Captain Underpants (character)

"Tra-La-Laaaaaaaa!"

- Captain Underpants' catchphrase

Captain Underpants is a superhero.

As a comic book character
George thought of the idea when he and Harold were in the treehouse. He said that most superheroes look like they're flying around underwear, but Captain Underpants really was flying around in his underwear. Harold said that he could fight with Wedgie Power.

As a real superhero
Mr. Krupp had blackmailed George and Harold into doing backbreaking slave labour for him every day. The boys soon got fed up, so they ordered a 3-D Hypno Ring to hypnotize him. Four to six weeks later, the ring arrived. At Mr. Krupp's house the next day, the boys arrived very late and claimed it was because they were trying to figure out the secret of the ring. They let Mr. Krupp, but he became hypnotized. After hypnotization, George and Harold made him give back the video that was the cause of them doing the work, and then had some fun. They hypnotized him into a chicken, a monkey, and then Captain Underpants.
