# 5 Hidden Captain Underpants Characters You Never Knew Existed! Captain Underpants, the wildly popular absurdist comic and animated series created by Dav Pilkey, is beloved for its hilarious protagonist, Junior, and his comedic escapades. While most fans know Junior, George Beard, and the legendary Underpants, fewer know about the rich array of secondary characters lurking behind the scenes. These lesser-known figures add layers of humor, depth, and nostalgia to the franchise—some even play subtle but pivotal roles. Here are five hidden Captain Underpants characters you’ve probably never heard about! ## 1. The Secret Scientist (aka “Madcap”)
Deep in the lab of Junior’s undercover school hideout, you’ll find The Secret Scientist, a quirky character with wild hair, oversized goggles, and a name that hints at both madness and brilliance. While rarely seen in full scenes, this unnamed genius designs gadgets like rubber-ribbed Underpants That Shoot Puns and a Breakroom Disguise Suit. His invention of “Underpants of Invisibility (Sort Of)” powers numerous Underpants-esque mishaps. Though overshadowed by Junior, The Secret Scientist embodies the show’s love for brainy, if awkward, invention. ## 2. Principal Powresh Salesman
When Captain Underpants sneaks into Ronald’s classroom to cause a little chaos, he passes by Principal Powresh, a mustachioed school official whose alias doubles as a nickname. Though technically just a minor authority figure, Principal Powresh often thwarts Junior’s schemes with over-the-top suspensions, zero-fun policies, and exaggerated panic. His role is small but iconic—distinguishing himself as the only character in the series with a name that sounds like a motivational sales pitch gone rogue.
