Blossom and cannot finish his sentence)

I've got sciencing to do.
