Carbon Costume

Melvin Sneedly (voiced by Jorge Diaz in the TV show and by Jordan Peele in the movie) is the central antagonist of the Captain Underpants series.  Melvin is incredibly smart, but is also a tattletale, which often puts him at odds with his fellow classmates, including Harold Hutchins.  There is some variation in Melvin’s costume, depending on which version you choose, but he always wears oversized glasses and a bow tie.

Professor Pippy Pee-Pee Poopypants, also known as Tippy Tinkletrowsers, is one of the main villains of the Captain Underpants series and movie along with Melvin Sneedly. He planned to solve the Earth’s hunger and trash problems but then he planned to shrink the entire planet for laughing at his silly name.
