Role in the SeriesEdit

Captain Underpants was originally a superhero created by George and Harold in their comics. However, after George and Harold hypnotize their principal Mr. Krupp, they accidentally make him believe he is Captain Underpants. "Captain Underpants" goes out to fight crime, and after he is rescued by the boys, he is turned back into Mr. Krupp after George got his head wet. However, due to the hypnosis process, Mr. Krupp turns into Captain Underpants whenever he hears someone snap their fingers, and turns back when his head gets wet.

Although originally being simply a mere mortal, he gains superpowers after drinking alien super power juice in the third book. Although George and Harold often find the hypnosis inconvenient, it often proves useful to stop the evildoers that threaten the world.


Captain Underpants is bald and wears nothing but white underwear and a red cape with small black dots.


Captain Underpants' personality is opposite of Mr. Krupp's. He is fun, caring, a bit dim-witted, and loves children. He is good friends with George and Harold.
