About Captain Underpants

Captain Underpants is the creation of American author and illustrator Dave Pilky.

After struggling with dyslexia as a child, Pilky found himself often drawing comic strips as a way to tell stories.

In his adult life, he became an author after publishing his first book “World War Won,” in 1986.

It wasn’t until the release of Captain Underpants in 1997, however, that he began to see mainstream, publishing success.

Captain Underpants is beloved for its snappy humor, fast pacing, and hilarious characters. Some of the main themes of the series revolve around the power of imagination.

Harold and George—the two central characters of the book—use the power of their imaginations to create what was once just a character into a reality.

The books remind children of the importance of imagination.

Another important part of the books is the theme of authority and the boundaries between child and adult relationships.

Harold and George are quite troubled kids, who often face off against their principal due to their behavior.

However, much of their bad behavior is rooted in humor, and the novels explore how this mischievous nature can be a positive thing when prevailing against difficult authority figures.

Captain Underpants is one of the most popular children’s book series in the world, and the success of Pilky’s next series—Dog Man—has only added to this acclaim.

Now let’s take a look at the reading order!

  • Doesn’t work so well as a standalone entry.

This was the last entry in the series, as Dave Pilky shifted his focus to work on the Dog Man series.

Final Thoughts

In short, you can easily read the Captain Underpants novels in publication order.

If you do this, you’ll get a good understanding of the series and the characters, as well as the underlying themes that build with each book.

However, I hope that I have illustrated how almost all of the novels can be read as standalone, and you won’t be too out of the loop!

I’d only recommend reading Captain Underpants 6 and 7 together, and 9 and 10. I’d also recommend reading the final entry last of all, as it wraps up the series.

I hope that this guide has given you a good idea of the reading order of this series, and you’re not all set to get started delving into the whimsical world of Captain Underpants. Happy reading!
