Beloved children’s author and illustrator Dav Pilkey has been capturing young readers’ imaginations for over 30 years with his quirky characters and humorous stories that promote literacy, creativity and self-expression.
Best known as the creator of the bestselling Captain Underpants and Dog Man book series, Dav Pilkey’s unique drawing style and talent for writing from a child’s point of view has earned him legions of enthusiastic fans. His award-winning books have sold over 200 million copies worldwide and have been translated into over 30 languages.
Born in Cleveland, Ohio in 1966, Pilkey showed creative promise from a young age despite struggles with ADHD and dyslexia growing up. As a child, he spent much time alone, making up stories and drawing his own original comic books to entertain himself. This early passion for storytelling and illustration set the stage for his future career.
Pilkey first captured the public’s attention with the creation of Captain Underpants – a superhero born when he doodled a face on his elementary school homework. The Captain Underpants book series (launched in 1997) was a breakout success and cultural phenomenon that had children embracing reading and engaging their creativity.
The positive reception inspired Pilkey to continue developing his one-of-a-kind style of innovative storytelling that blended his artistic vision and humor. In 2016, he debuted Dog Man to resounding approval. Starring part dog, part man crimefighter Dog Man and his human friend Li’l Petey, the graphic novel series made history as a #1 New York Times bestseller.
Over the years, Pilkey’s body of work has garnered acclaim from critics and readers alike. His titles have received dozens of awards including Children’s Choice Book Awards in the states and internationally. He continues to dream up new books for his fans all over the world – delighting them with his quirky imagination through his drawings, jokes and stories.
Now based out of Seattle, Washington; Dav Pilkey credits much of the inspiration for his characters to the concepts he himself dreamed up as a lonely child. He strives to create books that kids will love; believing that stories can empower children and help shape their lives in a positive way. Pilkey continues this important mission – bringing fun, laughter and the transformative power of reading into homes and classrooms for decades to come.
The Captain Underpants series consists of 12 installments, as well as a few spin-offs. Here’s a quick rundown:
Pilkey has also published companion books like The Captain Underpants Extra-Crunchy Book o’ Fun puzzle and activity book and The Adventures of Super Diaper Baby, chronicling the crime-fighting adventures of Captain Underpants’ alter ego as a baby.
While each Captain Underpants book has unique characters and adventures, there are some classic elements that tie the series together:
The two main characters, fourth graders George Beard and Harold Hutchins, are best friends and next-door neighbors who love pulling pranks and telling silly jokes. Their comics about a superhero named Captain Underpants end up accidentally bringing him to life. Their hijinks drive their stern principal Mr. Krupp to distraction, but it’s all in good fun.
Almost every Captain Underpants book contains pages set up in panels like comic strips, with instructions for readers to “flip” the edges back and forth to animate a key action scene. These “Flip-o-ramas” encourage interactivity and bring Pilkey’s original drawing style to life.
Let’s face it, Pilkey knows what makes kids crack up, and potty jokes are always a hit. Toilets and bodily functions pop in one way or another throughout the series. Even Captain Underpants himself gets his powers from drinking “Extra-Strength Super Power Juice” which is essentially a concoction of worcestershire sauce, ketchup, and Diet Cola mixed up in the school toilets. Yuck and yum!
The Captain Underpants series keeps one foot firmly planted in its comic roots. Scattered throughout the chapter books are pages of original comic strips depicting the adventures of Captain Underpants, often with speech bubbles, thought bubbles, and onomatopoeias like “SPLAASSHH!” floating across the page. These maintain the books’ visual flair.
So where did Pilkey come up with the idea of an underwear-clad superhero fighting talking toilets? In several interviews over the years, he shared that many threads of his own life found their way into Captain Underpants’ adventures:
As a child, Pilkey struggled in school with reading, writing, and attention difficulties related to dyslexia and ADHD. He was even kicked out of class for being disruptive. Drawing silly comics was a creative outlet for him, and that love shines through his illustrations for Captain Underpants today. George and Harold also have trouble staying out of trouble at school, channeling their creativity into comics.
