Professor "Pippy P" Poopypants is the main antagonist of Captain Underpants and the Perilous Plot of Professor Poopypants by Dav Pilkey, the fourth book in Pilkey's Captain Underpants book series. A brilliant inventor and scientist hailing from the country of New Swissland (where it is tradition for everyone to have a silly name, hence the professor's name), he travels to the United States with the goal of using a pair of inventions of his to reduce the world's garbage supply and increase the world's food supply. However, on account of his ridiculous name, no one takes him seriously.

Angry Boss Codec

Angry Boss: Oh God, help me at once! Theres's a gargantuan robot on my building! Who is the brainiac in control of this mech?!

Owen That'd be Professor Pippy P. Poopypants.

AB: Seriously? Is that REALLY his name?

Owen: Yes. He is a scientist from the bizarre country of New Swissland, a combination of Switzerland and New Zealand. This country has a tradition for all of the citizens to have funny names, hence the Professor's name.

AB: So I take it no one can take him seriously because of his humorous name?

Owen: That's correct, Boss. In fact, he got so angry with people laughing at his name, that he became an evil genius, and his new ambition is to rule the world.


Owen: I just knew you were gonna say that. Anyway, the Professor has thad many attempts to rule the world, all of which were foiled by Captain Underpants.

AB: Interesting. Now excuse me while I kick this evil-doer out of my planet!