Pilkey credits his funny bone to his father, who loved broad physical comedy and making people laugh. He brought that slapstick sensibility into his comics as a kid and later into Captain Underpants, filling the books with all sorts of zany action.
The author grew up loving superhero comics and fondly recalls looking forward to Saturday morning cartoons about his favorite crime fighters. Echoes of this fascination can be seen in Captain Underpants’ready willingness to don his cape and his mask and fight for truth and justice. What kid wouldn’t want to create their own superhero?
Considering that the series debuted decades ago, why do twenty-first century kids still devour Captain Underpants? There are a few reasons these books stay relevant:
As any mischievous prankster can attest, George and Harold embody a playful, rebellious spirit that resonates with children. What kid wouldn’t want the power to hypnotize their demanding teacher into temporarily becoming their comic book creation, even if the results get out of hand? The lead duo models creativity and friendship in relatable ways.
There’s never a dull moment in the Captain Underpants books. Just flip through the heavily-illustrated pages of any book in the series, and you’ll see that Pilkey packs each installment with tons of silly action, vibrant colors, zany sound effects, and rapid-fire jokes. There’s no room to get bored!
Teachers have found that reluctant or struggling readers often enjoy the Captain Underpants series because the frequent visual humor makes the text less daunting. The engaging stories and the fact that George and Harold are not ace students themselves also helps. The series cleverly promotes literacy and self-confidence through laughter rather than discouragement.
If you’re looking an irreverent and refreshing adventure series overflowing with smarty-pants humor, look no further than Captain Underpants! Dav Pilkey has created enduring characters that both entertain and speak to the inner prankster in many of us. Not to mention showing us that superheroes can fight bad guys with little more than tighty-whities and a commanding snap of elastic waistbands! So visit your local library or bookstore to join George and Harold on your own laugh-out-loud reading quest – I bet Captain Underpants himself would give it two under-thumbs up!

Dav Pilkey employs a wide range of age-appropriate humor in the Captain Underpants series, from silly wordplay to potty jokes to exaggerated illustrations. Important elements include funny names, absurd plot points, witty dialog, ridiculous villains and plenty of comic misunderstandings. The broad physical comedy and gross-out elements specifically appeal to developing senses of humor.
In the first Captain Underpants book, George and Harold hypnotize their principal Mr. Krupp to turn into the super-powered wedgie-fighting hero Captain Underpants anytime they snap their fingers. Though Captain Underpants has no actual superpowers aside from superhuman strength granted by the writers’ imaginations, his enthusiasm and obliviousness make him a formidable if bumbling defender against villains.
Yes, Captain Underpants’ primary recurring arch-nemesis across the book series is Professor Pippy P. Poopypants. The brilliant but cruel and silly named scientist often attempts to get rid of laughter entirely or shrink Captain Underpants out of jealousy over the hero stealing his spotlight. Their battles highlight the contrast between Professor Poopypants’ cold logic and Captain Underpants’ boundless joy.
George and Harold are the two fourth grade boys who created Captain Underpants through their powers of imagination and hypnosis on their principal Mr. Krupp. As the series progresses readers learn about their home and school lives while they also get up to mischief with pranks and comics. Ultimately their strong friendship and creativity not only fuel the adventures but also help defeat the various villains.
While centered on lightweight goofy fun, the Captain Underpants series also promotes positive messages about creativity, resourcefulness, innovation, standing up to bullies, and the power of laughter. George and Harold especially learn skills to channel their playful imaginations and resolve problems that serve them well on their adventures.
There is no definitive best book in the beloved series since Dav Pilkey does an excellent job of maintaining the quality and humor across new adventures. But many readers especially enjoy Captain Underpants and the Perilous Plot of Professor Poopypants and Captain Underpants and the Wrath of the Wicked Wedgie Woman for the especially absurd villains. New readers might start with the very first book.

As an early chapter book series written at about a third grade level, it should provide the right mix of challenge and entertainment.
